the sssnake DC3 Cable

Daisy chain is not the best solution for some electrical configurations, but when conditions are ok it's very practical. I had a power supply with limited outputs and bought this to introduce new pedals, I used it to power the lowest powered analog pedals (<30 mA) and it didn't produce any noise hiss or hum. The female barrel has a nice tight fit and is compatible with any standard centre negative 2.1mm barrel plug from most pedal power supplies.
I would't recommend it to power multiple digital and power hungry devices above 200 mA, but maybe you can get away with it.
