Power Plug Types Around the World
There are 15 different plug types used around the world, and plugging into the wrong voltage can fry your electronics. This guide covers everything you need to know so you pack the right adapter — and protect your gear.
The Major Plug Types Explained
Type A (two flat parallel pins) — Used in the USA, Canada, Mexico, Japan, and much of Central America. Voltage: 110–120V.
Type B (two flat pins + round grounding pin) — Common alongside Type A in North America. Voltage: 110–120V.
Type C (two round pins) — The most universal plug type, used across Europe, South America, Asia, and Africa. Voltage: 220–240V.
Type G (three rectangular pins in triangle) — UK, Ireland, Singapore, Malaysia, Hong Kong. Voltage: 230V. Has built-in fuse for safety.
Type I (two or three flat angled pins) — Australia, New Zealand, China, Argentina. Voltage: 230V.
Voltage: The Thing That Actually Matters
Most of the world runs on 220–240V. North America and parts of Asia run on 110–120V. Plugging a 110V device into a 220V outlet without a converter can permanently damage it.
Check your device's label (usually on the adapter brick). If it says '100–240V', you're safe anywhere in the world — you just need a physical adapter, not a voltage converter.
Most modern electronics (laptops, phone chargers, camera chargers) are dual-voltage (100–240V). Hair dryers, flat irons, and shavers often are not — check before you travel.
Adapter vs Converter — What's the Difference?
An adapter only changes the physical shape of the plug — it does not change the voltage. Use one when your device already accepts the destination voltage.
A converter (or transformer) changes the voltage. Use one only for devices that are single-voltage and won't work otherwise. They're heavy and expensive.
Best advice: buy dual-voltage versions of your personal care appliances (hair dryer, curler) rather than hauling a heavy converter.
Best Universal Travel Adapters
A universal travel adapter covers Types A, B, C, G, and I — enough for 99% of destinations. Look for one with built-in USB-A and USB-C ports.
Top-rated options include the BESTEK Universal, EPICKA Universal, and OREI World Travel Adapter. Expect to pay $15–35 for a reliable one.
Avoid very cheap adapters — they often skip safety features like surge protection and can overheat.
