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: guitar pedal power supply
Isolated outputs or daisy chain
Isolated outputs give each pedal its own power circuit, so a fault on one output does not stop the others. The JOYO JP-02 and the Voodoo Lab X8 have isolated outputs. A daisy chain shares one adapter across several pedals, which costs less wiring and fewer boxes. The pigtone adapters and the JOYO DC adapter use daisy chains.
Count pedals and check current
Count the pedals on the board first, then match the supply to that count. The JP-02 has 10 outputs, the X8 has eight outputs, and the daisy chain adapters power five or eight pedals at once. Check each pedal's current draw against the output it plugs into, since a pedal that draws more than its output gives will not run right.
Check voltage and plug polarity
Most pedals here run on 9V, but the JP-02 also has 12V and 18V outputs for pedals that need them. Plug polarity matters too: the pigtone adapters are center negative and the JOYO DC adapter is tip negative, so a pedal that needs that polarity fits. A reverse polarity cable helps when a pedal needs the opposite polarity.
Frequently asked questions
Do I need isolated outputs for my pedals?
Isolated outputs give each pedal its own circuit, so a fault on one output does not stop the others. The JP-02 and the X8 have isolated outputs.
How many pedals can a daisy chain power?
It depends on the chain. The pigtone 5-way chain and the JOYO DC chain power five pedals, and the pigtone 1to8 chain powers eight pedals.
What voltage do guitar pedals use?
Most pedals here use 9V. The JP-02 also has 12V and 18V outputs for pedals that need a higher voltage.
Does a daisy chain adapter work with bass pedals?
Yes, if the voltage and polarity match. The JOYO DC adapter is made for bass guitar effect pedals, and the pigtone 8-way adapter is compatible with bass pedals.
