A Compact Portable Cordless Air Compressor that can pay for itself
With gas stations charging for air, it's a good investment to have your own compressor. I have a full size compressor, but heavy to move it to the driveway and a long hose is a pain to unroll and roll up.. It's also a pain to fill an air tank to take to the vehicle and often you have to do this several times if you need a lot of air.

With this little compressor, I can just pick it up and set it on the ground next to my motorcycle. within less than a minute or two I can easily get the pressure correct because you can set the shut off pressure while monitoring the actual pressure. The hose has a spot to wind it up and the air chuck snaps into a holder. Uses standard Milwaukee M12 rechargeable batteries, which I already had two of, so buying just the bare tool was very economical and should pay for itself by not having to pay for air, but the convenience is well worth the cost.

Only drawback is it's kind of loud so airing your tires when your neighbors are asleep might wake them up. I haven't used this on a car tire yet, but for airing the tires on my motorcycle it's perfect.

Very handy. Worth every penny.
Pros- faster, lighter ad smaller than I thought it would be. Easy to use, good quality. Light up display is really nice, display is easy to see in bright sun. Doubles as a pressure gauge. Auto set pressure is impressive. The ability to set up, start, and walk away is priceless. Ability to inflate kids toys and balls is an added bonus. My son loves filling his bike tires.

Cons, can’t vent if overfilled. Pretty loud for a small unit.

Easy and lightweight
Works quick and easy for small things, but will also do car and truck tires with ease. Much easier than dragging a compressor out!

So nice to carry a light weight device to check our tire pressure and fill up
No hoses to tangle with
Con I purchased clip on device to attach to air fill instead of slow screw on and off

for emergency use out on the trail with my side by side
I just had to use it for its intended purpose and it worked great

Almost perfect.
Replaced my Ryobi One+ that didn’t last a year. Blows it away. Love the digital setting and auto stop. It would get 5 stars if the screw on nozzle was more flexible/bendable. It was a pain to position it on our mini bikes and wagon. However, once on position, the nozzle screws on and off very easily with minimal air loss. It is a breeze on everything that has plenty of access. Hence the conflicting pros and cons above.
