The rated voltage of a product aligns with the standards of the country/region where it is sold. If this device is available in your area, it is suitable for use within the local electrical environment.

Note: It is advisable to verify the relevant specifications before making a purchase, as some sellers may source products from unofficial channels and offer devices from other countries that may not be compatible for use in your region. Additionally, when shopping online, you might come across devices sold by cross-border sellers.

To know what device is available in your region, check the local TP-Link official website. TP-Link Smart Switch
