Welcome to the forums.

The reason the plug melted is that there is a poor connection between the lighter plug and the lighter socket. The cooler draws some decent current which creates heat at the contact location.

That lighter plug is a very light duty one. Try to find something a little heavier duty.
There is polarity to the wiring. One conductor will have ridges on the outside of the jacket. Make sure that wire gets reconnected to the same contact it was on originally (center pin or shell)
Most lighter plugs are attached with a soldering iron.

You may have to clean or replace the lighter socket if it's corroded or rusty.

Look around for Safco lighter plugs. They can be installed without a soldering iron and they are good plugs. The last one from amazon.... buy the entire cord and chuck the cord and keep the plug. The plug can be removed and reinstalled.
