Tyre Inflator Compressors

I have a nice portable Ring RAC620 tyre inflator which I always carry with me on trips in order to reinflate the car tyres to towing pressures having reduced the same upon arrival at the campsite and before commencing daily trips out. The only drawback is that this pump is 12V and runs off the cars cigarette lighter socket which provides enough amps for it to run but has no dual voltage capability in order for it to be run off the mains supply when attached the EHU or when in my garage etc.

I've tried connecting it up to my coolbox 230V > 12V converter but it doesn't supply anywhere near enough amps output for it to run the tyre inflator.

Does anyone know of/heard of a suitable converter (144 Watts, 12V) to give sufficient amps output to run this tyre inflator or, failing that, know of a dual 230V AC/ 12V DC portable tyre compressor of suitable physical size to still make it truly portable and worth carrying?

There's this one which claims to run a Ring RAC 600/RAC 640 inflator Alan :- http://www.amazon.co.uk/Operate-RAC600-R...s/dp/B00PUNIGOY (currently out of stock but also on Ebay) but it's only up to 120W? Also it's got a UK plug on it and not a Euro Plug
By the way, our Eriba has a cigarette lighter socket just inside the door.

So has ours but it blew the fuse when I tried to inflate the caravan tyres using my Ring RAC620 inflator.

Serves you right, you idle bugger.

What's wrong with a footpump? It's good exercise.

Well for tyre inflation purposes having a cigarette lighter socket in the caravan isn't much different to using the one I already have in the car. But thanks for the other link - as you say though, the output doesn't really match.

It is if your caravan is connected to the EHU.
So the Ring RAC 620 is more powerful than the RAC 600 or the RAC 640?

You really ought to concentrate on using both legs equally as your current lack of symmetry in the calf department is not only disturbing to behold but could explain the difficulties you experience when trying to walk in a straight line.

I don't understand the relevance of being connected to EHU, Roger, as the supply to the cigarette lighter sockets will still be 12v (from the battery which is topped-up via the transformer) and limited by the load rating of the fuses fitted to protect the circuits.

I've just checked and my compressor (a Ring 630 by the way) is rated at 10 amps. The cigar lighter sockets in my car are protected by 15 amp fuses and can therefore cope with the load. The 12v sockets in the Eriba (in the strip light fittings and the separate socket in the cabinet side), however, are protected by 7.5 amp fuses and will, as I discovered, blow if used to inflate tyres.

I also checked my CTek Multi 7000 charger which has a 'supply mode' to see if this might provide an alternative solution but it too is limited to 7 amps.

Sorry, Roger, rush of blood and all that.

I have the RAC700compressor which on the side states: 12v, max 12amp, 144Watts, .

Looking at the RAC automotive site nothing is stated for either the 600 or 640 in terms of Power (wattage) but both state a maximum of 10amps which must rate them about the 120watts mark I would guess

Either way, all the models require more than 1amp which is what my Coolbox transformer supplies and which barely turns over the tyre compressor let alone supply any air.

Not sure what the point is that you're trying to make regarding the 12v cigarette lighter connection in your caravan. What's important is the amps supplied from the socket and even the 12v socket in my Touran will not supply the output necessary unless I have the engine running.

PS - just looking at my RAC700 I see that it has an in-line fuse that is rated at 15amps.

Perhaps I misunderstood your question but when you suggested that you wanted a mains adaptor for the EHU when you're on the camp site I though it was to save the drain on your car battery.
The caravan battery will re charge when the van is plugged in the the EHU and it's often easier to use the on board cigarette outlet rather than the car outlet to do the tyres on the van. I don't know what the output is on the compressor I use but the van supply is more than adequate.
Of course, it always pays to have your engine running when you use a compressor on the car battery.
So, I'm baffled as to why you want a mains compressor when you are on a camp site.
I was looking at the rate of air output on the Ring 600, 620 and 640 as I couldn't see a wattage figure quoted and the 600 and 640 appear to give a larger rate of air output than the 620 so I assumed they were more powerful.

See what you've gone and got me to do now? I've had to go out to the car and try and get a rating off my tyre compressor without any success.
The only indication is on a sticky label that states it's an Argos MK 9. I've had it and used it successfully for about 10 years. Plug it into the cigarette socket on the side of the sink unit which is immediately inside the door and it's in easy reach of the door side tyre. Run it through the wash room window and it'll do the other side as well.

Amps, watts, volts, fuses - phooey.

Here's your alternative solution...

A few weeks blowing up your tyres with one of those babies and your calves will be so shapely that Mrs Cauldron will be chasing you round the greenhouse.

As I mentioned in my first post, Roger, it would also be nice if I could use the compressor in our underground garage when at home and prior to a trip etc. Use of the compressor plugged into the cars cigarette lighter socket entails having the engine running and in a confined space like our underground is not what you would call desirable.
On site of course, having the engine running is no big deal but if I could find a small portable tyre compressor that was able to run off both 230V AC and 12V DC then not only would I be able to use it in the underground garage but also on site running from the EHU or other extension cable running from it with cigarette lighter socket serving as a backup.
From what my research throws up, however, is that no small, portable and dual powered tyre compressor exists, and finding a 230V AC to 12V DC converter with sufficient guts (amps) equally as hard.
