Type I Plug Explained: Countries, Voltage & Travel Adapter Guide (2026)
If you're traveling to Australia, New Zealand, China, or several Pacific countries, you'll likely encounter the Type I plug. Understanding its design, voltage, and compatibility can help you avoid charging problems during your trip.
In this guide, we'll explain where the Type I plug is used, what voltage it supports, and whether you'll need a travel adapter.
What Is a Type I Plug?
The Type I plug features two flat pins arranged in a V-shape. Many versions also include a vertical grounding pin underneath.
It is one of the most recognizable plug types and is commonly found throughout Oceania and parts of Asia.
- Two angled flat pins
- Optional grounding pin
- Voltage: 220–240V

Countries That Use the Type I Plug

| New Zealand | Type I | 230V |

Do You Need a Travel Adapter?
If your charger uses a different plug shape, you'll need a travel adapter.
Most modern phone, laptop, and camera chargers support 100–240V, meaning they only require a plug adapter rather than a voltage converter.
Always check the label on your charger before traveling.
Do You Need a Voltage Converter?
Probably not.
Most USB-C chargers, MacBook chargers, and modern electronics automatically support worldwide voltage.
Only older appliances like hair dryers or curling irons may require a voltage converter.
Why a Universal Travel Adapter Is Better
Instead of carrying different adapters for every destination, many travelers choose a universal travel adapter.
An Olloes GaN Travel Adapter supports plug standards used in over 200 countries while offering fast USB-C charging for laptops, phones, tablets, cameras, and other devices.
