Landrover Posted May 25, 2022 Share Posted May 25, 2022 My GMC tow vehicle has a 400 watt plug in the rear corner of the bed. I cant see much use for it except for plugging in a portable fridge cooler. I’m wondering, if a solar panel can put out 1-2- 3 400watts with a charge controller can this 400watt plug be used in connection with a solar port connection and a charge controller as how a portable solar panel works? Of course the truck would have to be on and idling for the plug to work. Just thought this would be another possibility for battery charging. 1 Grant 2022 GMC Denali 2500 HD 2019 Elite 11😎 Link to comment Share on other sites More sharing options...
