How to choose a 12-volt refrigerator by temperature stability and vehicle power
Portable compressor refrigerators actively cool rather than relying on ice, but they need continuous electrical power.
FDA recommends refrigerator temperatures of 40°F or below and advises using an appliance thermometer.
Size by usable interior shape
Capacity labels do not show usable shape, so measure tall bottles, baskets and compartment depth.
Plan continuous vehicle power
Compressor ventilation openings must remain clear, and the unit should be secured against braking and cornering forces.
Verify temperature independently
Low-voltage cutoff protects the starting battery, but extended parked use may still require a dedicated auxiliary battery or power station.
