Stoker Elektrek is equipped with a 2.1 mm hollow connector to supply power to effect pedals. A short adapter cable is included. The module itself draws power from the modular PSU. A look at the other technical data reveals that Stoker Elektrek is compatible with many effect pedals:

9V DC power supply
Up to 750 mA
Polarity: peak = negative / ring = positive

On top of that, Stoker Elektrek offers two mini multiples, each with one signal input and two outputs, which can also be used as a large splitter.
