No power cord but runs on 6 double A batteries, which I'll include to get you started. You can use a Boss 9v PSA.
The SPD6 MIDI percussion pad features 113 internal drum sounds, with six rubber playing pads and can run from an optional power adaptor or from batteries, with a life of up to 20 hours. A sensitivity switch allows it to be played with your hands or fingers, and it comes with 16 preset drum kits and 16 user kits. You can connect two footswitches to trigger an additional kick drum sound and to switch between open and closed hi‑hat settings.
