JOYO JP-912 9V 1.2A Guitar Pedal Power Supply with 5-Way Daisy Chain

The five-way daisy-chain format lets one JOYO power supply serve a group of guitar or bass pedals. Its 9V DC output delivers up to 1.2A, and the centre-negative design suits pedals that use this common connection. The included reverse-polarity cable adds another connection option for compatible pedals.

Product specs

• Output: 9V DC, 1.2A, 10.8W
• Polarity: Centre negative (tip negative)
• Barrel size: 5.5 × 2.1 mm
• Input: AC 100–240V, 50–60Hz, 0.6A
• Compatibility: Most 9V centre-negative guitar effect pedals
• Adapter cord: 1.5 m

The five-way chain can power up to five pedals at once from a single adapter, helping keep a pedalboard’s power setup organized. When planning the chain, match each pedal’s voltage and polarity to the supply and ensure the combined current requirements fit within the adapter’s 1.2A output. The noise-reduction circuit and low-impedance pure copper wire are designed to support a quieter playing setup, while built-in protection features include short-circuit, overcurrent, overheat and overload protection.

Getting the most from it

Connect the adapter to the daisy-chain cable, then connect compatible pedals to the chain. This arrangement is useful for a rehearsal or home setup where several effects need power without a separate adapter for each one. Before connecting a pedal, check that it requires 9V DC with centre-negative polarity and a 5.5 × 2.1 mm barrel connection. Use the supplied reverse-polarity cable only where its polarity conversion matches the pedal’s requirements.

A shared daisy chain is a practical alternative to powering each pedal with its own adapter: it brings several compatible connections together in one setup. Customer feedback is positive on compatibility and power, while comments on noise level are mixed, so the noise-reduction design should be understood as a feature rather than a guarantee of silence in every rig.

Box contents

The package includes the JOYO 9V DC, 1.2A power adapter, one five-way daisy-chain cable and one reverse-polarity cable. Together, these provide the main supply and connection options for building a compatible multi-pedal setup.

When it makes sense

It suits you if you want to power several 9V centre-negative guitar or bass effects from one adapter and prefer a shared cable layout over separate power supplies. The five-way chain is the key benefit for a compact pedalboard, while the reverse-polarity cable provides added flexibility for a compatible pedal connection. With its 1.2A output and clearly defined barrel size and polarity, the JOYO JP-912 is a useful fit for organizing power across a group of supported effects.
