AUTDER Tyre Inflator Cordless Air Compressor, 21V Battery and 12V DC Cable Inflatable 180PSI Max Powered Portable Pump with Digital Pressure Gauge for Cars Motorcycles Bicycles Balls, Yellow

I bought this to replace a Bosch Easy Pump which lasted just 1 year and 7 days, which was a great pity as it was a very small and efficient pump, that is, whilst it lasted. Perhaps, in hindsight, I was expecting too much from such a small unit powered by a 3.6v battery, that technically developed 150 psi, and made a very loud chattering noise when generally topping up my car tyres within a typical range of 32 to 36 psi.So, in choosing a replacement, I spent quite a lot of time researching, and I am grateful for the helpful comments left by other Amazon customers. In the end, I chose the Autder and having used it about 6 times on various cars I am very pleased with its fast, accurate performance, delivered at a relatively low noise level. A 21v DC power output, capable of delivering 180 psi, should mean that it has lots and lots of spare capacity and in terms of its typical every day usage, is not operating at anything like its capacity, which I am hoping will result in a long life.Given that these pumps generally 'live' in car boots, it is great that it come in its own zipped case and that case has a pre-formed foam liner to keep it from the inevitable knocks and bumps. Of course, it has more uses than inflating car tyres and comes with a range of attachments to also blow up air beds, footballs, bicycle tyres etc. and the air pressure range can be pre-set - as well as a target psi which, when reached, automatically switches itself off.

I had to invest in another tyre pump because the Jeep cigarette lighter and the Jeep power plug is only fused at 7 amps so I could not use my original electric tyre pump which takes 10 amps .After looking around I found this Autder cordless tyre pump .Yes it was expensive but the thing that I found very useful was that it actually comes in a fitted zip up case with the tyre pump , battery , battery charger and all the fittings + the user manual .Once I had charged the battery I tried pumping up all 4 tyres on the Jeep which was very quick and easy to set the tyre pressures and also very quick to pump up all 4 tyres .I have only 2 criticisms namely :-1 - Even on an overcast day the display israther DIM and you have to get it at justthe right angle to be able to read it .2 - When I saw that the battery was 21volt2amps I thought oh good my leafblower battery is 21volt 4amps I will beable to have an extended run timewhich will be useful going by otherreviewers saying that the batterysupplied does not last long enough totop up 4 tyres .Unfortunately my leaf blower batteryalthough the right size and type theslide on fitting was different ! So I hadto buy an extra Autder 21volt 2ampbattery which I have charged but notactually needed because the original onehas not needed recharging even afterseveral tyre top ups ! I keep the extrabattery charged with the tyre pump - justin case .Apart from the above criticisms this is an EXCELLENT tyre pump well worth expense .Well done Autder !

Pros: Very convenient & very effective - really useful, but only for 4+ months, hence one-star rating.Cons: Purchased Jan-2024 - stopped working suddenly May-2024.Battery shows fully charged but display shows nothing and no controls work at all.Image shows the moment it died (inflating a VW-ID.BUZZ tyre). Inflated tyre sufficiently to get it off the road, then inexplicably died.Very disappointing...UPDATE: following the comments in the earlier review, the customer service team from Autder contacted me & immediately supplied a replacement item - the complete item was delivered the following day: an impressive turnaround. The Autder tyre inflator is a very convenient unit to use so my hope is that this replacement will have a longer life.

This is an excellent product which I use to pump up car,work van and trailer tyres which it does without a problem and saves me a fortune on using garage fore court pumps.The battery failed after a couple of months and refused to charge which was disappointing.Contacted the manufacturer by email and shortly after I received a reply to confirm my order number and address which I did and was told they would send out another battery within one to two days.Sure enough two days later a fully charged new battery was received.I am very impressed with the service from Autder and would highly recommend this product.Thank you Jackson from Autder, great customer service😁.PS-No I don’t work for the company but just believe in recognising excellent customer when I Get it😁

Used it same day as it arrived. checked two sets of tyres and inflated as required. used twice in the next twelve months, checking battery was charged every now and then. My mrs, had tyre troubles so i took it out and tried to blow up the tyres. The inflator kicked up and blew up the first two tyres and then died. I put it on charge and I fully charged it and then blew up the other two tyres. put it away and then a month later had to blow a tyre up which it did. Fully charged after it and a week later needed again and the battery was dead. so had to use the supplied cable. Looked at the other reviews to see its common to have the same symptoms. Great while working but I need reliability. Battery charging lights are stuck on now. Checked when purchased and was out of warranty by two weeks

A good bit of kit. Plenty of adapters. There is one adapter is a bit of a mystery. Not listed in the instruction manual.Robust construction.Quick tyre inflation.

Had a cheap one but car tyres seem to deflate quite often- this is very fast and easy to use plus use weekly on my bike - battery still holding full charge - worth the money

The best. I have used in my van. It’s fast and easy.
