Can AC power supply 120v China be used?
No, you can only use a transformer to reduce the voltage.
If the voltage is not enough, you can't use electrical appliances to supply power.
Because the electricity supply in China is 220 volts.
Suppose the resistance of the circuit is R, connected to 220V and power =220? /r ... exceeds the rated power.
Connect 120V, power = 120? /r ................ This is the rated power.
So the electrical equipment is damaged.
