Ensuring you select the correct voltage converter for your device / appliance is very important. In order for us to make this easier for our customers we’ve developed a voltage converter calculator which takes information provided by you and returns the recommended voltage converter. If you don’t feel the returned result is correct or are still have doubts there is an option at the last step to contact an engineer with the information you’ve supplied and one of our team will respond and assist you further with your voltage converter needs.

You can also see our handy guide table at the bottom of the page with many USA devices makes and models and the common stepdowns recommended.

    Still Not sure which voltage converter you will need? See our detailed guide table at the bottom of this page

    You may also  contact us with your reply to above questions & we will advise the unit that is required.

    Note: Always look at the INPUT POWER rating – often underneath the bottom of your product on a spec label.

    • USA Equipment is identified as 110v, 115v , 120v  (requires a USA stepdown)    
    • Japan 100V (requires a Japan stepdown ) or 110V  
    • European 220v (requires a Euro stepdown)
    • All Amplifiers and high end Audio equipment should use an Isolated stepdowns to ensure best audio operation.

    Wattage – you need to check the Input Power Rating label on their Product  for the Watts (W) or the Amps (A) figures.If you see the HP (horse power) for a motor multiply it be 746 for watts then add 25% for motor. See here for answers to other common questions.

    If you can’t find the power details in the manual the most accurate way is to look at the spec label under your USA appliance to identify the Input Watts or Amps:

    Product Rating Examples


    Please check these important 5 questions before purchasing your voltage converter:

    Select from our Step downs transformers based on how many watts your device uses. 

    Choose the transformer rated above your devices watts usage.

    E.g: Playstation 3 uses 380 Watts so you need the 500 watt rated stepdown transformer.

    If a motor is included then you should select a stepdown rating approx 25% higher than your motor as a buffer.  

    Motors have a higher power use on the stepdowns and startup currents which need to be allowed for.

    Most motors have a rating plate on them with their Power and Amperage rating.

    If so, how critical is this timing device?The Transformer cannot change the Frequency. It is 50Hz

    If a timing device is included the speed of the device may change due to the frequency change, 60Hz to 50Hz (eg old clocks, motors / fans/microwaves ) Most modern electronic devices should not be affected. Read more about frequency

    Calculated as Watts = Amps x 110Volts  (eg 5 A x 110 V = 550 watts)

    Check total watts of all devices this must be less than the VA (Watt) rating of the stepdown & get a US Powerboard.
