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. As you can imagine, pricing is one of the most important factors of any purchasing decision. We can find the perfect product for our needs, that fits the brief in every single way.

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. It doesn’t look quite as snazzy as some of the others, thanks to the fact that it’s adorned in a cheap-looking silver plastic, but after all, you’re squatting on the ground with grease on your hands — elegance is already out of the window.

Pros

Once the preset air pressure is detected, the device cuts off automatically. You can leave your tyre inflator unattended and do something else while it is operating. The Makita MP100DZ also features built-in LED light intended to illuminate the work area, something that nighttime drivers would want to have. On the other hand, the Ryobi R18I-0 includes convenient onboard accessory storage.

The entire device sits on five rubber-ended feet, which allows it to sit on the ground and coolly inflate your tyres without moving around too much, an issue that afflicts a lot of tyre inflators.
