- You want fewer than 10 isolated outputs
- You want more than 2 polarity reversal cables
The supply gives 10 isolated outputs: 6 at 9V and 100mA, 2 at 9V and 500mA, and 1 each at 12V and 18V at 100mA. All 10 outputs have separate short-circuit protection, and the blue LED for a short-circuit channel goes off while the other channels stay on. The box holds 10 power cables and 2 polarity reversal cables, and the supply uses a DC 18V input with the adapter provided.
4Also Great
GOKKO Guitar Pedal Board with Built-in Power
- Isolated outputs not stated in the listing
- Max current per output not stated in the listing
It holds Also Great as a board with a built-in supply, 8 outputs at 9V, and a carry bag at 15 inches by 5 inches.
Who it suits
- Players who want a board and supply in one purchase
- Players who run 4 to 6 pedals on one board
Skip it if
- You want more than 8 outputs on a supply
- You want a board longer than 15 inches
The board measures 15 inches by 5 inches by 2 inches and holds 4 to 6 pedals, with the supply hidden inside. All 8 outputs run at 9V, 2 are high current for newer high power effects, and every output is short-circuit protected, filtered, and regulated. The box holds the board, an AC adapter, DC cables, Velcro tapes, and a carry bag, and the board sits at about 8 degrees.
5Also Great
pigtone DC 9V1A Guitar Pedal Power Supply
- Isolated outputs not stated in the listing
- Max current per output: 1000 mA
- 1-year warranty stated
It holds Also Great with a DC 9V adapter at up to 1000mA and a 5-way daisy chain for 5 pedals.
Who it suits
- Players who want one adapter for 5 pedals
- Players who run pedals from 10mA to 1000mA
Skip it if
- You want more than 5 pedals on one adapter
- You want an output above 9V
The adapter takes AC 100V to 240V at 50/60 Hz and gives DC 9V at up to 1000mA, with a center negative plug of 5.5x2.1mm. The 5-way daisy chain cable powers 5 pedals at once, for pedals drawing from 10mA to 1000mA. It uses noise reduction and isolation safety protection, and it carries a 1-year warranty.

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: pedalboard power supply
Match outputs to your pedal count
Output count decides how many pedals one supply runs. The Donner DP-3, the Mosky supply, and the Tavsou supply each give 10 isolated outputs, while the GOKKO board gives 8 outputs at 9V and the pigtone adapter runs 5 pedals on a daisy chain. Count your pedals first, then pick a supply with at least that many outputs.
Check voltage and current per output
Voltage and current must fit each pedal. The Donner DP-3 gives 9V, 12V, and 18V outputs, the Mosky supply gives 2 adjustable outputs at 9V, 12V, or 18V at 500mA, and the Tavsou supply gives 6 outputs at 9V and 100mA plus 2 at 9V and 500mA. Read the current each pedal needs, then match it to an output that gives at least that current.
Check protection and indicator lights
Protection keeps one fault from stopping the whole board. The Mosky supply and the Tavsou supply give separate short-circuit protection on each channel, so a short circuit in one channel leaves the other channels working. The Mosky supply and the Tavsou supply also give an LED indicator on each output, which goes off on the short-circuit channel. The GOKKO board gives short-circuit protection on all 8 outputs as well.
Frequently asked questions
How many pedals can one power supply run?
It depends on the outputs. The Donner DP-3, the Mosky supply, and the Tavsou supply each give 10 isolated outputs, the GOKKO board gives 8 outputs at 9V, and the pigtone adapter runs 5 pedals on a daisy chain. Count your pedals, then match the count to a supply.
Do I need isolated outputs for my pedals?
Isolated outputs keep each channel apart. The Donner DP-3, the Mosky supply, and the Tavsou supply each give 10 isolated outputs, so a short circuit in one channel leaves the other channels working. The pigtone adapter uses a daisy chain instead, which shares one output across 5 pedals.
What voltages do pedal power supplies give?
Several supplies here give 9V, 12V, and 18V. The Donner DP-3 gives 9V, 12V, and 18V outputs, the Mosky supply gives 2 adjustable outputs at 9V, 12V, or 18V at 500mA, and the Tavsou supply gives 12V and 18V outputs as well. The pigtone adapter gives 9V only.
