Unlike a compressor wine cooler — we’ll let you have a point if you can tell us why it’s called that —a thermoelectric wine cooler contains no moving parts and disperses heat from within the cabinet through a ‘cooling node’. It is a much faster, quieter, and easily more efficient appliance. The trade-off here is raw power. It gets great results, so long as the environment itself is cool and comfortable; this means all thermoelectric wine coolers must live indoors. If the temperature outside the unit is too warm, the unit cannot function properly.
