JOYO Built-in 4400mAh Rechargeable Guitar Pedal Power Supply

In this review the JOYO Built-in 4400mAh Rechargeable Guitar Pedal Power Supply is evaluated for players who need a portable, multi-output solution for powering pedal boards. The single biggest reason to buy is its integrated 7.4V/4400mAh rechargeable battery that delivers hours of independent power without running mains cables. For gigging guitarists, buskers, or anyone building a compact board, the unit combines multiple isolated outputs with a USB charging option and an LED battery indicator, making it a practical rechargeable power hub.

Key Features

• Built-in rechargeable battery: The 7.4V/4400mAh pack charges in about 2.5 hrs and provides portable power when mains are unavailable.
• Flexible runtime: Expect roughly 2 hours with high current digital pedals and over 10 hours powering 8 analog pedals for extended practice or small gigs.
• Multiple DC outputs: Eight DC jacks include four 9V 100mA and three 9V 500mA outputs plus one adjustable 9V/12V/18V jack for diverse pedal needs.
• USB charging: A 5V/1A USB port can charge a phone or small tablet, useful for keeping mobile devices topped up on the road.
• LED indicators and lighting: A bright LED doubles as board lighting and a battery level indicator, and charging automatically stops when full.

Who It's For

The JOYO rechargeable power supply is best for gigging guitarists, hobbyists with compact pedal boards, and buskers who need a self-contained power source without access to wall power. Its mix of low-current and medium-current 9V outputs and the adjustable jack make it suitable for typical analog pedals and many lower-draw digital effects.

Players who rely on several very high-current modern digital pedals or multi-effect processors should look elsewhere for a supply with higher per-jack current capacity, or use the JOYO as a supplemental battery solution rather than the sole mains replacement.

Pros & Cons

Pros

• Long battery life with mainly analog pedals, offering true portability for practice and small shows.
• Combination of eight DC outputs and a USB port covers common pedal and device charging needs.
• Fast recharge time at about 2.5 hrs and automatic cut-off protects the battery.
• Bright LED is practical for pedal board visibility and monitoring battery level.

Cons

• Maximum current on the adjustable jack is limited to 100mA, which may not suit some pedals requiring higher draw.
• Some customers report occasional hum with certain pedals, so results can depend on pedal compatibility.

Our Verdict

The JOYO 4400mAh rechargeable pedal power supply is a sensible, cost-effective option for players who need portable, multi-output power and long runtimes with analog boards. It is good value for gigging musicians and hobbyists who prioritize portability and rechargeability, but those with many high-current digital pedals should confirm current requirements before relying on it as their only supply.
