I'm completely impressed by this thing! You tell it what air pressure your tire needs, hook it up, turn it on, and it fills the tire up to that pressure and turns off! How cool is that! You can precharge it, or hook it into the cigarette lighter so it can handle longer inflating jobs. It has lots of extra nozzles and such, but, really, the true value is topping off your car tires for free rather than paying a dollar to turn on an air pump at the local Pump & Go. This is a great addition to the emergency kit in your trunk, right along with the jumper cables and jack.

This has been a very impressive pump to be honest. It's not crazy fast of course being more of an air pump and of course not having its own pressurized tank. But we are seeing more of these anymore, and most built in vehicle ones we see work similarly. I've used this to air up a basketball, as well as top off a few car tires. The pressure seems to be pretty accurate and it really does automatically shut off when the pressure is hit.

Very easy to set up and read, and comes with all of the tips that I need myself. So portable, feels solid and can even charge other devices such as a cellphone . This is one of the few things I'd recommend packing, along with items such as a battery booster. Easy to pop out for a stranded motorist other than yourself as well. Be the hero, in style!

Really like the portability of this air pump. I can put it in a backpack when going biking or throw it in a small corner of the trunk in the car. Easy to use and easy to read the screen. Need to see how good the battery life is, but so far very happy with it.

This is a great portable air compressor to keep in your vehicle for emergencies. It’s easy to set up, and compact , not like other bulky machines. Assembles quickly and fills an auto tire in mins. Love the way you program the desired inflation and then shuts off when reached. Great for any type of tire, inflatable , ball etc . Comes with several attachments to fit any need. Also comes with a nice bag to keep everything together.

Using the pump is very easy. Set the pressure and it'll start pumping. Works great on small to mid size tires. It will pump 2 passenger sized tires from flat to full. I tried on a 315/70/22.5 and was able to go from flat to around 23psi. I was honestly shocked. Great product

This air pump is so convenient and easy to use! It charges quickly and gets several uses from each charge. It isn’t real loud and it works quickly on car and truck tires. The little carrying bag adds to the convenience. Definitely satisfied.
