When Traveling TO Countries with Type O
If you're traveling from a country that doesn't use Type O power plugs, you'll need a power plug adapter to physically fit your devices into Type O outlets. Make sure to check voltage compatibility as well - most countries using Type O operate at 230V.
When Traveling FROM Countries with Type O
If you're traveling from a country with Type O to countries with different power plug types, consider a universal travel adapter that includes multiple power plug configurations. This will work in 150+ countries worldwide.
Common Misconceptions
Any plug that physically fits a Type O socket is safe to use
Mechanical fit does not guarantee proper grounding or voltage compatibility. Always check your device rating and use a properly grounded adapter when needed.
Thailand uses the same system as the rest of Southeast Asia
Thailand has its own Type O standard and a mix of legacy sockets. Neighboring countries may use different combinations of Type A, B, C, F, or G.
Questions fréquentes
What countries use Type O power plugs?
Type O power plugs are used in 1 countries, primarily in Asia.
Is Type O grounded?
Yes, Type O power plugs are grounded (earthed), providing additional safety for high-power appliances.
Can I use a Type O adapter for all my devices?
A plug adapter only changes the physical shape - it doesn't convert voltage. Check that your devices support the voltage used in your destination country (230V). Most modern electronics are dual voltage (100-240V), but always verify on the device label.
Where can I buy a Type O adapter?
Type O adapters are available at airports, electronics stores, online retailers, and travel shops. For better prices and selection, purchase before your trip. Universal travel adapters that include Type O are also a good option for frequent travelers.
