JOYO JJP04 Guitar Effects Pedal Power Supply - 10 Isolated Outputs, DC 9V/12V/18V, Aluminum Alloy, Black

Power your entire pedalboard with a single, robust unit that delivers up to 1400mA across 10 dedicated outputs. The JOYO JJP04 combines 9V, 12V, and 18V rails in a rugged aluminum alloy chassis, so every stompbox gets the clean, stable current it needs.

Overview

The JOYO JJP04 is a dedicated power supply for guitar effects pedals, offering a versatile combination of voltages and currents to accommodate a wide range of stompboxes. It includes seven 9V 100mA outputs for standard analog and digital pedals, one 9V 500mA high-current output for power-hungry multi-effects or loopers, one 12V 100mA output for pedals requiring higher voltage, and one 18V 100mA output for pedals that benefit from increased headroom. All outputs share a common ground (non-isolated) and feature center-negative polarity, the standard for most guitar pedals.

What stands out

• 10 outputs with mixed voltages: 9V, 12V, and 18V
• High-current 500mA output for demanding digital pedals
• Short-circuit protection on each output prevents damage
• Blue LED indicators for each output show status at a glance
• Durable aluminum alloy housing with passive cooling
• Includes 10 DC cables and AC adapter (100-240V input)
