Travel Adapter for Vietnam: Do You Need One? (Cuba → Vietnam)Adapter Needed

If you're heading to Vietnam from Cuba, sorting out the power situation is one of the easiest pre-trip wins. Below you'll find the plug types, voltage, and frequency used in Vietnam, whether you need an adapter, and which devices are safe to plug in.

Do you need a travel adapter for Vietnam?

Good news: you generally don't need a plug adapter. Both Cuba and Vietnam use Type A/C outlets, so your existing plugs should fit Vietnam's sockets directly. A universal adapter is still worth keeping in your bag as a backup for future trips.

What plugs and sockets does Vietnam use?

Vietnam uses these power plug types: Type A: two flat parallel pins (ungrounded), the standard North American and Japanese plug; Type C (Europlug): two round pins, ungrounded, and the most widely used plug across Europe; Type G: three rectangular pins with a built-in fuse, the British/Irish plug. Outlets run at 220V and 50Hz. Since Cuba also uses Type A/C, your plugs already match.

Voltage and frequency in Vietnam

Vietnam supplies 220V at 50Hz, which differs notably from the 110V used in Cuba. This matters most for single-voltage, high-wattage appliances such as hair dryers, straighteners, curling irons, and electric kettles. Plugging a 110V-only device into a 220V outlet can overheat or destroy it. Check each device's label: if it reads "INPUT: 100-240V" it handles both and you only need a plug adapter; if it lists a single voltage, bring a voltage converter or leave it home.

Will your devices work in Vietnam?

Phones, tablets, laptops, and camera chargers are nearly always dual-voltage (100-240V), so they work in Vietnam with just your existing plug, and no converter is required. The devices to watch are heat-based appliances: hair dryers, flat irons, and travel kettles are often single-voltage and can fail on Vietnam's 220V supply. Many travelers simply buy a dual-voltage travel version or rely on the hotel's hair dryer.

What travel adapter should you buy for Vietnam?

Because Cuba and Vietnam share Type A/C outlets, you don't need a special adapter for this trip. A universal travel adapter is still a smart, inexpensive backup if you plan to travel elsewhere, and the better ones add USB-C fast charging to free up your charger.

Tips for charging your devices in Vietnam

Pack at least one adapter per traveler, and consider a small power strip from home, which turns a single Vietnam outlet into several. Ordering online before you fly is almost always cheaper than airport kiosks.
