Please use our handy Step-down calculator to determine the correct rating of Stepdown Transformer (please wait for it to load.)

If you know the Watts of your device simply add in the Input Watts W of your device and press enter on keyboard.

If you know the Amps of your device , please put in the Input Amps A and Volts V and press the Update button below.

Note if you device has a motor tick the motor Box

Note: 120v , 115v , 110v for USA devices, 100v for Japan, 220v for Europe

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.

 

Watch Video - choosing the right stepdown transformer: 

 

Please Check these important 5 questions before purchasing your step down transformer:


1. What is the total watts used by appliances to be connected to the Transformer?

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.


2. Does your appliance have a motor ?

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.


3. Does your appliance have a mechanical timing device? 

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


 

Running a 5200 Vitamix on our stepdown:

4. Do you know the Amps of your device? - is so you can calculate the watts required:

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


 

5. Do you wish to use multiple appliances from one stepdown?

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


Still Not sure which Stepdown 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)


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.

 

Running a US amplifier from our 100w stepdown transformer

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:

 

Some examples:

 

Label under the Kitchen aid (or in the manual)

 

Specs at the back of a US Playstation 3 (not slim):


Receivers:

 

On Your Cordless / Fast Charger

look at the power specs on the charger base:

Vitamix - Look at the Amps A behind the machine:

 

Dyson (Look under the Vacuum cleaner):

 

Appliances with power supply units

look at the power supply label Eg: XBOX
