As it stands though I’m more likely to reach for my more convenient battery-powered pump when it comes to squeezing a few extra PSI into my tyres. 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. 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
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.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.
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 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 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. 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. 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.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. 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. 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. RTC400 Digital Tyre Inflator. Able to inflate a tyre in 3.5 mins by selecting the pressure measurement you'd like and then pressing the on/off button. Shows pressure readings in kPA, PSI and bar.
Smart storage case allows you to charge the inflator whilst still in the bag; with storage for cable 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.Despite some initial challenges in deciphering the pictograms on the device, the RTC4000 was found to be incredibly accurate and straightforward to operate once the function was figured out. Although clearer instructions could improve the initial experience, it doesn't detract from the inflator's overall performance. The RTC4000 in Action Tyre pressures are typically between 30psi and 40psi (or 2 bar and 2.8 bar). How to test your tyre pressure
