I have two DJI Mavic Pro's and needed to charge my four Intelligent Flight Batteries and both Remote Controllers. So, I connected my four batteries to the DJI Charging Hub and both DJI Remote Controllers to the USB ports on my DJI Charger. All four batteries charged completely but the Remote Controllers did not charge. [size=14.6667px]When I charged the batteries separately they charged successfully. The DJI Charger has two USB ports so why wouldn't my Remote Controllers charge being connected at the same time?
