Overall Thoughts And Conclusions
There is really a lot of information & important points that I wanted to share with you for this review, it is a bit lengthy . So I'll share the overall summary up front.
The Good :
- Currently one of the highest capacities of any powerbank offered by name brand manufacturers
- Massive capacity makes this PowerBank a true 'Off the Grid' device that can power your families devices through the entire camping/vacation trip, if used correctly (see next point)
- The quick charge feature , while a huge convenience, must only be used when necessary as the actual usable capacity / charge cycles are reduced by half (50%) compared to what you can get using the Non-QC port (See the Quick charge section for a more detailed explanation)
- The AiPower port does a great job of correctly identifying devices and charging them at their maximum rated speeds
- Despite its massive capacity its not much larger than what I expected ( it is still large) and when I put it side by side to my Anker 16000 mAh PowerBank
Not So Good:
- The massive capacity means its not pocket friendly & it weighs about 1.2 pounds. It should be able to fit in your backpack perfectly though
- As per FAA's official guidelines and restrictions on the max capacity of Lithium Batteries, you cannot carry this PowerBank in your Carry-On baggage - FAA's official limit for batteries is upto 100 Watt Hours. This Powerbank is rated at 111 Watt Hours. You will have to take prior approvals from Airlines before travelling to bring it as carry on.
Total Capacity Test
For this test I wanted to test how much of the advertised 30000 mAh is actually available out of the box . Typically Powerbanks only have around 88%-94% of their advertised capacities because Lithium Ion cells start degrading almost as soon as they leave the production lines. That's just the way the Li-Ion batteries work. To do this, first I drained Powerbank as best I could by charging my devices until it died and then leaving the LED flashlight on overnight to drain the remaining charge . I then charged the Powerbank using an iClever QC 3.0 Charger and measured the capacity transfer using a Drok Ammeter.
Advertised Capacity = 30000 mAh
Measured Capacity = 26754 mAh (89% of Advertised Capacity)
As you can see 89% is still within the expected range , and since its never possible to fully drain a Li-Ion Cell due to protection circuits , there is always 1-3% charge left in them even when they appear dead. So realistically this power bank has somewhere about 91%-92% of its total advertised capacity
Actual Usable Capacity
There are a lot of misconceptions about the true usable capacities of Powerbanks i.e we can simply divide the capacity of a power bank with the capacity of a Phone/Tablet in order determine how many cycles any power bank be used to charge (For example a 2000mAh capacity phone could be charged 30000 mAh / 2000 mAh = 15 times by this power bank) or finding the efficiency by how many cycles you can get from it , however these are not correct.
The correct Electrical formula of the true usable capacity of a Powerbank is given by:
Ampere-Hour (mAh) = Measure of electric charge capacity of a battery typically at 3.7 Volts
Watt-Hour (Wh) = A measure of Electric Energy (That is used to charge your phone)
So total Energy of this PowerBank at 3.7 Volts is :
Watt-Hour (Wh) = Ampere-Hour(mAH) * Voltage
26754 mAh (measured) * 3.7 V = 98989.8 mWh
Now in order to charge your phone , this internal voltage of 3.7V of the PowerBank Cells has to be boosted to 5V by its internal circuitry so that the current can start flowing from the Power bank to the Phone. This conversion of 3.7V to 5V involves some losses. A good conversion circuit can achieve an efficiency of around 90%
Thus total charge available that the Aukey Power Bank can 'Push Out' to your phone at 5 Volts with 90% efficiency :
(98989.8 mWh / 5 Volts) * 0.9 (efficiency) = 17818 mAh
Samsung Galaxy S6 Stated Battery Capacity = 2550 mAh
Samsung Galaxy S7 Stated Battery Capacity = 3000 mAh
iPhone 6s Stated Battery Capacity = 1715 mAh
iPhone 6s Plus Battery Capacity = 2750 mAh
Total Number of charge cycles (0% to 1`00%) this PowerBank can give using the Non-QC Smart AiPower Port :
Galaxy S6 : 17818m mAh / 2550 mAh = 6.9 times
Galaxy S7 : 17818m mAh / 3000 mAh = 5.9 times
iPhone 6S : 17818m mAh / 1715 mAh = 10.3 times
Iphone 6s Plus: 17818m mAh / 2750 mAh = 6.4 times
Quick Charge : The Harvey Dent of PowerBanks
Here's something that no manufacturer will ever tell you explicitly, nor have I seen many reviewers touch upon this subject across different brands. While having a Quick Charge Port is undoubtedly convenient to juice up your phone quickly on the go - It comes at a big cost . As you can see from the formula in the above section the actual usable capacity of a Powerbank is INVERSELY proportional to its output voltage. The Quick charge technology is able to charge devices quickly by applying a higher power using higher output voltages. Typically at 9 Volts.
Thus the usable capacity of the Powerbank using Quick Charge Port Operating at 9V becomes :
( 98989.8 mWh / 9 Volts ) * 0.9 Efficiency = 9898 mAh
Number of Quick Charge Cycles you can get :
Galaxy S6 : 9898 mAh / 2550 mAh = 3.8 Times
Galaxy S7 : 9898 mAh / 3000 mAh = 3.2 Times
That's almost half of what you can get using the Standard AiPower Smart port! It doesn't look so impressive now right? Yeah. Again this is nothing against this Powerbank in particular & its just how the Li-Ion & Quick Charge Technology works. My advice is if you have the time (like camping etc.) and really dont need Quick Charge - Use the standard 5v/2.4 A AiPower Port or turn off the Quick charge setting temporarily from your phone
Quick Charge Test
So if you do decide to use Quick Charge from the Powerbank , you can be assured that it does a great job at it & supplies the same power as my OEM Samsung Adaptive Fast Charger (See Pics) :
Samsung OEM Fast Charger Applied Power = 14.22 Watts
Aukey 30000 mAh QC Port Applied Power = 14.54 Watts
AiPower (Smart) Port Test
For this test I connected a a wide variety of devices to determine if the AiPower port detected the devices connected to it accurately and supplied the rated current for it. My testing showed that the Hub supplied near max current to them at a stable 5V. Measurements were taken using a Drok USB Ammeter. I also noticed that the charger stopped charging and applied only a minimal 'Trickle charge' once a device reached 100% to avoid overcharging/damaging your battery
iPhone 5s : Supplied Current = 0.97 A , Manufacturer Rated = 1 A
Galaxy S6 Edge : Supplied Current = 1.73 A , Manufacturer Rated = 1.7 A
Anker Powerbank : Supplied Current = 2.09A , Manufacturer Rated = 2 A
PowerBank Charging Times
Due to its massive capacity , the charging time required to fully juice up this powerbank becomes important . And I am really happy to see that Aukey as rated this powerbanks's max. charging input at 2.4A ( see my charging pic) . This makes it one of the faster charging powerbanks out there . Only the 3A USB-C input powerbanks are faster than this one which are pretty rare.
- Charging the powerbank at 2.4A takes about 12 Hours from 0% to 100%
- An important note to iOS users - While the inclusion of a Lightning charging port is a big convenience - Please dont use the original charger that came with your iPhones to charge this powerbank , because the Original Iphone Charger is only rated for a max current of 1A . Which means you are looking at double the charge times around 24 Hours to fully charge the powerbank!
- I received a promotional sample for my review, as you can see the views reflected are highly objective and my own
- I used this PowerBank extensively and tested it for a good amount of time before sharing this review with you to give an accurate picture
An added benefit of this device is the Quick Charge port. This is especially useful when you have a newer Android device (those are the devices that are most likely compatible with Quick Charge 3.0). This port functions like the other normal port if you do not have a Quick Charge 3.0 compatible device.
This external battery is pretty affordable, in my opinion. The build quality is great and it has a simple, sleek design.
One design flaw that I have noticed is the charge indicator light. The power button turns white when the battery is charged in the 70%-100% range. This means that you could think your battery is fully charged when you see the white light but it may actually only be at 70%. At 30000mAh, the difference between 70% charged and 100% charged won't affect most instances of use, but it's worth noting the design flaw.
If I need to charge this battery, I usually do so with an iPad charger block because it charges faster than a phone charge block. It's probably best to leave it on the charger during the day while you're out, so you can come back to a fully-charged external battery.
I spent 10 days traveling to Europe recently and only charged this external battery once (just because I didn't want to risk running out of juice on the way back to the States).
I would highly recommend this external battery.
Although it doesn't show exact percentage, the color-coded power light is helpful for determining remaining charge.
The fast charge absolutely works as stated, though I find my electronics last longer through the day if I use the "smart charge" (read lower amperage) port.
Of note, this battery pack is technically illegal to take on planes due to TSA regulations, but none have checked the watt-hours and size of the battery, so just carry on and you'll be fine.
The flashlight is neat but a little gimmicky as it takes five seconds of holding the button before it turns on, but not the reason I bought the battery anyway.
I've dropped this from five feet multiple times on rocky soil, and haven't had issues, but wouldn't recommend pushing your luck.
I charge this with a solar charger as I'm in the military. It won't make it to full charge from dead in a day of good sunlight, but it'll more than recoup whatever you spent on charging your phone. Wall charging will be faster.
