The Dual-Slot Charger for SJ9/SJ10 Series Batteries from SJCAM allows you to simultaneously charge two SJCAM SJ9 or SJ10 lithium-ion battery packs. It can power by either a micro-USB or mini-USB port, and it includes a micro-USB cable for powering the device from virtually any USB power source. A red LED indicates when the battery is charging, and a green LED when your battery is charged.
