My trusty old jump start pack which also has a tyre compressor died.
Didn't owe me anything as it had a lot of use as a compressor over the
years. But annoying in that I'd recently fitted a new battery - and it's
the gears between the motor and compressor which have stripped. Motor
still runs, so I'd guess the compressor seized.

One thing that annoyed about it was the useless pressure gauge.

So decided on a replacement. Inflator only, so a lot smaller. Bit like a
cordless drill. Vast range of models and prices on Ebay.

Went for a Blaupunkt. Three times the cost of the cheapest but has an 18v
2 amp.hr battery rather than the cheap ones which all seemed to be 12v 1
amp.hr. But not as expensive as so called 'garage' ones.

It works well - quicker than the old one - but the gauge is still poor.
About 25% out at 30 psi.

Is it really impossible to make a gauge which actually works?

In the handbook, they quote the spec. But not the accuracy of the gauge.
