What plugs are used in different countries

Electrical plug shapes, mains voltage and frequency vary by destination. A plug adapter changes the physical connection; it does not itself convert voltage. Check the destination’s current guidance and your device’s input rating before travel or before specifying a charger for an export market.

Examples from destination authorities

• Japan: Type A outlets and 100 V supply. Eastern Japan uses 50 Hz; western Japan uses 60 Hz.
• Switzerland: Type C and Type J plugs, with 230 V / 50 Hz supply.

What to verify before choosing an adapter

• Confirm the socket type at the exact destination. Different countries, regions and older buildings may use different outlets.
• Read the input label on the charger or appliance. If the local voltage or frequency is outside its rated range, a simple plug adapter is not enough; use a suitable power supply or properly rated converter.
• Check grounding, plug fit and applicable local safety requirements. A plug that appears to fit is not proof that a device is safe to use.

For an OEM/ODM project, tell us the target countries, plug type, electrical input rating and certifications required so we can recommend a suitable design.
