Yuio 9V 1A Pedal Power Supply - Negative 5.5x2.1mm for BOSS & MXR

Power your pedalboard with confidence using the Yuio 9V 1A Pedal Power Supply. This compact AC/DC adapter converts any wall outlet (100-240V, 50/60Hz) into a clean 9V DC output, delivering reliable current to keep your effects sounding consistent night after night. The center-negative polarity (tip negative, sleeve positive) matches the standard of popular BOSS, MXR, Zoom, Behringer and many other brands, so you can replace batteries and eliminate unwanted noise caused by weak power sources. A 5.5 mm x 2.1 mm barrel connector and a 2 m (6.56 ft) cable give you flexibility to place the supply wherever it fits best on your rig. Designed for a wide range of pedals-including BOSS ME-80, PSA series, and similar models-the adapter supports both individual units and small chains, helping you keep your setup tidy and portable. With its durable construction and built-in safety features, this power supply protects your gear from voltage spikes while providing the steady power your creative performance demands. Whether you're playing a gig, rehearsing at home, or recording in the studio, the Yuio adapter ensures your pedals stay powered without the hassle of swapping batteries. Its universal 9V center-negative design also works with select keyboards and other devices that require the same voltage, expanding its usefulness beyond guitar effects. The low-profile plug and robust cable resist tangles and wear, making it ideal for touring musicians who need dependable gear day after day. By providing a steady voltage, the supply helps maintain the tonal integrity of your pedals, preventing the pitch wobble and dropout that can occur with aging batteries. Choose Yuio for a cost-effective, reliable power solution that lets you focus on playing, not on power management.
