12 V Plug in Bed
Hi,
I've installed a 12 V outlet in the bed of my 2018 F150 and ran 10 G wire directly to the battery with inline 30 A fuse right off the battery lead. Grounded from 12V plug near hitch on frame. Outlet works for cell phone charger and other smaller devices. I installed the outlet to power our 12V cooler in the bed. I'm at a loss as to why it isn't working for the cooler or air pump, etc. The light on the plug turns on for the cooler, but as soon as i connect to the cooler, it goes out and does not turn on. I've tried various gauge wires and still nothing. Any help would be much appreciated! Could it be the Amazon outlet i used (not being able to handle the Amp of cooler?). This is outlet I used:
In reviews others have said they used as a 12 V outlet to power coolers. GRRRRR.
Thanks

I have a feeling your battery might need to be replaced.
Personally, I recommend running a secondary battery in parallel. I do this on my truck to run a 3k inverter so I have 120v all over the place on my truck. I also running charging circuits and a 240v step up converter for small Euro inductive appliances that I can switch between 50/60 Hz. My truck has 4x 12v outlets, and 6x 120v outlets and 2x 240v outlets.
If I wanted to spend the time and money, I would run a single 3-phase circuit so I can run small 3-phase motors. LOL
