Buyer Beware

Review By: L. E. Fox, on March 14, 2010

This is a terrible product. First (and least problematic), it's heavy and bulky. Imagine your iphone twice as big and heavy as it is alone. Second, it added only an hour or two to the available power on my iphone. Third (and most serious), after only a few weeks charging my iphone through this device and then carrying it with it, my (relatively new) iphone won't keep a charge for more than about an hour of use. I'm going to try to return this, but I would never again buy this product. Be careful!

don't buy it! Just worked for less than two months

Review By: Yue Wu, on February 25, 2010

I bought two for me and my wife because both of us have iPhone 3G and the battery won't last long if we keep watching youtube. So far one of these two iPower protective cases already stopped working, and I noticed that for the other working one the standby time after using for one month is also getting shorter and shorter. This is a terrible product and don't waste your time and money on this crap!

Good on iPod Touch, Bad on iPhone

Review By: Canh Nguyen, on February 10, 2010

The Good: The battery extends the battery of my my iPod Touch for at least a couple of days. Normally I need to recharge it at least once day. It is a little bulky though. The Bad: I also bought the battery for my wife for her iPhone. For some reason it keep on have a clicking/charging sound every 5-10 seconds. I tried adjusting it, tightening it, but it did not work. I gave up and gave it to my niece the extended battery,. Overall, I would recommend it for the iPod Touch, but not the iPhone.

Works great

I bought two of these for Christmas gifts and both recipients are very happy with them. I have an InCase Power SLider and wish I would have bought one of these instead, cheaper and works better.
