Indispensible accessory, when using a thermo-electric cooler when travelling, camping or for home and office users. Just plug in, and the thermo-electric cooler runs on 240 Vdc mains supply. Specially developped for compatibility with the Campingaz® thermo-electric coolers, we recommend using Campingaz® transformers exclusively. Thanks to our Autoswitch Sytem, if the input voltage varies, the output power will remain at 13 Vac.
