I have just purchased a 12v tyre inflator .The only trouble is it don't reach the rear tyres.I have a cigar adaptor extension that has a 5 amp fuse,which will enable me to reach the rear tyres .can I put a 10 amp fuse in place of the 5amp .
My wife says i dont listen to her...........I think thats what she said.
My first thoughts are that while you are at it, why not replace the whole cable without the need for a join, fitting the 10amp component from the original plug or even fit one in-line.
You can then rig a thick enough extension to reach the furthest tyre.
I too have a digital pump like Lifestyle, it will reach the front van tyres but not the rear so I bought a 10a extension. Used it several time ok but when I used it a couple of weeks ago the 10a fuse in the extension blew.
