Works Great/Awesome power/Easy Use
Needed to replace my old inflator as died after decades. Wanted same type that worked off car not battery, this one works great, half the size as old one and more powerful. Fast and powerfl with easy controls, couldn't be happier, love carrying case for trunk!!! Awesome value!!!

Robust build. Valve nozzle very strong. Operation fully reliable, screen data helpful. Excellent!
This inflator has worked perfectly for me this last week or so, since buying it. Some of my tires have lost air pressure regularly because of the continual sub-freezing temperatures. So I've used this frequently. The build quality is solid throughout. I especially appreciate how sturdy the valve is, and how smoothly it locks in. Also, the power cord is a heavier gauge than a neighbor's inflator that I borrowed. The hose and its connections are strong. I'm very glad I bought this more robust inflator, than the rechargeable battery ones I researched. I use this from my car's power, and occasionally also a smallish 12v power station I have. The digital readout is clear. I like that both the target pressure and current pressure is shown. The current pressure updates every 0.5 PSI. That lets me inflate to somewhat below my ideal standard, to save time if I have to drive a short distance but right away. The speed of inflation seems good, similar to the "conservative" statistics mentioned by some other reviewers. I've tested inflation pressure a few times with a quality bike tire pressure gauge. This inflator tends to over-inflate by about 6-8%, and consistently. About 3psi when tires are inflated to 40psi. So it seems very stable and predictable. The price was very reasonable, for what I feel is a superb product. I highly recommend this.

Quick and efficient
Excellent little device. Simply to use - works quickly and efficient. Small word of warning that this type of device will most likely not last for ever, it probably can only do a couple of hundred full tire inflations and then will fail - but for most folks that will last them years and years. Remember to keep it in the car - and not the kitchen draw!

Compact, accurate and reliable
This slim tire inflator is about 2 inches wide and 6 inches high (rough estimate). This is the second one I’ve purchased—the first lasted over five years with heavy use before the cord gave out, which was likely my fault. It functions exactly as it should and helps me quickly get tires to the desired PSI. If a tire is flat, it will take some time to fully inflate, and you need to ensure the vent isn’t blocked to prevent overheating. The accuracy is spot-on; I’ve double-checked with another device, and it’s dead on. It’s a good value for the money, long-lasting, and easy to store in your car. It plugs into your car’s adapter (formerly the cigarette lighter). Pros: Slim, compact, and easy to store Accurate PSI readings Durable and long-lasting Good value for the price Cons: Can take time to inflate completely flat tires Must ensure proper ventilation during use Conclusion: Overall, this tire inflator is reliable, accurate, and compact. It’s a practical tool for anyone needing a convenient way to maintain tire pressure on the go.

Well designed. Dependable. Good price.
Very pleased. Did everything it promised. Very good price. Electrical cord was of sufficient length to reach all four tires (Tesla Model Y), Air hose looked a bit short but after using proved long enough. Clasp that latches on to tire stem worked very well and was easy to manipulate. It inflated very quickly for its size. I liked the settings which let you adjust it to your desired max pressure. It has a light built in. Great idea. I did not use it though as it was day time. Will likely buy another for my second car as neither of my cars came with spare tires!

This tire inflator is well worth the investment and simple to use for all.
Purchased this unit to replace a similar item that was battery powered. The battery powered unit worked fine initially, but after only a few years the battery did not hold a charge long enough to inflate even one tire a few pounds. Decided to go with this 12V unit and have been impressed. Plug it it to a 12V outlet in the car, start the vehicle, set the desired tire pressure and it works great. Powerful, convenient and easy to use. Once the desired pressure is reach the Inflator automatically shuts off. Filled all four tires about 6 pounds each in a matter of a few minutes. Everything easily fit into the storage case and underneath my car seat. Only downside was there was not an adaptor that would fit my road bike tire valve stem.

Great little Air Compressor
This little air compressor is great. Compact, nice digital read out, great little carry case, works great. Plug it in to 12v , set the psi and it does its job. Very good product for the price.

Great product!
So glad I bought this! It works quickly and easily, and needs no time to charge up! The cord is long enough to reach all four tires, and the design is compact so that it stores away nicely in my car! Great product!
