Dynastar Step Up & Step Down Voltage Converter and Transformer, 110-220 to 220-240 Volts; Heavy Duty, Extra Durable Coil, 5-Year-, 500 Watts

The versatile step up/step down voltage converter and transformer is engineered to keep you powered up wherever you are in the world. Easily determine the wattage of your appliances by following the convenient guide below. **How Do You Know Which Converter You Need?** Check the total wattage consumed by your electrical devices and multiply that figure by 3. You require a converter rated for at least three times the total wattage of the devices to allow sufficient room for potential power surges. To identify the correct wattage rating for the voltage converter/transformer you need, first find the wattage of the electronic devices or appliances you intend to use. This data can be located on the manufacturer's label found on the back or bottom of the device or appliance, or in the specifications section of the appliance's owner's manual. Note: Watts may be listed as "W" on your appliance. If you cannot find "Watts" or "W" on the label, you might find "Amps," also referred to as "amperage" or "A". If only the amperage is displayed, multiply the input voltage by the amperage to calculate the wattage. Use the following example as a reference: Volts x Amps = Watts (e.g., 110V x 1.5 A = 165W). After summing the watts of all the devices you plan to use with the transformer, add up the total watts and multiply that figure by 3
