Review on 🚗 H Helteko Air Compressor Tire Inflator DC 12V: Portable Car Tire Pump with LED Light, Long Power Cord, Auto Shut Off, Carrying Case - Ideal Electric Air Pump for Car Tires, Bicycles, and More! by Steven Doty

I had a small tire inflation pump but it only ran on 120v. I decided to buy this pump for 12v so I can always have it in my car have trunk. Now I can adjust the pressure if necessary, e.g. B. if I drive to a snowy country, the temperature is 30 degrees cooler and the tires are under-inflated. ALSO - Now I know that if I need a forgotten spare tire because of a flat tire, I can inflate it to the required 60psi. This pump is great. I set the desired pressure and all four tires inflate perfectly. So easy to use.
