Mosky Guitar Pedal Power Supply 10 Isolated DC Output - Quiet

In this review the Mosky Guitar Pedal Power Supply is examined for players who build compact pedalboards and need reliable, low-noise power. The bottom line: it delivers a flexible mix of isolated outputs and a USB port in a compact aluminum case, making it a strong choice for hobbyists and gigging musicians who want separate protection per channel and switchable voltages for a few specialty pedals. The standout reason to buy is the combination of ten isolated outputs with short-circuit protection that keeps one faulty pedal from killing the whole board.

Key Features

• Ten isolated outputs: Seven 9V 300mA ports, one 9V 500mA port and two switchable 9/12/18V 500mA ports give power where most pedals need it without shared ground noise.
• Per-channel protection: Each output has short-circuit and over-current protection so a problem on one pedal will not shut down the rest of the board.
• Low noise design: Built-in noise filter and denoising chip reduce hum and keep the signal chain cleaner than many non-isolated supplies.
• USB charging port: A 5V/1A USB output lets you charge a phone or small device from the same unit, useful on stage or in the studio.
• Compact, heat-dissipating build: Aluminum alloy housing and internal layout support heat dissipation and make the unit portable for smaller boards.

Who It's For

The Mosky ISO 10 is aimed at guitarists and bassists with mid-size pedalboards who need multiple isolated outputs and occasional higher voltages for boost or octave pedals. Its compact 17.2 x 7.0 x 3.2cm footprint and 320g weight suit players who want a take-anywhere supply that still separates grounds to reduce noise.

Players relying on boutique pedals with unusual power demands or who need extremely quiet studio-grade supplies might look elsewhere, since reports of mixed noise performance and compatibility with some pedals suggest testing your specific gear before committing for critical recording work.

Pros & Cons

Pros

• Wide mix of isolated outputs including two switchable 9/12/18V ports for versatile pedal support.
• Independent short-circuit and over-current protection keeps other pedals running if one fails.
• Compact, lightweight aluminum design fits neatly under many pedalboards and dissipates heat well.
• Built-in USB 5V/1A port adds useful device charging without extra adapters.

Cons

• Noise performance is generally good but reported as mixed by some users, so compatibility with sensitive pedals can vary.
• One or two pedals may not operate correctly for some users; confirm voltages and current needs before relying on it for specialty pedals.

Our Verdict

The Mosky Guitar Pedal Power Supply is a practical, value-minded option for players who need multiple isolated outputs and built-in protection. It balances size, versatility and thermal design well, making it a good buy for gigging musicians and pedalboard hobbyists; anyone using noise-sensitive or unusual-voltage boutique pedals should test compatibility first.

Frequently Asked Questions

Can this power supply run vintage-style pedals that need 12V or 18V?
Yes, two outputs are switchable between 9V, 12V and 18V at 500mA, suitable for many pedals that require higher voltages.

Will a shorted pedal take down all my effects?
No, each channel has its own short-circuit and over-current protection so a single fault generally will not affect other outputs.

Is the unit quiet enough for recording?
It includes a noise filter and denoising chip and is quiet for many users, but some report mixed results with certain pedals, so audition with your setup if low-noise recording is critical.
