Traveling from South Korea to Vietnam?

✅ No Adapter Needed (Directly Compatible)

Plugs from South Korea plug directly into wall sockets in Vietnam, and mains voltage is compatible (220V vs 220V). Still verify that your high-power appliances support 220V. Electrical frequency also differs (60Hz vs 50Hz). Modern digital chargers are dual-frequency (50/60Hz), but analog motor-driven clocks or clippers may run slightly faster or slower.

Do I Need a Voltage Converter or Step-Down Transformer?

Look at your device power brick or label:

  • Dual Voltage (100V–240V, 50/60Hz): Found on virtually all modern smartphones, MacBooks, iPads, camera chargers, and laptops. You only need a simple physical plug adapter; no heavy voltage converter is required.
  • Single Voltage (110V–120V only or 220V–240V only): Frequently found on high-draw heating appliances like hair dryers, curling wands, electric kettles, and blenders. Plugging a 110V appliance into a 230V socket without a step-down transformer will destroy the appliance and trip breakers.
Frequently Asked Questions (FAQ)
Can I use my South Korea phone charger in Vietnam?

Yes. Phone chargers are universal dual-voltage (100-240V). If the plug prongs do not match, a standard travel plug adapter is all you need.

Are sockets in Vietnam grounded?

Vietnam uses Type A, C. Look for 3-pin adapters if your appliance uses a grounded plug.
