12V Power Cable — 20 in

Connect 2.1 mm Power Outputs to 2.5 mm Pedal Inputs

The T-Rex 12V Power Cable is designed for compatible pedals that use a 2.5 mm power jack while the power supply uses a standard 2.1 mm connection.

The red cable makes it easy to identify among other pedalboard power cables.

How It Works

Connect the 2.1 mm barrel plug to a compatible power-supply output and the 2.5 mm barrel plug to the pedal’s power input.

The cable adapts the connector size required by the pedal.

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

Important: Verify the Pedal’s Power Requirements

A physically compatible connector does not automatically mean the electrical power is compatible.

Before connecting your pedal, always verify:

Voltage
AC or DC
Polarity
Current requirement

Use this cable only when the power-supply output matches the electrical requirements specified by the pedal manufacturer.

2.1 mm to 2.5 mm Connection

Many pedalboard power systems use a 2.1 mm barrel connection, while some effects require a larger 2.5 mm power jack.

The T-Rex 12V Power Cable provides the correct physical connection between those two sizes.

Power Budget

This cable changes the connector size, not the electrical characteristics of the power supply.

Whatever voltage, AC/DC type, polarity, and available current exists at the source is passed through to the pedal.

Always confirm that the source and pedal are electrically compatible before connecting power.
