I have the same frig with a different handle found at Salvation Army for $3.50 without the power supply. They have a peltier with a fan and cool only what's inside the frig and nothing else. Too small don't try to expand the capacity of this cooling chamber. Power rating 4 amps 12 volts. I also found a brand new Waring Pro Professional Wine Chiller for $5 with warranty card there, also missing a power supply. Called Waring and they shipped one free. The wine chiller draws 5 amps the power supply fits the mini frig also. Wine chiller drops down to 37 degrees with 31 programed temp settings. Bottom line save your money and buy a mini frig hell I picked up 5 of 'em as curbside finds that all work, they would be better as there is a compressor below with more cooling capacity for your needs.
