My V90 -17 takes about 17A when ignition on and lights off. It took about 10min for the voltage to drop below 12V when ignition on. 10A didn't help very much in my case but 25A charger can keep voltage high enough. I'd recommend powerfull charger or power supply. It is so much easier to work when you just plug your power supply and you don't have to hurry or keep watching the voltage all the time.
