9V Battery Clip Cable — 20 in

Power Battery-Operated Pedals from Your Pedalboard Supply

The T-Rex 9V Battery Clip Cable lets you connect compatible pedals that normally operate from a 9V battery to an external pedalboard power supply.

It is a simple solution for older or specialty pedals that do not provide a conventional external power jack.

How It Works

Connect the 2.1 mm barrel plug to a compatible power-supply output, then connect the 9V battery clip to the pedal’s battery connector in place of a standard 9V battery.

The cable allows the pedal to receive power from your pedalboard supply rather than relying on a disposable battery.

For Battery-Only Pedals

Some effects pedals—particularly older designs—were built primarily around internal 9V battery operation and may not include an external DC power jack.

The Battery Clip Cable provides a practical way to integrate those pedals into a modern powered pedalboard.

Important: Check the Pedal’s Power Requirements

The cable provides a physical connection to the pedal’s battery terminal.

It does not regulate or convert the power supplied by the power source.

Before connecting your pedal, verify:

Voltage
AC or DC
Polarity
Current requirement

Use the cable only with pedals whose electrical requirements are compatible with the power-supply output being used.

Power Budget

A 9V battery connection does not automatically mean that every 9V power source is appropriate.

Confirm that the power supply provides the correct electrical characteristics for the pedal and has sufficient available current.

The Battery Clip Cable simply replaces the physical battery connection—it does not change the power being delivered.
