## Overview

The MXR Iso-Brick Power Supply is a compact, lightweight, and rugged power hub designed for pedalboards. It features 10 fully isolated outputs with varied voltage and current ratings—including adjustable outputs for vintage battery sag effects—ensuring noise-free, reliable power for both analog and digital pedals. Perfect for professionals seeking a clean, versatile, and gig-ready power solution.

## Description

The MXR Iso-Brick Power Supply is small and light with tons of quiet, noise-free DC power on tap ready to run a wide range of pedal types without crowding or weighing down your pedalboard. Each of the Iso-Brick Power Supply’s 10 outputs is fully isolated, eliminating gig-ending ground loop noise. Whether analog or digital, positive or negative ground, this power box has you covered. The MXR team broke down these 10 outputs to accommodate a variety of voltage and current requirements: two 9V outputs at 100mA, two 9V outputs at 300mA, two 9V outputs at 450mA, two 18V outputs at 250mA, and two variable outputs adjustable from 6V to 15V at 250mA. The two variable outputs can be used to emulate voltage “sag,” a drained battery effect sought by many vintage tonechasers. On top of all that, the Iso-Brick Power Supply comes in a small, lightweight housing that’s built like a tank. Features power on/off and connection status LEDs. Put this little box on your pedalboard to make sure it runs reliably and quietly gig after gig. • Pedalboard-friendly size • 10 fully-isolated outputs • Quiet, noise-free operation • Powers a wide range of pedal types—digital and analog, positive and negative ground • (2) 9V outputs @ 100mA, (2) 9V @ 300mA, (2) 9V @ 450mA, (2) 18V @ 250mA, and (2) variable outputs adjustable from 6V to 15V @ 250mA • Variable outputs can be used to emulate drained battery effect • On/off and connection status LEDs

Review: Great power supply - This power supply is perfect for my acoustic pedal board. All of the cables are included plus 1 extra “Y” cable to run from the power supply to 2 pedals. I use all 5 of the outputs and have no issues. It is quiet, tiny, and does not affect the sound of my guitar.
Review: Reliable - Amazing product. First purchased mine in 2018. Has been reliable for years 👍

### ⭐⭐⭐⭐⭐ 18V output for Eden WTDI
*by B***Y on December 18, 2025*

Works Great. Have it powering (4) 9v pedals and using the side output @18v to drive my Eden WTDI amplifier which eliminates a wall wart. Very small and fits under my Voodoo Labs Dingbat Small pedal board. Highly recommend.
