Bests & Worsts Reviews from Amazon

I aired up all 4 tires on my SUV today and it did a great job. I actually really like that the hose end is threaded so that when you attach it to your car tire, even if the unit somehow tipped over, it would not pop off your valve stem. It's easy to thread and very secure. As soon as you attach the hose to your valve stem, it reads the tire pressure on the digital readout. It will tell you the pressure to the 10th psi (32.0psi to 32.1psi to 32.2psi, etc up to 32.9psi, then it will go to 33psi). You can set it to stop at 1/2 psi increments (32.5psi to 33psi to 33.5psi, etc). The wheel to adjust your psi setting is great and allows you to dial in your setting extremely fast, unlike others that have a simple up and down button and seem to take a long time to get to higher psi settings. You can go all the way up to 160psi. This unit will take about 10 seconds per psi to inflate a tire, so it's not nearly as fast as using a regular air compressor, but it is very nice to just set your psi and let it go. It will automatically stop when it reaches the correct psi. All of my tires were low, but my lowest one needed about 10 psi and the rest were about 5-6. When I was finished, I felt the unit expecting it to be hot or the battery to be hot, but neither were. Of course I aired up each tire one after another and probably had it running for about 4-5 minutes total. Not an extremely long time, but long enough that i expected it to be somewhat hot, but it just wasn't. This unit is loud, but not overwhelming. Its definitely quieter than filling a regular air compressor. And if you dont like the noise, you can turn it on and walk away from it until it turns itself off. I attached a 4AH battery to it and it still sat flat on the ground (one of my attached photos shows the unit with a 4AH battery attached). I dont have a bigger battery, but I think if you were to use a 5AH battery or bigger, the bottom of the air inflator would not sit on the ground, just the battery. Probably not a big deal, because it would still work fine, but some people might not like that. I love that it has a led light built into it, you never know when it will be needed. The light is located at the end of the handle (you can just see it on the left side of the picture that shows the 12v power cable) I haven't used it for inflating anything with the high flow tube, but I'm sure it can handle anything just fine. It's great that it has onboard storage for everything included in the package. Everything fits right in or on the unit, so you never have to worry about not having the correct attachment for the job. There is a 12v car plug adapter (the type that plugs into a cigarette lighter socket). That's fine with me, I'll probably only use it with batteries, but it's nice to have the backup cable. I would assume there is probably an A/C adapter available, but it does not come with one. *****EDIT: I NOTICED ANOTHER REVIEWER SAYING IT DOES NOT COME WITH CAR ADAPTER, BUT IT DEFINITELY DOES COME WITH IT, YOU CAN SEE THE CORD IN ONE OF MY PICTURES***** The one thing I wish this had and am not sure why it wasn't added, is a USB port. Of course not a deal breaker, but with a unit like this that might be kept around for emergencies, it would just make sense. The digital readout is very clear and easy to read and it is also backlit, so you can read it anywhere. The readout will show the psi increase as it is filling. Overall this seems to be a well built unit that makes airing up tires (and other inflatables) extremely easy. I would definitely recommend this to anyone, as it seems to be the best portable inflator that I have come across. Buy it. 6/9/19 UPDATE: I have had this since November of 2018. I have now used it quite a few times on lots of different size tires and it's still working great. It's very convenient to use. Great product and I still highly recommend.
