All you really need is the 12vdc power for the control board.
So, get a juice friendly acquaintance to:
A - Locate a 12VDC wall wort.
B - Attach it to the DC supply terminals of the unit.
There is usually a duplex receptacle behind the unit that the wall wort (plug in power supply) can use.

Wall warts usually produce really crappy unfiltered DC. That fridge also requires 400 mA of current at 12VDC. Make sure the wall wart will supply at least that. The one I have to charge my ham radio handheld puts out 13.2 V at only 70 mA
Wall warts have changed quite a bit in the past several years due to new efficiency requirements; most new ones are now little switching power supplies, and produce quite well regulated and comparatively clean power. At most a small filter capacitor and maybe an RF choke would be needed. Of course, that only works if you camp where electricity is available in the first place.
