If you’re already on your way—or even at your destination—and realized you forgot a power adapter, no big deal. In most countries, you can usually grab one at the airport or pick one up at a nearby shop.
That said, it’s a smart move to get one ahead of time for your next trip. You’ll know it works, skip the last-minute scramble, and avoid getting stuck with a cheap one that might not hold up.
Halong is often part of a wider Southeast Asia trip that includes Thailand, Laos, or Cambodia. Make sure your plugs will work at each stop.
Do You Need a Voltage Converter?
Planning a trip to Halong? The voltage there doesn’t match the 120V we use in the U.S., so you’ll probably need a voltage converter.
Always check your device’s power label before traveling. If it says “100-240V, 50/60 Hz”, your device can handle different voltages worldwide without needing a converter. This applies to most laptops, tablets, cameras, phones, and rechargeable personal care devices.
