2018 Silverado cigarette lighter and fuses

Recommended Posts

I have a 2018 Chevy Silverado Texas edition. My question involves my trucks 120VAC outlet and the many 12VDC outlets.


I want to power a device that requires 300 watts from my truck. It’s a powerful laptop charger basically.


the 120V outlet my truck comes with is a pathetic 150 watts. Can anything be done about that?


Also, I can use a 300 watt AC/DC inverter instead. The inverter works fine but that puts 25 amps through my cigarette lighter which blows the 15 amp fuse.


can I swap the fuse for a 30amp? I know of fords with 30 amp fuses. Seems like my truck is electrically very wimpy. Surely the outlet and cable is rated for 30+ amps so I should be fine.... right?
