Can anyone recommend a tyre inflator that runs on both 12v DC and mains AC?

Only specs to duty cycle I can find, I have blown up a pair of flat weeks fergie trailer tyres which it did with ease but the cylinder does get hot .

 

Ring 12 Volt RAC900 Heavy Duty Air Compressor - Sheridan Marine

 

Heat is exactly why a mains unit should be used whenever possible

12v Units are made smaller to be portable so are not so good at heat dissapation which is a result of compressing the air

I'm too lazy!

 

 

That looks similar to the one in my first link. And some of the reviews did say that it blows the fuse in the cigarette lighter socket...

 

 

Cheers, will have a look.

 

Hi SANDS it blow fuse as it over 10amps power we one here 30amps great pump thanks Jon

My advice would be to look at the run times of these inflators and make sure you spend more than £50 on one. We have melted dozens of the cheapys over a period of time, I bought a load to chuck in the works trucks and the lot are knackered. I checked on the max run times afterwards and some are 3 minutes which is about enough time to pump up a barrow tyre.

Even the duty cycle on the Ring one is 20% so probably 5 minutes on and then 20 minutes off.

 

I found the cheap ones ok for car tyres, if short-lived as they have no lubrication. Not much cop at popping the bead back on a 13x34 tyre.

 

Over the years I tried many things, when I had a petrol landrover the shraeder spar plug thingy was best.

 

I even took the 150W compressor off an old fridge (naughty as this released freon into the atmosphere) and ran this of an inverter but you still needed to keep the engine running as 12A soon discharges the battery.

 

If one could find a continuous duty 12V compressor and only wanted to buy one why not have that and an 8A battery charger whilst using it from mains.

 

I have a scuba bottle, fully charged, which I inherited 6 years ago from an air rifle enthusiast. I was thinking about trying that to inflate tyres as it has a pressure reducer on it. I never have found out how much they cost to have refilled.

I have just looked in the user manual which says:

. It should not be used for continuously for more than 30 minutes. After 30 minutes turn off and let it cool for 15 minutes before resuming operation.

In my book thats pretty darn good for emergency jobs to get one out of the mire?

OK that's not too bad, I misinterpreted the meaning of 20% duty cycle which was in the advert.

Your interpretation of duty cycle is the same as mine, ie, 20% on and 80% off over a 10 minute period so figures in the ad must be wrong or they have a different interpretation of duty cycle to ours.?

When I was researching 12volt compressors I came across these with a 100% duty cycle but couldn't justify the cost.

some advert that is 1.17cfm at 0 psi I can fart better than that:biggrin:

Just bought this petrol mobile compressor for less than some of the leccy 12volt ones

 

It keeps up with a nut gun.
