I have the same Makita that Ed has. No, it is not in my Beaver anymore but continues to do it's work in the the garage. I suppose I should not admit to how many compressors I've had, but this is the best one.
As I recall, to get enough useful volume, Gerald has engineered a unique system that uses two of those 12 volt units in tandem. I suspect one would work fairly well on a car tire, but to get what it takes for 100 plus pounds in a Beaver sized tire, they could be working pretty hard and long.
