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

Despite being compact in size, the Ring RTC4000 does not compromise on performance. It is designed to inflate tyres swiftly, whether it's a quick top-up or filling up all four tyres on a car. Even a 13-inch tyre can be pumped to 35psi in less than 3.5 minutes. The backlit digital screen provides an easy-to-read pressure setting in any lighting condition, adding to its practicality.

Remarkable Features

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.

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

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.

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

The real-life performance of the RTC4000 stands up to its claims. During a test on a car tyre that had dropped to about 5psi due to a slow puncture, it performed impressively, pumping the tyre back up swiftly and quietly. Notably, the RTC4000 accomplishes this without the need for an engine to run, adding to its convenience.
