The TK1650 is a kit consisting of a PB1650 voltage converter, 5 additional adapters for plugging the voltage converter into other types of outlets, and a convenient carrying case for everything. By attaching the appropriate adapter to the PB1650's built-in plug (whichever adapter matches the outlet present) it can be used in over 150 countries.
If you need to operate a North American 110-120 volt hair dryer, curling iron, heating pad, lamp/light, or other non-electronic appliance in a country where the voltage supplied by the electrical outlets is 220-240 volts, the TK1650 voltage converter is probably a better solution than a step down transformer. Voltage converters do the same thing transformers do. Namely, they take the 220-240 volt electricity supplied in most countries, and convert the voltage down to 110-120 volts for use by the appliance. While voltage converters and transformers do the same thing, they do it in different ways, and the difference is very important.
The advantage of a voltage converter is that for high-wattage appliances like hair dryers (which are often 1200-1500 watts) and other simple heating appliances, a voltage converter is a lot smaller, lighter, less expensive and more convenient than a transformer with a similar wattage capacity. A 1500 watt transformer could weigh close to 30 pounds! The TK1650 weighs about 2 pounds.
The downside is that while a voltage converter works fine for a simple non-electronic appliance like a hair dryer, voltage converters should not be used with electronics like laptops, televisions, stereos, etc. Never plug a laptop into a voltage converter.
But if you need to plug in a beverage heater, clothes steamer, coffee maker, electric blanket, food/bottle warmer, hair dryer, hair roller set, heating pad, hot plate, incandescent lamp, iron or something like that, a voltage converter should do the job. As long as the appliance doesn't contain any electronics like a clock or timer, a digital temperature control, an auto-off feature or anything like that.
Be sure that your appliance's plug only has the two vertical blades, and does not have the third, round grounding pin. The socket on the TK1650 voltage converter does not accept a 3-pin grounded plug.
The TK1650 is a "combo unit" in that it has two modes. In "low power mode" it functions as a voltage transformer, and is safe for use with electronics. But in low power mode, the TK1650 can only handle electronics up to 50 watts. So anything electronic would have to be very low power. Battery chargers and electric shavers are often below 50 watts, and therefore can usually be safely used with the TK1650. But you have to be absolutely, positively sure that it's less than 50 watts. Otherwise, the TK1650 will switch over to "high power mode" where it can handle up to 1600 watts, but only for non-electronic heating appliances.
Compatibility
The TK1650 voltage converter is built with a CEE 7/16 "Europlug" type of plug, and ships with five adapters to connect to its built-in plug so that it can plug into other types of outlets. By attaching the appropriate adapter matching the type of outlet present, the TK1650 can be used in over 150 countries!
