Rechargeable Tyre Pump

RomfordNavy

Anyone found a good quality but not extortionally expensive rechargeable tyre inflator?  There seems to be a lot of crap out there some of which don't have enough battery capacity to inflate more than one tyre.  Any suggeations

Ring does an RTC2000 charger that seems quite well regarded, but I don't see figures for run time. It's pretty small since it fits in a bicycle water bottle cage.

You are trading portability for capacity, and running a compressor at higher pressures is quite a drain on battery so I'm not sure you'd get one that could completely inflate 4 car tyres from empty on a single charge. But they should all be able to top up a few car tyres by a few psi.

How much air do you need to get into how many of what kind of tyre?

Try a traditional pump and your left or right leg.

Always charged and ready to go, good exercise too !

Thanks for the suggestion.  Look up the specs for that but they don't reveal the battery capacity antwhere so I suspect that might be limited.  I note that they suggest it can "Inflate" bike tyres but only "Top-up" car tyres.

If you have got quite a big tyre which is very flat it can take absolutely ages.  Reason I am looking for a rechargeable one is because yet another traditional footpump has failed again, none of them seem to last more that five minutes.

Any reason you want a rechargeable one?  There are dozens and dozens of cheap 'n' cheerful electric pumps available that plug into the cigarette lighter.  I take your point about it taking a long time to inflate a completely flat tyre - but realistically, how often do you need to do that?  I've got an electric pump that came with the car (no spare tyre, one of those stupid cans of gunk and a compressor, grrrr), and use it very occasionally.  But for routine topping-up, and for bike tyres etc., an ordinary foot pump is far easier.

Letting a big tyre get "very flat" will very possibly damage that tyre too....

I had a rechargeable pump from Halfords, but it didn't las 5 minutes. The battery packed up first, which in hindsight would have done eventually unless it was used and charged regularly, but you don't expect to be having to use it regularly anyway unless you have a problem tyre.
Got away with using it wired to the cigarette lighter socket in the car for a short time, but then the gauge, then the compressor packed up, so I've reverted back to the old foot pump

How often do you have a big tyre go very flat? Buy a decent footpump and it should last considerably more than 5 minutes. Or, as suggested, get a 12V pump that runs off the car battery. 
I had a hybrid car with 2 "leaky" alloy wheels so I purchased a 12V pump plus a mains adapter so that I could top up the tyres at home without putting a 10A load on the very small Battery that hybrids have due to there being no traditional starter motor or alternator.

That doesn't seem unreasonable, since with bike tyres it's quite likely to need to inflate from empty (changing a tube for instance) but you're almost certainly not going to need to inflate a car tyre from empty because you can't just change a tyre at the side of the road. Adding the battery capacity to allow you to inflate 4 car tyres from nothing will stretch the definition of portable and no-one would be willing to pay for it.

I've got a 12V car powered charger that cost I think £5, and a cigarette lighter extension cable so I can each all of the tyres from the same socket. It's pretty basic and seriously noisy but it's worked fine for years.

I have had to change trailer tyres from 30 to 65psi and that took ages with a compressor, but I can't see why I'd need to do that with a battery powered unit.

Exactly how do they fail?
