Power Inverter For My Truck Doesnt Give Power To My Electronics

Check the outlet. Does it have a reset button in the center of it. Some do and some don’t. What brand is it?

There may be a 250 amp fuse in a black rubber and casing in your battery compartment..

Your total amperage far exceeds with that inverter can supply.

Don’t ever run a microwave or toaster oven without either the engine or the APU being on.

APU:

Auxiliary Power Unit

On tractor trailers, and APU is a small diesel engine that powers a heat and air conditioning unit while charging the truck's main batteries at the same time. This allows the driver to remain comfortable in the cab and have access to electric power without running the main truck engine.

Having an APU helps save money in fuel costs and saves wear and tear on the main engine, though they tend to be expensive to install and maintain. Therefore only a very small percentage of the trucks on the road today come equipped with an APU.

I had the truck on when I tried it. Just to be safe lol .but I looked and didnt find any fuse by the battery.

Cobra’s aren’t bad. I have one. It has done me right. It replaced an expensive one from thermoking that only lasted 20 months. It sounds like something inside probably overloaded and went bad

The fuse will be about 1“ x 2 1/2“ of silver and black kind of a flat piece of silver metal with black in the center about a centimeter thick. If you have one. Might look like this :
