Daisy chains? Guitar 77 has Visual Sound OneSpot daisy chains in two models, 5 or 8 outputs. Generous amounts of cable.
Godlyke (forget which shop has) daisy chain, I think 11 outputs, slightly shorter. The plugs seems to hold better on some of my pedals' power jacks, but on other pedals it sticks out more. I still prefer the OneSpot daisy chains.
TYMC has daisy chains too, dunno what brand.
Single male/male or male/female cables, no idea. Try Sim Lim Tower?
