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.

Buying advice: bass pedal power supply
Count outputs and current first
Outputs decide how many pedals run at once. The JOYO JP-02 gives 10 isolated outputs, the STRICH SPS-40B gives 10 independent 9V outputs, and the pigtone 1to8 adapter powers 8 pedals from one adapter. Current matters too: the STRICH outputs give 300mA on 2 ports and 100mA on 8 ports, while the JOYO JP-02 gives 500mA on one 9V port. Match each pedal to an output with enough current before you buy.
Choose isolated or daisy chain power
Isolated outputs keep each pedal on its own output. The JOYO JP-02 has 10 isolated outputs with short-circuit protection on each output, and the STRICH SPS-40B has 10 isolated ports. Daisy chain cables share one adapter across pedals: the pigtone 1to8 cable powers 8 pedals, and the JOYO 5-way cable powers 5 pedals. If one pedal causes noise on a shared chain, an isolated supply separates it.
Check voltage and polarity before buying
Voltage and polarity decide whether an adapter fits a pedal. The JOYO JP-02 covers 9V, 12V and 18V, while the other four supplies give 9V. The pigtone adapters use a center-negative design, and the JOYO 1.2A adapter uses a tip-negative design. Check the voltage and the polarity on each pedal before you buy, since a wrong match will not power the pedal.
Frequently asked questions
How many pedals can the JOYO JP-02 power?
The JP-02 gives 10 isolated outputs, so it powers 10 pedals with one output per pedal.
What is the difference between isolated and daisy chain power?
Isolated outputs give each pedal its own output, while a daisy chain cable shares one adapter across pedals. The JP-02 and the SPS-40B use isolated outputs, and the pigtone 1to8 cable powers 8 pedals from one adapter.
Can the STRICH supply run without an outlet?
Yes. The SPS-40B runs on a 10000mAh battery for 10+ hours of cord-free power, so no wall outlet is needed during use.
Which adapters include a daisy chain cable?
The pigtone 1to8 adapter includes a 1to8 way daisy chain cable, and the JOYO 1.2A adapter includes a 5-way daisy chain cable.
