Cioks CI-2201 Booster Flex Voltage Doubler

CI-2201 Booster Flex type 1 - voltage doubler, 50cm (black)

Booster Flex is a special Flex cable with a little step-up converter built-in on the middle of the cable which doubles the voltage. You should only use it with low current pedals which draw below 50mA, typically Wah pedals and drives. You can get 18V from a single 9V outlet or 24V of an outlet set to 12V.
