Can anybody lend me a Powerbook G4/iBook G4 charger?

["Matthew Walton" <matthew alledora co uk>]

I very very stupidly left mine at home (scatterbrained really, I also
forgot my razor and a few other things much less important than my
laptop's sole source of sweet delicious power). I was wondering if anybody
could be kind enough to lend me theirs so I can get a bit of a battery
top-up. My laptop's a 12" G4 Powerbook, but I think it's compatible with
the entire modern G4 Powerbook line (the aluminium ones) and also the
iBook G4 chargers look the same.
If you are such a kind soul, I'm in Robert Love's talk later, then in the
Keynote, Panel Applets, Lightning Talks, Topaz planning tomorrow. Or just
wander about looking for me, at the moment I'm in List-Saal opposite
König-Karl-Halle.
