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 guitar pedal power supply
Count outputs before you count pedals
Start with how many pedals you power at once, then check the voltage and current each pedal needs. The Yueyinpu supply has 7 isolated outputs, the Hiree and Tavsou supplies have 10 isolated outputs each, and the Caline supply has 6 DC outputs. Match a pedal to a port with the same voltage, and keep its current draw at or below the port current, since the Yueyinpu, Hiree, Tavsou, and Caline ports include 500mA ports alongside 100mA ports. A pedal that needs 12V or 18V needs a supply with a 12V or 18V port, which the Hiree and Tavsou supplies provide.
Check short-circuit protection on each output
Separate short-circuit protection means a fault in one channel does not stop the other channels. The Yueyinpu, Hiree, and Tavsou supplies have separate short-circuit protection on each output, and the Caline supply has independent short-circuit protection. Indicator lights help find the fault channel: on the Yueyinpu, Hiree, and Tavsou supplies, the light for a short-circuit channel goes off while lights for other channels stay on. Compare that detail with the number of outputs and the voltage mix before you choose.
Match the plug and cord to your pedal
Check the plug size, tip polarity, and cord length before you buy. The JOYO adapter uses a 5.5mm by 2.1mm tip-negative plug with a 4.92ft cord, and the Caline supply uses a 5.5mm x 2.1mm center-negative DC connector. The Hiree supply uses a 5ft disconnectable AC power cord, and the Tavsou package holds 10 power cables and 2 polarity reversal cables. Count the cables in the package against the pedals you plan to power, so you have a cable for each pedal at setup.
Frequently asked questions
How many pedals can a small power supply run at once?
It depends on the output count. The Yueyinpu supply has 7 isolated outputs, the Hiree and Tavsou supplies have 10 isolated outputs each, and the Caline supply has 6 DC outputs. The JOYO adapter gives one 9V 500mA output, so it fits a one-pedal setup.
Do I need isolated outputs for guitar pedals?
Isolated outputs keep each channel separate, and separate short-circuit protection means a fault in one channel does not affect the other channels. The Yueyinpu, Hiree, and Tavsou supplies have isolated outputs with separate short-circuit protection. Check the output count and voltage mix against your pedals before you choose.
What voltage do guitar pedals need from a supply?
Pedals here use 9V power, and the Hiree and Tavsou supplies also have 12V and 18V outputs. Match the pedal voltage to a port with the same voltage, and keep the pedal current at or below the port current. The Yueyinpu, Hiree, Tavsou, and Caline supplies include 500mA ports alongside 100mA ports.
What cables come with a pedal power supply?
It varies by supply. The Yueyinpu package holds 7 power cables, the Tavsou package holds 10 power cables and 2 polarity reversal cables, and the Caline package holds an adapter and 6 cables. The Hiree supply has a 5ft disconnectable AC power cord. Count the cables against your pedals before you buy.
