Vitoos USB-DC USB to DC cable
Product Description
This cable can be used to convert USB 5V DC to 2.1mm DC plug. This is specifically designed for use with products like Vitoos ISO4SE that converts 5V signal to 9V that can be used for pedals. Note: this will not work for pedals if you plug directly from a USB Source.
WARNING: Please do not plug this directly to 9v pedals as they may be under powered.
