Reference: Interactive guide for what sockets are used in which
country:
International
Electrotechnical Commission
Universal Type Accepts plugs from most
countries, used in modern hotels and long haul airplanes.
They tend to have a looser fit so vibrations on airplanes can
cause the power plugs to come loose.
Cruise ships and high end hotels are equipped with receptacles
from different continents.
Many are equipped with USB-A ports, and USB-C ports (on newer
ships).
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.
