I window-shopped for a car air compressor and there's a variety of them with different performance levels.
Low performance compressors (like 30 liters per minute) have a cigarette lighter connector, but high performance compressors (like 160 liters per minute) seem to draw something like 50 amperes current and only have clamps for connecting to the battery terminals. The latter implies opening the hood which is not very convenient.
What other ways are there to power a short-term load like an air compressor that drains current about 50 amperes off the car electrical circuit?
