Review on 🚗 TEROMAS Tire Inflator Air Compressor: Portable DC/AC Air Pump for Car Tires & More - 12V DC & 110V AC, Digital Electric with Pressure Gauge (Green) by Lynn Cole

I had a nice little AC powered pump but it was annoying because it had a screw cap for the tire valve stems so I couldn't get hold of it quickly. on and off but had to be screwed in and out the whole time. The analog needle wasn't reliable at all, especially as it bounced around so much during use and if you stopped it long enough to see a reading it was off. However. And this winter one of my jeep tires seems to be starting to leak, so when the temp drops below 20 or so I get under 30 psi pressure and I need to fill up. Very uncomfortable to do with the old. This one, a standard tire valve clamp, adjusted the pressure and drove off. The only odd thing for me was that I knew it was supposed to stop on pressure, so I expected it to shut itself off, which it doesn't, it keeps going by just not sending more pressure into it. My gauge and TPMS read the same 41 PSI so I was very happy. Add to that the fact that it comes with a case and can run on both DC and AC, it's a keeper for me.
