How we ranked these pedal power supplies
Every pick ranks in Amazon's best-seller list for its category and has 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: pedal power supply for home
Count isolated outputs and voltages first
Isolated outputs give each pedal its own power feed, so one pedal does not share a ground with another. Count how many pedals need 9V, how many need 12V and how many need 18V, then match those counts to the port list. The Mosky, LEKATO, Caline and Donner supplies have short-circuit protection per output, so a fault on one output does not stop the other outputs. A supply with more outputs than pedals leaves room for a pedal added later.
Match current per output to each pedal
Current is measured in milliamps. A 100mA output suits a pedal that draws 100mA or less, while a 500mA output covers pedals that draw more. The Caline supply has outputs at 100mA, 300mA and 500mA, and the Mosky and LEKATO supplies have outputs at 300mA and 500mA. Check the current figure for a pedal, then pick outputs that meet it.
Plan the board, the cables and the outlet
Put the supply where its outputs reach the pedals without stretching cables, and keep the USB port free if a phone needs charging. The Voodoo Lab supply has a 200-watt AC outlet for an additional device, so a device that needs AC power can share the board power. The Mosky and LEKATO supplies have a USB port for charging a phone. Count outputs before buying cables, since a pedal without a free output cannot run.
Frequently asked questions
How many isolated outputs do I need for a home pedalboard?
Count the pedals on the board, then add the voltages they need. The Mosky and LEKATO supplies have 10 isolated outputs, the Caline supply has 12, and the Voodoo Lab supply has 8. Match the port list to the pedals, including any 12V or 18V pedals.
What does an adjustable output do on a pedal power supply?
An adjustable output switches between voltages, so one output can feed a 9V pedal, a 12V pedal or an 18V pedal. The Mosky and LEKATO supplies have 2 adjustable outputs at 500mA. Set the output to the voltage the pedal needs before connecting it.
Do I need a USB port on a pedal power supply?
A USB port charges a phone or tablet at the board. The Mosky supply has a USB port for charging mobile phones and tablets, and the LEKATO supply has a USB port for charging a phone. Compare outputs first, then use the USB port as an extra if a device needs charging.
What warranty comes with these pedal power supplies?
The Voodoo Lab supply carries a 5-year warranty, and the LEKATO and Donner supplies carry a 1-year warranty. Compare warranty terms alongside outputs and voltages when choosing.
