The voltage needed depends entirely on the country or region where the plug is used. Here's why:
* Electrical Standards: Different countries have different electrical standards for voltage, frequency, and plug types.
* Appliance Compatibility: The voltage requirement is determined by the appliance plugged into the outlet, not the plug itself.
Here are some examples:
* North America (US, Canada, etc.): 120 volts
* Europe (EU, UK, etc.): 230 volts
* Japan: 100 volts
Important Note: Using an appliance designed for one voltage in a different voltage region can damage the appliance or cause electrical hazards. Always check the voltage requirements of your appliances and use appropriate adapters or transformers if needed.
