Hello forum, one quick question. Should I keep the engine running or turn it off when I want you use the electricity accessory sockets? For example to use the air pump, which takes 30A.
Also when using my car to give someone else a jump start from my battery. Is it better to keep the engine running? or better turn it off?
If by Compressor the OP means a 12V tire/air mattress inflator, I just looked up this one. It draws 10 Amps, and that would be fine to use on the cigarette lighter.
