Portable Thermoelectric Cool Boxes
If you have power on board your boat, but not the room for a refrigerator, then these portable thermoelectric coolboxes provide you a perfect option for keeping food and drink cool on board.
Cheaper than compressor cool box options they are capable of keeping things cool up to 30 °C below the ambient temperature.
They don't have quite the same level of performance as a compressor cool box but you can boost this with the addition of cool packs or ice. They have excellent insulation like any good cool box should.
Some models also feature a heating function, capable of keeping any hot foods warm if required!
