i have a multi charger for my MPP that charges 3 batteries at the same time, plus two standard USB outlets, i charge my controller using the original lead that came with the drone , it goes from one of the USB plugs in the charger to the side port on the controller, and i charge 3 batts +controller at the same time with no issues
Both Rick of Drone Valley and I came to the same error regarding the AC charger and the RC. Both of us missed that the charger has a built-in cable specifically for the RC tucked away on the side of the charger. We both found it silly to have to use the USB-C cable with the micro adapter connected to the charger's USB port.
I'm not sure how well that charger would fair charging the AC battery, remote and a mobile device at the same time. It's only a 60W charger.
