JOYO’s CM25 daisy chain cables can be used to supply power to more than one guitar effect pedal, removes the need for 4 x 9v power supplies using the same polarity. All the plugs of these series have undergone pure copper electroplating treatment and the core of the power cable is a pure copper conductor and will fit most guitar effect pedals requiring a 5.5mm jack.
These cables are suitable for heavy current or low current effect pedals. Just make sure that your main supply has enough Mah to power the pedals you attach.. A 9v DC supply operating at 800mah, will power 4 x 200mah pedals, a simple calculation. Connect your main supply to the female and let electricity do the rest..
