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 pedal power supply
Count outputs and current first
The AZOR has 8 isolated outputs, the Yueyinpu has 7, the Voodoo Lab X4 has 4, and the Donner and STRICH each have 10. Current matters as much as count: the AZOR, Yueyinpu, and Donner mix 100mA, 300mA, and 500mA outputs, the STRICH mixes 100mA and 500mA, while the X4 gives 500mA on every output. Match each pedal to a port that meets its voltage and current before buying.
Match voltage to your pedals
The AZOR switches one output between 9V and 12V, the Donner and STRICH add 12V and 18V outputs, and the Yueyinpu and X4 run on 9V only. A pedal that needs 12V or 18V cannot run on a 9V-only port, so check each pedal voltage first. The X4 runs on 100-240VAC, which suits international touring.
Check size and mounting
The AZOR weighs 0.5 lb, the Yueyinpu weighs 0.8 lb, and the X4 weighs 0.2 lb, all in small bodies. The X4 mounts below low-profile pedalboards with 3M Dual Lock, and the Donner uses a sandblasted aluminum body. Measure your board space before buying, since the supply must fit beside your pedals.
