Vietnam plug type and voltage: charging on the road
Round prongs, 220 volts, the adapter to pack and the power bank rules.
By the Local SIM Vietnam team, checked October 2, 2026
The short answer
Vietnam runs on 220 volts at 50 Hz, and most sockets take plugs with two round pins, sold as the type C shape. A phone or laptop charger rated 100 to 240 volts works as it is; only the plug shape may need an adapter, and travellers from the UK, the US and Australia should pack one.
- Voltage: 220 volts at 50 Hz.
- Sockets: most take plugs with two round prongs.
- Chargers: the 100 to 240 volt kind need an adapter, not a converter.
- Power banks: cabin bag only, at most two per passenger, up to 100 Wh without approval.

Good to know (Packing)
Power banks in the air
From 1 July 2026, Vietnam's aviation authority allows at most two power banks per passenger, in the cabin bag only, up to 100 Wh each; from 100 to 160 Wh the airline must approve before the flight.
No charging in the air
During the flight a power bank cannot charge another device, and cannot be recharged itself. Charge the phone fully before boarding; the power bank waits.
Single-voltage devices
Hair dryers and other devices built for 110 to 120 volts need a converter, not just a plug adapter. If the label shows one voltage only, leave it at home.

Do I need a voltage converter in Vietnam?
Not for a phone or laptop charger rated 100 to 240 volts. Vietnam's supply is 220 volts, and those chargers handle it. Devices built for 110 to 120 volts, such as some hair dryers, need a converter.
Can I bring a power bank on a flight in Vietnam?
Yes, in the cabin bag only: at most two per passenger, up to 100 Wh each, or 100 to 160 Wh with the airline's approval. Since 1 July 2026 they cannot be used to charge devices during the flight.
