Review on Compact and Portable Slime 40051 Digital Tire Inflator: Efficient 12-Volt Air Compressor Pump with Auto Shutoff Technology by Ronald Noel

Works fairly well and connects easily. The only small issue is that instead of using a lever connection, it uses a threaded connection on the pipe. This means that when you unscrew the hose there will be an inevitable air leak, causing your final PSI to be lower than when you inflated it. Also, the pump will stop immediately when it reaches the target PSI, but when it shuts off, the pressure will even out to a level 1 PSI below what you set. I get around this by intentionally setting the PSI 2 higher than the number I'm actually aiming for and using a tire pressure gauge, which works by simply pressing it against the stem to measure the exact pressure.
