SEYVUM Tire Inflator Portable Air Compressor, [Cordless & 150PSI Fast Inflation] Tire Pump with 3*2000mAh Battery, Digital Pressure Gauge, 12V DC Air Pump for Car Tires, Bicycles and Other Inflatables

So I purchased this because I saw it running on YouTube to be honest.The tire pump came fast and when I got it I let it charge before I used it.After charging, I took it out to fill up one of my car tires that leaks air all the time.I turned it on and set it up for cars and set the pressure setpoint.The unit zeroed out and then I connected it to my tire valve.The unit showed what the pressure was of the tire and with quick press of the on button the pump started. I was surprised to see how fast the pump filled up my tire.Now.... that was all the good about the pump.Here's what I had trouble this the pump but not something I can't get over.One, the positioning of the buttons will drive you crazy because you will most certainly press one of them just holding the unit in your hands when it's on. not a big deal though.Two, The length of the USB C charging cabled is extremely short, so I purchased a longer one.The hose that connects to the pump is a little short but needs ears on the hose that connects to the pump so you can grab and tighten the hose to the pump easier. I had though I had the hose tight enough but when I turned the pump on, it immediately thought it hit it's pressure setpoint and it shut down.Not a big deal though.Three, Don't leave your pump out in the car when it's cold outside.Lithium batteries don't like the cold and the pump won't last as long.I also found that the batteries need to be cycled to get them going.After charging a few times the pump was lasting longer and that's normal for lithium batteries.All in all I really like this little pump and it's very fast at pumping tires up and if your batteries run low this also comes with a cigarette lighter cable that will power the pump and it's plenty long enough for most cars.I hope this help anyone thinking about purchasing this tire pump.Would I recommend , yes I would

Works very very well. but it’s a bit heavy and slightly large to carry on a bike trip for a long distance, where space/ weight are at a premium. There are much smaller emergency inflation devices out there. BUT if that’s not an issue, the kit is great.

I have bought two of this air pumps. The first one failed with a smoked smell but the service and replacement was impeccable. The vendor is very good and respond rapidly to my request. Would buy it again with my eyes closed.

I've noticed others had trouble with the unit reading zero pressure in a partially inflated tire. If you don't turn on the unit before connecting the hose to the tire, you'll mess up the pressure calibration. I know because I did it too. If you read the instructions, that's what it says to do. But if you do need to re-calibrate it, follow the instructions (by holding down two buttons) to re-calibrate it. Good as new. The unit does seem to work fine as long as you follow the instructions.

I first saw this battery powered compressor being demonstrated by a mechanic whose YouTube channel I watch regularly. He used it on all four of a vehicle's tires to get them back to their specified inflation. It did that and indicated half of its battery capacity was remaining. And, that's just how it works for me. It is not particularly loud and is extremely easy to use. Common inflation pressures are built in and easy to select or you can choose any pressure to 100psi. It charges from a USB port or 12V car outlet. Instructions state you may also buy a separate AC charger if you so choose. I love the fact this is so small and easy to store in your glove compartment. Its hose screws onto a tire's valve securely and comes off with no apparent loss of air. It's a great way to easily keep your vehicle's tires properly inflated.

It worked great as a back up to top off my tires when they were low. Easy to use and did the trick. I have had it just over a year, used it about 5 times, and now the tube that connects the unit to the tire has a leak rendering it useless. I wish there was a way to order a replacement of just that part. Again I liked the product but seems longevity is an issue.

I got this for keeping my motorcycle tires inflated. Had trouble from the start. When I used the the cord on my cigarette lighter adapter the display came on to show OFF. Pressing the On button had no effect. Couldn't get it work. I had to unplug the cord from the unit to reset it then plug it back in. It worked when I ran it on battery. I plugged it into my car's cigarette lighter and it worked fine. A really big hassle. The instructions are not clear. You have to experiment to see what works.The side of the air tube that plugs into the unit doesn't have a separate screw-on mechanism like the other side that screws onto the tire. It's awkward to attach it to the unit. Who knows if the readouts are accurate? Still, I'll keep it and just run off the battery if I need it.

* Update to first review, company reached out to me and offered to send me a replacement unit since mine died. Company stands by their product and has great customer service, so that made me rethink my previous review. *Thought this thing was pretty cool when I got it, but have only used it a handful of times and had it for less than a year and it already died. Will not fill up tires just keeps cutting off like the compressor died or something. Kinda expensive product for it not lasting very long and only getting a few uses out of it.

light weight, screw on to tire value is much easier than the pull down type
