Tire Inflator Portable Air Compressor, Auto Car Tire Air Pump With Tire Pressure Gauge (150psi), Cordless DC 12V Electric For Cars Tires, Bike, Moto, Balls, Emergency Lighting, Power Bank Function

Perfect for bikes, cars and other inflatables. Best bang for your buck and works well.Love the fact that when you set to ideal PSI it stops. Inflation rate is awesome. Durability seems to be pretty good. Easy to operate. Best of all, it's compact and easy to carry. The rechargeable on USB-C is a major plus as well. Strongly recommended!

First the good news. The pump does inflate things, and its battery life on its first recharge is somewhat better than our last similar pump when it was new, and far better than that pump after two years of use (hence why we bought a new one). The battery life still isn't great, but it's better than the old one. It also has a built-in flashlight, which our old one didn't have, which doubles as a flashing red light for signaling someone, I guess? So, three stars for that.Now the bad news. Either just the pump they sent me is messed up or at least some of these good reviews are from buyers who trust their pump's pressure readout and haven't double checked it with other pressure gauges, or even against itself a few minutes later.I wanted to air up my car tires from 29 to 32, so I set this pump on 32 psi and let it run until it read 32 and shut itself off. I went around and did all five tires (including a full size spare). Afterward, just for curiosity I rechecked the first tire with this pump that just a few minutes ago supposedly aired it up to 32. On the recheck it read 29.5. I then rechecked each one and all five read low again, so I took them all up to 32 again on the pump readout. That made me suspicious, so I then used a separate pressure gauge to recheck all of the tires and they all read around 34 - 35 psi on the separate gauge.I next tried it on a vehicle with an onboard tire pressure monitoring system (TPMS), which the first vehicle does not have. The TPMS read 32 psi on each tire. I used this pump set at 34 psi to increase the pressure on two tires and let it run until it read 34 and shut off. I took a short drive to get a more accurate TPMS readout, and those two tires read 35 and 37 psi on the dashboard readout.Apparently, my air pump's readout is inconsistent and tends to read low. It does inflate a tire, so that part works, but if I can't trust the pressure readout I now have to decide whether to go to the trouble of sending it back or just carry and use a separate, more reliable air gauge when adding air. The problem is, I ordered it a few days before a multi week road and camping trip during which a dependable tire and etc inflator would come in handy. Now I don't have time to spare to return and exchange it for the same model or different brand and model. Who knows, another one might be just as inaccurate.The other annoying thing is the instructions included with my pump are not very helpful. For example, it does not explain the significance of the little "mode" symbols in the top row of the readout, nor how (or why) to change only the mode. There is a car, motorcycle, bicycle, and basketball symbol, and since it doesn't give an explanation, a logical assumption would be that if you're inflating a car tire, you scroll over to the car symbol (or bike, or whatever). Problem is, when you change the mode, it also changes the readout units between PSI and "bar". There is no way to select the car symbol and a PSI readout together. The only way to get a readout in PSI is to select the bike or basketball symbol. Selecting the car or motorcycle "mode" symbol gets you only a "bar" unit readout.What difference (if any) does changing the mode make in the way the pump operates? It doesn't seem like it makes any difference other than the readout units, but the instructions that came with my pump do not explain it at all. The other two readout units shown on the screen are "KPa" and K-something too small to read on the screen and is not mentioned in the instructions, but oddly, those two unit choices do not light up no matter how much scrolling I do. Again, the instructions that came with my pump don't even mention it, let alone explain it.Are all inflators of this same model inaccurate and accompanied by nearly worthless instructions, or just the one I was sent? To paraphrase a famous movie quote, you've got to ask yourself one question: 'Do I feel lucky?'

Bit noisy but good

The media could not be loaded. So far I used this personal air pump on my kids’ bicycles and basketballs, it worked just perfect. My car occasionally loses its air in front two tires when the weather changes. So I’m going to try using this when I need air in my car. I’m so excited to try. Hopefully this little machine will save my trip to Costco (where I normally put air in my car).

It only works plug in charger it does not charge to have it portable waste of money I guess made in china

The first thing that struck me about this tire inflator is its compact size. It's incredibly lightweight and easy to store in the trunk of my car without taking up much space.

It may have been defective but you had to keep pressing the start button for it to inflate. And it wouldn't keep the set psi numbers. Requested refund and received promptly.B

This definitely works. Unfortunately it is not accurate at all.It gets crazy hot when it's operating which kinda freaks me out a little bit. It's cordless, so you need to charge it first which you can do at home or in the car via USB c, or the cigarette lighter, it comes with both cables. It's a decent size, you can definitely manage it in one hand. The valve closure works perfectly and it's easy to use.Overall, I am happy with it. I've been wanting to get an air pump like this for a while. The price was great and I'm glad I got this tool.It's really versatile, it comes with a lot of attachments so you can inflate a lot of different items, bike tires, balls, etc. I bought it for my car tires, and it definitely gets the job done. I just need to follow it with another instrument and actually need to deflate the tires quite a bit to get the right PSI.
