巴西电流的电压是110伏特、60赫兹。如果您到巴西旅游带不能用110伏特、在60赫兹的电器，需要个电压converter。 F& ^% e! x2 z/ C7 q$ a
1 b4 R9 M/ R! C+ F6 nThere are three main types of voltage converter. Resistor-network converters will usually be advertised as supporting something like 50-1600 Watts. They are light-weight and support high-wattage electrical appliances like hair dryers and irons. However, they can only be used for short periods of time and are not ideal for digital devices.

Transformers will have a much lower maximum Watt rating, usually 50 or 100. Transformers can often be used continuously and provide better electricity for low wattage appliances like battery chargers, radios, laptop computers, cameras, mp3 players and camcorders. However, they are heavy because they contain large iron rods and lots of copper wire.

Some companies sell combination converters that include both a resistor network and a transformer in the same package. This kind of converter will usually come with a switch that switches between the two modes. If you absolutely need both types of converter, then this is the type to buy.! n: N$ \4 x4 ~' Q7 n, k3 C( |
