When you're nowhere near a power source and your phone battery is running down, the only thing you can do is shut it down, right? Wrong! You can continue to use your phone when you have one of these Backup Battery Packs from Monoprice!
This battery pack has a micro USB B male plug on the top, allowing it to be inserted into the charging port on the bottom of most phones. The battery pack features a 2800mAh charge capacity and a 5 VDC output at 800mA.
The battery measures 3.5" x 2.4" x 0.6" and weighs only 3 oz. It can be used to charge your phone's battery or to use the phone with an almost depleted battery charge. It is recharged in about 6-8 hours using a standard USB charging source.
