This is a copy from the Radio Shack site. The quick answer is go to pretty much any electronic store or most travel stores and buy a Foreign Power Converter.
AC to AC Power Conversion (Foreign Voltage Converters)
Purpose of Converter / Explanation of Operation
voltage converters, or travel converters, are designed to convert the
voltage used in a foreign country to the voltage required for a
particular AC device. These converters are either transformer-based or solid-state
and this affects what type of devices the converter can power. In
addition to converting the power, you will often need to also use a plug adapter
Plug adapters are generally either built into the converter, or
provided as separate parts. They are also sold separately, for use with
multi-voltage devices that are designed to convert the power internally.
Selecting a Converter
are one of the more confusing of the power conversion devices. Because
of the range of voltages, plug types and converter designs, many
customers find that they need help determining exactly which converter
they need. To aid in that process, we have put together a short worksheet
to help you determine what type of converter is needed: We recommend
that you print out thi sheet when taking a number of different devices
to a different country.
First, you should determine the
electrical requirements (voltage, frequency, and wattage) for the
device(s) you will be taking with you. This information is generally on
a label or embossed into the back or bottom of the device. Make a note
of the voltage(s), frequency or frequencies, and the wattage indicated
for each device.
- The voltage may be given as either V,
VAC or VDC. The standard voltage for US devices is 120 V. Devices that
are designed to operate using different input voltages will be labeled,
such as 110/120 V, or 120/240 V.
- The frequency will be
given in Hz. The standard frequency for US devices is 60 Hz. Devices
that are designed to operate using different frequencies will be
labeled, such as 50/60 Hz.
- The wattage will be given in
either watts (W) or volt-amps (VA). If the wattage is not listed on the
device, you will need to contact the device's manufacturer for this
information. If you have the maximum current consumption (in amps), you
can calculate the wattage by multiplying the voltage (V) times the
current consumption (A).
Next, you will need to know the electrical requirements for the country you are going to be visiting.
you will need to compare your equipment requirements to the country's
information to determine whether you need a Step-up or Step-down
- If your equipment accepts the voltage and frequency provided by the country you will be visiting, then only a Plug Adapter will be required.
- If the voltage of the target country is higher than the voltage required by your device(s), you will need a Step-Up Voltage Converter.
- If the voltage of the target country is lower than the voltage required by your device(s), you will need a Step-Down Voltage Converter.
Once you know what type of converter or adapter you need, consult our list of travel power conversion products
to find one that meets your requirements.
AC outlet in many foreign bathrooms is for low-wattage devices only. To
avoid damage to your converter and/or attached device, check with your
host or hotel before powering a high-wattage device (such as a hair
dryer) from this plug.
- Do not use a voltage
converter with electronic devices such as televisions, VCR's and
computers unless the device indicates that it can handle both 50 Hz and
- Do not use heating appliances, such as hair dryers, irons and coffee-makers, on a transformer-based voltage converter.
- Do not use non-heating electronic devices, such as calculators, electric razors and portable audio players, on solid-state voltage converter.
- Do not
use 110-120 VAC Surge protectors or Uninterruptible Power supplies on a
220-240 VAC system. Even with a step-down power converter, damage could
occur as the two power systems are wired differently.
