How to use power adapter


Step 1

Check the electrical system and plug type for the country where you will be traveling. Consult a reference that lists electrical specifications for countries, such as Kropla World Electric Guide (see Resource below) or a table included in a travel adapter kit. For example, the electrical system in Argentina provides 220 volts.

 

Step 2

Purchase a travel adapter to fit the electrical outlet for the country based on the type of plug or socket used. Plug adapters bear a letter corresponding to the plug configuration. Single adapters are available for select countries, such as a C adapter for power outlets in Argentina, Albania, Brazil, Italy and Sweden or a G adapter for the United Kingdom.

 

Step 3

Identify the power requirements for the device by checking the label on the back of the device or information on the power transformer for the voltage and amperage to determine whether a converter is needed. Alternatively, consult the owner's manual for electrical or power requirements. Appliances such as a hair dryer or devices such as a cell phone may specify a dual-voltage rating for 110 volts and 220 volts, so that they don't require a power converter in many countries -- only a plug adapter for the outlet. If the device doesn't specify a dual-voltage rating, it is a single-voltage appliance.

 

Step 4

Calculate the wattage for the device if it's not specified by multiplying the voltage (V) and the amperage (A or amps). For example, 110 V x 2 A = 220 watts. Wattage is the amount of electricity needed by a device for power or for charging. If a small device requires a small wattage and doesn't have a transformer, it may be damaged or "fried" by a country's electrical system because a transformer or converter isn't used to prevent a power surge.

 

Step 5

Purchase a converter, converter/transformer or converter/transformer with adapter as needed based on determinations from Steps 2 to 4. Mobility International USA (MIUSA) recommends using a converter that is rated at least 50 percent higher than needed. For example, use a 350-watt converter or higher for a 220-watt device.

 

Step 6

Attach the power cord to the device when you arrive at your destination. If you also use a power converter/transformer, then plug the device's power cord into the power socket on the converter.

 

Step 7

Match the prongs of the power plug for the device or converter to the slots on the adapter and then insert the plug adapter into the wall outlet. Prevent a power surge or sparks by checking that the cord and adapter fit tightly together before plugging it into a working power supply.
