VCT- International Travel Voltage Converter/Foreign Plug Adapter Kit - Dual 50 Watt / 1600 Watts (Model VM 6)

Prompt and professional. Recommend. A+A+A+

To actually convert a 220V sinusoidal waveform into a 110V sinusoidal waveform, you need to use an AC transformer. This method is safe for all low-power appliances. For higher power, however, the AC transformer required is bulky and heavy (around 20 pounds for 1000W), making it impractical as a travel voltage converter.This item offered here ( INTERNATIONAL VOLTAGE CONVERTER ADAPTOR KIT)  does not contain an AC transformer. Instead, it uses a solid-state switch inside that chops off part of the 220V sinusoidal waveform. The resulted waveform, as seen by the appliance, is highly distorted and is far from an 110V sinusoidal voltage.The product description says: "Converts 220/240V foreign electricity to 110/120V high wattage travel heating appliance". Note that it says HEATING appliance. That means it has to be a resistive load which works regardless of distorted waveform. If you try to use any electronic appliance (such as TV, computer or battery charger) on this "converter", it will probably be fried in an instant!My advise is to stay away from this potentially destructive product. If you must bring electronic appliances with your oversea trips, make sure they are rated for universal voltage of 100-240V AC. That way, you can safely use them in other countries without the need for a volatge converter. Power supplies for most portable electronics (laptop, camcorder, cell-phone, electric shavers, etc.) are already designed for universal voltage, although some of them may require you to physically flip a switch.But don't forget, even if you don't need a voltage converter, you still must bring a set of plug adapters for foreign countries.
