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

Finally we tried it on a few flat footballs and a basketball, using the attachment which cleverly slots in the base. Again it was simple to use and fast to inflate - a handy thing to have for when the kids decide they want to play football there and then. Over the time we've used it, we found it has kept its charge well, even when sat in the boot of the car for a few months. 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 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 Smart storage case allows you to charge the inflator whilst still in the bag, with storage for cable 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

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. 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?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. 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. 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.

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. 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. As an extra bonus, for me at least, the expansion tank on our central heating needs to be charged to 3 bar (43.5psi), which is really awkward to do with my stirrup pump as you have to press it against the wall, making it hard to get the necessary force; with the Ring I can just plug it in and off it goes. When our plumber saw it, he went out and bought one straight away.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. 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. 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. 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. Smart storage case allows you to charge the inflator whilst still in the bag; with storage for cable

Some inflators have 12V ports so they can effectively be used as an extension lead that connects other accessories to your car’s power. If your car isn’t fitted with a USB port, it’s useful to have a tyre inflator with this feature so that you can charge a tablet or smartphone on the road. 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. 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. 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

TireTek RX-i digital tyre inflator

If you want to be equipped for every flat tyre eventuality, the VonHaus Cordless Tyre Inflator has you covered. It will run for up to ten minutes from the supplied 1.5A lithium-ion battery, but if you forget to charge it you can always switch to the bundled 12V adaptor, which comes with an unusually generous 3.5m cable. It has a small, but still readable, digital pressure meter. And you can just set your desired pressure, pull the trigger and let it go to work: it will stop when it reaches the right level.
