How we ranked these pedal power supplies
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.
- Outputs weight 2
- Isolated outputs weight 2
- Max current per output weight 1
Buying advice: small pedalboard power supply
Count the outputs you need
Outputs decide how many pedals one supply runs. The Donner DP-3, the RVONE board, the RVONE supply, and the STRICH supply give 10 outputs each, while the Coda adapter gives one regulated 9V output with an optional 5 way daisy chain. Count your pedals, check the voltage each pedal needs, and pick the output count that covers the whole board.
Match voltage and current per pedal
Voltage and current decide whether a pedal runs safely on an output. The Donner DP-3 gives 9V at 100mA, 300mA, and 500mA, plus 12V and 18V at 100mA. The STRICH supply gives 9V at 100mA and 500mA, plus 12V and 18V at 100mA. The Coda adapter gives 9V at 1700mA for one pedal. Match the voltage first, then check that the output current covers the pedal draw.
Use isolation and protection on stage
Isolated outputs keep one pedal fault from stopping the rest. The Donner DP-3, the RVONE board, the RVONE supply, and the STRICH supply give isolated outputs, and the STRICH supply keeps running if one channel short-circuits. The RVONE supply adds short-circuit protection, and the Coda adapter uses a ferrite magnetic ring for noise reduction. Put the supply on the board, plug each pedal into its own output, and check the indicator lights before you play.
Frequently asked questions
How many pedals can one supply power?
Count the outputs. The Donner DP-3, the RVONE board, the RVONE supply, and the STRICH supply give 10 outputs each, while the Coda adapter gives one 9V output with an optional 5 way daisy chain.
Do I need 12V or 18V outputs?
Check what your pedals need. The Donner DP-3, the RVONE supply, and the STRICH supply give 12V and 18V outputs alongside 9V outputs, while the Coda adapter gives 9V only.
What does an isolated output do?
An isolated output gives one pedal its own voltage path, so a fault on one output leaves the other outputs running. The Donner DP-3, the RVONE board, the RVONE supply, and the STRICH supply all give isolated outputs.
Can a supply charge my phone?
The RVONE supply has a USB output to charge a phone, alongside its 10 outputs for 9V, 12V, and 18V pedals.
