This guide covers the setup and operation of the D'Addario XPND Pedal Power Battery Kit. It provides instructions for powering your pedalboard via the included battery or an external USB power supply, along with critical safety and polarity information.
Powering with Battery
To power your pedalboard using the portable battery:
- Connect the Power Gateway to the portable power supply using the short USB-C cable (275mm).
- Connect the adjustable daisy chain to the Power Gateway and your pedals.
- Press and hold the power button on the battery to turn it on or off.
- When active, the battery will display the current charge level.
Powering with USB Power Supply
To power your pedalboard using an external USB charger:
- Connect the Power Gateway to a USB charger using the long USB-C cable (2m).
- Connect the adjustable daisy chain to the Power Gateway and your pedals.
- Ensure you are using a compatible USB charger.
Charging the Battery
To charge the portable power supply:
- Connect the portable power supply to a USB charger using the 2m USB-C cable.
- The battery will display the charge level during the process.
Important Safety and Polarity Information
Polarity is critical. The standard 5.5mm jack used on effects pedals must match the following configuration:
- Center pin (tip): Negative (ground)
- Outer barrel (sleeve): Positive (hot)
Connecting a tip-positive power supply to your system could cause permanent damage to your effects pedals. Do not exceed 1500mA total power draw. The device is intended for indoor use only. Do not attempt to open the adapter or battery. If you experience noise issues, especially when mixing analog and digital pedals, use the Pedal Noise Isolator (PW-XPNDPNI-01, sold separately) to provide galvanic isolation.
