Just arrived in Vietnam with chargers and appliances from home? Read this before you plug anything in.

Voltage and frequency

Vietnam uses 220V at 50Hz. That's the most important number on this page.

Socket types

Most sockets in Vietnam accept two-pin plugs, both flat and round pins. Some newer buildings also have other socket types. If your plugs are UK-style (three square pins) or Australian-style, you'll need an adapter.

Adapter or converter?

Check the small print on your charger or device:

• It says 100–240V: you only need a plug adapter. Most phone and laptop chargers are like this.
• It says 110–120V only: an adapter is not enough. Some hair dryers, kettles and appliances from the US or Japan are 110V only. You'd need a voltage converter, or it's often simpler and safer to buy a local one.

A plug adapter changes the plug shape. It does not change the voltage.

Protect your electronics

Power cuts and surges happen, especially during storms. A power strip with surge protection is a good idea for laptops, monitors and TVs.

Quick checklist

• [ ] Check every device label for "100–240V"
• [ ] Universal plug adapter (2–3 pieces if you have many devices)
• [ ] Surge-protected power strip for expensive electronics
• [ ] Leave 110V-only appliances at home, or buy local
