The build is sturdy and feels like premium materials. Although the matte finish is gorgeous looking, its a fingerprint magnet! Thankfully they include an perforated travel pouch that keeps the Anker safe and fingerprint free. And yes you can see the illuminated LED dial through the pouch quite clearly.
The "SMART" USB feature charges up my phone super fast! with (5V / 2.4A max) of charging power
Ankers LED light ring is a genius touch. The indicators for "battery percentage" and "charging" are simple and straightforward which can easily be activated by a little shake... yes I said "shake". there are no physical buttons on this device but a simple motion sensor that will activate the LED and the implied function.
Overall i'm quite happy with the purchase and the product. its sleek, modern and will power all the USB devices.
It has lots of capacity for charging phones and tablets. I used it to go cross country with my Galaxy S3 and Nexus 7. It charged both as fast as a wall adapter would and had no problem keeping both charged for my airport layovers and delays. No more hunting around in the airport for a wall socket.
I've used it a couple times since I got it 3 weeks ago and I was very happy to have it around. My phone's battery is on its way out, so this helps when I'm away from a plug for too long, but it should also come in handy when travelling. Essentially, it works exactly as advertised. Just remember that there is some energy loss when going from the power bank to your device, so the 12,000 mAh ends up being about 10,000 mAh, which is still a ton.
CONS: It only comes with a cable (no wall socket power adapter), but you probably already have one with your phone/tablet. It comes with a VERY tight fitting protective cloth case and it is somewhat difficult to use, however you can just leave it in the cloth case permanently to protect it and you can still see the power LED through the cloth case. Finally, the USB sockets/cable fit together very tightly as well and it takes a little force to plug/unplug, but this may also be a good thing since a tight connection would hold up better if it were bouncing round in a bag. All in all, the cons really aren't that bad.
I'm completely thrilled by this level of support. To the Anker staff members involved, I tip my hat to you all!
I wholeheartedly recommend Anker and their products.
Again, you have gratitude Anker.

The built quality is nice, it charges well and is about the size of an external hard drive, so it fits easily in a pocket in my backpack. Anker deserves a 5 star rating for this product. They seem to have created a superior product for less money than some of the competing products I looked at.
After the first initial charge, this power bank works wonderfully in charging my phone and my tablet. It takes overnight to charge but then it will be able to charge my phone to full multiple times and my Samsung tablet once. So the battery capacity is very good. However, after the initial charge, it will not recharge anymore, I have plugged it in overnight multiple times and it was still not charging. I played with the cable and found out what the problem was: loose connection at the input port. I had to press downwards in order for the power bank to start charging and as soon as I let go, the light will turn off (which indicates that it is not charging). So I am unable to recharge the power bank as I can't constantly push the cable down overnight to let it recharge all the way. It's too bad since I really liked this powerbank for its capacity and sleek design but this problem had made it unusable. Very disappointing since now I am stuck with a broken power bank during my holiday. What a waste of money.
