Probably too late now, but I've got one of those Ryobi hand-held air compressors and spare batteries in my car. Doesn't take up much room.
So far, only been used to top off tires when low pressure warning comes in on first cold days of winter, and blowing up everyone's floats at the lake. Hope that's all the use it ever gets.
Safe trip with mom.
I have that Ryobi, and it's already in the go bag. Good add!
