sorted byone reads 3psi high so I have to allow for that too! Might just buy one of these and cut my losses!
Beware! they are all pretty noisy, so I've a foot pump when I just need a few psi. (edited)
Secondly, there is no automatic cut-off, so if you want to set an inflation limit for your tyre of 40PSI, which we would have liked to do, you just can’t. You have to pull the cord off of the valve or turn the inflator off.
The final point is that it can be fiddly to get the line on to the gauge if your hands are that nimble.
Pros & Cons
PROS:
Can inflate a tyre from flat
Can inflate other things, like bike tyres, inflatables, beds, toys
Great price
Really simple to use
CONS:
Fiddly valve adapter, so not the easiest for older people to use
Slow at inflating a tyre if from flat
The gauge isn’t perfect and hard to read compared to a digital reading

I tend to use my floor standing bike pump, especially if only needing a smaller top up. Good workout too😁
The pump does take a while which I found useful. I'd go back inside and come out a couple of minutes later to see how it was doing and then stay nearby until they were fully inflated.
Most of you will use it for a quick top up. Or your tyre will be flat on a journey and you will be with the car anyway.
You can't go wrong at this price.
Still wary of 12 volt as opposed to mains, not quite sure why. Might the thing getting hot be an issue?
I check my pressures about once a month and it still costs 50p.
Oh, for those heady bygone days of free air and I know we can expect inflation on inflation on inflation.
So as things stand this will take two years to pay for itself and still longer if I include the petrol costs when running the engine during use. Then there's the nominal extra weight in the boot increasing fuel consumption over time.
I do understand not everyone can change a wheel but for an emergency I think I'd rather rely on the muscles I've got left, a good wheelbrace and a properly maintained spare than one of these on a hard shoulder in the pouring rain.
But then it's cheap as chips and after all, this is hotukd.......
When I bought mine about 8 years ago I was concerned about just how reliable and true it was, so I checked mine against our friendly local tyre shops, in their workshop, the ones they actually use when they fit new or repaired tyres, I had set my 4 tyres all differently - and their gauge read exactly the same as this little machine.
Mine has helped me, my neighbours and even a little old lady at the supermarket recently and so far I have not had to change a wheel, just pumped a flat and driven to the tyre shops for repair..
They do get a little warm if you have to inflate a tyre from flat, but I reckon a foot pump would get warm as well.
Our new Mini has one similar to this in the boot as it does not even have space saver temporary spare.
They are a heavy drain on the battery otherwise
Edit - just realised it has sold out (edited)
I've been doing this for years with no issues.

One thing that I would like is a push on lever fix to your air valve rather than screw on as sometimes feels like I let too much air escape taking it off. Could just be me. But other than that it's great (edited)
I had the button go faulty so swapped it for the light switch. The light is hard wired on now.
Have ordered this though now as I think all my repairs are showing. (edited)
Very loud though, had a big argument with neighbors once when I was using it to inflate a flat.
As it does not have built in digital preset auto cut off and although it will inflate your tyre it will not give accurate reading of your tyre pressure when inflating as the needle gauge fluctuates wildly.
Using this model will inflate your tyre but it will not cut off at correct pressure which is dangerous.
I have just recently purchased the Ring cordless which I thought would have been better as no wires to faff about with but sent it back same day as faulty.
Have just reverted back and bought older RAC 635 digital inflator with a screw on valve type connector and wrap around cable which plugs into cigarette lighter socket but the newer design plug with removable fuse appears to allow inflator to stay in place whilst in cigarette lighter and not keep cutting out and wiggling about like the previous Rac 635
which was a pain to use although the built in tyre deflator switch was very handy.
BUT i have also purchased a pack of push on type tyre adapter to use with RAC 635 and is working fine.
You merely connect push-on adaptor threaded end onto the the end of the original connector fitted then preset pressure either KPA, BAR or PSI
As for inflating tyres i never turn car engine when inflating tyres as this can cause TPMS to give incorrect pressure readings but this depends on what make of vehicle tyres your are inflating.
I turn on ignition until dashboard lights cone on then plug inflator in at cigarette lighters.
Screw on and wait until all 4 tyres are inflated then remove inflator then switch off ignition then turn ignition back fully on to start vehicle
then Reset TPMS

sorry for long post
Hope this helps 🏴
