How can I figure how many watts voltage transformer do I need?
First of all, find out how many watts do appliance take. You can find this information usually on the label located on the back or bottom of the appliance or in the specification page of instruction book of an appliance. If only amperage (AMP) is shown multiply the input voltage (i.e. 110 or 220v) by AMPS to find the watts. VOLTS x AMPS = WATTS for example, 110 V x 0.5 AMPS = 55 W Please make sure not to operate any appliance with higher wattage than the wattage rating of voltage transformer. Heavy duty transformers can be used continuously at 75% to 80% of their wattage capacity.

I have brought some electrical appliances from overseas will they work in USA?
Yes, you can buy one of our step up-down transformers according to the wattage rating of your appliance(s). Please consider to buy higher wattage transformer than the wattage rating specified on your appliance. All our heavy duty transformers (step up-down) are grounded and built-in fuse protection system and operate safely. Please remember transformers do not convert cycles (60 hz. vs. 50 hz.) and some cycle sensitive appliances like microwave ovens, stereo turn tables and analog clocks may not operate properly. However, most modern electronic devices like computers, printers and stereo systems are not affected by difference in cycles. Our heavy duty voltage transformers can also be used for North American appliances (120 volt AC) to operate in Europe (220/240 volt AC). We also recommend our voltage converters built-in voltage stabilizer models for your electronic devices to operate smoothly against power fluctuation conditions.

Can I use your step up/down transformers to connect an American 220 volt appliance like dryer?
No you cannot use our voltage transformers to connect an American 220 Volt dryer or other 220v appliances. Our transformers are desingned to convert single phase 110 60hz or 220 volt 50hz. American 220 volt consists of 2 phase of 110 volt 60hz whereas European 220 volt consists of 1 phase of 220 volt 50hz.

Can I plug more than one appliance in your transformer?
Yes, you can do that but make sure not to exceed wattage capacity of the transformer. Total wattage from all connected appliances must be less than the wattage capacity of the transformer. Some of our step up step down models have 3 or 4 output sockets to connect multiple items. You may also use a simple power strip (without surge protection feature) for multi outlet purpose.

Do voltage converters convert the cycle (50/60hz)?
All voltage converters only convert the voltage and not the cycle, however most appliances and electronics will operate normally with them. North American 110-120 volt electricity is generated at 60 Hz. (Cycles). Most foreign 220-240 volt electricity is generated at 50hz. (Cycles). This difference in cycles may cause the motor in your 60hz. North American appliance to operate slightly slower when used on 50 hz. foreign electricity. This cycle difference will also cause analog clocks and timing circuits that use Alternating Current as a timing base to keep incorrect time. Most modern electronic equipment including battery chargers, computers, printers, stereos, tape and CD players, VCR/DVD players, etc. will not be affected by the difference in cycles.

What is the difference between plug adapter and voltage transformer/converter?
The plug adapters allow you to plug your appliances into another type of electrical wall outlet. These plug adapters do not change voltage i.e. 110 volt to 220 volt or 220 volt to 110 volt. They are simply designed as solutions to the electric wall outlet configuration problem. If your device (for example laptop) is dual voltage (100V-240V) you just need a plug adapter. If your device is single voltage, you will need voltage converter and or adapter plug.

What is the difference between your voltage converter and voltage converter built-in stabilzer models??
Voltage converters convert the voltage i.e. from 110V to 220V or vice versa. The voltage converters built-in stabilizers models convert the voltage with stabilzed output. This safety feature is ideal for using electronic items in situation where the power fluctuation occurs frequently.

How to buy the right voltage converter/transformer for your appliance?
It is recommended that you buy a transformer that is rated at least 50% higher watt than that of the appliance rated wattage. For example: A 500 Watt appliance should be used with a transformer of at least 750 Watts. Purchase a transformer that is at least 50% higher than the required wattage. You will need either a voltage converter or transformer, depending on the type of equipment and or a plug adapter that is compatible with electrical outlets in the destination country.
