After reading SIGFORUM positive reviews of the AIRMOTO tire inflator, they went on sale on AMAZON (-33%). I bought one, it arrived yesterday.

Today I conducted a simple test on two tires on my car. Tire #1: AIRMOTO read the PSI at 34.7. I then used my (Project Farm) highly rated ETENWOLF Digital gauge. It indicated 34.7. Tire #2: both read at 34.5.

Either they both are equally off or both are accurate. I'm going with accurate. I honestly can recommend both..

A tip. It has a USB-C jack for recharging its battery. But you have to use a USB-A power source.

I returned my first one as defective before i discovered that. No hint in the little manual. It did come when a USB-A => USB-C cord, but I thought it was optional.

My only USB-A power source is the one in my car. OK, after I learned the trick.

I can attest that mine matches the onboard TPMS in our Expedition.
I ran it dead twice filling a 275/55-20 that was about 15psi low.

Otherwise, it works great for car tires. Used it on my Mini and Fiesta, and bicycle tires for the kids.

I think I have the recharge situation covered. My car has USB-A ports, I have long USB-A to C cables. My Antigravity XP-1 Jumpstarter also has USB-A ports.

When it warms up I'm going to stress test the Airmoto by trying to fill a 245x45R20 from 10psi to 35 psi.

I'll be impressed if.you.get it in 1 full charge.
Also, the fill hose gets quite hot on an extended run.

I'm not going to need it until I need it.

Yep, and in that sense, it's great in a pinch.

For me the primary benefit is that it’s so much more convenient and correct to top up my auto tires with the Airmoto. I can do that in my garage without driving an inch. Topping up the tires to recommended pressure is properly done while they’re cold.

And I used to hate horsing the spring-tensioned air hose around at my Chevron station.

I'll use Costco when we're there, otherwise, the Airmoto is much easier than dragging out my big compressor

I bought several Airmotos several years ago for Christmas presents. We keep one on each vehicle we have.
I only use them to top off 3 or 4 pounds on our vehicles. The tires on my trucks need a compressor for any more due to the size.
I have helped one older lady top off her tires once at a gas station. Her check tire light had come on after the first temperature drop of the year.
I do use them as tire pressure gauges as they match the TPMS numbers.
They're great for the riding mowers, bicycles and even the pressure for the steering on the yacht I run.

Interesting. Could you explain a bit about:
“and even the pressure for the steering on the yacht I run.“ ?

The yacht I run has hydraulic actuated power steering that is pressurized to 35 psi. The little tank in the pump room forward of the engine room has a small hydraulic tank with a valve on top. Lot easier to go in there with the Airmoto than to rig a hose up to the door compressor and drag it up there.
