JOYO Pedal Power Supply Rechargeable with 8 Isolated Outputs

In this review of the JOYO JP-05 pedal power supply the bottom line is simple: it is a practical, portable option for guitarists who need clean, isolated power on a pedalboard without running mains leads. The unit's biggest selling point is the rechargeable battery with multiple isolated outputs and a USB jack, which together let a player run a mix of analog and digital pedals for rehearsal or short gigs without a bulky power brick. For players who value silence and flexibility, this review finds the JP-05 delivers useful features in a compact package.

Key Features

• 8 isolated outputs: Provides independent filtered circuits so each pedal gets clean power and short-circuit issues only affect the relevant output.
• Switchable voltage output: One output can be set to 9V, 12V or 18V to match stompboxes that require alternate voltages.
• Rechargeable battery: The built-in 7.4V/4400mAh battery offers portable use and fast charging so the board can be used away from mains power for rehearsals or busking.
• Mixed current ratings: Includes 4 x 9V 100mA and 3 x 9V 500mA outputs to support both low-current analog pedals and higher-demand digital units.
• USB charging port: A 5V USB jack lets you top up a phone or tablet from the pedalboard battery while performing or traveling.

Who It's For

The JP-05 suits gigging guitarists and hobbyists who build compact pedalboards and need an all-in-one rechargeable power solution with multiple isolated outputs. It is especially useful for players who mix a few digital pedals with analog fuzzes or delays and who appreciate low noise from the power supply.

Players who require very long battery runtime for extended outdoor sets or who need more than one adjustable high-current 12V/18V rails should look at larger mains-powered supplies instead. Likewise, those who never play away from a venue with reliable mains power might prefer a permanent board-mounted adapter.

Pros & Cons

Pros

• Multiple isolated outputs keep noise low and prevent a single short from killing the whole board.
• Rechargeable 4400mAh battery makes the unit genuinely portable for rehearsals and short gigs.
• Combination of 100mA and 500mA outputs covers both classic analog pedals and many modern digital effects.
• USB port adds convenient device charging without a separate power pack.

Cons

• Battery life is mixed in reports, so heavy use with many digital pedals may need backup power or frequent recharges.
• Only one adjustable voltage output is provided, which limits flexible multi-voltage setups simultaneously.

Our Verdict

The JOYO JP-05 is a sensible value option for players who want a compact, rechargeable pedalboard power supply with isolated outputs and a USB charging option. Its mix of 100mA and 500mA outputs and noiseless operation make it good for mixed analog and digital rigs, though those needing extended runtime or multiple adjustable voltage rails should consider larger alternatives. For short gigs, practice and portable setups it represents strong value.

Frequently Asked Questions

How long does the battery last?
The 7.4V/4400mAh battery gives at least a couple of hours on a full charge and can extend to many hours with mostly low-current analog pedals, though user reports vary depending on pedal draw.

Can it run high-current digital pedals?
Yes, three outputs are rated at 9V/500mA for higher-demand digital pedals, and the isolated circuits help keep noise low when several pedals are connected.

What happens if an output shorts?
Each output has its own LED and independent protection, so a short will turn off only the affected output light while the other outputs continue to work.
