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

Buying advice: guitar pedal power supply with USB
What isolated outputs mean for pedals
An isolated output gives each pedal its own power path, so a fault or noise on one output does not reach the others. The Hiree station gives 10 isolated outputs, the GHOSTFIRE GP8-SV2 gives 8, the Caline CP-209 gives 4, and the JOYO JP-05 gives 8 DC outputs. Each output on the Hiree station and the GHOSTFIRE supply has its own short-circuit protection, so one shorted cable does not shut down the whole board. Count your pedals first, then pick a supply with at least that many outputs.
How to match voltage and current needs
Match each pedal to an output with the right voltage and enough current. The Hiree station covers 9V, 12V and 18V, the GHOSTFIRE supply adjusts 2 outputs across 9V, 12V, 15V and 18V, and the JOYO JP-05 gives one adjustable 9V, 12V and 18V output. Check current too: the Hiree station gives 100mA on most outputs with one 500mA port, while the GHOSTFIRE supply gives 500mA on its 9V outputs and the Caline CP-209 gives 500mA per output. A digital pedal that draws more current than its output gives will not run right, so check the pedal draw before you buy.
USB ports and battery power on boards
A USB port on a power supply charges a phone or a small device while you play. The GHOSTFIRE supply gives a 5V 1A USB output, the Caline CP-209 gives a Type-C output, and the JOYO JP-05 gives a 5V/1A USB port. Battery power cuts the cord to the wall: the JOYO JP-05 runs on its built-in 4400mAh battery for more than 10 hours with 8 analog pedals, and about 2 hours with high current digital pedals. If the board stays near an outlet, an AC-powered supply like the Hiree station covers more pedals in one unit.
