In Vietnam, type A, C and D power outlets are used, while in Hong Kong, you use plugs G and D. If you're traveling to Vietnam, you'll need a power adapter for types A, C and D, as your power plugs won't fit the sockets there.
Since you'll need a travel adapter for Vietnam when coming from Hong Kong, we suggest opting for a universal power adapter that works in many countries and will also prepare you for future trips.
Make sure to get a power adapter for outlets of type A, C and D. If you often go abroad, consider getting an all-in-one adapter (most adapters even have additional charging ports for USB-A and USB-C). Since you also need an international power (voltage) converter to keep your devices protected (more info further down), getting a combo power adapter/converter might be the best solution.
Vietnam uses both 110 V and 220 V, with a frequency of 50 Hz. This means voltage levels can vary depending on your location, even between different accommodations. In Hong Kong, your devices are typically designed for a 220 V electrical system. To ensure you don’t damage your devices, always check the local voltage before use, and if it’s 110 V, use a converter.
A voltage converter keeps your electrical devices from Vietnam running properly by adjusting the power to the right voltage. Without it, your devices could overheat or get damaged from the wrong power supply. Since you need a travel adapter as well, a combo power (voltage) converter with adapter features might be a good choice.
To confirm, check if your devices require a voltage converter by looking at the 'INPUT' label, typically found on the power adapter or charger. If the label shows "INPUT: 100-240V, 50/60 Hz," the device is built to handle different voltage and frequency ranges, meaning you’ll only need a plug adapter for the outlets in Vietnam. This is typical for devices such as notebooks, smartphones, digital cameras, and also for tablets, e-readers, and some battery chargers.
In Vietnam's 110 V regions your hair dryer could malfunction as your hair dryer is designed for Vietnam's 220 V, so you will need a voltage converter. However, where Vietnam's outlets deliver 220 V, you won’t need a voltage converter, as both countries use compatible voltage (220 V and 220 V) and frequency (50 Hz) levels.
Yes, most laptops and smartphones support a wide voltage range (100-240V), so you can use them in Vietnam without a voltage converter. Since both countries use the same frequency (50 Hz), there’s no issue.
In Vietnam's 110 V regions you will need a voltage converter to prevent malfunction as your curling iron / hair straightener is designed for Vietnam's 220 V. However, where Vietnam's outlets deliver 220 V, no voltage converter is necessary. Since the frequency is the same (50 Hz), the device should function normally.
Yes, when traveling from Hong Kong, you will need a power adapter for type A, C and D power outlets in Vietnam.
In Vietnam's 110 V regions you will need a voltage converter, since your Hong Kong's device will typically support 220 V. In regions where 220 is used, a converter is not necessary. Since both countries use the same frequency (50 Hz), there won’t be issues related to frequency.
See if your power plugs from Hong Kong fit into the sockets of other destinations and whether you need a voltage converter.
