Ring Automotive - RTC1000 12V rapid tyre inflator air compressor car pump with preset digital pressure gauge, memory function, 2 min inflation, LED light, carry case, valve adaptor kit

Product Information

These are all useful, thoughtful additions, though it would be nice if there was a compartment somewhere within the device in which to keep them. With its handy integrated light, long power and air cords, this tyre inflator is close to perfection, except for its 12V power connector. In regard to tyre inflators, Ring Automotive offers what is probably the widest range of models available in the UK. The RTC2000 is ideal for motorbikes, scooters and bicycles; and can inflate a bike tyre from flat in under 2 mins or top up a car tyre (25-35psi) in under 3 minutes. Keep a lookout for tyre inflators with extra adaptors that you can keep in the car, so you can use yours to save your breath, as well as a lot of time.

Although, the valve did allow for a few seconds of depressurisation whenever the Ring was uncoupled. It certainly beats the old foot-pump I used in bygone days, and is a lot more convenient (and probably more accurate) than the machines on garage forecourts. However, it doesn’t come with a case, like the admittedly pricier Ring RTC1000, meaning that it’s vulnerable to getting scuffed by other things that you put into your boot. The same can’t be said for the 12V connector, though, which must be wrapped around your hand and cable tied before it can be reinserted into the inflator. Once you have attached the air hose to your tyre using the brass valve connector, the device then operates to inflate it to your target pressure.The AA offers vehicle insurance, breakdown cover, incredibly detailed road maps and now, car tyre inflators. You can even add images of each vehicle and the tyres; the app is limited to five vehicles currently.

The size of the pump is a little larger than the norm, but it feels suitable chunky with thick plastic that should take a knock or three no problem. What’s more, the pressure reading isn’t entirely accurate, although it is mostly only a few PSI out. The RTC1000 remains impressive with its protective, zip-up case, huge backlit digital display and large hand or foot-operated on/off button. The second pistol-type model we tried looked expensive, but it was a hybrid 12V/battery cordless model.The 12v connector can be neatly wound away on a spindle, saving the normal tangle you get yourself into.
