Takes FOREVER to charge. (10+ hours)
A note about "capacities"

Great product, but overstates it's useful capacity a bit.

There are 6, 18650 li-ion batteries in here, which are 2250-2500mah @ 3.7v. That means this is at best, 15000mah @3.7v. THEN, it goes to a step-up converter to push out 5v over USB, which will be about 90-93% efficient. So we're at 14000mah @3.7v Then, your phone has a charging circuit which takes 5v and puts it down to 4.2v for charging the battery, which is about 93% efficient... so we're at 13,000mah @3.7v So really, you could expect 4 full charges out of this for most phones. Still VERY useful, but nowhere near 20,000mah.

Its kind of like back in the day when Horsepower was advertised at the Crank, instead of the wheel. Who cares what Crank HP is, you just want to know how much you can actually USE. So the answer is more like 13,000mah. An Average phone has a 3000-3200mah battery.

Just keeps on going!

I bought this to power a raspberry pi and screen. I haven't run it to death yet, but it has no problem running both continuously for 8 hours straight with still some juice to go (impressive in my eyes).

Having the dual USB outlets is a must for me. It allows one to go to my screen and the other to go to the raspberry pi. It is stable and the pi never stuttered once.

I have not use the lightning input, only micro sd. No issues charging it, or it turning on.

The only thing I wish it had was an "always-on" option, but that is only minor. Some of the other battery packs I have are always on, regardless of the power button. This means as soon as you plug devices in, they start charging/powering on. With this pack, you need to hit the power button. Not a big deal, but I rather it just be "always-on". 5 star regardless of this due to me buying it knowing this.

First impressions.

I drained the battery first and charged it up.
Capacity on first charge is 17090mAh.
Second charge is 17055mAh.

The battery will only charge at a MAX 2.1A. Aukey's 12000mAh battery charged at 3.4A which was very surprising despite it's 2A charge specs.

This battery is HUGE. It's the size of your entire hand or a Samsung Note 3. However the weight is not bad at only around 250 grams.

So far not bad. I will update with more capacity as I charge and discharge it. Not quite 20000mAh, but I hey, what can you do.

I’ve been quite hesitant when it comes to getting a power bank, many people say you do not receive the true power and get scammed very often. I finally took the risk and got an aukey power bank, and I can say I’m pleasantly surprised to how well it works.

PROS
- Very well built, the power bank comes with everything you need and seems like a quality product
- The power is exactly what it claims to be, I can easily charge my phone, Bluetooth speaker, tablet, etc. multiple times without having to recharge the power bank
- Aukey products are backed with their warranties and always yield good results in my experiences

CONS
- Since the power bank is so large it is quite heavy and inconvenient to carry around in your hand
- To recharge the power bank takes around 10 hours, so you need to charge it in advance if you want it’s full capacity

I would definitely recommend this product although it is heavy and quite bulky, you can’t go wrong with having the extra power. I can go for days without needing to be near an outlet thanks to this handy product!

This little charger packs a lot of power and has a very sturdy construction so it can take some abuse on the hiking trails. It does have some weight to it but its a fair trade off for the amount of power it can store.
It does require a very long recharge time though, at least 14 hours when completely dead. When I inquired at Aukey about the long recharge time
I was told to use only very short USB cables and to isolate the charger on one circuit (don't charge any other devices at the same time) to speed up the recharge time.
If you can live with the long recharge time then you'll be satisfied with this device, easily can charge ipad, iphone, android phone, as well as 5 volt camera battery (using usb battery charger) on same charge.

I've become a big fan of Aukey products since I first bought one a couple of years ago. The products all feel like quality and have never let me down. I bought this product to upgrade from the 12000 mAh Aukey battery that I've been using. Although this one is larger and heavier (which is no surprise, given the much larger capacity), it's also even more clever. I like that you can use a Lighting cable to charge it as well as a Micro USB cable. With this in my laptop bag, I never have to worry about running out of juice on my iPhone or iPad.

Great item to have. Holds more than 7 charges for my Galaxy S5(s). I purchased two of these in conjunction with the Aukey 20W solar panel as as means to keep devices powered during a camping trip this summer. Charge these during the day to charge my phones at night! I will follow-up after that trip, hope all goes as planned.
