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

With drivers at the forefront of the development process, Ring has launched a new cordless tyre inflator. 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 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: 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.

Naturally, tools such as these need to be as convenient as possible, and as space can be limited in cars, and especially with motorbikes, Ring has ensured that this tyre inflator is as compact as it can be, which also means it’s light, so it’s easy to move around the vehicle and top up the tyres. Additionally, there are multiple LED lights on the tool, so inflating tyres can be done at any time. 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. 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.

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. 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.

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 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.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. 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. 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
