OT - maybe - 12v USB hub

Spring the 5V from the Car PC psu.

[snip]

There is no car PC. The PC is 20 meters away down 4 active USB extension leads. There is a battery power pack with three cigar lighter sockets at the camera.

I've found a regulated psu at Maplin with a 5v output and a selection of connectors that will do the job:

I don't know how I missed it earlier in the week :-)

Been there, done that.

$75 carriage.

IDGAF. If you meant to type "and at pikey market prices" then you should say so.

I've got an Ipod travel charger. 3 parts in a box off a market stall.

1: A USB to Ipod cable reel adaptor, gave that away. 2: A 3 pin mains USB charger which with a pound land USB cable reel that has 5 adaptors has charged my MP3 player and phone in Prague and on a cruise. It's also charged my Niece's Creative Zen. 3: A car cig socket 5V charger USB rated at 1000mA.

About £10 the lot.

I think the car phone chargers poundland sell aren't well regulated.

800mA but label suggests volts can be all over the place.

Thanks for that Peter. I think I've seen that sort of thing but you can't pass data through the USB power socket. Before I got ill I'd have just made a regulator. It looks as though it's all a bit academic now. It appears the data rates are too high to share one USB 2.0 cable so I'll have to run two of them instead of using a hub. If the voltage drop is too high I'll just have to use two powered hubs.

It's for a camera and autoguider on a telescope and since it's powered by a 12v car battery in a case with cigar lighter (one of those jump start/portable power units) I thought someone may have come across a cig socket powered hub.
