So, before this year's trip to the Balkans, I slapped a little over my pocket and finally bought a good car day out of my saved money. On previous trips we used classic cooling boxes from Campingaz and Ezetil. However, when standing in a column or in warmer weather, they did not manage to cool the stored things and some of the food we took on the trip to Greece would deserve more cold. So I ordered a change in the planning of this year's trip, I went through the offers of online retailers for a long time, their prices and discussions below them, until I decided on a compressor Indel B TB51A refrigerator. The advantage over the classic thermoelectric cooling box is obvious at first glance at the parameters. The compressor refrigerator simply functions as such a miniature domestic refrigerator. A substance with the mysterious name R134a is used as a cooling medium, which is nothing but tetrafluoroethane. With its help, the device is able to maintain the temperature from -22 ° C to 12 ° C, which is absolutely great for our purposes.
