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: mini pedalboard power supply
Count outputs before counting pedals
Output count decides how many pedals run at once without a daisy chain. The RVONE board and the JOYO JP-02 hold 10 outputs each, the JOYO JP-05 holds 8, the GOKKO holds 6, and the Caline holds 4. Count your pedals first, then pick a supply with at least that many outputs.
Match voltage and current to each pedal
Voltage and current decide whether a pedal runs right: a 9V pedal needs a 9V output, and a high current pedal needs enough milliamps. The JOYO JP-02 mixes 9V, 12V and 18V outputs, while the JOYO JP-05 adds an adjustable 9V, 12V and 18V output jack. The Caline gives 500mA on each of its 4 outputs, and the GOKKO splits its 6 outputs across 100mA, 300mA and 500mA.
Decide between battery and wall power
Battery power frees a mini board from the wall outlet, while corded supplies run without recharging. The JOYO JP-05 runs on a built-in 4400mAh battery pack that charges in about 2.5 hours and lasts more than 10 hours with 8 analog pedals. The JOYO JP-02 runs on corded electric power, and the RVONE board uses a built-in supply. Pick battery power for cable-free setups and corded power for fixed boards.
Frequently asked questions
How many outputs does a mini pedalboard supply need?
It depends on your pedal count: the Caline holds 4 outputs, the GOKKO holds 6, the JOYO JP-05 holds 8, and the RVONE board and JOYO JP-02 hold 10 each. Count your pedals first, then pick a supply with at least that many outputs.
What is an isolated output on a pedal power supply?
An isolated output has its own channel, so a fault on one output leaves the others running. The RVONE supply gives 10 isolated DC channels, and each Caline output is fully isolated from the others.
Can a pedal power supply run on battery power?
Yes, the JOYO JP-05 runs on a built-in 7.4V and 4400mAh battery pack. It charges in about 2.5 hours and lasts more than 10 hours with 8 analog pedals.
Does the Caline supply charge phones through Type-C?
Yes, its Type-C output charges mobile phones, audio interfaces and wireless guitar systems. It also serves as a portable power supply for various devices.
