I found one at a junk store for $20, They use the ancient system of "Adsorption" refrigeration. It is a closed system of ammonia, water and hydrogen. that cools without a motor. It is the same type as the old Servel gas fridges except instead of using heat from burning gas it uses a electrical heating element. It's maximum power consumption is 60w. It cools better than a Peltier yet it is even quieter.

The mini bar fridges were the kind that was part of the German stereos.
The type of refrigeration cited here are the same type used in camper fridges that run on 120vac, 12vdc and propane.
