Travel Adapters
2025-04-25Interactive guide for what sockets are used in which country: International Electrotechnical Commission
Universal Type Accepts plugs from most countries, used in newer hotels and most airplanes.
Universal adapters typically have a loose fit so vibrations on airplanes will cause your power plugs to fall off.
In situations like that (e.g. Boeing 777 and 787 seat power), a Schuko adapter provides a snug fit.
Cruise ships and newer hotels:
Many are equipped with USB-A and USB-C ports.
Bringing a Schuko adapter to cruise can increase the number of available US receptacles in most cruise ship's state room.
Type G Used in UK, Ireland, Hong Kong, Singapore, Malaysia, Saudi Arabia, Dubai, Qatar, Pakistan, Myanmar, Sri Lanka, Belize, Kenya, etc.
Type I Used in Australia, New Zealand, Papua New Guinea, Argentina and China.
New Zealand sockets need a 3 prong adapter: the ground pin is needed to push the safety shutter open.
Warning: a 2-pin type-I adapter will not work in some receptacles because a third (ground) pin is needed to push open an internal shutter to let the 2 "hot" pins to be inserted. Don't use force because either the wall socket or your adapter will break. Use a proper 3-pin adapter in these situations, especially in New Zealand.
China
The left receptacle accepts type A (US), type I (AU), type C (Europlug) and CEE 7/7 Schuko plug (green plug in picture below).
The right receptacle accepts type A (US), type I (AU).
Warning: a 2-pin type-I adapter will not work in some receptacles because a third (ground) pin is needed to push open an internal shutter to let the 2 "hot" pins to be inserted. Don't use force because either the wall socket or your adapter will break. Use a proper 3-pin adapter in these situations.
