China
Voltage in Mainland China is 220V, 50 Hz. A variety of
electrical outlets can be found in China.
A common type of outlet is shown at right. This outlet
can accept the standard Type A and common
Type I plugs as well as Type
C plugs. Both the upper and lower outlets can be used
simultaneously.
The official plug type is like type A but slightly shorter
and without holes in blades. Type A and I outlets are

NOTES ON TYPE A PLUGS/OUTLETS
In the U.S. & Canada, two-blade plugs are often polarized,
with one blade larger than the other. Most outlets are designed
to handle these. The larger blade is the neutral side of the
current. This is a safety feature intended so the plug can
be inserted one way only to reduce the chance of accidental
shock. If you try to plug a modern plug into an old-style
receptacle for equal size blades, it won't go in unless you
file down the larger blade to the older plug size. Outside
the US, many countries with Type A use the old style plug,
and a newer US plug with unequal pins might pose a problem.
This can be bypassed using an adaptor (found in many travel
kits) which converts the newer Type A plug to the older model
with equal-sized blades. Be aware, though, that you might
also be bypassing the protection that polarization provides.
Type C
Type I - Oblique flat blades with ground (inverted
V)
Type G - Rectangular blade plug
Type M - "South African" Plug
