Battery powered tyre inflator

Anyone recommend a battery powered tyre inflator suitable for a motorhome...

Are you interested in a tyre inflator that is powered from a 12-volt source (eg. a motorhome's starter or leisure battery) or a 'cordless' inflator of the type tested in this article?

The only discussion I can find on this forum that mentions cordless tyre inflators was this 2022 thread.

This MHFun forum thread may also be worth reading.

A GOOGLE-search on "motorhome" "cordless" tyre inflators will identify plenty of possibilities, but it is evident that some of these are unlikely to cope effectively with the high pressures most motorhome tyres are inflated to. It's also worth checking that adverts for cordless inflators that have a removable battery actually include the battery in the asking-price.

As motorhomes will generally have large-capacity starter and leisure 12V batteries, most owners will choose an inflator powered from one of those batteries rather than the cordless variety. The RING RAC900 inflator mentioned above has proved popular (and performed well in a MMM Magazine test) though I opted for the T-Max product shown here.

Ryobi markets several cordless inflators that use the 18V ONE+ battery

https://uk.ryobitools.eu/power-tools/inflators-and-compressors-1/

and there's a review of the Ryobi R18PI-0 inflator in the AutoExpress article I gave a link to earlier. 

There are also several relatively inexpensive inflators similar in appearance to the Xiaomi product Seth77 mentioned.

It all depends on what people want...

I wanted, if necessary, to be able to rapidly pump up a seriously deflated motorhome tyre to (say) 70psi. I have a number of 12V-powered inflators that will happily put 5psi in a car tyre to increase its pressure from 30psi to 35psi (though not quickly). However, none of those inflators can pump up a motorhome tyre from 30psi to 70psi - they just can't handle the high pressure.

I have a Ryobi One+ tyre inflator. It will top up a motorhome tyre from say 60 to 65 psi, but it takes several minutes, and causes my hand to ache from gripping the trigger. If you wanted to inflate a MH tyres from flat, it would take some time.

It is better for car tyres around 30 psi or so.

I have an RAC900 which I carry in the van. A really good portable tyre inflator that handles my MH tyres with ease.

I use a Osaaer it looks like a power drill got it on Amazon for about £45 two years ago. Use it mainly for blowing up the tyres on our 2 electric bikes but it also gets used on the van with no problems getting 16 inch tyres up to 80 PSI. It's used a USB cable to recharge and the battery lasts for a very long time. We are more than happy with it ,used today as had the fourth puncture on the bikes this trip and not happy with that but the Osaaer makes light work unlike manual pump.
