This is a basic model where you cannot switch between bar and psi. It is only in bars. You can’t preset a pressure and have to watch and stop manually. A Very basic meter and over priced. Got for one with all features above

Very compact, easy to use air compressor which I use weekly to make sure my tyres are kept at their optimal inflation for fuel economy. This device makes it very easy to achieve. The digital display is clear in bright sunlight and the torch feature is handy in case you need to use it in the dark or to display a warning SOS to others.

I have a large family vehicle and the length of the power cord isn't quite long enough to be able to pump up the rear tyres using the power socket in the front but I do have a socket in the boot so it's no problem but could be for others with only one socket. An extra metre would be perfect!

The length of the hose is just right in case you have parked with the valve at the top, the unit will sit nicely on the floor, I've seen other models where the hose isn't long enough and the unit is then dangling and bashing in to the wheel so this is a plus for me. The only downside with the hose I feel is that the screw fitting onto the wheel can be a little stiff so you have to be conscious to get the hose off the tyre quickly after inflation so as not to lose too much air from the tyre.

All round great tool for a great price.

DO NOT BUY UNDER ANY CIRCUMSTANCES!

Purchased yesterday, delivered today and low and behold it has blown up BOTH of my VEHICLES fuse boxes for the 12V socket, now this item doesn’t even turn on whatsoever.

Clearly a fault.

The RYOBI one is so much better!

Needs 0 stars.

The AA tire-pump works fine … so far (others have had problems - see their reviews below) and it fits very neatly in our oldish Yeti boot - the Yeti now starting to have those well-known/infuriating alloy-wheel air-leakage problems.I think it's worth its £23.32 compared to £1-a-time in a so-often-scruffy/oily petrol-station - and it's so much nicer/easier to do this at home. PLUS ... I've lost all faith in petrol-station pressure-gauges being even remotely accurate. Is the AA pump accurate? It seems so comparing its read-out with my Michelin pressure-gauge.That said the whole thing does feel - and sound! - a bit flimsy ... so, in view of others' experiences, time will tell. I also feel the AA's "endorsement" is pretty questionable. I fell for it to buy this one … but then remembered that the AA isn't what it used to be - we should all remember that the AA is now owned by its second round of "private investors"!

Faulty. I set the PSI target and let it finishing blinking to show it was set. Pressed the button - it started and then stopped without reaching the correct pressure. I was after 38 psi but it never got passed 31 psi. I returned it and picked up a footpump at Halfords.

Unfortunately I had to return this item as I found it too difficult to remove the screw valve from my tyre without letting almost all of the air out that I'd just put in! The cap that you have to twist on to your tyre valve goes on ok, but when it comes to removing it, the wire itself starts turning at the same time so it's really difficult to remove it fast.Besides that, it inflated my tyres with ease and it took seconds! It's light and simple to use, with exception of the valve, and the flashing light on the side is a nice touch too. The cable is long enough to reach all four tyres and it's so compact that you could easily put it in your glove compartment! I would recommend this to those who have strong enough fingers and wrists, but I'm afraid it's not for me.

This is great for the car at 35psi but I primarily wanted to use it on my caravan and that’s where the problems started. According to the product specifications it should inflate to 100psi but when I tried to get my caravan tyres to 85psi it just died. It blew 2 fuses in my caravan and after I replaced those, the fuse on the inflator blew. So, not impressed. Doesn’t do what it says on the tin!!!

The AA tyre inflate connector was incompatible with the 12V socket on my Vauxhall Astra h 3dr mk V. No amount of coaxing would get a connection to power. If it fits your car good luck because for what it is it is reasonably good value.Just a shame in my case that a product with the AA name attached to it does not fit a popular UK vehicle!All my other items attach without a hitch to the socket.

Does not show true reading. I thought I had pumped my tyres up to 40psi (according to the tyre inflator) so as I could take a heavy load. However when I went to deflate my tyres and checked with a draper manual pressure gauge, the tyres had not been inflated above the normal pressure. Waste of money.

Useful to keep in the boot and small enough to not get in the way.

Power cable (cigarette lighter style) is a good length to reach front and rear tyres (have to switch door/window you put it through to switch sides). It can also be coiled (has to be neat though) and fits in to a compartment on rear. Same can be said for airline but it coils into a recess on one end. The end of the airline has a screw type adapter and creates a good seal to valve.

There is a LED torch on one end that has proven useful when I lost the valve cap in the dark, however it doesn't have (or really need) a very long range.

The LCD display is lit and easily legible and can be switched between psi, BAR, etc.

Plug it in, connect airline to tyre, check current pressure (reasonably accurate but prefer a dedicated gauge for final check), set desired pressure and hit on button. It seems to inflate to a pressure slightly above set pressure, possibly to allow for any leakage as you unscrew airline and then stops the pump.

The pump will remember the last set pressure so if you're doing multiple cars (bloody family) double check what you need.

As for reliability, I've used this numerous times over the last 12-18 months (occasionally multiple times I one day) it's still going strong. If you're running it for long periods or repeatedly allow it to cool down as the airline will get quite hot. Heat production is a natural side product of compressing air.

A good pump for a good price.

UPDATE:-
Nearly 3 years on and besides picking up a few scratches and one of the small rubber pads on the back (act like feet) vanishing it still works perfectly.

I've seen a few identical pumps with the only difference being the branding, not sure if quality is the same/worse/better but if you look around you might find a good deal.
