Why is my Burton lunch box not working on AC Current?

It sounds like it would be the inverter is too weak, probably need to just read carefully what the requirements are to run the fridge and make sure the next inverter you get has that output. You may also check to see if they have a website that offers inverters specifically for their appliances.

 

You need to use an AC to DC adapter designed for cig. plug applications

 

They have Crockpots at Wally World for $9.99

 

I could see where that would be useful for a cooler. I've had to throw food away before after a break down landed me in a hotel for a few days and no way to plug in my cooler.

But as for the Burton stove...dude, those things are throw away junk. I've never had one of those things last more than six months. At some point between month 1 and 6, it stops working. You tear it apart, and the wiring inside is burnt and brittle, so you rewire it and get another week out of it. Pretty soon you can't rewire it any more so you toss it out and buy a new one. And the cycle starts over again...

I did that until about 5 years ago, when I bought a regular 110 volt crock pot for ten bucks at Wal-mart. I plug it into a $29 400 watt inverter. I'm still using the same five year old crockpot, and inverter for that matter. You can cook exactly the same stuff that the Burton stove does. And, the ceramic pot is a LOT easier to clean, especially if you spray some Pam on it.
