When Ojai units are linked together, how many pedals can I power?

This depends on the current draw of the connected pedals.  Ojai can power 5 outputs at 9V with a full 500mA load.  Most pedals consume far less than 500mA, so this means that we can link Ojai and Ojai R30 units together and still have current available to power more than 5 pedals.

The included 24V power adapter (PS-124) provides a maximum of 24 watts of power. A likely scenario would be to link 2 or 3 Ojai or Ojai R30 units together, powering a combination of 10-15 high and low current draw pedals.  When linked to a Strymon Zuma power supply, you can link as many as 6 Ojai units to power up to 39 effect pedals.  When linked to a Strymon Zuma R300 power supply, you can link as many as 5 Ojai units to power up to 30 effect pedals.
