There are several types of coolers that have been specially developed for use on boats, when camping, or in caravans. They differ in terms of technology, performance, energy consumption, price, and mobility, as well as their intended use. SeaHelp took a closer look at the market.<\/strong><\/p>\n

If you are only planning a day trip by boat in summer when the outside temperatures are high, a so-called passive cooler is perfectly adequate: these coolers are usually well insulated and work without electricity, cooling simply by means of pre-frozen ice packs or ice, which are placed in the cooler together with the items to be cooled.<\/p>\n

These coolers cost between $20 and $80, are silent, do not require a power supply, and are therefore ideal for short trips or as a second cooler. The disadvantages are their limited cooling capacity (usually less than 24 hours), the lack of active cooling, and the fact that the containers are only suitable for hot temperatures to a limited extent.<\/p>\n

However, if you are planning longer trips and do not have a built-in refrigerator or similar on board, you will need to think about adequate cooling for food and drinks \u2013 at least if you want to stay out there for a few days, for example at a quiet anchorage, or if you are planning a multi-day trip to a more remote destination.<\/p>\n

Thermoelectric coolers have a Peltier element that generates a temperature difference<\/h2>\n

This is where so-called thermoelectric coolers<\/a> come into play, which have an integrated Peltier element. A Peltier element is an electrical component that generates a temperature difference when a voltage is applied\u2014one side becomes warm, the other cold. The so-called Peltier effect was discovered in 1834 by physicist Jean Peltier, who was the first to generate cold using electricity.<\/p>\n

Thermoelectric coolers usually work with a 12V and\/or 230V connection. The main advantages are that these types of coolers are inexpensive to purchase (approx. $50\u2013$150), they are lightweight and portable, and some models can also heat.<\/p>\n
