FAQ Section:

When decided on which Transformer will be suitable for your appliance/s, it is important to consider the Power Rating of the device/s you wish to run on the Transformer.

To determine the Power Rating of your appliance/s, you must determine the total wattage (W) or total ampere (A). This will be presented on the product in a electrical specification label, or in the product manual.

Once the total wattage (W) or total ampere (A) is determined, please use our ‘Calculator’ located on the tab section of this page. This calculator will help guide you on which Transformer is recommended using your appliance/s details.

Always note that the Transformer must always be 20-25% higher in wattage (W) rating than the total wattage of your appliance/s.

E.g: Playstation 3 uses 380 Watts, so you will need the 500 watt rated Step Down transformer.

If a motor is included in your appliance/s, then you should select a Step Down Transformer rating approx 25% higher than your motor as a buffer.  

Motors have a higher power demand on the Step Down Transformer and draw higher start-up currents which need to be allowed for.

Most motors have a rating plate on them with their power (VA), wattage (W) and/or ampere (A) rating.

If so, how critical is this timing device? Our Transformers convert the voltage (V) and cannot change the frequency (Hz). 

Please note Australia’s power grid supply operates at 50Hz. 

If a timing device is included, the speed of the device may change due to the frequency difference in the power grid. This results in the appliance/s operating at 50Hz (Australia) when designed for 60HZ (Western Japan). An example of which appliance/s may be more affected by this are: old clocks, motors/fans/microwaves.

 Most modern electronic devices should not be affected. Please read further about frequency for more information.

Calculation for Wattage:

Wattage (W) = Ampere (A) x Voltage (V)

An Example is Wattage = 5 Amps x 110 Volts = 550 Watts

Please check the total watts (W or VA) of all devices and ensure this is 20% lower than the power rating (W or VA) of the Step Down Transformer. If using more than two devices, please use a USA Powerboard to run multiples devices.

  1. Paul Wheeler (verified owner)

    It arrived promptly , well packaged. It works perfectly powering a small Japanese iron for craft purposes , the transformer runs cool and hasn’t missed a beat, just like the American step down I used for running American voltage synthesisers.The staff member I spoke to helped my decision on which wattage to purchase . I have and always will recommend Tortech to my friends because they are a courteous and helpful,company selling very reliable equipment.

  2. Lyn (verified owner)

    I found the description and explanation of this transformer very helpful, as I now less than nothing about these things. The transformer works perfectly with the small rice cooker I bought in Japan and – importantly to me – is not as ugly as the big black ones. Very happy with my purchase.

  3. Chris (verified owner)

    Was shipped very quickly, and the transformer works perfectly (and is really affordable!). Forget about buying from ebay, save yourself the hassle and get one from Tortech

  4. Alan

    This transformer was received promptly and well packed. It works well and most of all quietly for converting from 100v to 240-250V with my audiophile HIFI equipment I purchased from Japan. Hard to get such a transformer that has both 100v conversion (Japanese) and also be quiet as most have an annoying hum and can be very expensive from say UK or Asia and competing models in Australia cant compete with this quality for this item. This one is barely audible which helps with enjoyment of music listening. Good service when I rang to enquire about it and ordered online with no hassles. Would recommend this company for related services.

  5. Long Hoang (verified owner)

    Second times bought this 2000W Japanese Stepdown transformer. It works perfectly with the Japanese made Jojirushi IH pressure rice cooker. Cheap price and quick delivery. Thank you Tortech.

  6. Jenny W (verified owner)

    It arrived very quickly, delivery was smooth (even to our address, which is sometimes difficult for the postman to find) because we were texted a notification that it was arriving on the day of delivery, and the product works very well. We are now the happy owners of a Japanese model bread maker, thanks to this transformer.

    Customer service from this company is excellent. Prompt, courteous, and helpful.

  7. Mori (verified owner)

    Functionality of the device is excellent but it could be a much better product had it been smaller and lighter.
