Fridge and microwave install

The inverter will definitely run a fridge. The smallest microwaves are 500w I believe, both under $100 each. I noticed a while back, seems a lot of company trucks have a 1800w inverter. Little fridge draws hardly anything. One way to find out.

 

This little guy has been great...runs off 12v.

I don't think I need to tell you which ones I bought.

And they worked just fine; lasted 1-3 years (could still be working... went with the truck).

However, I will second a Koolatron cooler. We've had one for ~20 years, still works, but it has only ever been used for occasional road trips, not constantly.
