The Only Travel Adapter You’ll Need on Jeju Island
There’s nothing worse than arriving in Jeju Island and realizing your charger is completely useless. We don’t sell travel adapters, but we did the homework so you don’t have to. After researching voltage, outlet types, and safety, this one is your best bet:
If you’re already en route or at your destination and don’t have a power adapter, there’s usually no need to panic. You’ll likely find one nearby. But bringing your own next time saves you the hassle.
Jeju Island travelers often continue to Japan, China, or the Philippines. It’s smart to check outlet types in advance.
Do You Need a Voltage Converter?
Planning a trip to Jeju Island? The voltage there doesn’t match the 120V we use in the U.S., so you’ll probably need a voltage converter.
To be safe, always inspect the voltage specifications on your electronics before plugging them in overseas. If you see “100-240V, 50/60 Hz”, your device is dual voltage and won’t need a converter. Most tablets, laptops, cameras, and rechargeable personal care items support this.

More About Jeju Island
Jeju is like Hawaii, Korean-style—volcanic landscapes, waterfalls, lava tubes, and beach cliffs, yet still uniquely Korean. Mount Hallasan is a sleeper-peak—fantastic for hiking, and not ridiculously crowded with tourists.
There’s also the UNESCO-listed lava tube caves and Bijarim Forest, home to a 900-year-old nutmeg tree. Plus, you’ll spot legendary “Haenyeo” women divers gathering seafood the old-school way—no tanks, just grit and skill.
Jeju gets mild winters and warm summers—great for exploring year-round. And while it’s super popular with domestic tourists, with a little curiosity you’ll find hidden waterfalls, quiet farms, and artsy villages away from the crowds.
Jeju Island uses the same plugs and outlets as the rest of South Korea.
