Tire Inflator Portable Air Compressor 12VDC Car Air Pump 150PSI Digital Tire Pressure Gauge Auto Shutoff Tire Pump for Car SUV Motorcycle Bicycle ATV, 2 Year Warranty

I bought this Nilight tire inflator and I really liked how convenient it is. It plugs into the car’s 12V outlet and is ready to use right away. It inflates tires quickly thanks to the 150 PSI capability, and the digital gauge is very accurate, so there’s no guessing about the pressure. The best part is the automatic shut-off feature. Once it reaches the selected pressure, it stops on its own, preventing overinflation and making the process safer. It’s also compact, easy to store, and comes with useful accessories. This is an excellent tool to keep in your car. It works well, it’s reliable, and it can save you in any roadside situation.

This is awesome. I love how easy to use it is. Displays the current pressure of the tire, pumps fast, easy to attach to and remove from stem quickly. This is important especially when it's cold outside. Does everything it says and comes with a warranty.

One tire on my vehicle was almost flat after sitting for six months. Unable to get it to a garage, I ordered this product and it came the next day. Easy to use, easy to set PSI, I quickly filled up my tires to spec, and when the PSI setting was hit, the unit shut off! Surprising! Its a small and compact and great for leaving in the trunk of the car. Its primarily plastic, but the fittings and the hose are better quality. I filled up the bike tires too. Took just a few seconds. So far, so good. Its a good product for the price and the functionality is good. Recommended.

Good quality, very affordable

What a life saver. It was super easy to plug this into my cigarette lighter and inflate my tires when it got cold out. It inflated my tires as a commercial air machine. The cord length is decent but for my SUV, it was a stretch to reach my back tires.

Have only had it for a week, but tested it out on several tires/valves and it locks on very easily and have 0 trouble getting a leak-free seal without even trying. Hardly any air escapes when attaching or detaching, which is more than I can say for the standard type chucks. The gauge responds very quickly and not having to hold the chuck in place on the stem is so much easier. Trigger and release valves both work smoothly and let you control the amount of flow easily. Overall very sturdy feeling. The weak point on any of these is where the rubber hose crimps to the metal fittings, we'll see how that holds up over time (probably best to not leave it connected and under pressure all the time, but that applies to any air hose). The rubber itself will eventually crack if you leave it out in the cold or direct sun, but probably not for many years. Actually they should sell a replacement hose/chuck assembly, I would have bought an extra just to have it. My old Husky one from Home Depot has had cracking rubber for years, the inside has a reinforced woven section and it does not leak, so that has been cosmetic only, I'm assuming this one (like any rubber air hose) is probably of similar construction, we'll see. I don't have a perfect reference gauge that I can compare to, but I have an old digital gauge, and both my cars have TPMS. I tested on my car that has been sitting (air in the tires was at a stable room temperature so no pressure fluctuation between readings. After running the built in calibration on my old digital gauge, it read 29.8 and 29.9 on my rear tires. This Nilight read 30.6 and 30.7. The TPMS in my car (which does not give decimal places) read 31, which means it is somewhere between 30.5 and 31.4. So as far as I'm concerned the Nilight is right within the accuracy range it advertises and more accurate than my old digital gauge. It also reads much faster than the old one and is far easier to see the readout. I also tested using a couple traditional pen testers and both showed between 30 and 32 (can't really get more accurate than that with those). I then bled both tires with the nilight to 30.0 and after backing out of the driveway (TPMS takes a minute to update) both tires changed to 30 in the car. So I'm confident in what is shown on the display. I'll do the same test on my truck next which runs 80 psi in the rear tires, see if I get similar results at the higher pressure, but no reason to think it won't do well there either. I'll also have to see if I can track down something with very low pressure and try with that too, but since I rarely need to fill anything less than my 20 psi wheelbarrow tire, not really all that concerned with whether it is spot on at 5-10 PSI or not. Got it for $18 and at that price it is a great value. Even at $25 to $30 would be very happy with it. It comes with the Industrial type air fitting pre-installed. So if you have an industrial or universal female coupler, you're good to go right out of the box. I found it to be leak free right out of the box (it uses an O ring instead of thread seal tape, and includes a couple extra O rings). It includes a large spool of teflon tape, I guess in case you need to switch it over to an automotive style fitting. Threads are standard 1/4 NPT so swapping the coupling is easy, though the O-ring seems designed for the included coupling and may not work well with others, hence the teflon tape being included I'm assuming. Also includes a valve stem core removal tool, and 4 stem caps (no cores though). I already have several core tools and cores from various tire repair kits, and honestly have never had to replace a core in my life, but can't hurt to have them around. The caps are always handy to have though, nice of them to toss those in as you never seem to have one when you need it. Couple generic AAA batteries included as well (not Panasonic as shown in the picture, but no big deal). On the topic of batteries, you'll notice that most low drain devices (this, TV remotes, etc) come with NON alkaline batteries. That is because Alkaline batteries, when not used enough, will leak, regardless of what brand they are. They also have a tendency to leak really bad when they are dead. If you do use alkaline batteries in this, remove them if you won't be using it for a while. But better to just buy a pack of Carbon Zinc (non alkaline) batteries for use in all your low drain devices (remote controls, etc). Will save you headache in the future. You can get no-name brands cheap at the dollar store or harbor freight and even some grocery stores, and generally they are perfectly fine quality, but you can find Panasonic Carbon Zinc batteries (called Super Heavy Duty) on Amazon and other places and I'd trust those a bit more. They last a really long time in remote controls etc and are far less likely to leak (still make sure you replace them when they die though as that's when any battery tends to leak badly). Rayovac and Eveready make them too, quality wise those are in between the no name like Sunbeam and the Panasonic.

I bought this after several episodes of low tire pressure. The tire pressure warnings built into modern cars have largely eliminated the ritual of walking around and checking each one with a pencil gauge. But, not only do the warnings usually not tell you which tire is low but often they don't tell you if it's only a few psi low or if you're about to destroy it. After destroying a tire I resolved to "regard all future alarms", but that meant I needed a way to pump up a tire at the roadside, not just at home. So I bought this, preferring something smaller than the hand bicycle pump I already had. Might be more than just a few pounds needed to be added. Well, the device is flawed in a lot of ways. The power cord is about right for all 4 corners of a compact sedan. If you have an F-150 you probably won't be able to reach the back tires, depending on where the cigarette lighter type power socket is located, normally inside the car. My car didn't let energy go to that socket unless the key was on. Then there's a pressure loss between the indicator and the tire, approximately 2 psi -- this will vary based on outdoor air temperature. So, you might pump it up but the annoying alarm will keep showing on the dashboard. The indicator is rather small and not easily read from a standing position. The valve fitting you attach to the stem is OK when it's new but I suspect might not make complete contact later on. The movement of it is a 90 degree arc and it's in the opposite direction from my bicycle pump. You can set it to stop at a particular pressure but I didn't figure out how to do that; there are directions and you should read them, however foolish it makes you feel. There's an "M" button and it is not to measure the current pressure but to convert to metric. There are several air pressure definitions current in metric. The English units are the normal psi gauge. You should read the manual carefully if you want to use metric. Is it kPa's, bar, or something else? Newtons per square cm? I think the manual will make it clear but I don't think a tire pump should require a manual. I don't recommend this device. There must be better solutions. The Amazon search engine is poor too, it gives you 10,000+ hits when you search on "tire pump" without a good way to tell which are the good ones. There might still be a place for the auto parts store in this transaction. Buyer beware.

Surprisingly accurate, I don't how I lived without it for so long.
