The 5 picks, ranked
1Best Overall
GHOSTFIRE Pedal Power Supply TRUELY Isolated
- Isolated outputs
- Max current per output: 300 mA
- 3-month warranty stated
It earns Best Overall with five fully isolated outputs, including one adjustable 9V, 12V or 18V output for pedals with different voltage needs.
Who it suits
- Beginners building a pedalboard with up to 5 pedals
- Players who need one adjustable 9V, 12V or 18V output

4Also Great
Pigtone DC 9V Guitar Pedal Power Supply
- Max current per output: 1000 mA
It earns Also Great with 9V at up to 1000mA for pedals drawing from 10mA to 1000mA, plus a magnetic ring that further reduces noise.
Who it suits
- Players with pedals drawing 10mA to 1000mA
- Beginners who want a 9V center-negative adapter
Skip it if
- You need an adjustable 12V or 18V output
- You need more than 1000 mA from one output
The adapter takes AC 100V-240V at 50/60 Hz and gives DC 9V at 1A with a center negative and external positive design. The DC plug measures 5.5 by 2.1 mm, and the adapter cable measures 110 cm, or 43 inches. Intelligent IC chips give noise reduction and isolation safety protection performance, and the magnetic ring at the end of the cable further reduces noise. It can pair with a daisy chain cable to power multiple pedals at the same time.
5Also Great
Pigtone Guitar Pedal Power Supply Adapter 9V
- Max current per output not stated in the listing
It earns Also Great with a 3-way daisy chain cable that powers up to 3 pedals at the same time from one 9V adapter.
Who it suits
- Beginners powering up to 3 pedals from one adapter
- Players with 9V tip-negative pedals and keyboards
Skip it if
- You need an adjustable 12V or 18V output
- You need to power 4 pedals at the same time
The 9V adapter comes with a 3-way daisy chain cable that powers up to 3 pedals at the same time, so one power source covers a chain without batteries. High-quality copper core cables with an anti-hum design give a quiet pedal chain condition and noise isolation. The adapter takes AC 100-240V at 50-60Hz and gives 9V DC at 1A for tip-negative pedals and keyboards.

How we ranked these pedal power supplies
Every pick ranks in Amazon's best-seller list for its category and has 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.

Buying advice: pedal power supply for beginners
Count your pedals before you choose
Start with how many pedals need power at the same time. The GHOSTFIRE unit has 5 outputs, the JOYO daisy chain adapter powers 4 pedals at the same time, and the Pigtone 3-way cable powers up to 3 pedals at the same time. A single adapter suits a setup with one pedal and keeps the board wiring simple. Count the pedals you own now, and leave room for the next pedal you plan to add, so the supply you buy still fits after the board grows.
Match voltage and current to each pedal
Voltage and current decide whether a supply fits a pedal. Four of the GHOSTFIRE outputs give 9V, and the fifth adjusts across 9V, 12V and 18V, while the other four supplies give 9V only. Current limits differ too: 300mA per GHOSTFIRE output, 500mA from the JOYO single adapter, 800mA with a 1A maximum from the JOYO daisy chain adapter, and 1000mA from the two Pigtone adapters. Check the voltage and current each pedal needs, then pick a supply whose outputs cover those figures.
Check the cable and plug size first
Plug size and cord length decide whether a supply fits your board layout. The JOYO single adapter and the Pigtone 1A adapter use a 5.5 by 2.1 mm plug, so check that size against your pedals before buying. Cord lengths differ: 4.92 ft on the JOYO single adapter, 8.8 ft on the JOYO daisy chain cable, and 110 cm, or 43 inches, on the Pigtone 1A adapter. The GHOSTFIRE unit measures 3.2 inches by 3.2 inches by 1.0 inches and weighs 0.6 lb, so measure the space on your board before choosing it.
Frequently asked questions
Can one supply power several pedals at once?
Yes. The GHOSTFIRE unit has 5 outputs, the JOYO daisy chain adapter powers 4 pedals at the same time, and the Pigtone 3-way cable powers up to 3 pedals at the same time. Match the pedal count to the output count before buying.
What does an adjustable output do for a beginner?
The fifth GHOSTFIRE output adjusts across 9V, 12V and 18V, so one output can serve pedals with different voltage needs. The other four supplies give 9V only, so a pedal that needs 12V or 18V needs the adjustable output.
Why does tip polarity matter for pedals?
Pedals expect a set polarity, and a mismatch can stop a pedal from working. The JOYO single adapter and the Pigtone 3-way cable use a tip negative design, while the JOYO daisy chain adapter and the Pigtone 1A adapter use a center negative design. Check the polarity each pedal needs before buying.
Do I need isolated outputs for a first board?
Isolated outputs keep each output separate, so trouble on one output does not disturb the others. The GHOSTFIRE unit has fully isolated outputs with short circuit protection on each circuit. The JOYO daisy chain adapter and the Pigtone 1A adapter use IC chips for noise reduction and isolation protection performance.
