Voodoo Lab Pedal Power Cable PPBAT-R

I bought this to power a Harley Benton MiniStomp with a 9V battery when playing over a Bose S1 in a mobile setting with no wall power. Works fine if I use a polarity inverter cable in between, i.e. this thing has minus outside, not inside as advertised. Probably a quality issue with production, at least one other reviewer had the same observation.

Excellent option for those vintage pedals or old Tuners that don't have external power sockets. Simply click on to your devices battery clip and you are good to go with noiseless power to your device.
