Air Compressor Pump, 12V DC Portable Digital Tire Inflator with Gauge 140W 120 PSI, 4 Display Units, Auto Shut-Off for Overheat Protection

The media could not be loaded. I’ve used this compressor now to pump up bike tires, car tires, and various sports balls. It works well and is easy to use. At first I couldn’t figure out why it was shutting off. I thought it was getting overheated really quickly and was about to return it until I realized it’s the auto shut off that came from the factory a few psi short of where I needed it to stop. Then I started using the auto shut off and it’s really handy! My favorite part of this compressor package though is that it’s so well thought out. It comes with every adapter you may need and the normal valve stem connection screws on rather than having the finicky switch that many others have. The cord has a small velcro piece that lets you wrap it up nicely and the thick main hose has a plastic clip to keep it wound together. The carrying case is also super nice. My favorite little thought though is that it also comes with extra valve stem covers. Have you ever misplaced one of those when filling your tire with air? It’s so nice to have extras.

Its not a bad pump, just can't start under pressure. My truck back tires take 80psi, now I only ride 65psi when I'm not towing. I screwed in the fitting, and then tried to turn the pump on, well it wouldn't start. So I unscrewed it, turned pump on, first, and then screwed it in about half way, and held it in place, until I got to 65psi (had 58psi to start). Once I did that, it worked great. Mind you, it didn't really shut off at 65psi like it was supposed to, but I was right there, so it wasn't a big deal to me. Overall, it's well made pump, and beats spending 2 dollars everytime you have to feel up your tires.

I love this air pump. It works great for filling any type of tire. I used it for my car and my tracker with no problems. I feel that it's a great value for what you get. The dial to select the air pressure you want is easy to use, and it's accurate. The bag that it comes in is perfect for keeping it in the trunk of your car should you need it in an emergency. The added caps with the attachments just make it a really good value. Definitely recommend getting one if you're on the fence for a compressor.

Why, you ask? The problem is in the design of the air nozzle connector on the pump for filling tires. I have Michelin tires. What happens is that the half-circle shaped pin in the pump nozzle slips right past the pin in the tire air nozzle, making it impossible to fill the tire with air. Then, when you turn the pump on it shuts itself off immediately without pumping any air into the tire. The only way to make it work is to keep trying different positions for the pump nozzle until it finds a position which will push the pin inside the tire air nozzle (when you can hear air being released, you have found it), and then you can turn the pump on and inflate the tire. Looking for the 'magic position' to make it work can go on for a long, long time! I also notice that the air pressure gauge on the pump isn't very accurate, and over inflates (when you are actually able to pump air into the tire!) by about 2 pounds psi. I wish I had tried it out during the return period and sent it back. I'll be looking for another brand to purchase, and I'll be sure to try it out immediately after it arrives.IMPORTANT UPDATE AS OF MARCH 7, 2020:I bought this adapter to attach to this pump, and it solves the problem and allows the pump to work correctly, pumping air into a tire. This is because the pin in the nozzle which is meant to depress the pin in the tire nozzle is made and positioned correctly! If you purchased this air pump and want it to work without much frustration, I recommend purchasing this attachment - https://www.amazon.com/gp/product/B07MX882J8/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1Still, it's pretty ridiculous that I would have to purchase another product, even though it was only $7.59, to make the pump work correctly.

Haven't used it yet, just plugged it into my trucks 12v DC outlet and turned it on. Love the compact rugged feature filled design. How you can set the PSI and it will bring tire PSI to that set amount and turn off. i like the backlit display. I love the hanger for the 12v DC plugin underneath it. Nice grab handle, The hose is decently long. The LED flashlight is a nice touch, the replaceable inline fuse on cord is a brilliant idea. If you notice some of these compressors only are rated for 15mins of runtime then your to cool them down. This one is rated for 30mins runtime then it automatically shuts off to cool down. This is one of the better such compressors.

It seems three is about the best I can give this inflator, even though it is easy to use light weight and accurate. One of the best features of this the automatic shut off if it gets too hot. Having said that it is also the thing that I have to give it a 3 star for. If you are going to use it for an emergency in your car or minivan it would work perfectly. I however bought it to inflate my tire back up after going off road. It worked for a few minutes and then got too hot and shut down. So this does not really work for over sized tires.

At first I thought I was going to repack and send back, I had it all plugged in and connected when I hit the on button it shook one time and nothing. After a few checks and fustrated that I got a dud, while it was still on the on position I loosened the screwy thingamagiggy from the tire air port connection and it suddenly came to life. My tire was at 29.6 psi it had to go up to 50psi, it stopped at 50.5 which is great because when you loosen the thing to disconnect you loose a little air anywaysFor a little chiwawa sized compressor it does a great job. Took about 4 minute's to get up to pressure and it's kinda quiet and stays pretty still while fillingI recommend it

Bought this item based off reviews and price. Would like to give this a better review, but 2 stars is being fair. It worked fine on first use pumping 3 tires. The second time I had to use it, the metal peice inside the valve broke off on one of the tire stems. It didnt last too long and I've had this product for 3 months, only being able to use it once.
