Bought this off SW. It seems to work great. I'm using it with a USB power brick to power my strobostomp mini (which I leave the display always on) without disturbing my pedalboard setup.
This is a simple cable--one end has a USB-A plug, the other has a 9V barrel plug to power a pedal. SW says this is good for 300ma. The strobostomp takes nowhere near that, so all good. I don't see why it couldn't take a splitter and power multiple pedals as long as the sum is under 300ma.
If you need pedal power somewhere that has a USB (or you bring a USB power brick) but doesn't have AC power, this may help. RECOMMENDED.
