Dickybeau Posted August 10, 2018 Share Posted August 10, 2018 I have the Fiat compressor that came with the van. It isn’t cheap but effective. Link to comment Share on other sites More sharing options...
Keithl Posted August 10, 2018 Share Posted August 10, 2018 Ring RAC900. Not the cheapest but very good quality and robust. PS It will not run off a cigar lighter socket and comes with crocodile clips to attach directly to your battery. Keith. Link to comment Share on other sites More sharing options...
Brock Posted August 10, 2018 Share Posted August 10, 2018 Same as Keith. Important to ensure you can reach all five tyres [or more] when it is clamped on the battery [i use the leisure battery]. Link to comment Share on other sites More sharing options...
Derek Uzzell Posted August 10, 2018 Share Posted August 10, 2018 weldted A similar question was asked here a fortnight ago and repeatedly in the past. http://forums.outandaboutlive.co.uk/forums/Motorhomes/Motorhome-Matters/12v-van-tyre-pump-recomendations-please-/49906/ It really depends on what you want and how you plan to use the pump. A manual bicycle ‘track pump’ will handle the 5.5bar/80psi pressure OK and should be fine if you just want raise the inflation pressure by a few psi - and the only power-source needed will be muscle-power. A reasonable-quality electric compressor powered from a vehicle’s 12V dashboard socket may cope satisfactorily with car-tyres that are not normally inflated above 3.0bar. But if a motorhome tyre has (say) a slow puncture and the pressure needs to be raised significantly, this will take a LONG time to do even if the pump proves capable of actually performing the task. High-output 12V compressors will rapidly inflate a motorhome tyre that’s seriously deflated, but such pumps aren’t cheap and their amperage demand will usually be too high to allow dashboard-socket operation. Any 12V pump aimed at inflating car tyres often has a power-cable that’s too short to reach all the wheels of a motorhome - it’s something to watch out for. There are also 230V mains-powered pumps/compressors, rechargeable pumps, and ‘jump-start packs’ with a tyre inflating capability. This 2018 AutoExpress article reviews 8 electric pumps. http://www.autoexpress.co.uk/accessories-tyres/89534/best-mini-air-compressors-for-car-tyres-2018-group-test The test involved raising the pressure of a 15” car tyre from 20psi to 30psi, but how well (and how quickly) the cheaper pumps would have coped inflating a 15” motorhome tyre from 70psi to 80psi is anybody’s guess. On paper, the Ring RAC 830 pump tested should cope - and should be fairly quick - but it draws a maximum of 15A, has an around-£65 asking-price and Amazon customer reviews are not confidence-inspiring. There are much better ‘motorhome suitable’ pumps in that price-bracket. Link to comment Share on other sites More sharing options...
weldted Posted August 10, 2018 Author Share Posted August 10, 2018 Many thanks for info, the one I have is a twin cylinder type, I got round the short power lead by fitting a longer air hose, this has to be connected directly to the battery as the amps are too great for a lighter socket. It's just it has now started to take ages for the last 10-15 psi and gets very hot. Only had it less than a year. As we are away for long periods I like to be able to check the tyres reguarly Link to comment Share on other sites More sharing options...

Works really well, and I have a 12v socket on a lead attached to the habitation battery, which can also be used for other 12v accessories.

Derek Uzzell Posted August 10, 2018 Share Posted August 10, 2018 weldted - 2018-08-10 11:05 AM Many thanks for info, the one I have is a twin cylinder type... Could you say which make/model of pump you currently have, please? There are plenty of twin-cylinder pumps being marketed on-line. Some of them have a very low asking-price (example here) https://www.ebay.co.uk/itm/HOT-12V-Car-Air-Pump-Compressor-2-Cylinder-4x4-4WD-Tyre-Inflator-85L-min-150PSI-/332286133691 and many of them are virtually identical except for the brand-name on the label. https://tinyurl.com/yd3wghus I bought the ‘basic’ T-Max BA2641 pump that’s mentioned here and the cheapest current UK asking-price may well be the one in this advert https://www.island-4x4.co.uk/tmax-compressor-72lpm-ba2641-p-3922.html There is an even more powerful version that looks similar but is normally a good deal more expensive, so it’s essential to confirm exactly which pump is being advertised when comparing prices.

weldted Posted August 10, 2018 Author Share Posted August 10, 2018 Hi eBay purchase brand was HOT, on second use the on off switch melted, swopped it with a heavier one, same thing happened. Now bypassed switch but it is now failing to inflate much above 4.5/4.7. To be fair it was only £26 and the seller refunded the full price no problem. Using this type you need to keep the engine running as the current draw is heavy. Link to comment Share on other sites More sharing options...
