Get power on the move with the Discovery charger. The unit uses a 3500mAh lithium polymer battery to recharge an iPhone twice, standard cell phones 2-4 times, or give iPods and MP3 players up to 120 hours additional runtime. The USB port has self-sensing technology, allowing it to optimize charging parameters for iPhones and other smartphones.
LED lights show the unit's power level, and warn when it needs to be recharged. The Powermonkey Discovery can be recharged via a computer USB port or USB socket charger.
