International Plug Type, Voltage & Dual-Voltage Appliance Checker
Verify international plug types and electrical voltage across Europe, the UK, Singapore, Thailand, Bali, Vietnam, and Japan so you know which adapter to pack and avoid burning out 110-volt hair dryers or straighteners.

Safe with Passive Type C / Type F Pin Adapter
Your laptop, smartphone, camera, and USB-C GaN chargers are automatically dual-voltage (100–240V, 50/60Hz). You do NOT need a heavy voltage transformer—only a simple passive plug adapter for Type C / Type F (2 Round Pins, 4.0–4.8mm). Bali, Georgia, Azerbaijan, and all of Continental Europe use recessed two-round-pin Schuko (Type F) or Europlug (Type C) outlets. Vietnam and Cambodia mostly use hybrid outlets that accept both two-round-pin (Type C) and flat-pin (Type A) plugs, though a Type C adapter guarantees a snug fit.
Recommended Action Plan & Compliance Steps
- 1Adapter to Pack: Bring a compact Type C / Type F (2 Round Pins, 4.0–4.8mm) adapter (or a universal GaN travel adapter with built-in USB-C PD ports).
- 2Regional Socket Tip: Bali, Georgia, Azerbaijan, and all of Continental Europe use recessed two-round-pin Schuko (Type F) or Europlug (Type C) outlets. Vietnam and Cambodia mostly use hybrid outlets that accept both two-round-pin (Type C) and flat-pin (Type A) plugs, though a Type C adapter guarantees a snug fit.
- 3How to read any charger’s fine print: Look for "INPUT: 100–240V ~ 50/60Hz" etched on your power brick. If it says 100–240V, it works safely in every country on Earth with just a $3 pin adapter.
- 4Avoid plugging heavy universal multi-blocks straight into worn-out hotel wall sockets where gravity pulls them loose—carry a short 1-meter figure-8 (C7) cord or dedicated country plug head for rock-solid contact.

Plug Adapters vs. Voltage Converters: What Every International Traveler Must Know
A passive travel adapter only changes the physical shape of the metal prongs—it does NOT change the electrical voltage coming out of the wall. Understanding the difference between 100–240V electronics and 110V heating appliances prevents fried gear and tripped hotel breakers.
Why Thailand & the Philippines Fry So Many US/Japanese Appliances
- • In Europe or the UK, a North American flat-pin plug physically cannot enter the wall socket without an adapter, reminding travelers they are in a 230V country.
- • In Thailand, the Philippines, and parts of Vietnam and Cambodia, wall sockets are engineered as hybrid slots that accept both US flat blades (Type A/B) and European round pins (Type C) directly.
- • Because a 110V American hair dryer, curling iron, or garment steamer plugs straight into a Bangkok or Manila wall outlet without an adapter, travelers plug them in directly—sending 220 volts through a 110-volt heating coil and burning it out within seconds.
Why All Modern Laptops, Phones & Cameras Are Automatically Dual-Voltage
- • Every Apple MacBook, iPhone, Samsung Galaxy, iPad, Nintendo Switch, camera battery charger, and GaN USB-C charger manufactured in the last 15 years uses a switched-mode power supply rated for 100–240V at 50/60Hz.
- • You never need a heavy voltage converter or transformer for digital electronics—only a simple passive plug adapter so the prongs fit the wall.
- • Note that nearly all universal travel adapters have an internal 8A or 10A fuse (max ~1,100W at 110V or ~2,300W at 230V) and explicitly warn "DO NOT USE WITH HAIR DRYERS" on the casing.
World Plug Types & Voltage Quick Reference by Destination
Socket standard, mains voltage, and compatibility tips for popular international routes.
| Destination Countries | Plug Types | Grid Voltage & Frequency | Practical Compatibility Note |
|---|---|---|---|
| UK, Singapore, Malaysia, Hong Kong, Ireland, UAE, Malta | Type G | 230V / 50Hz | 3 rectangular prongs; remember to flip the individual wall socket switch ON |
| EU (Schengen), Bali (Indonesia), Georgia, Azerbaijan, Turkey, South Korea | Type C & Type F | 220–230V / 50Hz | 2 round pins; Type C Europlug fits both recessed Type F and standard Type C sockets |
| Thailand, Vietnam, Cambodia, Philippines | Type A, B & C (Hybrid) | 220V / 50–60Hz | Hybrid outlets accept flat US pins and round EU pins, but voltage is 220V (fatal to 110V hair tools) |
| Japan | Type A (Some Type B) | 100V / 50–60Hz | 2 flat parallel pins; pack a 3-prong to 2-prong ground adapter for 3-pin US laptop cords |
| USA, Canada, Mexico, Colombia, Taiwan | Type A & Type B | 110–120V / 60Hz | 2 flat parallel pins + ground pin; 230V European hair tools will run weak here |
| Australia, New Zealand, Argentina, China | Type I | 220–240V / 50Hz | 2 flat angled V-shaped blades (+ ground pin) |
Frequently Asked Questions — World Plug & Voltage Checker
Does a Dyson Airwrap or Supersonic purchased in the US or Japan work in Europe, Bali, or Thailand?
No. Dyson hair tools contain a precision microprocessor that strictly locks the device to the voltage region where it was purchased (either 100–120V for North America/Japan/Taiwan OR 220–240V for Europe/UK/Asia/Australia). Even if you buy a heavy step-down voltage transformer, a 120V Dyson Airwrap will flash a red fault light and refuse to run cleanly on 220–240V grids.
Why does my universal travel adapter keep falling out of hotel wall sockets?
Bulky all-in-one universal cube adapters stick out 7–9 cm from the wall, creating leverage that pulls their skinny pins out of worn-out hotel receptacles—especially in Thailand, Vietnam, and older European buildings. A small $2 country-specific plug adapter (especially a thick-pinned Schuko Type F or UK Type G plug) sits flush against the wall and never falls out.
How can I tell if my flat iron or curling iron is dual-voltage?
Inspect the fine print stamped onto the handle or cord tag near the plug. If it reads "100–240V" or "110V–240V", it is dual-voltage (some models adjust automatically, while others have a small recessed dial you turn with a coin from 120V to 240V). If it only lists "120V ~ 60Hz" or "110V", it is single-voltage and must not be used on 220–240V outlets.
Do planes and airport lounges have universal power outlets?
Yes. Most long-haul aircraft seats and international airport lounges feature universal multi-standard sockets that accept US Type A/B, European Type C, and UK Type G plugs at 110V/60Hz (typically capped at 75W–100W per seat), alongside high-output USB-A and USB-C ports.
