In general, the power will not exceed 2.4kw/24h, which means that the power consumption per hour is 0. 1 kWh. It depends on the power of the compressor. I suggest you leave it alone and drive to the lowest gear. If you don't put things at night, you won't need a few electricity bills, but you will switch them on and off frequently. The compressor is prone to problems. If it is not a copper pipe, the pipe is more likely to break down.
