Ring Automotive RTC4000 cordless tyre inflator air compressor car pump. Rechargeable, auto stop, LED light, digital screen, memory function, case and adaptor kit

I've had Ring pumps before. They did the job but I didn't think they did anything a different brand might do just as well. When I needed a new pump I noticed this got good reviews on the internet and was cheaper on Amazon so decided just to get it.What I really like about this pump is it feels like it was designed by people who actually use them themselves, so they know what is needed. Also it feels like they have worked to improve on previous designs. It seems to work faster than my previous ones and it's not too noisy (definitely quieter than before), and the buttons are large and convenient. It's also very easy to set the required pressure. But, it's the little things that I really like: The brass connector makes connecting and disconnecting very quick and easy. The power cable is easily long enough and can be wound in with a winder that folds neatly away when finished with. The air line is very easy to tuck away and the pump itself is compact and comes in a handy case, so it's perfect for storing in the car. It's just a shame they haven't found a way to prevent your hands getting dirty! At least they provide a glove, though, which is a thoughtful touch.I can't say how accurate it is because I have no way to test it but other website reviews rated it for it's accuracy and I have no reason to doubt them. I pumped up all four tyres, recently, to their correct pressure before going on a long journey, and my car felt much better for it (it's quite a while since I last did it and I'd forgotten what it should feel like).I'm happy to give things 4 or 5 star ratings but I don't often recommend devices or services because other people requirements and experiences can vary. In this case, though, I do recommend this pump because it it so convenient and well designed and engineered, not just form over function.

I've had 2 punctures recently, each fortunately slow ones and near enough to get home, but I got to thinking: if/when that happens again do I want to change a wheel (I'm old-fashioned enough to carry a spare), or would I rather pump it up and get to my destination and take stock there? I decided on the latter, which is why I bought this.It's small and light enough to carry with other necessities in the boot. It's obviously not of the robust construction necessary for professional use, but I was pleased to see that the one used by the guy on the YouTube video I found (the pictorial instructions that come with it are far from clear) was battered and well-used, he said it was 10 years old and had always worked perfectly.I've used mine only the once, just so that I know how to work it. I dare say that the gauge is accurate, though I use a separate one. Plug it into the outlet in the car. The lead is plenty long enough to reach all the wheels, unless you drive a stretch limo. It's important to remember to screw the nozzle on all the way until you hear the "pfft" that tells you that the valve is open, press the button (there's only one!) and wait. I must say it was pretty loud and took a good minute or so to put in 2 or 3 p.s.i. so I suppose it would take 10 minutes or more to inflate from flat but that's perfectly acceptable on what I hope will be the rare occasions when I use it.Useful, easy to use and good value.

Good little inflator. Although some say it's bulky, it is in fact more compact than the one I'm replacing.It's solidly built and inflates the tyres pretty rapidly. The hose-to-valve screw on connector is in my opinion, easier to use and more secure than the snap-on lever type I had before.Three variable readouts on the bright clear screen (PSI, BAR and kPi).It's also quieter than my old one, 90db v 97db, and has neater storage for hose and cable which winds nicely back into the body, so avoiding squeezing spaghetti into a recess and having to untangle cable before useI do have a gripe though. The blurb states that 'The long 3.5M cable and 70cm air Hose make it easy to reach the tyres all around the vehicle.' This isn't the case for my car and I suspect other more recent cars which have the 12 volt socket in the boot.The only way to reach the front tyres is to feed the cable through the ski hatch and through the interior of the car. There is then very little slack in the cable which makes it awkward if there are people or equipment in the car. Another metre on the cable would ease this scenario.It may be harsh but I've just been using it in a rain/hail squall and having to open three doors and the boot while faffing about, ended up with the passengers getting pretty wet and grumpy. Nevertheless 4 stars for being a brilliant wee machine but one off for the short cable.

Have used this for my car and works very well. Pumped up tyre effectively and efficiently.Length of cable is more than enough to reach around normal sized car.Pressure to the tyre is very good and sturdiness of the actual cable and inflator is also good.Have not used enough to know battery life but it uses the 12v socket from the car and doesn’t take too much power as it pumps up tyres 🛞 quickly with excellent performance.Features like torch are nice and bright at night. Tuck away main cables and twist to store cable can be little tricky but good enough. Small area to put dust caps is useful.
