Looks Good - Works Bad!!
on November 5, 2013
First the good things - Product looks nice, the blue LCD is cool.
I haven't done any controlled testing, but I don't think this one is 12000 mAh. The other reviewer said that it has 4 batteries of 2600 mAh each, so a total of 10,400 mAh. That number seems closer to reality.
The charger is very slow to charge. I charge my Sony Xperia when it comes below 30%, and the wall charger with 1A output charges it in 2 hours. But this battery pack takes almost 3 hours to do the same.
It has NO FLOW-THRU charging, meaning it cannot charge other devices while it itself is charging. This is a big flaw for me. One of the other reviewers posted that it has flow-thru charging as along as the charge is not near zero. A load of hum-bug I tried at different charge levels, even 99% - it won't start charging the connected device until it is fully charged.
It is picky about what is charges. It charges Sony Xperia phone, LG Phone and MP3 player. It will not charge a Nook HD and a BlackBerry. I don't have any apple devices, but I think it will have trouble charging any device that is picky about its power source.
DO NOT BELIEVE the glowing positive reviews. They are from professional reviewers who got the product free in return for posting positive reviews.
Lastly - there is NO CUSTOMER SERVICE. NO PHONE NUMBER, NO WEBSITE... NOTHING. Just an gmail address. Thankfully Amazon will take it back, but I am leaving on a month long international trip this week and I have to deal with this issue at the last minute.
Save yourself the trouble and go with a proven brand like Anker or NewTrent that have a decent website and a responsive customer service.
