Hi guys, I have all kinds of stuff in the trunk of my Golf7 that pulls a lot of power. That’s why I usually hang the car on the charger once a week and in winter actually every day. I have a CTEK MXS 10 as a charger. Unfortunately, I don’t have a heater in my car and the car is outside. That’s why I already got such a small 230V heater last year. So far, however, I have stuck the supply line to the heating in the door. Unfortunately, it’s not so the Wah I have a 230V cigarette lighter part that could supply the heater. And since I will charge the car over night anyway, it would be a good way to have 12V permanently. The question would be whether it is a good idea. Above all, the car has an AGM battery and I have an AGM battery, especially because the pipes were relatively stiff at minus temperatures. An alternative would be a socket or 230V in the interior, but I didn’t want to do that anymore. always charge it on the AGM function of the charger. Can I supply the voltage converter and the heating so via the charger?
