By using two isolated outlets this series adapter Flex gives you the sum of voltages of the two isolated outlets used. This adapter cable should be used in combination with any of CIOKS standard Flex cables if want to power an 18V or 24V pedal.

It gives you not only the higher voltage but also the possibility to choose the type of plug at the pedal end plus the length you need. The plug type and length are determined by the standard Flex cable used with the adapter Flex. If you’re looking for a simpler way to power an 18V pedal with a standard 5.5/2.1mm center negative DC-plug (BOSS standard) please have a look at CIOKS Stack Flex.

Note:

the series adapter Flex makes a series connection between the two outlets used. These two outlets must be isolated from each other. You get the sum of voltages and not the current (mA). If you use it with two 9V outlets with a 100mA rating each you’ll get 18V and still a max.

The current of 100mA. If you use it with two 9V outlets with 200mA each you’ll get 18V and max. 200mA. If you use it with two outlets rated to max. 200mA set to 12V you’ll get 24V and still max. 200mA.
