Tyre Pump

Try this:

12v Extender

Had the same problem and this solved it.

👍

I use the caravan 12v socket and thread the wire through the window nearest to the tyre needing air. 

Lucky you don't blow the fuse!

This looks quite well made but it only has a 5A Fuse which the Ring compressor may well blow.

Also the wire is 20awg which is just about suited to the fuse. That is probably why one of the reviews said the cable was melted and the fuse blown.

I made one, for a coolbox but same components. You need the 10a version and 2.00mm2 cable. Easy to buy parts as long as you get the decent quality ones (unfused) and add an inline 10A blade fuse. Brass or Nickel finshed ones are usually better quality.

I could easily reach with cable supplied going through the windows.

Alternatively I just carry a footpump now, electric one was a faf to use!

Have a look on EBay, loads of choice on there.

The extenders don’t work and they do blow the fuse.

i bought a machine mart cordless tyre compressor for about £50. Has a battery and doubles as a lamp and jump starter. Was not impressed. Took ages to inflate anything and the hose has now cracked as it folds inside the lamp housing, oh and not accurate.

i bought the Ring RAC high pressure compressor. Good bit of kit. Has a very long hose, all brass connectors and hooks up to your battery and comes in a nice bag. Well worth the money.

No cable required 😉

Beg to differ. We've had a 4.5 metre 12volt extension lead for the last 5 years or so & never blown a single fuse.

Ditto but for 8 years, I have never thought to check the rating because I have never had a problem with it. I always run the engine when inflating tyres.
