Ring TYREINFLATE GO 4 Cordless Digital Air Compressor, Rechargeable review
Drivers who want a genuinely cordless inflator for boot or glovebox top-ups and slow punctures, without hunting for the 12V socket.

A well-specified cordless digital inflator with auto-stop and a sensible 12V backup lead for when the internal battery is flat. Good for occasional top-ups and roadside use, but its compact cell isn't built for reinflating a full set of tyres in one go.

- Digital gauge with programmable auto-stop and 4-reading memory — set the pressure and it stops on its own
- Truly cordless (built-in Li-ion) with a 3m 12V DC lead as backup, so a flat internal battery isn't a dead end
- USB-C charging, built-in LED light, 3-piece adaptor kit and a proper zip case — a thought-through kit, not just a pump
- Ring doesn't publish a gauge accuracy figure — treat readings as indicative and sense-check against a garage gauge occasionally
Who shouldn't buy this
Don't buy this if you need to reinflate a full set of four flat tyres in one sitting — the compact 2x2500mAh cell is sized for one or two quick top-ups, not sustained use; a mains-plug or permanently-wired 12V compressor suits that job better.
