AstroAI Car Tyre Inflator Air Compressor 12V DC & 160PSI Integrated Metal Structure Digital Car Tyre Pump with LED Light, Preset Pressure and Auto Stop for Car Bike Motorcycle, and Others

This is really good, bought it because the inflator at the local garage is always out of order.So we thought we’d give this a go.Very impressed, the tyre was down to 7.5 psi, and needed to be 33 psi.It too the unit about three or four minutes to re inflate to correct pressure, at which point it automatically turns itself off.5 Stars all day long.Obviously, we will have to see how it does in the long term, but it’s not like your using it everyday, so, so far very happy.

Neat little unit. Not too noisy. Love the quick release and the wiring is of adequate length. Topped-up all four tyres in about 5 mins. Light is a bonus, although I hope not to have to use it in the dark. Wire storage hopelessly optimistic though. Also I would have paid a little more for a simple draw-string bag to keep it in. Overall though I'm very pleased with my purchase and my old manual foot pump has been consigned to the back of the garage.

I read a lot of reviews before opting for this pump. I never 100% trust reviews, so I still didn't know exactly what to expect. I'm so glad I bought this. Small and neat, easy to use and, believe it or not, reasonably quiet! It was the only one I found that you can run for 20 mins before resting it to cool down, you can wrap up the 12v cable easily back into the pump stowage area and the air line stows neatly around the pump, allowing you to store it back in it's box and neatly in your vehicle. It quickly and accurately bought my tyres up to the correct pressure, only about 4 PSI needed in each, but my spare was down to 35 PSI, should be 55 PSI (VW T4 Transporter) this was easily inflated back to pressure in 4 minutes and auto stopped when done. The valve clip loses some pressure on attachment, but you can detach it, when fully inflated, nice and quickly with no loss of pressure. Metal pump body, so should last and a 2 year warranty.I am very pleased with this purchase, no more hunting for a working air pump at fuel stations and sitting in queues. I remember when 'air' used to be free!!! It is again now for me!! I'm glad I went for this model as I almost bought a cordless, hand held one, with this type, you don't get nasty vibrations in your hand and have to crouch by your tyres whilst inflating them!! If you need a small air pump then I highly recommend this little beauty!!..

It seems reliable and the cables are long enough to reach from your 12V ports to the tyres around the car, I've only used it on small family cars so far (e.g. VW Golf) and no problems. If your tyre pressure is very low it can take a few minutes to fill up to manufacturer recommended pressures but that's expected.Super easy to use and you can just set it going, it cuts off itself when the tyres reach a certain pressure. It doesn't overheat or get too hot & seems robust.

Good quality much better than the all plastic ones value for money good size too

I had an old tyre inflator which stopped working properly. Looking online this product seemed well rated and was on discount. The item is relatively compact and light. It was easy to use and inflated the car tyres very quickly. I did test the tyre pressure accuracy using a separate different grand tyre pressure sensor. This tyre inflator seems to under report pressure by 1% (e.g. a pressure of 34 PSI becomes 33.7) but this could also be partly due to loss of pressure when detaching the tube from the tyre or when connecting the pressure sensor to the tyre. Overall it does the job sufficiently well and quickly.

Recently purchased item as a replacement for a compressor which is over 20 years old.I've used it once and it was very simple to use. Plug the 12V plug into your car's socket and attach to the tyre that needs to be inflated. Use the controls to select the unit you which to use. (It toggles between psi, bar and kPa.) Use the buttons to select the ultimate pressure you desire and switch on. The device will stop automatically when the pressure is reached.It also has an LED on the side, which would be useful in the dark.Does what it says on the box. Simples.

Arrived in good order. Instruction dead easy...N.B you do need to start up the car before checking the tyres. Old compressor failed... as the clip onto the valve had weakened so the pressure blew it off! and the tyre got flatter each time I tried to blow it up. So needed a quick and good replacement. I've only used it once so can't vouch for its longevity but having spent more time than I'd like trawling through reviews from cheap to expensive this seemed to hit the sweet spot . It's light but not flimsy...easily and securely attaches to the valve with the old lever mechanism (had been looking for the newer screw-in coupling but these aren't always well reviewed) and the tyres were as they should be within a few minutes. From 14 to 31 p.s.i. took maybe less than a minute... and inflation stopped where I had set it. You'd need to be a magician to get the wire back into it's storage place , and it wouldn't do the wires much good if you did...but that no big deal unless you're very tidy-minded. It was the same on my previous model : )
