This adapter converts DC9V to DC18V (or DC12V to DC24V).
It can power the effectors of 18V (or 24V) power consumption up to 100mA via the AC adapter with a common 9V (or 12V) voltage over TVD.
Ideal for those who want to add an AC adapter or power supply with only 9V output to 18V devices.
Red plug is output side.
Note: Please make sure that the device you use is DC18V (or DC24V), and the current consumption is less than 100mA.
If used on non-compatible devices will damage the device and adapter.
