I think it's rare to find a power supply with 22 outputs at 500mA, so it could be useful for those who have large pedalboards or are using multiple power supplies to save space. Since this size isn't often available even used, those who want to buy it a little cheaper should definitely consider it. Here's the description from the website: The Canvas Power 22 has 22 independent power outputs that provide clean 9V power at up to 500mA. Two of these are variable voltage, allowing you to switch between 9V, 12V, and 18V to power high-voltage pedals. It also includes a USB-C port for powering devices such as smartphones and tablets while you play. ●SPEC ・SIZE: 41.7(W) × 2.6(H) × 5.4(D)cm ・WEIGHT: 572g ・9VDC 500mA output ×20 ・9-12-18V switchable output (9V-500mA/12V-375mA/18V-250mA) ×2 ・USB-C charging output ×1 In addition to the main unit, the original box and dedicated power cable are included.
