This product adapts to 12V, but it needs adding base feedbAack resistor to 150 ohm-1.5K ohm; its resistance should be adjusted from high to low but cannot be too low, or it will burn triode or the product; it also cannot be too high, or it will influence output effect or make triode overheating in non-operation state (15kV is max output, and limit output shouldn't be over 15kV, that is 1.5cm arc, or it will destroy the product).
