does anyone know why the inverter plug goes on and off when you put it in gear? i have a fast drone battery charger and tried to use the inverter to charge my drone batteries and the inverter is basically useless as far as i can tell,,,, what is used for it you can't use it while you are driving, which seems to be the case.
also,,my switch says 100w and also 400w,,, how do you know how many watts it is putting out?
