If you are unsure about what stepdown you will need please check these frequently asked questions:

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. 

If still unsure please contact us to work out which stepdown transformer you will need.

  1. Matt

    Light, compact and works longer then other stepdowns. I have to buy a tortech stepdown as my other stopped working after 40 mins and I was told this was usual, the Tortech product works like a beaut, thanks tortech

  2. Frank

    Excellent product that works faultlessly, fast delivery, good shopping experience.

  3. George K

    Works well. Needed a reliable step-down transformer for my Kitchen aid and headpad. Really did not want something that would damage my Infrared heatpad as it is a pricey item that i specifically ordered from the USA because they are not available here. Was reassured by assistance over the phone that these stepdowns are safer as they are different as they use the round transformers inside which means they run for long periods of time.
    Pleased to say Ive been running my heapad for hours now over the last week and it works very well.!! Thank-you for your reassurance and time taken to explain this to me. I am recommending other people who buy items from USA to use your stepdowns.

  4. Casey

    Thankyou for your time and patience explaining to me why i needed a more powerful stepdown for my kitchenaid. I did not realise this and no one could explain why my other one did not work as i though i bought the right one! The motor draw spikes power use on startup so it needs more power. Its working well on your stepdown and im still way ahead buying a USA kitchen aid with your transformer. Im greatful you were able to help me here. Thankyou.

  5. Chen

    Brought my shaver in and had it tested for the right step down. This was tricky one as the frequency difference impacted the shaver, I really do appreciate this service and time taken to check my everything. Thank-you Kamal.

  6. Des

    My philips morning light is working well with your step down transformer. Nice compant unit the 100w is and pleased ut is a reliable one. Thankyou

  7. Mike (verified owner)

    The technical information/video on the website was excellent so I ordered the step-down transformer for a product I obtained in the USA and wanted to continue using here. Online ordering was easy and the delivery of unit prompt. And what a unit, this is a quality engineered transformer, solid and perfect. Very happy.

  8. Ian (verified owner)

    Thank-you for your advice. I bought the 1000w stepdown and it is working as promised. This transformer is well made and has a strong carry handle. Delivery was quick too!.

  9. Phillip

    Bought your 500w stepdown for my Makita drill and works as promised.
    The transformer is obviously made quite well and the led switch is very handy ias i can turn the transformer off without having to unplug it. Note the spare fuses need to be put aside when you first open the box as they may get lost in the packaging.

  10. Deborah Meagher (verified owner)

    I had a ladies shaver bought in the US not sold here and much better than the ones locally available. I was worried about whether it would work on 50Hz as the specs said 60Hz. The technical advice came back quickly in response to my query. They had actually checked the specs from the model no I supplied and were able to assure me that frequency difference did not matter for technical reasons which were clearly explained. I bought the transformer and it worked fine, although I wouldn’t call it light as someone else commented, it’s a brick. But it does the job.

  11. Lisette (verified owner)

    Great transformer, works well. I received the item within a week, great service thank you

  12. Russell (verified owner)

    Needed a quality stepdown powerful enough to run my Makita hypoid saw ,purchased the 2400watt version ,works great thankyou tortech.

  13. Dave (verified owner)

    So far so good – arrived quick and it feels like a quality, well made transformer – nice materials, nice and solid, the switch has a good feel. And very happy value wise. The team were also helpful – answering a couple of questions I had before and after sale. Working well with my US equipment (monitor speakers, AC/DC transformers). Thanks guys.

  14. Christian (verified owner)

    I purchased a 100-Watt model for use with a photographic enlarger that I bought from a US manufacturer. I was impressed with the video I saw comparing this transformer with a standard market model – the engineers really seem to have taken care to build a high-quality, safe, standards-compliant device. The item arrived within two or three days of ordering, carefully wrapped. The construction is solid, and — most importantly — it works, I can print my photos! The whole experience has so convinced me that I’ve just bought another one for use with a different device, and I won’t hesitate to recommend TorTech to others seeking a transformer solution.

    Great product that works perfectly for my American device. Thanks Tortech!
