How do compressor coolers work?

Compressor coolers work like a “real” refrigerator. As the name suggests, they come with a compressor and coolant fitted. The coolant is compressed using the compressor and then evaporated; the gas extracts the ambient heat and the box cools down accordingly. As a result, compressor boxes work reliably and cool – unlike thermoelectric coolers – regardless of the outside temperature. Most models can be set to the exact degree – even minus degrees are possible. But the compressor makes the boxes comparatively heavy.
