The Ring RTC2000 Cordless Handheld Tyre Inflator is a small rechargeable tyre inflator that's designed for topping up car tyres and inflating bicycle tyres, footballs (and the like) and even inflatables. It's light in weight (at roughly 500g) and comes with a two piece adaptor kit for sports equipment and Presta bike valves. There's an LED light and it also acts as a powerbank function if need be.

The instructions say to wait 15 minutes after 15 minutes of use; after this run the pump’s body felt only slightly warm to touch, but taking it apart I found the motor was extremely hot, so I really would give it a break between long runs; it’s not designed to compete with an industrial compressor so be sensible.Given most people are used to tyre inflators being the size of a kids lunchbox with wires and cables, this small handlheld design might come as a surprise. It's about the size of a standard 50cl bottle of water and not much different in weight either. To charge it up took about three hours when it first arrived and since then we've been charging it up between uses. 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. Once the desired pressure is reached, the inflator automatically stops. The most common units – psi – have one decimal place on the display, but it will only show in increments of 0.5. 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. A full charge from completely flat took about three and a quarter hours via the supplied micro-USB cable. I’d have liked to have seen this a USB-C given the popularity of this connector now, but it’s not the end of the world.

Comes with a 3-piece adaptor kit for small inflatables such as sportsequipment and Presta bike valves. Extra long 70cm air hose with easy access storage compartment specifically designed to reduce kinks Complete with three adaptors - a Presta valve adaptor for road bikes, a sports ball adaptor, and a leisure adaptor for small inflatables, the Ring RTC4000 Tyre Inflator proves its versatility and utility for a range of inflation tasks. This cordless tyre inflator is not only effective in managing and maintaining tyre pressures but also proves to be a reassuring presence in the vehicle for emergencies.

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.

With its innovative design and impressive features, the Ring RTC4000 Cordless Tyre Inflator confidently makes its mark as a versatile and powerful ally in any tyre maintenance routine. This cordless tyre inflator is a combination of efficiency and user-friendliness, turning tyre care from a mundane task into an effortless endeavour. Freedom and Flexibility Tyre pressures are typically between 30psi and 40psi (or 2 bar and 2.8 bar). How to test your tyre pressure Smart storage case allows you to charge the inflator whilst still in the bag; with storage for cable Each of the inflators tested here has a gauge that gives you an instant readout that lets you know whether the tyre needs pumping. To use them, simply remove the dust cap from the valve on the tyre and push the end of the air hose over it, before pressing or releasing any catch to clamp it in place. Petrol station tyre inflators have pressure gauges, too, but these aren’t always accurate so it’s best to test using your own equipment. Despite its smaller size, the Ring performed well, inflating the tyre faster than some of the larger models in this test. The Ring also retains a leisure inflator/deflator and is fitted with a Deflate button. We were also a fan of the foolproof knob and display set-up, and the smart carrying bag.The RTC4000, freed from the confines of cumbersome wires, allows the user to navigate around their vehicle with absolute ease. Its cordless design eliminates the issue of untangling wires or needing to adjust the unit to reach the other side of the vehicle. With the power and performance akin to a traditional Ring tyre inflator, the RTC4000 truly shines with its unhindered mobility. Compact and Practical

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. The pressure is usually shown in two formats: bar and psi. There are typically two sets of these. The lowest is for normal use, but you may well see another set of higher pressures for when the car is heavily loaded, increasing the weight that’s pushing down on the tyres. The RTC2000 is ideal for cars, motorbikes, bikes, scooters and other inflatables and can top up a car tyre in under 3 mins and a bike tyre from flat in under 2 mins. A digital autostop feature automatically stops the inflation process once the desired pressue is reached meaning you don't need to worry about over inflation.Cordless tyre inflator, ideal for camping and road trips. The RTC6000 digital tyre inflator can inflate a tyre in just two minutes. Comes with air compressor setting for tyres, and air pump setting for air beds. Can inflate a single airbed in just two minutes. Smart storage case allows you to charge the inflator whilst still in the bag, with storage for cable The RTC4000 has a digital autostop feature that will automatically stopinflating the tyre when the desired pressure is reached. The inbuilt memoryfunction allows you to store up to 4 tyre pressures in either PSI BAR orkPA. Should you have too much air in the tyre there is a deflator valve thatallows you to accurately achieve the pressure you require. 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. The RTC4000 is not just an inflator but also a smart tyre pressure management system. The digital auto-stop feature ensures the inflator ceases once the set pressure is achieved, while the integrated memory function can store up to four tyre pressures in PSI, BAR or kPA. In case of overinflation, a deflator valve is incorporated for precise pressure adjustments. Adaptability and Convenience
