A good inexpensive tire pump that will inflate tires albeit fairly slowly. Hey, I've got time, but this thing is pretty slow even on skinny race tires. More like a bicycle pump. The sensor says it will exceed 100psi. I'll leave it, but wish I'd spent a few bucks more for a faster one. Also, the length of the cord is too short to reach all 4 tires of my car so I had to buy an extension cord.
