Cigarette Lighter Power Supply

120W is suppose to be fuse with a 10 Amps, so you're OK if you don't want to charge over 10 Amps

Usually the car guys go with a safety factor of some kind, so I'd guess its really good for like 150watts and they've fused it at 10a to limit it to 120watts.

That would still power a lot of stuff, nice accessory!! Def run a charger.

if the receptacle is rated for 10 amps you can probubly charge @ 8 amps at the charger
