Cioks Booster Flex type 1 Cable - 50 cm
With Booster Flex it's easy to make 18V from a single 9V outlet. It's equipped with a step-up converter in the mould placed in the middle of the cable. When you connect the Booster Flex to a 9V outlet, you'll obtain 18V on the other end, which is a type 1 plug - a black 5.5/2.1mm centre negative DC-plug. The most common application is for 18V Wah pedals or the bigger MXR pedals needing 18V. Remember that the maximum current the Booster Flex can deliver is 50mA.
