Power Cable Help!

Beexter

Does anyone know where I can get a DC power splitter cable in the UK with 1x male 2.1mm jack on one end and 2 x female jacks on the other? Basically, just like the Voodoo Labs Output splitter but without the ground lift. Seems that everyone does the 1 female to 2 male but not the other way around..

+++EDIT+++ - just had a thought, admittedly maybe a dumb one but a thought nonetheless!........with the splitters that have 1x female to 2 x male 2.1mm plugs (ie. the ones you can get everywhere), if I plugged one of the male plugs into an outlet on a Voodoo Labs ISO5 and the other male plug into a pedal, would that provide power to the pedal and still leave power available at the female socket if I needed it? Or does the power have to come "in" to the female socket? No idea how these things work!
