Simultaneously charge two GoPro AHDBT-401 type batteries from USB power sources with the Watson Mini Duo Charger for GoPro HERO4 Batteries.
The Mini Duo features dual battery bays and allows you to charge a single battery or two at a time. A separate LED indicator for each bay displays charge status of each battery at all times. The charger offers both Mini-USB and Micro-USB power ports, allowing you to connect to a USB source with cables matching either port. A Mini-USB cable is already included, so you have everything you need to connect to a USB adapter, your computer's USB port, or other USB power source.
