I mainly ordered this to check and fill my car's air pressure and so far it has done a great job. I also liked the fact that I could use it to inflate my basketball and air mattress since it comes with 4 jets. For indoor use you need a cigarette lighter converter. The cables are long enough to reach car tires, and to pump air, you need to set the air pressure on the digital monitor first, which is very convenient. Once the air pressure is set, you can fill the tires with air and it will stop automatically when the tires reach the preset pressure. This is a good product for the price and I would definitely recommend it to anyone who needs a small compact portable air compressor.
