The Seaboard RISE is primarily USB-powered. An internal battery, which is charged by USB, makes it possible to perform without a power connection by MIDI-over-Bluetooth. To charge the RISE simply connect it via the included USB cable to a computer's USB-A port or other similar USB-A charger.

External power supplies with an input voltage of 100–240V AC and an output voltage of 9–12V DC 18W center pin positive can be used. The measurements for the DC power input are: 4mm (outside diameter), 1.7mm (internal diameter), 11mm shaft length. An external power supply is not provided with the RISE.
