MXRM239 Mini Iso-Brick Isolated Power Supply

Independent shopping perspective
The Korena take
MXR’s Mini Iso-Brick is a compact pedalboard power supply with five isolated DC outputs. Four deliver 9V at 300mA, while the higher-current output switches between 9V and 18V at 800mA. Isolation is intended to remove ground-loop noise, and the supply handles both positive- and negative-ground pedals. LEDs make connection checks easier in dim venues. A supplied splitter can run two same-voltage pedals from one output when their combined current draw stays within that output’s rating.
Strong match
Who this is for
- Downsized travel boards that need isolated power without taking up much board space.
- Small pedal selections needing four 9V outputs plus one selectable 9V or 18V output.
- Dark-stage troubleshooting where illuminated connection-status indicators are useful.
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Selectable 9V/18V output at 800mA
One output can be set for either voltage and provides more current than the four 300mA outputs.
Detail 03
Included splitter cable
It can connect two pedals to one output if they use the same voltage and remain within its current rating.
Final check
Know before you order
- 01Confirm each pedal’s voltage and current requirements before sharing an output with the supplied splitter cable.
- 02The splitter is for two pedals requiring the same voltage; their combined current draw cannot exceed that output’s rating.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How many pedals can it power directly?
It has five isolated outputs: four 9V/300mA outputs and one selectable 9V or 18V/800mA output.
02Can the included splitter power two pedals?
Yes, when both pedals require the same voltage and their combined current draw stays within the selected output’s rating.
