I was in wonderment of how that would drain the battery Vs how long it would take to fill up , say , a 4.00 x 18 tubed tire.
I have used one of these in a 2litre 4 cylinder 4WD and can confirm they are very quick to inflate a 235/85 R16 tyre. In that case the engine would start but obviously only run on 3 cylinders so no load on the battery.
