autowit Cordless Tire Inflator Portable Handheld Air Compressor for Car Bike Motorcycle Inflatables Pressure Gauge Rechargeable LI-ion Battery 12V DC Automatically Stops

This is a versatile air pump. We have several staffs at home need an air pump. Toys, all kind of balls, swimming rings, and the car tires all need an air pump. This pump works perfectly well for all of my staffs. We just need to preset the PSI for every staff, then turn it on. That is all. It stops once it reaches the presented value. That is very useful and convenient. We don’t need to worry about over-topup. In addition, it is very handy, we can just put the pump inside the trunk and use it anytime.

The media could not be loaded.  I uploaded the unboxing video. It looks like a chordless drill but with a compressor where the drill motor lies. The product comes with everything you need. If you are riding a roadbike, you might have to purchase a separate presta valve adapter. The kit comes with a rechargeable 12v battery and a cigarette lighter adopter in a convenient nylon carry case. This cannot be beat b/c it pumps to set pressure so you will not have to worry about excess air. Great product!Followup:On a 700c 23mm tire, inflation happens at around 2psi per second to accurate psi. No more approximation using floor pump!

This thing works great for what I need it for. I use it on my mower tires because I have to pump them every time I use it. Works a little slower than a car portable pump, really not bad though. The only thing though, is if you want this for the digital PSI, don't buy it. It's unreliable and didn't really work. But I didn't need it for my mower, so I love the thing

It’s small, portable, and easy to use. It has a digital pressure gage that you can set and let it run until the tire reaches that pressure. This is a lot better for me than the last few tire pumps I’ve owned that had an analog pressure gage as none of them actually had the pressure my car’s tires marked so I would have to guesstimate with them.

I used this for car tires and for bike tires. It works well and quickly inflates to the pressure needed. Also, the company has great support. When I had a minor issue with my unit they quickly and promptly helped me.

it nice and light but, used twice only on my third use the items stopped working when I plug it in the gauge doesn't indicate the pressure any more and won't inflate the tire at all. I tried many approach like recharging the battery, bringing all the units to zero !! still no reading no pumping....very very very disappointed.....with this item.foot pump 100% reliability.

Likes : Portable, compact kit, fairly easy to use.Dislikes: Air output is slow, air hose should be longer.

I have a Ford Ranger that only gets used for hauling stuff around the property. It sits a lot and the tires lose air. I got tired of hauling the 30 lb air tank around to re-inflate the tires, so I bought one of these. The tires were down to 15 psi when I plugged the AutoWit in. I blew two tires on one side of the truck up to 25 psi, then re-charged the battery, which took about 90 minutes. I then blew the front tire up from 25 to 31 psi, the other front tire up from 15 to 31 psi and the remaining rear tire up from 15 to 25 psi. No issues. Works good.
