Power conversion plugs help you power your electronic devices. They convert 120-volt AC power to six to twelve-volt DC power. When using these plugs, you should check the labels on your appliances to make sure they accept the correct voltage. Usually, the label will be located near the receptacle of the DC plug. If you are traveling to a different country or using an adapter for your home appliances, make sure you know the voltages and adapter types.

The international Electrotechnical Commission (IEC) publishes a guide that groups plugs by letter designations. While this is helpful, it does not cover every variation. For example, North American plugs are generally polarized, whereas those used in Japan are non-polarized. However, if you purchase a plug from Japan, it will usually work.

Another option is to use a dual-voltage device. These can be used on both 240 and 120-volt outlets. In addition, there are some devices that require converters but will operate with either one. If you are unsure of which type of power you need, read the instructions on your power cord or your device's manual.

If you have an American plug, you will need an adapter or converter in order to charge your electronics in another country. Adapters change the plug's configuration to fit into the foreign wall socket. Converters, on the other hand, change the voltage and type of electricity. If you have a dual voltage appliance, you don't need a converter.

If you need to use a 120-volt appliance in a country where the power outlets are different, you will need to buy an adapter. This will save you the hassle of having to buy a replacement device in the destination country. Most modern devices can handle a wide range of voltages. The instructions for a specific device will indicate how many different voltages it can handle. Most adapters will also have a USB port that allows you to charge your devices.
