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 product. Bought this for inflating my motorhome tyres. Worked a treat. Using the valve snap on connector is much easier than valve screw on versions. Inflated all 4 tyres from approximately 60 PSI to 80 PSI in about 15 .inutes on one battery charge. Tested the 12V connection as well and this also worked well. The auto shut off feature is great as you can just leave it running until it reaches it's required pressure. Better value for money and smaller than some of the other high power air compressors and no way near as loud.All in all I would highly recommend

Good little tool, easy to use, visible screen, easy to recharge and store in the boot, well made

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 2025Pump 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 JulySeller 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.

My car only has a 12v outlet at the rear, and inflating the front tyes was a pain using my existing tyre inflator.So I looked for a better solution, and found the AstroAI Cordless, which does exactly what I need it to.Comes well packaged, so easy to store in the boot, and makes inflating tyres a cinch. It's fast and easy to use, and comes with every accessory you'll ever need. As it says in the title great product.

The pump inflated my tyre unfortunately the readout was on zero.Also after setting the limiter it continued on and never stopped.I had to use a separate pressure gauge to check results. Returned for refund. ×××××UPDATE ×××× After I was disappointed to receive a faulty unit, was contacted by the seller who was exceptional from initial communication to resolution in fact it was first class customer after sale service.I received a replacement within a few days. Happy say the item is very good. Performance is better than expected,(See attached video it's the last 40sec to show its performance the tyre was a space saver 125/80/15 it was completely flat) I am happy with its performance after that little test. All functions work flawlessly.the screen is nice and bright,psi,bar,kpa just pick one.It weighs just shy of 1.2kg with20v battery, the design is like a cordless drill and balanced means its effortless to use. the ergonomically rubber non slip crafted handle is nice an comfortable it even has a light for those winter nights. The battery also has a convenient 5v usb port, so you can charge your phone. It comes with the obligatory tapered/needle adapters a valve extender.12v dc plug, the hose is extra long which is very welcome. In the video you can see the pressure limiter working at 30 psi.I don't know how many flat full size tyres it can blow up as I've only tested on a space saver spare,if it does run out of energy there is a 12v dc plug for use in the cars power outlet.It's really well built, very sturdy, this won't shatter if dropped. A uk 3pin charger is also included in the zip up storage bagNoise level.. well this is very subjective, for me the level is fine, I've had some that are painfull to the ears.Conclusion.. I reall like this it's a nice bit of kit.The seller.. amazing!Best after sale service, I have experienced.

Good quality and fast tyre inflation.

This is on the expensive side but I bought it to replace a broken inflator which plugged into the smoking socket in a carI 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 greatI 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 timeThe 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 triggerIt also comes with attachments for other types of tyres which will be handy for inflating the football and kid's bikesSome reviews mention it being loud but it is no more audible than my previous inflator and perfectly acceptableThe 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 mindCan highly recommend

Works ok, a bit on the noisy side. I don’t know how accurate it is but I checked with a separate gauge and there was a discrepancy of 3-4psi. Overall the product looks good. The bag it came in looks a bit on the cheap side. The battery came charged and that was a positive. Seems a high price just to inflate tyres but having read other reviews I had decided to buy one and hope it lasts to make it worthwhile.
