This is a bit OT but I know you lot are a mine of info so here goes:
I've lost the transformer that came with my USB hub (where do these things get to?). Anyone know where I can get hold of a simple plug and go 6v 2.1amp with a standard large female pin connecter (I'm sure there's a technical term for this!), neg outer plus inner if this makes sense.
Something like
There are others with packs of different connectors if you prefer that, .andy

Eeh, them's called power supplies
Maplin?
Maplin - they've just started doing one, which they call a "digital camera power supply". Adjustable voltage, 15 quid.
They're hard to find. 2A is a lot of current, only old digicams and USB hubs need that much current, so you're unlikely to have an alternative to hand from something else.

....but *sometimes* they are nothing but a transformer!
This'll do the job:
Might not be on offer tomorrow though.
cheers, Pete.
True, but for USB hubs, little ethernet hubs and the like (at least all that I've seen), those that do need power supplies generally take a fairly heavy lump unregulated linear dc supply or a small switched one, regulated.........

Not if the output plug is marked 'neg outer' as in this case. It means it has a rectifier - and generally smoothing as well.
Very true - missed that bit!
About the only common thing I've come across that uses just a transformer (apart from some LV desk lights, etc) is for some reason external modems. These usually are supplied with AC - but I haven't a clue why.

Bargain of the month, a switcher, normally 20quid plus . . . . but do I _really_ need it . . . .
I have some Orange phone chargers...!
In american Wall Warts - I think this is a very appropriate description...
Go on, treat yourself ;) you might need it in a month or two...
I used one over summer to run a few cheap case fans to keep my face cool.
cheers, Pete
Shoving DC into a hub? I think not
I think the "neg" and the "plus" bits sort of give the game away, don't you?
Bit late there, Geoff...I admitted my blunder a while ago!
Yeah, I saw it just after I posted this
