Tihany, Hungary - 220V at 50Hz


TYPE C : This two-wire plug is ungrounded and has two round prongs. It is popularly known as the Europlug (described in CEE 7/16). It will mate with any socket that accepts 4.0-4.8 mm round contacts on 19 mm centres. This plug is generally limited for use in class II applications that require 2.5 amps or less. It is unpolarised.

TYPE F : Known as CEE 7/4 (a.k.a. "Schuko plug"), Type F is similar to C, except that it is round and has the addition of two grounding clips on the side of the plug. It has two 4.8 mm round contacts on 19 mm centres. Because the CEE 7/4 plug can be inserted in either direction into the receptacle, the Schuko connection system is unpolarised (i.e. line and neutral are connected at random). It is used in applications up to 16 amps.



Plug Adapters

Adapters do not convert electricity, they simply allow a dual-voltage appliance, a transformer or a converter from one country to be plugged into the wall outlet of another country. The plug of a Continental European appliance will not fit into an outlet in a foreign country without an adapter.


Converters and transformers both step-up or step-down voltage, but there is a difference in their uses. Converters should be used only with "electric" products, such as those with simple heating devices or have mechanical motors. Examples are hair dryers, steam irons, shavers, toothbrushes or small fans. Converters are not designed for "continuous duty," and therefore should only be used for short periods of time (1 to 2 hours). Most converters can only be used with ungrounded appliances (2 pins on the plug). Converters must be unplugged from the wall when not in use.


Transformers also step-up or step-down voltage, but they are to be used with "electronic" products and tend to be more expensive than converters. Electronic products are those that have an integrated chip or circuit, including radios, CD or DVD players, shavers, camcorder battery rechargers, computers, computer printers, fax machines, and televisions. Transformers can also be used with electric appliances and may be thusly operated continually for many days. The advantage of converters, however, is that they are lighter and less expensive.

Computers are, obviously, electronic devices and therefore should be used with a transformer, unless they are dual voltage. Fortunately, most laptop battery chargers and AC adapters are dual voltage (check yours!), so they can be used with only a plug adapter.
