I went to use mine earlier and its fuse blew
it had a 20A (yellow) blade fuse but I only had one with an LED fitted that tells you (helpfully) its blown
the replacement did exactly the same actually
and that was with compressor not attached to tyre initially, applied it to valve and it too blew after a couple of seconds.
Just had a quick scan for similar on net and see reference to 30A green which seems high to me but thought I'd ask what anyone else was using before setting something on fire
