The iso4 is a compact 4-output, rechargeable lithium-ion pedalboard power supply built for guitarists who want pristine tone without being tethered to a wall outlet. Because it runs on battery power, your rig is completely free from AC power—and the 60Hz hum and ground noise that come with it.

Each output features patented BiWire™ isolation technology, separating both positive and negative ground paths so every jack behaves like its own dedicated power supply. The result? Dramatically reduced crosstalk, noise, and interference between pedals—so your tone stays clean, focused, and consistent.

Smart internal battery management continuously monitors current draw and charge level, calculating your exact remaining runtime based on your pedal load. You’ll always know how much power you have left, so there are no surprises in the middle of a gig or session. All vital status info is clearly shown on the built-in LED display.
