12v outlet/3-in-1 adapter Question

God don't you just love it, a meltdown in the cab because ... wrong fuses

Put ice in the cooler, charge your laptop and phone while driving for a couple hours - shut the laptop down and disconnect the phone when you don't need it - and plug in the cooler.

Is there binders for a CB with that truck?

 

You should not put higher rated fuses in electronics. They are engineered for a certain Amp. Change the fuse to a higher rated fuse only will cause the electronics to blow instead of the fuse. I run the 4/1 in my car with no issues. The cooler is drawing the most current. Put the original fuse back into the 3/1 and find another outlet for the cooler. If it is a Coleman it should have come with a DC/AC adapter. Plug it into that and then into your inverter.

 

I did too, but I ended up putting ice in the stupid thing until I straightened up the electrical issues but then I decided to get a real fridge and put money into an Engels.

 

The 3/1 and 4/1 were made for the smaller electronics not a cooler. Most cabs come with a DC outlet in the bottom cabinet for a cooler or Ref. The upper shelf has one for a TV and usually a few in the bunk area.

I got my Coleman at WalMart. It was the same price with the adapter.

 

Sorry if I missed out on what you had. So when driving why not plug the cooler in the one in back? Your phone should have a DC charger you can use for the front.

You are limited in power out.

Not much can be done for your situation.
