10 Best Guitar Pedal Power Supply 2025 in the United States

The Donner DP-1 Guitar Power Supply is a practical choice for guitarists looking for a versatile and reliable power source for their pedals. It features 10 isolated outputs, which include seven 9V 100mA outputs, one 9V 500mA output, one 12V 100mA output, and one 18V 100mA output. This variety allows it to cater to a wide range of pedal requirements.

The inclusion of independent short-circuit protection ensures that if one output fails, the others will continue to function, providing added reliability during performances or practice sessions. The noise reduction circuit design is another notable feature, helping to minimize unwanted noise and ensuring a cleaner sound. With an aluminum alloy build, it is both lightweight and durable, making it easy to transport and resilient to damage. The compact size further adds to its portability, fitting comfortably on most pedalboards without taking up too much space.

The blue LED lights are not only functional, indicating power and short circuit status, but also offer a cool aesthetic. On the downside, some users might find the 100mA outputs insufficient for high-power pedals, and the fixed output voltages may limit flexibility for those with more specialized needs. Additionally, while the aluminum build is durable, it may not be as robust as some higher-end models made from more premium materials. Despite these minor drawbacks, the Donner DP-1 is a solid choice for guitarists needing a reliable and versatile power supply for their pedal setup.

The Voodoo Lab Pedal Power 2 Plus Isolated Power Supply is designed to meet the needs of guitarists with a variety of pedals on their pedalboard. It offers multiple outputs, which is great for supporting a range of pedals, including those from brands like Strymon, Eventide, and Boss Twin.

The output voltage of 240 volts and wattage of 200 watts ensure that it can handle high power requirements, making it suitable for more demanding setups. Isolation is one of the key features of this power supply, ensuring that each pedal receives clean and consistent power without interference, which is essential for high-quality sound.

The unit's size, at 11 x 9 x 2 inches, and weight of 3.08 pounds, make it relatively portable, though it's not the most compact option available. Build quality and durability are noteworthy, with many users praising its robustness and reliability. However, the product is battery-powered, which may not be ideal for all setups, especially for those who prefer a direct AC connection. This power supply is a solid choice for guitarists looking for reliable and isolated power for their pedals, but the size and battery-powered aspect may be a consideration for some users.
