I got this for my HTC EVO 4G because the battery life isn't all that great. If your always on the go then this will be very useful in charging and keeping your smartphone or phones/ipod charged if your not around an outlets. It said it can give you 15hrs of battery life but I've only needed for a few hours to recharge my HTC EVO
A:AnswerYou can charge the PowerPort Duo with the included Mini USB to USB cable. Just plug the Mini USB into the case, and the other end into your computer’s USB port, a USB wall plug style adapter, or a USB DC car adapter.
The LED status indicators show the current charging status of the PowerPort Duo. The LEDs will blink and become steady as it charges, from left to right the 1st LED, 2nd LED, and finally the 3rd LED. Once the 3rd LED has become steady, the charging process has finished.
If you have any further questions, please let us know.
