A particularly small battery to fit into any pocket but large enough to quickly charge a device! Indeed, the burden of 2.1 mAh allows a fast charge, the same as a power connection of your PDA, GPS, or tablets. It also will run almost all the devices on USB charging. Tested with an I-Phone 4S, camera GO PRO, tablet Galaxy TAB 3, a HUB and my Wifi GPS: it is perfectly filled office. For a capacity of 3000mAH is is not so bad, all the more what is only the loading mode for your device by a charging mode Smart said.
