Review on 🚗 AstroAI Portable Air Pump for Car Tires - 12V DC Air Compressor Tire Inflator with Integrated Metal Structure, LED Light - Suitable for Cars, Bicycles, Motorcycles, and Other Inflatables (Yellow) by Guerdon Draper

Only used it to add about 3psi to my 4 tires. The length of the cable is good, it fits easily into the socket. Easy to install on the valve stem and easy to fix. I set the correct psi on the compressor and turned it on. It displays the current pressure and adds 3psi in about 1 minute. It cut off at psi as advertised. I checked each pressure with a digital pressure gauge to make sure the pressure was correct. All 4 tires were exactly as the compressor said. So far I'm very impressed with the device. The only gripe is that it's quite difficult to get the cord back into the compartment it comes in. If you don't put it back in, it won't sit straight. I bought it for my daughter to use during college. Because it is very easy to use (set the pressure and it will stop automatically). It seems to do exactly what I bought it for.
