2018 Silverado cigarette lighter and fuses

[Aaronkoe]

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?

To run the size inverter you want I think it would be better to run a designated line with the proper size breaker fuse that you need.

You'll also need a heavy duty alternator.  Maybe like what they provide on the police package Tahoes?  If they still do that..
