The thermoelectric is with energy efficiency class A++ very energy-efficiently. By using the most modern, electronically controlled technology and highly effective insulation, these values. Thus, the cool box both during cooling as well as keep warm on extremely reduced consumption values. The electric cool box consumes between 8 and 58 watts - depending on the operating mode and mode. For example, during operation with a 230 V power outlet of the ECO-mode can be set. In this mode the existing indoor temperature of the cool box maintained, uses only 8 watts and is also very quiet. At the same mode of the box consumes in a heat-Mode 52 Watt and in cold mode at MAX setting 58 Watt. If the cool box via the 12V plug is operated, the value at 40 watt in the heating mode and 48 watt in the cooling mode.The Cold mode cools your drinks, food or the like on up to 18 degrees below ambient temperature. In order to achieve a perfect cooling result of warm ambient temperatures and thereby to save power, it is useful if you have previously the respective food and drinks in the refrigerator cooled or the refrigerator already at home at the socket, so that the cool box on a lower ambient temperature and, for example, is not in the preheated car at the local ambient temperature.The heat mode can be used for this purpose, food and drink up to a temperature of +65 °C to keep warm. The warm-hold mode heats up no food, but keeps you warm over a long period of time.With the 12 V & 220-240V-plugs, the thermo-electrical cooling box can be used flexibly. You can via car cigarette lighter/12V-sockets and, on the other hand, at each socket (230 V) can be connected. The length of the cable is sufficient for a comfortable use. The cable to the 12V plug is approx. 1.7 m and 230V plug-in approx. 1.5 m long.With this handy size, you can easily stow away a variety of dishes and drinks. All together, side by side, on top of each other or through the divider separated. For example, with a net content of 25 L find 19 small 0.33 L bottles in one level space and has enough space for dining in airtight boxes or other containers. In Bottles with 1 L capacity eleven bottles in one level. Thus, this does not find food or similar with a flat design. The same at six 1.5 l bottles. The headroom is sufficient for three 2.0-liter-bottles. In addition to the large 2.0-liter-bottles is a lot of space for fresh boxes or other smaller bottle sizes up to a maximum of 1.5 L content.The inside dimensions of H: 34 cm x W: 34 cm and T: 24 cm are designed so that you in different shapes and sizes of drinks and dishes, as well as medicines or similar, what you want to keep cool or warm as needed, can put it. Due to the small outside area of B: 39 cm x D: 31 cm, this represents a size of an A3 sheet of paper, thus, the thermoelectric tucked away with minimal space. With the divider grid, you can use the internal dimensions so split that the base area in 11 cm and 21 cm.This text is machine translated.
