Maybe they sell this type of product but I could not find one. I wanted to air up hands free so I made a trip to the hardware store. No more holding the chuck for 2 minutes and no more checking tire pressure with a handheld gage.
I snap this on and after a minute I close the valve and it displays the current tire pressure. When open it reads the tank pressure. I run it on a 12volt PUMA.
Anything out there like this? It works great, cold hands stay in jacket pockets while the tires inflate.

My Puma has been great so far. I kept it mobile so I can use it with my truck, off road trailer and the Jeep. It would be cool if it was mounted permanently! The only con is that it is bulky, I keep it in a tote in the back of the jeep with some other gear. Air up time is around 1:45 per tire if I remember correctly.
After trail runs I'll get it out and air up then I become the community air up station once I'm spotted.
