I did not find a really suitable subforum in the area “Knowledge”. I hope to get competent answers to the following problem: Since I occasionally like to drive screws into the tires, I bought a 12-volt compressor for first aid, namely this one: https://www.globus-baumarkt.de/…/ . The part has a power consumption of 120 watts or 10 amps. I have the compressor several times to pump up the tyres of my moun In my W447 Mercedes-Benz Vito Tourer, there is one of the rear rear sockets in my W447 Mercedes-Benz Vito Tourer https://www.motor-talk.de/vehicles/1433509/mercedes-vito-w447 , each with 15 amps. Recently I wanted to adjust the tyre pressure on the vehicle itself. Once again plugged into one of the rear sockets. Since it was in the dark, I also switched on the work light integrated on the compressor. On the second tire, the compressor failed its service. I suspected that the fuse was gone. I then switched to the socket in front of the cockpit (vulgo cigarette lighter), where a cooling box “Dometic CoolFreeze CDF 26” is operated in parallel at https://www.dometic.com/…/dometic-coolfreeze-cdf-26-31594. The part has 60 watts respectively 5 amps. Also this front socket is protected with 15 amps. Again, the compressor failed its service. Today I replaced the two 15-amps fuses, which were in fact by. Own Is it possible to assume that the compressor has a defect in the meantime? Or other reasons why the fuses should burn through? Maybe someone can answer me before I shoot further fuses for testing. If my questions are naive, I ask for forgiveness. I don’t have it with Volt, Watt, Ampere, Ohm.
