The Synthrotek Power Pak converts the power in your Eurorack case to 9V, 12v, and 5V USB. You can easily power guitar pedals, drum machines, controllers, USB lights, charge smart phones, and other devices without having to lug around bulky power bricks. Just plug a male-male connector cable, daisy-chain cable or USB cable into the Power Pak, and you’re good to go.

Need to add +5V to your existing power supply? By installing one jumper, the Power Pak allows you to add +5V to your power distribution board or bus cable. This can be used to power Eurorack modules that need +5V. 

Keep it simple and tidy with the Synthrotek Power Pak!
