Ice: Keeps food cool with ice or ice packs, without using electricity. Suitable for the beach, picnics, and short trips with easy portability.
Thermoelectric: It is an easily portable cooling device that operates without a compressor or fluids, using electric power and the "Peltier effect" to transfer heat from its interior to the outside.
with Compressor: It is a device that uses a mechanical compressor (motor) and refrigerant to lower and maintain a stable internal temperature, providing true freezing and cooling regardless of the external ambient temperature.
LPG: It is a standalone cooling device that operates without electricity, using heat from a small gas flame (propane/butane) to circulate a refrigerant solution (usually ammonia) through the "absorption circuit."
