Unlike most other voltage transformers for Japan, PowerBright transformers can be used as either a step up "booster" transformer or a step down "reducer" transformer. This means a PowerBright transformer will work whether you're bringing a North American 120 volt appliance to Japan, or bringing a 100 volt Japanese appliance to North America. Simply select the input voltage coming from the wall outlet via a jumper on the back of the unit, and plug your appliance into the outlet on the front of the unit which matches your appliance's required input voltage.

  • Can be used in 110-120 volt countries and 100 volt countries
  • Converts from 100 volts to 110-120 volts (in step up mode)
  • Converts from 110-120 volts to 100 volts (in step down mode)
  • On/Off switch
  • Fuse protected (2 spare 30 amp cartridge fuses included)
  • CE Approved

Unlike most other voltage transformers for Japan, PowerBright transformers can be used as either a step up "booster" transformer or a step down "reducer" transformer. This means a PowerBright transformer will work whether you're bringing a North American 120 volt appliance to Japan, or bringing a 100 volt Japanese appliance to North America. Simply select the input voltage coming from the wall outlet via a jumper on the back of the unit, and plug your appliance into the outlet on the front of the unit which matches your appliance's required input voltage.

If you are bringing a U.S. or Canadian 110-120 volt appliance to Japan, you need a step up "booster" transformer. Step up transformers take the 100 volt electricity supplied by Japanese wall outlets, and convert the voltage up to 110-120 volts for use by the North American appliance. PowerBright transformers do that.

On the other hand, if you are bringing a 100 volt Japanese appliance to the U.S. or Canada where the voltage is 110-120 volts, you need a step down "reducer" transformer. Step down transformers take the 110-120 volt electricity supplied by American and Canadian wall outlets, and convert the voltage down to 100 volts for use by the Japanese appliance. The same PowerBright transformer will do that too.

But do I need a voltage transformer? Or would a plug adapter be enough?
Well, that depends on what you need to plug in. If your appliance's voltage matches the local voltage at your destination, then a plug adapter will do just fine all by itself. But if your appliance is not compatible with the local voltage, that's when a voltage transformer comes in. Voltage transformers actually change the local voltage to a voltage that's suitable for your appliance.

Wall outlets in Japan usually supply electricity at 100 volts AC. If you're plugging in an appliance that was built for 100 volt electrical input, or an appliance that is compatible with multiple voltages, then an adapter is all you need.

But plug adapters do not change voltage, so the electricity coming through the adapter will still be the same 100 volts the wall outlet is supplying. North American outlets supply electricity at between 110 and 120 volts. Consequently, North American appliances are generally built for 110-120 volts. But that doesn't mean that your specific appliance isn't already compatible with the Japanese voltage -- it may very well be. In fact, most chargers for modern smartphones/iPhones, tablets/iPads, laptops and digital cameras are already multi-voltage compatible. Check your charger for something to the effect of "Input: 100-240V" ... voila!

On the other hand, most "conventional appliances" like kitchen items, audio/video equipment, vacuum cleaners, lamps and lights, and most bath appliances are not compatible with multiple voltages, and need to have the voltage changed by way of a voltage transformer like this one. The only way to know for sure is to check the label, or the back of the manual, and determine the specific electrical input requirements for the specific device/appliance in question.

Is this transformer big enough to support my appliance?
The transformer you buy must be capable of supporting the amps and/or watts that your appliance needs in order to operate. If the transformer is too small, you will blow the fuse. The model VC3000J supports 3000 watts. So as long as your appliance is 3000 watts or less, this transformer should be fine.

The watts and/or amps that your appliance requires can be found on a label on the appliance (usually on the bottom or back) where the brand name and model number appear. If the appliance uses a charger or AC adapter, the information will appear on the charger. Look for something like this: "Input: 120V 60Hz 100W " The "W" number is the watts. For this model transformer, that "W" number should be 3000 or below.

Sometimes the label will show amps instead of watts. In that case the information would look something like: "Input: 120V 60Hz 10.0A " If the label lists amps, you can figure out a rough approximation of the watts by multiplying the amps by the volts (the "V" number). Example: 120 volts x 10.0 amps = 1200 watts. In this case, the VC3000J would in fact be big enough to support the appliance. PowerBright manufactures transformers that support up to 3000 watts!
