Does have a good charge to it when I first bought it. After 8 months it is starting to bulge the metal case that it is in. Doesn't hold a charge for long.

Sleek.

Easy to use, purchased this for travel and is so handy! It's a must have

- 10,000 mAh capacity seems to be accurate (tested with htc m8: did 2 full charges and the battery indicator says 50%. M8 battery is rated @ 2600 mAh) - Very sexy looking compared to other battery packs that has this capacity - Perfect size to be in my pant pockets - 2 Ports

- I did experience what other reviewers are saying about reviving it with a charge, but it only happened to me once out of 2 months. Happened to me with a 75% charge

I think this is a bargain price when on sale...

Holds long charge and can charge phone several times easily if it does not fail.

It often fails during or between charges with plenty of juice still in it with no way to reset it other than to reconnect it back to the computer to wake something up. I charge iPhones but need to carry a Samsung charger to do this with my laptop while away from home.

Buy the ADATA ones instead. They have the same capacity and work better.

large capacity

same issue, only charge for about an hour and stopped. have to plug it back to ac to make the unit switch mode internally. then I can plug my phone to charge again for about an hour. looks like there is some internal issue with this unit.

- Looks great - Decent capacity

- Doesn't hold a charge. - Won't re-charge itself when plugged into AC. - It will intermittently stop charging devices after an hour or so and then completely stop working requiring you to plug it back into AC.

I bought this in Calgary before going on a trip to New Zealand about a month ago, it's extremely problematic. 90% of the time it won't charge devices and when I have my phone plugged into it it stops charging it after an hour or so even though the battery is not depleted. I've opened a support case with Antec but apparently their support with these products is non-existent with many complaints by customers. If I were in Calgary I would return it for a refund :(

- The capacity is big.

- When the battery bank is completely drained, it takes about 18 hours to re-charge. - My LG G4 battery is 3000mAh, but this battery bank can only charge it about 2.7 times. I was expecting 3.3 times... - Also, the charging time is slow.

It is okay.

Charges my iPhone 6 3+ times on a single charge, plus Ive charged my iPad mini, iPad 4, and my iPhone 6 twice without any issue.

It takes a while to charge when completely drained, however the number of times I can charge my phone and other devices on a single charge, it makes it worth the wait.

Ive had this item since Dec 2014 and this battery pack is still going strong. Aside from the time it takes to charge when drained completely its the best battery pack Ive ever owned!! Must have Item for ANYONE looking for a battery pack while you travel, or just everyday use.
