TL;DR: In a nutshell, I REALLY like the Omnicharge 20 device. I validated virtually all of the published features and had a chance to examine the internals, and was VERY happy to see super-clean, heavy-duty printed circuit boards with near immaculate soldering, no solder balls and well-aligned components. Pros for battery safety and individualized cell balancing circuits, a very informative real time OLED display, HVDC capability, wide charging voltage input support, and adjustable Direct-DC output. The compact size is superb and the PCB design is one of the best I’ve seen on ANY device in this class. Cons for the use of a modified sine wave AC inverter, no user serviceability whatsoever, and no way to perform firmware upgrades. Given the quality inside and feature set, this pack is worth $300.00 and I certainly have no regrets – even after I tore mine open to write this review.
----- MAIN REVIEW -----
Given the number of features inside the Omni20, I’ll break-up my review by feature, so you can jump immediately to the section that interests you most.
The unboxing experience for the Omnicharge is quite pleasant. The device ships in a shrink-wrapped, heavy-duty black box with a decent plastic molded liner. The Omnicharge itself is protected from scratches in a soft-touch white plastic sleeve. Inside, you’ll find the Omnicharge 20, an Omnicharge-branded compact universal AC wall wart (100-240VAC, 50/60Hz) providing 19.0VDC at 2.37A (Tip Positive with a 5.5x2.1mm Barrel Plug). The wall wart is made by Shenzhen Honor Electronic Co., LTD. It is efficiency level VI, allowing it to be imported into the USA. The wall wart also has a collapsible 2-prong plug making it even easier to pack. There are a plethora of included adapter plugs for every holiday occasion, including an Apple MagSafe 2 cable and a Microsoft Surface 3/4/Book Connect cable. A cheap and hard-to-read owner’s manual replete with micro-printing accompanies some Omnicharge stickers, and that pretty much completes the box.
* Physical Characteristics: Omnicharge 20 weighs about 1.5 lbs. Its dimensions are 5.0 x 4.8 x 1.1 inches. FCC Certified (2 IDs, 2AJ8J-23 and 2AKPK-23), CE certified and ROHS Lead-Free electronics.
* Operating range: (unverified) Published specs are – Charging 50 to 113F, Discharging -4 to 140F. There is a small internal 12V/120mA fan that makes virtually no noise when running.
* AC/HVDC Outlet: In AC mode, provides 120VAC/60Hz modified sine-wave. In HVDC mode, provides 150VDC (675mA Max). Continuous power out = 100W, Peak output power ~ 105W (< 1 second), Surge output power ~150W (< 0.1 seconds). HVDC works slightly better than modified AC for switching mode power supplies (SMPS), but can’t be used with older (and usually much heavier), non-SMPS supplies (or inductive loads like fans). If your adapter is heavy for its size and has a large internal transformer, it probably won’t work with the HVDC mode. See Omnicharge’s website FAQ for more details on HVDC support.
* USB Outputs: Top USB port supports DCP mode only and can provide 5V/3A. The bottom USB port supports Qualcomm Quick Charge 3.0/2.0/1.0 for 5V/3A, 9V/2A and 12V/1.5A. 20V Quick Charge is not supported. The lower USB port can also provide Apple 2.4A support and basic DCP, but no other charging protocols are supported (no Samsung AFC, MTKPE, Huawei FCP or Dash VOOC). The USB ports can be turned on or off through the UI, and turning off USB will also disable the Qi wireless charging capability.
* Qi Charging Pad: Can supply 5V/1A (5W) max. WPC certified. No Samsung Wireless Fast-Charge capability. Hideously inefficient, but quite convenient if you’re a Qi fan. The coil is centered towards the back center of the Omnicharge unit, but the coil’s center location is not marked on the top case, so you have to fish for it a bit. Unfortunately, Qi’s becoming less relevant these days, being surpassed by newer, more efficient wireless charging technologies. Don’t buy Omnicharge based on its Qi charging capability. It’s candy and it’s a little boring given the bevy of other awesome features packed into Omnicharge. It also may not work with your Samsung S8, due to Samsung S8-related design problems. This is, in my opinion, Omnicharge’s least-useful feature.
* Battery Characteristics: Six NCR18650GA Panasonic cells, placed in 2S3P configuration, each cell individually protected and cared for by its own SII Semiconductor S-8209A protection IC. Cells total 73Wh (20,400mAh at 3.6V nominal). Life-cycle rating is 500/70%. The battery is sealed inside the case and is not chainable or user serviceable.
* DC Charging Input via 5.5 x 2.1mm Barrel Port: Wideband voltage input, can support anything from 4.5V to 36VDC, and will pull no more than 46W regardless of the input voltage. Published spec is 2W to 45W max. DC charging input slowly ramps-up to max current as Omnicharge tries to learn the maximum power your charging adapter can provide. You can charge Omnicharge with nearly any other DC power source, including other portable batteries. This is, in my opinion, Omnicharge’s second-best design feature.
* Direct DC Output: Adjustable via OLED menu in tenth-volt increments, from 1.0V to 24VDC, up to 3.5A (70W maximum power). This is, in my opinion, Omnicharge’s BEST feature.
AC/HVDC DETAILS AND ANALYSIS
The Omnicharge provides two modes of “AC appliance” support: Modified AC sine wave (120VAC/60Hz) and High-Voltage DC (150VDC). I tested both modes compared to the “real” AC voltage provided by my utility company (119.5VAC/60HZ). My testing revealed that both modes are remarkably similar efficiency-wise. The AC mode worked better for smaller loads, up to just about 45 watts, where the HVDC mode started to be more efficient the rest of the way to 100W max. I measured 0, 250mA, 500mA, 750mA, 1A, 1.25A, 1.5A, 1.75A, 2A, 2.5A, 3A and 3.5A using a Phihong model PSA120U-240 AC SMPS adapter attached to a BK Precision 8500 300W Electronic Load. I’d attach the results table to this review if only Amazon could be bothered to make the review entry process more capable for people like me. Sorry, I’m not going to try to convert my whole XLS to text for this review – I’ll only provide 2 data points – MIN and MAX loads:
PHIHONG SMPS DC LOAD = 0A, REAL AC (119.5V) AMPS = 44.6mAAC/5.32W, OMNI20 MOD AC (125.4V) AMPS = 13.3mAAC/1.66W, HVDC (149.7VDC) AMPS = 12.3mA/1.84W
PHIHONG SMPS DC LOAD = 3.5A, REAL AC (119.5V) AMPS = 813.7mAAC/97.24W, OMNI20 MOD AC (125.4V) AMPS = 804.4mAAC/100.87W, HVDC (149.7VDC) AMPS = 675.4mA/101.1W
See attached pictures for Oscilloscope measurements of AC and HVDC stability at both minimum and maximum loads. Omnicharge held its own, even under maximum load. There is considerable noise on the HVDC output, even when unloaded (and especially when loaded < 4 watts), but this is not generally going to be a problem if you think about it… That noisy HVDC is going into straight into another switching-mode power supply that’s going to polish and filter it down into the DC output needed for the attached device, so the HVDC doesn’t need to really be super-clean anyway. Why waste space on big capacitors and coils to unnecessarily filter DC that’s going to be filtered again anyway? When it comes to HVDC polarity, I’ve identified positive and negative in most of my pictures where the plug socket connections are visible. Positive is on the bottom-most slot of the AC plug, and Negative is in the top-most slot. Ground is not connected or used at all, and the ground plug hole is not isolated from the rest of the internals, making it unfortunately easy for chunks of crud to get inside and foul the electronics. A rubber plug to seal the AC receptacle would have been a nice touch.
The Modified AC is typical of most modified-AC circuits, and is generally a pain in the butt to measure because it acts more like a messed-up square wave than a sine wave. “RMS Volts?”, uh, sure… Still, though, Omnicharge’s modified AC inverter does a decent job, even when supporting a 100W load. Again, see attached pictures showing the modified AC square-wave under maximum load.
Omnicharge provides two USB ports, each with different capabilities. The top-most USB port supports standard USB DCP (Dedicated Charging Port) mode up to 3 Amps. I quite happily measured 5.1974VDC on the top port, so it’s well-powered to allow usage of even those super junky, high voltage drop USB cables that you technically should throw into the trashcan. The lower USB port supports Qualcomm Quick Charge 3.0 (up to 12V/1.5A), DCP mode, and Apple 2.4A mode. The lower port measured 5.1968VDC in basic DCP mode as well, so that port’s equally well-designed to handle poorly designed and/or overly long USB cables. One thing that annoyed me slightly about Omnicharge’s USB ports was that unless they’re loaded to around 30mA, they’ll shut off on you because Omnicharge just assumes nothing is using the current there. I’m pretty sure this annoyance can be turned off by telling the UI to not automatically shut-off after x-amount of time, but I didn’t do deep exploration here because it’s a corner usage scenario anyway. It could also be argued that this is actually a feature, not a bug. See attached pictures from my USB protocol analyzer for more info.
DIRECT DC OUTPUT DETAILS AND ANALYSIS
The Omnicharge’s best feature in my opinion is the ability to provide direct DC output to an attached device, thus avoiding all the modified AC efficiency and conversion losses. Using this mode to power your doodads instead of HVDC or AC Inverter will massively increase your mileage with Omnicharge. If you can find a cable to go from Omnicharge to your device, and your device is cool eating DC voltage from a non-OEM power supply, Omni20 should propel your device much further than AC or HVDC would. The direct DC output can be adjusted anywhere from 1V to 24VDC in 0.1V increments using the easy-to-learn OLED display. You’ll even get a confirmation warning to change the output voltage before it takes effect and potentially roaches your device. Use your brains here, and make 100% certain you know what your device needs. You don’t usually get a second chance, and while you won’t likely damage Omnicharge because it is LOADED with protection circuity, you can instantly and irreparably destroy an attached device by feeding it more than it was designed to eat. Watch your step when using this very capable and insanely awesome capability. Direct DC output noise is typical of what you might expect with a POL (point-of-load) switching power supply. There IS noise, but it is well-filtered here unlike the HVDC output. It’s certainly not as clean as a real battery, but it’s at least as good as any wall adapter would provide (if not better).
DC INPUT CHARGING DETAILS AND ANALYSIS
Omnicharge can consume anything from 4.5 to 36VDC at up to 46W max. This is the second-best feature in my opinion. I tested 4.0, 4.5, 5, 10, 15, 20, 25, 30, 35, 36 and 40 volts to observe how Omnicharge would react and see how much power it pulled at each voltage. I started out with a battery at only 20%. 4.0V did nothing, like I expected and hoped. The unit woke up at 4.5V and pulled a whopping 1.4W after ramping up to 310mA over a period of 12 seconds. At 36V input, Omnicharge ramped-up to 1.26A over a 12-second period, stopping at 45.36W. At 40V, Omnicharge failed to pull any current whatsoever or even acknowledge my existence. This was, of course, expected and appreciated. The only other thing worth noting about this very robust and capable charging feature was that different input voltages resulted in different ramp-up times, ranging anywhere from 8 to 32 seconds. The longest ramp-up was for 25VDC and took 32 seconds to get to 45.25W. The shortest time was 8 seconds for 35VDC, which ended up pulling 45.15W. This slow ramp-up feature is Omnicharge's "Maximum Power Point Search Technology" at work. Very clever, and quite effective at learning the behavior of the charging source (or solar cell).
QI CHARGING PAD
Omni20 features a Qi-capable, WPC certified, 5V/1A (5W) wireless charging pad centered near the middle-back of the top case. There’s no marks on the case directing you to the center of the coil, so you’ll have to go fishing for it to find its magical spot. Once you find the spot, the wireless charging icon will start FLASHING (not stay full-on). This means you’re successfully being lazy instead of using a USB cable to charge your device which is WAY more efficient and faster than Qi. But hey, who am I to judge? Anyway, my opinion is that Qi’s on its way out, in favor of newer, faster and more efficient wireless charging tech. I don’t personally believe adding the 5W Qi coil to the Omnicharge was really worth the additional BOM cost (or weight). That said, I did test it, and it worked nicely as advertised. If you turn off the USB ports, you’ll also turn-off the Qi charging coil – they can’t be individually controlled.
OLED DISPLAY AND USER INTERFACE
The high-contrast, well-designed UI makes using the Omnicharge super simple. Information is presented to you in real-time, where you can see:
- Current function(s) being used (Adjustable DC output, AC output, HVDC output, USB output, Charging input, Maximum charging rate, Solar charging, Temperature protection, Overpower protection, Overvoltage protection)
- Battery capacity remaining in Watt Hours
- Battery level (0-100%, +/- 1% accuracy)
- Battery Temperature
- Battery Input Power
- Battery Output Power
- Charge time remaining at current rate (either charging or discharging)
Three buttons provide the means to interact with the Omnicharge. A single short-press on the power button turns the unit on (which is a little TOO easy to turn on, in my opinion - I think it should be recessed or have a protective collar around the button making it harder to press accidentally). The other buttons activate features or allow you to navigate the setup menu. The buttons could use some additional fit and finish work in my opinion. I have found my Omnicharge 20 turned on inside its carrying case before, because the zipper on the case just lightly touched it... luckily, the Omni20 is normally configured to automatically turn itself off after an amount of time with no load detected, so this shouldn't be a big concern in most cases.
FCC CERTIFICATION AND OMNICHARGE HISTORY
Omnicharge came to you from an Indiegogo campaign that funded $3,184,687 on September 4, 2016. Actually, it was mostly finished well-before that time, as the developers front-loaded the design and development costs long before the Indiegogo campaign that was used to commercialize and kick-start mass production. They did you Indiegogo-ers a real solid by doing this, too. They paid for all the heavy lifting in design and development themselves, worked-out all of the PITA power design and heat dissipation problems, and gave you a massively functional unit when they shipped. I wish more start-ups did this, and I could rant for days about the thieves that plague Indiegogo and Kickstarter… But, I digress. Omnicharge first came to life bearing the FCC ID of 2AJ8J-23, issued to Tianjin Synergy Groups Co., Ltd located in Tianjin, China in November, 2016. This company applied for a second, new FCC ID in late December, 2016 and was granted FCC ID 2AKPK-23 for Omnicharge, Inc., located in the USA. The application letter states “The equipment is electrically identical. The only change being the label on the device. The original test results, technical information and relevant documents continue to be representative of and applicable to the changed equipment.” When you ask for a duplicate FCC ID based on an existing grant, the FCC won’t automatically copy-over all test reports and exhibits to the new ID – they stay attached to the original granted “parent” ID. So, if you want to see the Omnicharge’s FCC submissions for the Omni20, you’ll need to search for FCC ID 2AJ8J-23. Why the two ID’s? This was likely done to protect IP in both China and the USA. Tianjin Synergy Co. is located in China, and Omnicharge, Inc. is located in the USA. By having twin grants for the same design, they can use their China presence for design and IP protection in China, and the USA presence can be used for marketing, etc… This practice has been used fairly frequently over the past few years, and in some cases, it can make trying to track down the “real” manufacturer of a device an unnecessarily big PITA. You can thank me later for sifting through multiple PDF’s on the FCC’s web site to find this, free, publicly-accessible data for you in advance 😊. When you visit the FCC’s web site and conduct an FCC ID search for 2AJ8J-23, you’ll find Omni20’s Owner’s Manuals (an older copy), RF Testing Reports, RF exposure test results, FCC ID Applications, Test Setup photos and mediocre-quality pictures of the internals all in PDF format. Sorry, no schematics or block diagrams for us – the OEM’s can request that these FCC-required documents be permanently listed as confidential and they are not available for download.
INTERNAL INSPECTION AND ANALYSIS
I saved the best for last. First off, just know that getting inside Omnicharge is essentially a one-way ticket. I won’t bore you to death with all the reasons why you shouldn’t try and go inside, but just know that if you open it up, it’ll never go back together as neatly and cleanly as it came to you from the factory - and you’ll void your 1 year warranty. Getting inside was tough, even after reviewing some pictures from the FCC. It required some real effort because the designers used some super-tough white RTV silicon adhesive to goop-up each of the four corner clips just before they snapped the case halves together. After the glue cured, it effectively kept the plastic clips from flexing, thus permanently locking the two case halves together. Additionally, they applied drops of the same goop to the top and bottom of the 6 battery cells, effectively using the battery pack to glue the case shut, top-to-bottom. What a mess. I ripped apart two of the clips and severely crippled a third -- and I almost damaged the main battery connector when I pried the case open, and the battery pack decided to stay glued to the top case, while the electronics stayed screwed into the bottom case. Luckily, though, I stopped just in time to gently unplug the main battery without ripping the connector’s header off of the mainboard. Omnicharge does NOT get any props when it comes to serviceability for this device. This thing is made to be shut and sealed forever, hampering recycling efforts and denying users the ability to update firmware or replace worn-out battery packs. This is my least favorite thing about the Omnicharge design. Also, the OLED display is glued-in, permanently entombed inside the Omni20, so take extra care not to damage your Omnicharge OLED display -- There will be no fixing it if you damage it (or the front panel buttons, for that matter).
Inside you’ll find 4 main circuit boards: The display electronics, the main Logic circuit board, the main POL Power circuit board and the Battery Management circuit board. I’ve attached pictures of all of the boards to this review. The display electronics board connects to the logic board via a 16-pin flex cable. It is not user-replaceable as it is permanently glued in place into the front bezel along with the push buttons. Damaging the push buttons or the display would essentially be devastating to the unit and your ability to use it.
The Logic PCB holds the brains for the whole operation. There’s a single ST Micro ARM STM32F103 micro-controller and associated clock and power supply on this PCB, as well as the NEGATIVE contact for the HVDC function. There is no obvious interface connector showing a way to flash firmware onto the STM32, so I’m not sure how they do that, unfortunately. There are no parts located on the bottom of this PCB, so I didn’t take pictures of that side. The logic PCB is secured to the Power PCB underneath using 4 stand-offs and has an additional larger white flex cable that connects to the lower Power PCB.
The Power PCB is basically a programmatically controllable POL Switching Power Supply and an modified-AC inverter. The board is extremely dense and VERY busy. It took someone a lot of time and energy to concoct this design, and it IS pretty darn amazing. The main 6-cell battery connects to this PCB, and this PCB houses ALL of the SMPS electronics, I/O protection circuitry, wireless charging electronics and USB electronics. A cute little 12V/120mA fan provides some amount of minimal forced-air cooling when the unit heats up, and this fan is VERY quiet and unobtrusive when it runs (only when needed, by the way). The Power PCB also holds the POSITIVE contact for the HVDC output.
The Battery Management board does its own thing in solitude, quietly focusing on the six precious NCR18650GA Panasonic cells, placed in 2S3P configuration. Each battery cell is individually protected and cared for by its own SII Semiconductor S-8209A protection IC. The six cells total 73Wh (20,400mAh at 3.6V nominal). Life-cycle rating is 500/70%. There’s a single thermistor glued to the middle-center of the battery pack, providing thermal intel back to the smart electronics for safety and fan control. The SII protection IC’s are configured with discharge cell-balancing enabled. Current is passed to the Power PCB via a 6-pin cable. See pictures for other details.
In terms of quality, I found ZERO complaints about the PCB construction. No solder balls, no cold solder joints, no excessive flux leftovers. I didn’t see a single thing inside that creeped me out, and I creep-out pretty easily when it comes to poorly-manufactured electronics – especially ones that pack so much energy into this small of a space.
SUMMARY OF PROS AND CONS
* This thing is real and it works as advertised!
* Compact size is fantastic and airplane-approved!
* Safety, Safety, Safety. For all inputs and outputs.
* The QA on the internals really stands out. Omnicharge cared and it shows when examining the guts.
* This is basically a battery-powered, extremely portable power supply that can be recharged from almost any other power supply.
* Comprehensive OLED display shows real-time input and output status, time remaining, battery capacity and temperature, and active functions
* See the full feature list at Omnicharge.co for a detailed list of the “pros”!
* Super expensive ($300)
* Absolutely not user serviceable at all. If you break the OLED display or the push buttons, it’s essentially trash.
* If you damage a USB port, there’s no way to fix it. Don’t you DARE plug one of those miniature USB lights into these ports; if they bend the pins inside the USB jack, it’ll never work again.
* The battery pack can’t be changed (even though it could easily be changed, if only you could get inside the case to change it without ripping the plastic case apart).
* No way to update the firmware. You get what you get from the factory, so unless you get a replacement unit with newer firmware, you’re forever stuck with whatever version it shipped with.
Cheers, and enjoy your new Omnicharge, but don’t try to open it up. 😉
I am an early backer of this product on Indiegogo and the Omni 20 has in every way lived up to if not exceeded my hopes and expectations!!
What can this thing charge and power? This is probably one of the foremost questions we all had or have when looking at this device for the first time and as such I will answer it as the first part of my lengthy review. The Omni 20 can charge and/or power: Laptops, smartphones, dumbphones, wireless headphones, wireless headsets, portable speakers, televisions, VCR players, DVD players, Blu-ray players, Roombas, drones, your cat*, your hamster*, tablets, lamps, bathroom appliances requiring less than 100W like straighteners and electric toothbrushes (not likely any hair dryers due to their high wattage requirements), mp3 players, small kitchen appliances, and much much much much much much much much much much much much much much more via it's USB ports, AC outlet, DC Output, and Qi Wireless capabilities! In the comments, I will include a YouTube link for my full 20 minute review of the Omni 20 for those of you who actually want to see every feature in action instead of or in addition to a bunch of writing!
I am happy to say that this is the coolest piece of technology I have ever owned. This is a pretty bold statement on the part of someone who has owned and tested 12 laptops in the past year and who enjoys a wide array of hobbies entailing technological products, but it is true. I have owned several other power banks including the equal in capacity but $270.00 cheaper Easy Acc Monster 20000mAh power bank and a couple of Anker power banks, but those and every other battery bank on Amazon right now pale in comparison in most aspects to the features and utility that the Omni 20 boasts (except for USB-C capability, only for now, read below in my June 5th entry for more detail on that)!
It has two USB ports, one with Qualcomm Quick Charge 3.0 technology and the other being a 5V/3A. It also boasts Qi wireless charging, DC Output via its barrel socket up to 24V's (which is more than adequate for most ultrabooks and laptops including all Apple MacBook and Microsoft Surface products). And, for the grand finale: The Omni 20 is the first power bank this small and with this much safety built in to have 120AC/150HVDC A and B Socket Type AC outlet that supports 100W continuous output!!!!
This AC wall outlet feature is what made me decide to purchase it. Having a AC wall outlet with you on the go everywhere you visit is way more useful than any of us could have imagined before having such a device available. The first example I will give of its utility is telling you about the laptops I have used it with. I have used this AC outlet to charge my old 2015 Macbook Air 13", mu current 2015 Macbook Pro 13", and even charge my 2017 Alienware 17 R4 gaming laptop--- sort of--- Allow me to explain but feel free to skip the next couple of paragraphs for more non-gaming laptop Omni 20 info:
Although the Alienware 17 R4 with 1070 graphics card is powered by a 240 watt AC adapter, it does not require 240 watts to be charged or to run continuously. When gaming or doing other high intensity computing activities, this laptop's power requirement will shoot above 100W sustained and thus overpower the 100W continuous max limit of the Omni 20. However, when it is fully charged, I have been able to do basic productivity and web browsing activities as it is only trickle charging at around 50W give or take from the Omnicharge to sustain its 100% battery. When the battery is drained and it actually needs to be charged, it can be charged by the Omnicharge if the laptop is asleep or turned off as it will then require under 100 watts to charge. In the video, I show the 90W of continuous power it was using requires its drained battery was being charged, but at the time of filming I had not figured out that you can actually run the laptop with the Omni 20 hooked up for basic every day multitasking when the laptops battery is at 100% already! I have made a video showing all of the ins and outs of charing and powering high-powered laptops on my YouTube channel I mentioned above, so that may be worth a watch if this topic is one of interest for you. To sum up the points above:
High-Powered Laptops/Gaming Laptops:
1. The Omni 20 can charge an emptied gaming laptop battery while the device is asleep or shutdown.
2. The Omni 20 can sustain the gaming laptop if it is already charged to 100% for basic everyday usage when you plug it into the Omnicharge.
3. You cannot use the Omni 20 to charge the laptop while gaming or doing high intensity activities, the wattage demand becomes too high for the Omni 20 to sustain and its overpowered protection feature will be activated.
As for other AC powered devices, in the first video I made I showed hooking up a 32" television, 95W Hair Straightener, AC powered USB Hub, and even a power strip with multiple devices attached, all without the Omni 20 even breaking a sweat!
The Omni 20 has a fan built in that turns on when the device exceeds a certain temperature and this is something I personally appreciate as I come from a world of high temperature devices with my laptop gaming. The fan can be turned off, however, with the Omnicharge's built in Silent Mode that is selectable in the menu. I would not recommend doing this for an extended period of time as the fans are designed to turn on and operate at certain temps for a reason, but this feature will be handy for those of you who may need to utilize this in a quiet setting like a conference or a lecture as the fan does get a bit loud and whiny when the Omni 20 is working hard. The fan isn't loud enough to penetrate the sustained noise in a coffeeshop, but in a quiet lecture hall or meeting the noise of the fan may cut through.
As this is a power bank, you of course have to charge the device itself. What makes this thing so awesome, is that you can charge it via its included barrel plug AC wall adapter, included barrel plug USB cable, via a laptop charger using the included adapters. As the pictures on Amazon show, you get every kind of adapter in the box you will need (except for USB-C until Omnicharge comes out with a module or adapters). It charges well via solar panels as well and as you probably guessed, I did make a video of this available to view in my YouTube channel! It is pretty epic actually, the idea that you could be off the grid for this for days by charging it via a Solar Panel if the sunlight conditions were ideal.
The menu, navigation, and display/notification icons are absolutely stellar. The OLED screen does a fine job of displaying all of the information you need and the nice thing about it is that it allows anyone to pick this up and use it according to the depth and interest they have in its features and info. I can hand this to my technology-distrusting father and he can plug in his phone and get it charging with the simple push of a the power button. For someone like me who really likes to know everything about the device and what it is doing, it comes with an easy to read paper manual and the Omnicharge staff is really great about answering emails and questions in a timely fashion.
Essentially, this is a device for the whole family and not just those who are tech savvy! My younger siblings love using it for charging their phones and tablets in the living room while being able to hook up a power strip to power other things like lamps, electric toothbrushes, and TVs just for fun! This Omnicharge has been in my school bag every day as I do my clinical rotations and attend lectures for nursing school. I cannot tell you how many times I and fellow cohorts have had laptops die on us during 4 hour long classes or 12+ hour clinical experiences. This device is going to be the envy of my class and I am guessing several of my cohorts are probably going to end up buying Omni 20's or 13's for themselves!
Take it from a nursing student/ gamer/ video maker/ social media addict/ tech nut, you are going to find some use for this device no matter what your occupation or hobbies might be!
If this word soup review has helped you, please do give me a like so others can see this too. Again, the video reviews I have made really lay it all out for this product so do click on the link in the comments if that interests you. I will be making more Omni 20 videos later on as well as people tell me what they want to see and new accessories/changes come out!
Keep in mind that at the time of this review (April 1st, 2017), Omnicharge is a BRAND SPANKING NEW gleaming technology company freshly graduated from crowd-funded company status. Give it time, and this beautiful device and its progeny are going to be available the world over in all sorts of configurations, sizes, and I/O setups!!!
Thank you so much and good luck with your purchasing decision! I hope you like the pictures too!
*No cute fuzzy animals were actually tested with the Omni 20 in the making of this review. ;)

Wow!!! This thing attracts positive attention!! Today, in our first Pathophysiology lecture of the term, I pulled out my 2015 MacBook Pro and this Omni 20 quipped with the MagSafe 2 DC Out cable and hooked it up on my desk. Within 5 minutes I had my MacBook Pro charging via the DC out feature, my friend's HP convertible laptop via the AC outlet, and my iPhone via a USB port! People were looking on, asking questions, and general praise and interest was the reaction! I was also happy to hand over the Omni 13 and Omni 20 I bought for my friends during the campaign and they are both ecstatic about them! However, my friend with the Omni 13 is now wishing she had gone with the Omni 20 since the Omni 13 can't do DC out which means she still has to bring her 2015 MacBook Pro charger with her. She is still happy she doesn't have to stay near wall outlets, though :)
When I first opened up my 2015 MBP 13" for my 2 hour lecture on Pathophysiology and Pharmacology, it had 48%. I hooked it up to the Omni 20 while it was also trickle charging my buddies fully charged HP laptop and my iPhone 5s as well. When I left class, the power bank was completely dead, my laptop had 85%, and the iPhone and HP laptop were both still fully charged even during use! That is amazing! The key thing here to understand is that the Omni 20 didn't just go from 100% to 0% simply charging the devices in that 2 hour span, it did so while powering AND charging two laptops and an iPhone at the same time! THAT is the impressive thing. I was using Microsoft OneNote, Word, and PowerPoint and was on the web looking at the lecture notes and researching the pathology topics the whole time during that class and my friend on their HP laptop was doing the same. I have exactly ZERO regrets about owning this thing right now. I will be back soon with more updates! Cheers!

I have had my Omni 20 for over two months now and it still surprises me with how handy it is at least a couple times of week. Has it changed my life drastically? No. Has it improved the convenience of using a laptop everyday, impacted my choice of study location decisions, and work flow decisions? Absolutely. Having this kind of power on hand at any time is really more wonderful than can be described. Since I last worked on this interview a little over a month ago, the Omni 20 has gotten me through a variety of scenarios including a night-long power outage in which we utilized the Omni 20 for my high-powered USB powered room light for the bathroom (for showering) and for the beside lamp and charging a very starved phone. It worked incredibly for this and I will be posting a short video on my YouTube channel soon about it! I also have had it in my backpack literally 5-6 days out of every week while I have been in school and nursing clincals and it has worked superbly. I have gradually been forgetting what the stress feels like when my computer is dying and there are no wall outlets accessible within reach or available at all in a busy Starbucks on a Saturday morning. Like I said, nursing students (at least in my program, I am sure most others) use our computers absolutely all of the time in and out of class be it note taking, pre-clinical or post-clinical patient charting, and for general homework, study, lecture video viewing, and more. As such, the Omni 20 has been a true enhancement to the most critical piece of hardware in my nursing school supply and has gotten other students and myself out of some tough spots when our computers are dying in the middle of online tests or lectures.
Being totally candid, a feature I am looking forward to, be it a model refresh or an add-on module, is a port for USB-C in and out charging. USB-C is swiftly taking over the market due to its versatility and ability to provide power delivery (PD) to devices requiring less than 100W at peak and as such this Omni 20 would be nearly perfect if it offered such a feature. During their Indiegogo campaign back in October or November, I remember that Omnicharge developers were on the fence about whether they were going to do a barrel plug or USB-C for power delivery. They went with the barrel plug for many good reasons at the time, which included the fact that the barrel plug charger for the Omni 20 can charge the device itself much quicker than a basic USB-C wall plug can and the fact that USB-C still wasn't quite that widespread. Alas, now we are seeing ultrabooks, phones, and other sub-100W powered devices quickly trending towards widespread utilization of USB-C and as such it will be important for the future of Omnicharge and other power bank companies to adopt builds that can provide USB PD for higher powered devices. Upon speaking with Omnicharge customer service at some point a while ago, I remember them mentioning that they were thinking about or already working on a USB-C in and out attachment module for the Omni 20. This will be a joy for 2016 and newer Mac owners and others whose technology is USB-C centric. Keep an eye out for my updated review if or when the USB-C module comes out! This will be exciting because it will mean that you will be able to leave your USB-C chargers and power bricks at home for the device and just take your Omni 20 and a high quality USB-C cable with it!
I have been using it every day for 9 days to give it a full test by charging my Galaxy S6 and Lenovo laptop. I really wanted to love it, but I'm disappointed on several fronts:
1. Poor battery life---On a full charge of 100% on Omni 20, I can only get 4 full charges on my Galaxy S6 instead of 6 promised by Omni. That, I can live with. However, I can only get 70% of charge on my laptop, Lenovo Flex 5. This is very disappointing. I bought Omni 20 mainly because of my laptop as I need it for school and school work.
2. While there are many tip sets included, none work for my Lenovo Flex 5 laptop. It bothers me to find that after paying so much money for the unit, I got a whole bunch of tip sets that I have no use for---none of the included tip sets work for my laptop. Very upsetting!
3. High temperature---Because there is no DC tip set that works for my laptop, I have to use my Lenovo AC charger to charge my laptop from my Omni 20. Both the AC charger and Omni 20 get very hot, at 116 degrees F. For that high temperature, lots of battery power is lost.
With the above-mentioned issues with this expensive Omnicharge, I'm considering contacting Amazon to return it to look for some different product.
