Although for charging your battery Go pro who semboîte as it should, but the USB port does not work for the remote control .... normal there are only 0.55 volt output on the USB against 4.2 volt battery for the harbor! !!! Avoid it if we account for the remote control!
A second charger was sent to me for free, by the sympathetic and responsive vendor ..... but the same conclusion! I guess the manufacturer (CPP) has forgotten some connections inside !! So if you comtpez use the USB port, go your way!
