Dual Input sets this device apart from others
Reviewed in the United States on July 15, 2016
After purchasing several power banks over the last year or so this is the first time I've bought anything other than Anker, and for good reason: this is the first device that I've discovered that allows you to charge with more than one input. Many power banks (especially the larger ones) have multiple outputs, technology to detect proper voltage/current, and QC 2.0/3.0 capabilities but this is the first that allows you to recharge it with more than one input.Capacity (5/5): The capacity of this "Monster" is more than enough for your casual user if you are going on a trip/camping/hiking because the 20,000 mAh will keeps your devices with plenty of juice. I opted for this model due to the price point ($32.99) as opposed to paying close to $50 for the 26,000 mAh (which also boasts dual input charging).Size (4/5): While there are power banks that are smaller than this one that have similar capacity (The Anker Powercore 20000 comes to mind) I did not find the size to be too large to the point of being cumbersome. To be honest if you're looking for something with this capacity or greater you can't expect to buy something that will easily fit in a pocket or small purse. This fits great in backpacks or other larger bags (I've kept it in my messenger bag and it fits nicely without occupying too much space.Charging Speed (Input) (4.5/5): EasyAcc advertises that this device is capable of charging up to 4 amps at 5 VDC if you use both ports (and an adapter capable of handling that voltage and amperage). According to the product description you can charge this device in about 6 hours. If you have a basic knowledge of voltage and current 4 amps at 5 VDC should actually charge the device in around 5 hours. I used a USB Drok Multimeter to measure the current and voltage to discover that the device didn't quite reach those values (pretty close though). With these measurements (5.25 VDC and 1.70 amps) I discovered that the claim of 6 hours hours was pretty accurate (1.70*2=3.40amps; 20,000 mAh/3400~5.88 hours). This would have been a 5/5 for me if the device actually pulled the full 4 amps (maybe others have had better results) but in that case they would be able to claim that it could fully charge in only 5 hours. Not a major gripe when you consider most power banks of this capacity (5 VDC at 2 amps) would easily take around 10 hours to fully charge. This still means that you are saving 4 hours just by adding the extra input.Output (5/5): While I have not yet had the change to use all four ports simultaneously to test the claim that it charge 4 devices at once with a total amperage of 4.8 it seemed to work well for any device I plugged in. If I plugged and iPhone in I measured about 1 amp, an iPad came in at 2 amps, and my Note 4 only measured around 1.30 amps. It doesn't offer anything fancier than EasyAcc's Smart Output (sorry no Quick Charge/Fast Charge capabilities) but it works well enough to charge multiple devices and still have plenty of juice to spare.Extras: The built in flashlight is a nice addition to this product. It's not something that was a factor in my decision to purchase this however. This power bank is big enough that you could probably run this thing for hours (or days maybe) before it needs to be recharged. I'm assuming it doesn't add much in terms of size or weight (otherwise I probably would suggest removing it in the interest of making it more compact/portable). I would rather have this device smaller/lighter as opposed to having a flashlight (if it adds significant weight/size) that I'd rarely use.Conclusion: This device stands out among all other battery banks I own simply because it allows you to significantly reduce the amount of time required to charge it. It doesn't offer much else to stand out but when you consider the fact that nobody seems to be implementing Quick Charge capabilities to recharge these power banks (The Anker PowerCore+ 10050 has this feature but it's only 10,000 mAh and that's the only device that I've seen with QC technology). My recent purchase of the Anker Powercore 20000 has the ability to charge devices at QC 3.0 speeds but you still only charge it at 5 VDC and 2 amps which will take about 10 hours. As it stands this device is innovative in its approach to decreasing the amount of time we need to wait for a device of this size to be charged.One of these days I may have to purchase the 26,000 mAh version since that one should charge in less than 8 hours.

13709mAh * 5v = 68545 mW
68545mW / 3.7v = 18525 mAh at 3.7v
18525 / 0.90 = 20,584 mAh actual battery pack capacity at 3.7v after factoring in 10% loss for the regulator
I tested this with both real devices and variable load modules. My phone, PS Vita, and an old MP3 player seemed to top out at draining from this thing at about 1 A. I'm guessing that must have been a limitation of the devices that I attached to the power bank because I also tried the variable load module, and was able to pull 2.8 A off it for some time, which is above the 2.4 A stated limit. I did this for about 5 minutes and noticed the device did get warm, but not dangerously so. I conducted the rest of my tests by setting the variable load to 1 A and 2 A. It seemed to hold up slightly better at 1 A than 2 A, as expected. It was cool while at the lower drain rate and I seemed to get about 2000 mA more out of the pack at 1 A than at 2 A. Not earth shattering, but something to keep in mind.
The pack itself is relatively heavy, which is good for something like this. Light means it's light on lithium, and a 20,000 mAh pack shouldn't be. The LED lamp on it is a bonus and functions well enough to get around a dark room, and will stay on for a very long time if that's all you're using the pack for. I left it on for 5 hours, and it didn't go down 1 notch (out of 5) during that time.
The dual inputs for faster charging is actually an asset here. I had it hooked up to two 2.4 A ports on a USB charger, and it actually charged in not quite half the time. 6 hours compared to 10. Still, a welcome improvement with a large pack like this. If there are concerns about charging this too fast and reducing cell life, I wouldn't worry about that. There must be at least 8 cells in this, which would put the per-cell capacity at around 2500 mAh. A 1C (2.5 A here) charge rate would be a quick charge and 0.5C (1.25 A here) would be a standard charge. Having both inputs active at full capacity would yield a max charge input of 4 A, spread over 8 cells is about 0.5 A, or about 0.20 C, so it's not a dangerous or damaging charge rate.
Overall, I would say that this was a good buy. I purchased two of them, and I'm adding it to my "save for later" list in case I need a third.
EDIT: July 3, 2017
NOTE: Opening a device like this should only be performed by a professional, and using appropriate tools and safety precautions. Shorting a power pack like this can cause a fire, so don't do this at home unless you know what you're doing. Additionally, keep in mind that doing so voids the warranty. I've also been asked by the manufacturer to censor the model number of the cells to protect their intellectual property. I have circled another part that is of interest, the rating of the cell from the manufacturer, so these are genuine cells.
I performed an additional drain test to see how far this bank can be pushed. I don't recommend pushing it beyond the rated 2.4A @5v, but my particular unit was able to keep its voltage statistically stable at 2.6A out of one port.
After performing a teardown of the device, I found that my math was right. Inside are 8x 2600 mAh 3.7v cells, for a total of 20,800 mAh. Looks like we get what we're paying for. That being said, at a purchase price of $30, that's less than $4 per cell if you want to scrap this and use the cells for projects. Good value either way!
Finally, one that lives up to its claim.

I'll start with the meat. My trials tested this and ran at an average of 13,709 mAh, which sounds low, but it's actually right on the mark to meet the claim of 20,000 mAh. Here's how. That's 13,709 mAh that I got out of the pack at 5v, not how much went into charging it, so this is real usable capacity. We can work backwards to find what's in the pack.
