Review on FOVAL Digital Tire Inflator: 250 PSI Pressure Gauge & Compressor Accessories for Accurate Inflation and Easy Connection by Solomon Baron

This device is a MUST HAVE for any tire owner. Gone are the days of checking the pressure, adding air, checking the pressure again and then fine tuning it. You plug in the compressor, read the tire pressure, and then pull the trigger to add air. As you add air, read the compressor outlet pressure. Release the trigger and you will read the tire pressure. Large digital display with backlight and powered by 2 AAA batteries. A big plus is the ability to pressurize 250psi. Customs service. I have several trailer tires that require 180psi, which is out of range for any digital or mechanical gauge I've had. Reliable in sub-zero temperatures, very cheap and well made.
