12v issues

Replaced my 10 year old Coleman cooler with a new one. Old one just got to beat up. The new cooler burned out the same outlet I have always used. Didn't blow the fuse but actually burned out the outlet. The plug got extremely hot to the touch. Does this new cooler pull to much juice? Is there anything I can do to fix this?

Also, I have an APU with a power inverter under the bunk. Would a 12v to 120v converter be a better option for running this cooler?

 

Thanks, yes you are probably right. I notice some 12v outlets are deep and some are shallow. The Coleman has a deep plug and the outlet is shallow. Wish there was a uniform size. Wondering if the outlet depth corresponds with a rating?

 

Well problem solved. I ended up cutting the 12v plug off the new cooler and replacing it with an old 1 into 2 12v adapter I had laying around. Much better quality and it's been running 20 hours now.

It's as cool as ice where the old one melted itself. Mind boggling that of all the places they could cheap out on, they choose a place that renders the product useless!
