Ice: Keeps food cool with ice or ice packs, without using electricity. Suitable for the beach, picnics, and short trips with easy portability.
with Compressor: It has the function of a classic refrigerator like a household one (with a compressor and refrigerant).
Thermoelectric: It does not have a compressor or liquids. It uses electricity to transfer heat from the inside to the outside (Peltier effect).
LPG: It operates without electricity, using the heat from a small LPG flame (propane/butane) to circulate a refrigerant solution (usually ammonia) through the “absorption cycle.”
