AstroAI Cordless Tyre Inflator Air Compressor, 12V DC and 20V Rechargeable Battery Dual Power 160PSI Portable Handheld Car Tyre Pump with Digital Pressure Gauge for Car Motorcycle Bicycle Ball

Great piece of kit. Only used it so far for topping up my car tyre pressures and its coped with it effortlessly. Very accurate pressure gauge, first time I’ve had my tyre pressures all accurate as shown on the gauge and my cars pressure sensors. It is very easy to use, lightweight and portable. Battery life appears great and I’ve only charged it once since new. Absolutely recommend and never need to use the garage forecourt pumps again. Probably my best ever Amazon purchase.

Without doubt THE best tyre inflator it’s tidy, compact, powerful, easy to use inflator that I have ever used. Pumps all 4 tyres in 12 minutes, that’s including walking to each tyre Easy to read digital dials and stops when correct pressure is reached So good that I have also bought my son one

Works well, seems to be accurate. Battery can be charged with USB cable or charger. Unit can operate from the battery, or via a cigarette lighter socket in the car. Easy to change it between psi, kPa, bar units. Pressure easy to set. Settings not lost when battery removed. Pumps until target pressure is reached. Only downside is that there's no way to lower pressure. Otherwise 5 stars. Update July 2025 Pump display not waterproof. Using this in the rain messes up the display. Imagine that, a car product for outside use that isn't waterproof. So if you must pump in the rain, keep it shielded. Now to see if drying will help, otherwise back it goes. Downrating to 2 stars. Update later in July Seller read the review, issued a replacement and gave some usage tips. Pump not waterproof, use in rain should be avoided and splashes etc should be dried immediately. Store in a dry place. I'm revising to 4 stars because it's a good product, but how to avoid using it in the rain when you have a flat is beyond me. Still, product support and customer service are good. And they didn't ask me to change the review.

Excellent tool for pumping up your tyres Bought this due to the pressure range in the description as I neede a pump to achieve 5.5 Bar or 80 Psi which this one does nicely Easy to use with a long connection pipe meaning you can stand up whilst inflating your tyres Good display and the battery did all 4 motorhome tyres from 4.5 to 5.5 Bar don’t know what it would be like from flat Battery charges quickly and there is an adapter to run it off your 12v supply if needed Great for checking and topping up your tyres when your in a hurry rather than get out a long extension wire so that you can reach the rear tyres

This is on the expensive side but I bought it to replace a broken inflator which plugged into the smoking socket in a car I needed one which could be used without plugging into the car as I own a tesla model 3 which does not have a socket and this inflator can do both which is great I love the fact you can do PSI and BAR as the Tesla recommends the pressure in PSI whilst my SKODA in BAR so I do not have to convert it each time The fact its cordless means it's very quick to inflate the tyres and it is really easy to use as you simply set the desired pressure and pull the trigger It also comes with attachments for other types of tyres which will be handy for inflating the football and kid's bikes Some reviews mention it being loud but it is no more audible than my previous inflator and perfectly acceptable The battery seems good, I topped up the tyres on two cards (about 2 PSI per tyre) which took around 20 seconds per tyre and it lost 1 bar of power (25%) which means it can do generic weekly maintenance without the need to charge each week (you always have the adapter should you run out) It also comes with a 2-year warranty, which is great for peace of mind Can highly recommend

This AstroAI Cordless Tyre Inflator is a great buy, no more bending down to watch the Gauge, it is held in the hand, Pumps all Tyres in just minutes, connects to the Valve Connector first time, snaps on with a reassuring click, Set The Pressure required, Snap on the Valve Connector, Press the Trigger, job done, durable, worth ever penny comes with 1 Battery for fitting to the Tyre Inflator, and 1 Cigarette Power Connector though run the engine while doing this.

Wish I had bought this before now . I have one that fits into socket in car hated it when tyre pressure low came up on dashboard it meant winding all windows down and having to have engine running just to put 3Psi into each tyre on my hands and knees trying to screw adapter onto tyre without cross threading then some always leaked out whilst unscrewing . This gem has taken all that away just put over valve and click holding gun in hand press trigger and it stops when got to right pressure so easy and quick and effortless going to buy my sister one. Yes the bad is on the cheap side and it came with a hole in the bag were something had penetrated it but that is the only down side. I would definitely recommend it to friends & Family

It’s early days, but I am impressed with the first uses. It’s accurate, easy to use and well built. The battery life seems to be good, (and there is still the fallback option of using the car’s 12 V outlet if you have to). I bought this inflator because I was fed up with always having to unravel the lead and plug the old one into the car’s 12 V outlet, shifting the cable as I worked my way around the car. This device is a delight to use and so much faster. On the downside, the bag is cheap, but it is sufficient to keep everything together in the car’s boot
