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.
Where you originally purchased your appliances and chargers.
Select the region you are flying to next.
Check this if packing a high-wattage heating appliance (such as a Dyson Airwrap, Revlon brush, or standard 110V hair dryer).
Modern USB-C laptop and phone blocks rated "Input: 100–240V ~ 50/60Hz".
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.

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.
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) |
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.
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.
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.
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.
