note:
Because the frequency is too high, the heat of the MOSFET will be relatively large. Please pay attention to the temperature of the heat sink when using, so as to avoid high temperature (mainly music modes) damage components.
During use, please do not place explosives items within 5m/16.4ft.
Due to the serious interference with the metal. Please do not approach the coils of electronic devices such as cell phones and computers to avoid damage.
Because the diameter of the secondary coil is very small, try not to bumpto avoid damage to the secondary coil winding
Please do not modify the equipment without permission to avoid accidents.
Do not use illegally.
For viewing only, if you do not know usage, please do not open it yourself.
