The NP-F980 7.4V 6600mAh Li-Ion Battery from IndiPROfeatures two USB ports built-in, one a USB Type-A output for charging mobile devices, and the other a micro-USB power input. The power input allows you to connect the battery directly to a USB power source to recharge it, so you won't need a battery plate or any dedicated charger, although most L-series chargers can be used, including those from IndiPRO. The battery also offers a 4-LED gauge on top that confirms the remaining battery capacity at the press of a check button.
