Who uses a tyre inflator?

I have a Ring RAC635 air compressor in my boot (bought from Amazon). Highly rated by the car magazines and very quick. I check my pressures every month with it. Takes about 15 mins to do all four tyres but most of that is swapping between the them.

Should of mentioned that I leave the engine running when I'm running the compressor so it doesn't drain the battery. The manual recommends that you do that.

do you not already have one in the boot?

I have used mine with the engine off with no issues

I use one too - never had a battery problem and they're very convenient, especially if you have a slow puncture!

I use one, a lot when i had a slow puncture. With regards battery I have never had the engine running but to be fair to pump up does not take that long and the battery is designed (for stop start) to keep itself in tip top condition I thought.

I bought the cheapest digital one I could was less than a tenner, works a charm although I’ve never had to put air in my tyres in over a year since it was new alloys with no leaking like the gold i had before.

Hi, I use an older version of this:

Suspect the energy required to start the engine is greater than that required to operate the pump, so I leave the engine off.

I use this to test pressures - way quicker and more accurate than the pump

I have a ring one I think, with digital display and yellow power button, not sure of model. Works brilliantly, quick and convenient but only drawback is the screw on valve, wish it had a quick release fitting or push on one like the petrol station ones do as I have to over inflate them slightly to compensate.

With regards to 12v socket, I just have the ignition on without engine running ad suggested by others. I definitely spend more time on vcds than I do pumping tyres up.

I have the Ring one as well - superb. Had it for years without any issues.

Ring inflator. Excellent piece of kit. Saves having to faff around in petrol stations.

I never use it with the engine running. It only takes a few seconds to top up each tyre so absolutely no worries about draining the battery.

Mine does exactly the same thing so I also add an extra psi.

I am yet. To find one that is quicker than a foot pump for day to day adjustments. 10 pumps for each 0.1 bar.

Me too, and the Michelin one I have is well accurate according to Auto Express and a test winner.

I use an inflator accessory on my Black and Decker drill. Works fine, but I check pressures with an accurate gauge.
