What types of coolers are there?
A passive cooler doesn't cool automatically. You use this cooler in combination with separate cooling blocks. That's useful when you don't have a power outlet nearby, such as at the beach.+ Light weight.+ Noiseless.+ Affordable.- Limited space for bottles and food.- Dependent on the ambient temperature.
You use a thermoelectric cooler in the car or truck, because it usually runs on 12 or 24 volts. You can also use some coolers at 230 volts, provided you have an converter. Make sure that the products in the thermoelectric cooler are already a bit colder. Since the cooler cools to 20 degrees Celsius relative to the outside temperature, you won't get an ice-cold bottle from the cooler at tropical temperatures.+ Light weight.+ Often inexpensive.- The cooler is not silent.
You use the absorption cooler in any place that you want. It uses different energy sources: 12 volts, 24 volts, 230 volts, or gas. Always keep the rear free so that the warm air can escape from the cooler. In addition, always place it on a flat surface. An absorption cooler cools itself (without cooling elements) to 25 degrees relative to the ambient temperature.+ Makes little noise.+ Cools itself (without cooling elements) to 25 degrees relative to the ambient temperature.- Power consumption is relatively high.
You use a compressor cooler in the car, truck, or caravan. The cooler runs on 12, 24, or 230 volts. The cooler cools itself (without cooling elements) at a constant temperature. After all, the ambient temperature has no influence on the temperature in the cooler. The compressor cooler cools and freezes.+ Independent of the ambient temperature.+ Freezes.+ Relatively low power consumption.- Sound is audible.- More expensive.
