Works well, good choice.Had, and still have, a number of compressors and this is the best in this price bracket.

Very fast tyre inflator, better than old analogue ones where you've to guess what psi tyre is at by looking at the guage and also saves you time, because your not having check frequently what psi it's at, this automatically shuts down once it hits the desired tyre pressure set on the panel.

This product is so easy to use that footpumps and gauges become redundant.

This is a valuable companion for a car with run flat tyres, with no spare, and it does the job

This is a great one very easy to use and lead folds away nicely. One thing I would say is to get the best psi exactly is when it stops at the psi the bars will drop a little so turn off and back on again and it will put some more air in and stop again do this about 2 times and you will have the correct amount of psi. And its fast to inflate this is my 3rd inflater and the best one so far

The Ring Automotive RTC1000 Rapid Digital Tyre Inflator looked good quality and I was pleased when I opened the box only to be disappointed when I attempted to plug it into my car's "cigarette lighter" socket. The plug was far too small to make contact or stay inserted, not just a little too small. My car is a 2017 Honda Civic and all other devices I have plugged into its power socket have worked fine. So I can only give the tyre inflator one star because it did not work at all.

The RTC1000 works well and happy with purchase. A number of reviewers have had problems with the power plug but for me it is fine. Needs a firm push but OK. Plugged it into a Ford and it worked without a hitch. Tried it on my Volvo and then my VW - no power. Reason for these 2, the ignition needed to be swiched on, for the Ford it did not.

The pump is great, they've really thought about the features and ease of use: pre-set pressure with auto-stop; a long, wind-up power cord; built in light; large, clear display; big "Start" button; long, braided airline with a built-in deflator; a screw-on attachment instead of those flaky push-on things.

But oh dear, oh dear. That power plug...

The only explanation for sticking this monstrosity on the end of a wire is to physically prevent you from plugging it in. I've never seen a plug like it -- sprung (I use the word in the loosest sense) on one side only with a piece of rebar whose only job is to stop you from inserting it into the 12v socket. I pushed my socket through the centre console trying to put it in, so their design was a success. It’s the best electrical safety device ever.

When faced with silly engineering like this, there is only one thing to do -- take it to bits and hit it with hammers. The side “spring” is constrained by the casing so has no hope of moving more than a hair’s breadth. The end contact presses on the fuse which in turn presses on a piece of axel spring from an HGV. After an hour with a vice, a lump hammer, a MIG welder, cheap cider and plenty of ultra-violence I had tamed these immovable hunks of metal into something that had some give in them. Whereupon I plugged it in an found that I had bought something good.

Other than that, I've no real issues. Mine reads maybe 2 psi less than a calibrated gauge, but it's easy enough to set the target 2psi higher if that’s the case.

Overall, the Ring RTC1000 has got some great features; it’s quieter and much faster than pumps I’ve had in the past; and I really like the target pressure feature. But oh dear, that plug…

The in-car 12 volt adapter didn’t fit in my in-car cigarette lighter socket (Mercedes Vito) which rendered the item useless and so it was returned for a refund.

The easiest and best tyre inflator I have ever used
