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

Product Information

Comes with a 3-piece adaptor kit for small inflatables such as sportsequipment and Presta bike valves. Other than road rescuers, this would suit camping and caravanning supremely well, where you’ve got a bit of extra space to carry it and perhaps a leisure battery to hook it up to. Ring could extend its usefulness by offering this pump with a couple of different power leads though. If it was easy enough to fit a three-pin plug for example, I’d happily leave this handy unit set up in my garage. Users will also appreciate the thoughtful design elements, including a potent built-in LED light to illuminate the wheel valve in poorly lit conditions, which can also serve as an emergency light. Furthermore, the RTC4000 comes in a smart storage case, which cleverly allows the inflator to charge while safely nestled inside. The inflator's compact size and lightweight design make it easy to transport, making it an excellent companion for motorcyclists and cyclists. Larger inflators include rechargeable batteries, which make them completely portable. These are a better option if you want to pump up, say, bicycle tyres, without having to wheel the bike next to your car. You may also need a larger inflator for tyres that need higher-than-average pressures, such as a larger van or campervan. What about extras?

I’ve used it to top up car and motorbike pressures and once to seat a stubborn tubeless tyre on a mountain bike. I like the screw-on fittings and long hose but generally think a digital gauge is easier to use than an analogue one. It’s a hefty bit of kit, but super speedy and surprisingly quiet. We timed how long it took to inflate a 15-inch tyre from 20-30psi, noting the pressures displayed before and after, plus the ambient and working noise levels. We also timed adding 5psi to a space-saver tyre, to bring it up to 60psi. To help drivers save time, this tyre inflator also has a memory function, so the user can save different tyre pressures and activate them easily from the home screen, and it also has an auto-stop feature so there’s no risk of over inflating the tyre, which can be as dangerous as an under inflated tyre. Smart storage case allows you to charge the inflator whilst still in the bag, with storage for cable Nothing: Light-weight, powerful, independent - It pumps up vehicle tyres, bicycle tyres and footballs (adapter included), wherever you are, and whenever you need it. How to use this item:It’s noisy, dishing out 77dB in operation. And the pressure gauge can be difficult to read since, because it goes up to 250psi, that crucial 0 to 60psi zone is crammed into the first quarter of the dial. However, it pumped up our test tyre from 20 to 30psi in just under two-and-a-half minutes, with no fuss or faff. It’s a shame that the supplied accessories are so basic – just a ball inflator and two adaptors for inflatable toys – still, if you’re looking to spend as little as possible, then the Storm Force Mini does the job. Free Delivery is not available for Over-Sized parcels, such as Exhausts, Radiators & Headlamps - For details on these items please see the 'Oversized Items' section below. Tyre pressures are typically between 30psi and 40psi (or 2 bar and 2.8 bar). How to test your tyre pressure

In the box you get the inflator as well as a carrying bag and a bottle cage attachment so you can carry it on your bike. The unit is charged via a standard USB cable that's supplied.Size is probably the most important thing. The smallest inflators are around 20 x 20cm, so you can leave them in your car without losing too much luggage space. The best don’t skimp on the length of the power lead and air hose, which makes it easier to reach all four valves. Most can be preset to stop inflating when your tyre reaches the correct pressure.
