![]() For these types of situations you need to buy a transformer that is at least double the products rating. Some items, such as, laser printers and power tools spike when you turn them on. Using converter/transformer to their maximum capacity will eventually burn out the converter/transformer after prolonged use. We recommend using a converter/transformer that is rated at least a 25% higher than your products wattage rating. Select the converter/transformer according to the wattage rating of your appliance. Look for the watt rating on the appliance or calculate the wattage by multiplying voltage x amps. Now that you know that you require a voltage converter/transformer, you need to determine which one or what kind.Now, if the voltage rating states 110V or 120V it means that your product is only single volt and it will require a step down converter/transformer for use in 220V countries abroad. However, you may need a plug adapter to plug it in to the outlets abroad. Most laptops and camcorder battery chargers are dual voltage. Look for the voltage rating on your appliance, if the rating states something similar to 100V~240V that means your product is dual voltage, in this case you can use your product in a 220V without a transformer/converter. Determine if your appliance actually requires a transformer/converter for use in abroad. ![]() Selecting the correct converter or transformer Most voltage transformers are both step up and down, you can switch them to operate as step down or step up. On the other hand, Step up voltage converter/transformer will convert voltage from 110V to 220V thus, allowing you to use 220V products in the US (110V). Step down voltage converter/transformer will convert voltage from 220V to 110V thus, allowing you to use your US (110V) products abroad in 220V countries. They can only be used to convert the voltage. Voltage converters and transformers do not convert cycles. Refer to the World plug adapter guide to find the correct plug adapters. In this case, carry all types of plug adapters for the traveling country. Many countries have multiple type of outlets. In fact, most countries have a different plug adapter from the US plug. Not all countries have the standard US flat prong electrical outlet. The third difference is the plug adapters. Also, transformers are not recommended for use with heat producing appliances such as heaters, steamers and coffee heaters. When in doubt, consult with the manufacturer of the product. Other products such espresso makers and turntables may not operate properly with a voltage converter if they only operate on single frequency. ![]() You'll need to double check the frequency for analog products such as clocks as this can cause it to keep incorrect time. The difference in frequency may cause a motorized 60 Hz device to operate slower on 50 Hz. Most electrical products are not affected by the cycle change because they internally convert AC voltage to DC voltage and many devices support both cycles. Countries use either 60 Hz (USA) or 50 Hz (UK). Many countries operate on both 110V and 220V.Īs mentioned above, not only the voltage differ within countries but so does frequency (cycles per second). In general, 110V includes voltage range of 100-125V and 220V includes 220-250V.
