- Voltage / frequency: 220V, 60 Hz
- Coming from the US: plug adapter needed — Some sockets. 220V vs US 120V: single-voltage US devices need a voltage converter or they will be damaged; most phone/laptop chargers are dual-voltage (100-240V) and only need a plug adapter for any round-pin (C) socket
Power plugs in United States

Power adapter FAQ
Is there a universal travel adapter that works everywhere?
Yes for the plug shape — a universal travel adapter handles the common plug types (A, C, G, I) in one unit. But a universal adapter does not convert voltage. If you carry a single-voltage US appliance into a 230V country, you still need a separate voltage converter.
How do I know if my device is dual-voltage?
Read the small print on the charger or device. If it says “INPUT: 100-240V, 50/60Hz” it is dual-voltage and safe worldwide with just a plug adapter. If it lists only “120V”, it is single-voltage and needs a converter abroad.
Which countries use the same plugs as the US?
Type A/B plugs at 120V/60Hz are standard across most of the Americas — Canada, Mexico and much of Central America — plus Japan (100V). US travelers usually need no adapter or converter there. Almost everywhere else needs at least a plug adapter.
