The Cioks Four is a compact multi-effects power supply that can be used as a supplement to the Cioks DC7 power supply or as a stand-alone power supply for small pedalboards. The four isolated DC outputs provide selectable voltages between 9 Volts and 18 Volts, so almost any effects pedal can be powered. In addition, the Cioks Four is also flexible when it comes to its own power supply. The power supply accepts not only DC voltages between 9 V and 24 V or AC voltages between 9 V and 12 V, but also 5 V via USB-C.
