I've got a Ring one as well...had it at least 10 years and never had a problem with it.

I have a twin cylinder inflator which came from Paddock Spares many years ago, they still sell them but they are now over £100, something like 150l/min inflation rate which will fully inflate a standard 16/17" car tyre in just over a minute and a large 4x4 tyre in about 2 mins, no cig lighter connection with these they use far too much current.

There are several smaller versions of these on offer, if you punch twin cylinder tyre inflator in to the search box on your favourite sale site they will come up, inflation rates quoted from 60l/min up to around 80l/min (they all look similar design to me so judge for yourself), some appear to have both cig lighter and croc clips for direct to battery connection and come with a long coiled air pipe, same as the larger version i have, priced between £35 and £50, obviously these will take up more space than one of the smaller types and i would always suggest connecting direct to battery in preference to typical cig lighter especially in an emergency situation.

Might be interesting to compare airflow rates with some of the typical inflators for sale, if you can find the specs, one smaller version i clicked on didn't quote flow rate but suggested a 13" tyre (common size in 1967) would take 4.5 mins to inflate.

What i would suggest, if where safe and possible whenever inflating tyres to keep the engine running, the current involved with inflating a tyre from flat could render you with a non starter, don't want that on the side of a busy road.

another vote for a bicycle floor pump with pressure gauge....

I had a no-name model included with the car. Its plug fell apart but I soldered on a Tamiya connector and run it off a RC model battery. This was partly because it was a poor fit in the lighter socket and blew a fuse a couple of times on the previous car. Otherwise it's been pretty good.

Can anyone recommend a particular brand or model of cigarette socket driven tyre inflator? Looking around, Amazon is full of brands I have never heard of, and I don't want to be relying on those in a pinch, to be honest. Happy to consider any brand if forum members have had good experience though.

Any recommendations/models to avoid?
Thank you.

- The car does not come with a spare, or even space to carry a spare...

Had a few no-names but they all failed, though I've never had one of the recommended Ring things.

I use a "classic" Decathlon bicycle pump for routine top-ups. This works surprisingly well and was the cheapest model they did,

Cant have that,, so of course they no longer sell it. Now they do a lot of designery junk that doesn't work.

GF got me an extremely designery battery powered Xiaomi gizmo which charged via USB, so of course it now doesn't

For emergency use I have some little disposable CO2 cylinders, but have never used them. I also have a full sized spare.

Must get around to improvising something. Pop bottles, old fire extinguishers, fridge compressors are all candidates, The tricky bit is the valve connection. I favor screw-ons rather than push-ons for a more positive connection

I suspect you have plenty of time on your hands to mess around making a tyre pump lol, surely it would be easier to buy one, not being funny just seems a lot of work for a simple item ;)

<< I suspect in The Yook too >>

Now that you are not in Taiwan, Ed, might I most respectfully suggest that repeated use of your strange word 'Yook' is left behind while you are back here ? I have never seen or heard anyone else use it, and I know it has confused some in earlier years ?

I have an Einhell 18v cordless that runs off my drill batteries. As does the strimmer, the mower, the reciprocating saw, the sander, the vacuum, the leaf blower etc.

An update. Like others I was happy with my Ring basic 12v pump. Well it broke last week after over 10 years. It was running but not producing any pressure. I opened it up and I was pleasantly surprised to find that the pump unit was metal, possibly cast aluminium. So not plastic. Unfortunately the metal had fractured, allowing air out.
I don’t know why it fractured but apart from that it looked well made. Looking at reviews, cheap pumps are a lottery with a lot of early failures. So I’ve bought an apparently identical Ring for £12.50.

If I get another 10 plus years out of it at that price I will be happy.

I've a couple of 12V inflators, but I still find a MK1 leg on a double-barrel footpump the quickest (and I get a bit of exercise).
