Says it can inflate tires up to 150psi. That's a lie! This thing is good for nothing but pool toys and basketballs. I just pumped 20 pounds into my car tire and now it smells like it's all burned out. It specifically refers to four cars, motorcycles, etc. Don't believe a single word. Spend a little more and get a good one. They sent me a new one and it took me 45 minutes to pump 10 pounds of pressure into two tires. The tube connected to the tire got so hot that I burned my hand.
