Australian Power Supply
Make sure your laptop, alarm clock, phone charger or other appliance accepts 220 – 240 volts (V). If your appliance uses 110 – 120V you will need a step down transformer. Some power supplies for phones and laptops are dual voltage and will accommodate both, but read the label and instructions carefully, otherwise you may cause serious damage.
If your appliance uses 220 – 240V you may still need an adapter to fit in an Australian power outlet. See picture.
The frequency is 50Hz and if your appliance normally takes 60Hz it may not operate slightly slower.
