RAC635 Preset Digital Tyre Inflator

I bought this three years ago and it works like a dream for such a small piece of kit. I just do not understand the negative reviews. The screw-fit to the tyre valve makes sure you have a tight seal, unlike my THREE previous tyre inflators which hissed air like Priti Patel. You DO NOT lose lots of air. You lose no more than you would in a garage forecourt - which is not a lot. I have never had a problem with the cigarette lighter connection to my Lexus so only imagine A) other cars have shity cigarette lighter connections B) the 'reviews' are fake. This little machine has kept my tyres inflated all through Covid-19 and is still working. It has generous amounts of wire and hose and I have never had a problem connecting, inflating and driving away. It is not noisy compared to some and works in the rain! I was initially worried about this but it has powered through many a downpour. If any of my neighbours have flats they come to me now!! (Maybe I should charge them!). I did not expect it to be so robust but it is. Along with my solar-powered battery top-up device, this keeps me worry-free and on the road. I highly recommend it.

* Introduction This handy, compact 12-volt car tyre air inflator pump is super. It is easy to use. You use the cigar lighter to power it. * How to use this pump I lost the instruction letter which came with it, so worked it out by trial and error. You plug it in the cigar lighter port. Press the top yellow power button to operate it and turn it on. When you see the panel lit up, select your p.s.i. or bar, by pressing the small yellow button that's below the screen to select between the bar or p.s.i. To set your cutoff pressure where you want it to stop inflating, by rotating the same small yellow button slowly. Connect and screw the valve connection to the car valve. Press the power button twice and you're inflating the tyre. The clear blue display shows how quickly you're reaching the desired pressure in the tyre. When it reaches this pressure, it stops automatically. The device has control lighting in white and red light too. If you have difficulty with getting this to work, just remove and reinstall the power connector into the cigar lighter a port a few times. Another fix to this not operating, then move the cable around when it's connected. It does work. * Summary This compact tyre inflator is well built and designed. it's well worth the money!

Disclaimer: I generally don't know what I'm doing. Honestly, I really don't. If you are in the same situation, hopefully this helps you and sets your mind at ease. Overall: If you have read other reviews, there are some flaws to the design. The screwing and unscrewing is prone to allowing some air to escape. Overall though? Its a very handy, useful addition to have in the car for that really rubbish moment. Buy it, try it, and leave it in the car for when you need it. Packaging and Postage: Standard Prime. So a robust box, delivered the next day and with the compressor packed safely inside. First Impressions: Good! Its well presented in a nice fabric tote bag/case. It doesn't look too complicated and is exactly as presented on Amazon. Only negative is that the instructions are picture only. Unless you look at it the other way, and that is that it's so easy to use - pictures can detail the process. Design: This is one of the major sticking points of many of the reviews here. The screw on/off of the valve means that at a point, there is air escaping. I would suggest that if you are *that* worried, increase it by 0.5psi. Honestly, the amount of air that will escape whilst unscrewing it will be minimal. The design isn't *that* bad! Other than that, decent clear controls. The torch is brilliant especially since I've just used it in the dark. The cable is nice and long and also the cable management (ie how to store it!) is decent. Both the power cable, which stores at the back, and the air hose store easily enough. The photos are after I used it. Use: Plug it into the 12v socket. Screw onto wheel. Change the required PSI by twiddling the knob. Press the power button. Watch the pressure rise. It really is easy. I have to admit, I didn't let it auto shut off, so I'm not sure whether that will be detrimental - I was watching it and I didn't want to wait. Longevity: I can't answer this yet, but I will keep a close eye on it since so many have raised concerns. At the moment, yes - it isn't the highest quality brushed aluminium switches. It isn't a hard wearing robust sturdy compressor. But it is one of the cheapest. And it is perfect for leaving in the car for the odd time you need it.

This is a great piece of kit to have in the boot of your car....... We use the air compressor about once a week to increase the tyre pressure on our car tyres. With a lot of pot holes around, the tyre pressure seems to deflate quite regular and the warning light in our car alerts us to this. The air compressor is really easy to use: - Plug into the car's socket (cigarette lighter) - Turn the dial to preset the desired tyre pressure - Press start The air compressor reaches the required tyre pressure in little to no time and the machine automatically stops when the desire pressure is reached. The product also has some extra little features which are convenient.... - An LED light and backlit digital display which is convenient for night time use - SOS setting to warn other drivers should you happen to be stranded on the side of the road with a flat tyre - A very handy little zipped case to store the product in I am very impressed with this product and feel that it is very durable and great value for money. I can see us using this product happily for many years to come.

This unit appeared to tick all the boxes and ideal for my daughter, screw on fitting so she doesnt have to press onto the valve and snap a lever. Some people struggle with this and lose a fair bit of air. Simple set the pressure and connect it up and let it switch off when its pressure is reached. Sadly we did not get that far, plugged the unit in and the display was unreadable, trying to select PSI had either kPA showing or PSI and BAR at the same time. Trying to set the pressure showed 0's or 8's. The button fell off when unboxing, there is a small shaft inside the button which prevents it being pushed on more than 1mm or 2mm or so, that is why the button falls off, the button does not have splines to match the shaft also. Seen a review mention velcro straps for the cable? The unit i purchased did not have them. The cable wrapped around (doubled) and passed under itself near the end. Simple and worked well enough. I wonder if there are older versions that were better quality? I have requested a replacement, so fingers crossed the next unit ticks all the boxes and works as it should. Honest review from a genuine purchase.

We used to have an earlier model of this machine until we lost it while on holiday. We liked it well enough to replace it with this RAC635 and have found with surprise a considerable improvement. There is a more powerful pump, so inflation is very quick. I used to find the controls on the RAC630 a little difficult to follow but in this model operation is straightforward and intuitive; you set the pressure, touch the on switch and off it goes, stopping automatically at just over the target to allow for a little loss of air during disconnection. Large numerals indicate the actual pressure (except that they show the target when you are setting it) but small figures above them always show the target pressure. You know where you are, which gives confidence. I think the manufacturers must have been paying attention to customer feedback; a good sign of careful design. We always preferred the screw-on connectors which the Ring has, finding them easier to use and less likely to break. Even with my less than nimble arthritic finger tips, I still have no difficulty handling them. Moving our tyre pressures up and down for a heavily loaded holiday trip was no trouble and almost a pleasure. I have no hesitation in recommending this well-built tyre inflator.

Previously purchased the Ring RAC600 model which was half dead out of the box (powered on but no air, so pointless), so there was a bit a trepidation when buying this model but time and options were a touch limited. Out of the box you can easily tell this model is a true successor to the RAC600 model. Build quality is robust and compared to my past tyre inflators a joy to use. The main thing I've always hated about home digital tyre inflators is that the 12v cable has to be folded into a space smaller than a tennis ball, you can spend as much time trying to put away the inflator as you did inflating the tyres. This Ring model breaks the mold, the cable actually wraps around a circle groove on the rear of the inflator, held securely with velcro tape and the 12v adapter in its own groove, perfect. You also have an adapter for footballs/bikes and an emergency warning light, all stored in a handy storage case. Inflation speed is quick, with most top ups of 5-10 PSI completed in under 30 seconds, the digital LCD is easy to read and to preset with your required tyre pressure (in bar or PSI) using the scroll wheel. It also remembers the last pressure setting used to save the diggging through the car manual!

We have had some problems with it but I would still buy it....first problem is that you need A CAR with it - to plug it into!! Since I bought it for my mobility skoota tyres, I was snookered straight away...like most women, I then did the only thing I could and found...a man...with A CAR who was prepared to do job for me! Having got man and van, he then struggled with compressor while I made helpful comments, laughed, took fotos and then we both got drenched by winter rain....the compressor weather the storm (literally) but was difficult to use, didn't always respond to controls and if not careful would pump air out of tyre not in....but when it did want to work, seemed to have some strength and cut off device worked as it reached pressure....did skoota tyres from flat but seemed to take a different length of time per tyre and given our little 8in tyres, I think an HGV might have needed a lifetime! But job was done, and compressor comes with lots of bits and its own smart zip up case...as a mere woman, I was happy with it.....the man with van declined to add his comments on me or the compressor which was probably wise....tyres not inflated and have wheels again,can travel....compressor case maybe 10x8x4in so neat and (is he listening??) would make a decent handbag/camera case!! Squirrel 59 having fun...26.10.16 - better than flat tyres eh....

Great product, have been using this to keep my car tires on point, just love the convenience. All the cables roll inside the unit, which is great, and are long enough to make it easy to fill your tires. It's pressure gauge is accurate, so I'm always confident they're safe. Recommend it

Mit diesem Luftkompressor läßt sich sehr gut arbeiten, weil das Display Groß und Übersichtlich ist. Der versand erfolgte sehr schnell.

I had it only one day and a guy from work had a flat. It took only a couple of minutes to inflate back to 35psi. Easy to use and compact for storage in my Jeep. Highly recommend this product!

Este compresor de aire me ha gustado. Es pequeño y ligero. Está pensado para ser portable, se enrolla el cable del mechero y la manguera de aire. Viene con una funda de transporte con asa para guardarlo dentro. La pantalla con la indicación de la presión está retroiluminada y los números son grandes. Indica la presión de la rueda en cuanto se conecta, y luego a la vez se elige la presión deseada. Se le da al botón de encendido, funciona el tiempo que necesita para subir la presión, y luego se para automáticamente. Tiene también luz, a modo de linterna, para iluminar la zona de la válvula de aire de la rueda, por ejemplo para usarlo en el garaje con poca luz. Se conecta a la válvula mediante rosca: una vez roscado no se pierde aire y se hincha la rueda sin problemas, pero hay que tener la picardía de hinchar las ruedas media décima más para compensar el aire que se perderá en el par de segundos que se desenrosca (pero vamos, que es normal, pasa en casi cualquier compresor, y es cosa de cogerle el truco). Durante el funcionamiento hace algo de ruido, pero vamos, que es normal también, todos los compresores hacen ruido. Para hinchar entre 3 y 4 décimas de kilo una rueda, viene a necesitar un ratito breve, de unos 20 o 30 segundos aproximadamente. Mientras funciona, como consume bastante energía, no está de más arrancar el coche, por si acaso, para no descargar más de la cuenta la batería. La verdad es que me ha gustado, me ha funcionado perfectamente, y la indicación de presión me da la sensación de ser bastante aproximada y realista (no lo he calibrado ni verificado con un manómetro, pero por experiencia quizá indica una décima de más, pero me parece muy razonable). Yo lo recomiendo, y lo volvería a comprar.

A en croire les commentaires, c'est la roulette, alors si c'est le cas, je suis bien tombé. C'est un cadeau, de mon côté j'ai le modèle précédent qui fonctionne toujours parfaitement. Justement, en le comparant avec mon modèle (https://www.amazon.fr/gp/product/B002Q560WE/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1) acheté en aout 2014 il y a quelques changements: - 1 seul bouton (bouton+molette) au lieu de 3 pour choisir l'unité de mesure de pression + choisir la pression voulue - Un affichage plus lisible - Un bruit plus sourd, plus agréable (ou moins dérangeant :) ) - Des lampes un peu moins puissantes il me me semble Il sont peu encombrants, plutôt rapides, je l'utilise uniquement pour un pneu de voiture qui fuit. Le câble est long mais on ne fait pas le tour de la voiture non plus. Côté précision, comparés à 1 manomètre pro, les 2 modèles sont précis à + ou - 0,1bar Niveau utilisation, c'est relativement simple, une fois raccordé à la valve et sous tension il affiche la pression du pneu. Avec la molette on choisi la nouvelle pression puis on appuie sur le bouton de gonflage. Le compresseur gonfle jusqu'à la pression entrée puis s'arrête tout seul. Le deuxième bouton ne concerne que les différents modes de la lampe
