🇦🇺 Australia to 🇺🇸 United StatesNope, your plugs won't fit. But an adapter will.
And the United States's 120 V is lower than home. Dual-voltage chargers are fine; your kettle will sulk.
What to pack
Plugbert recommends
Type A (US 2-pin) adapter
You need a plug adapter. Plugs from Australia (Type I) don't fit the Type A and B sockets in the United States. A Type A (US 2-pin) adapter fits the listed socket families there. For grounded devices, get a Type B (US 3-pin) adapter for a compatible grounded outlet instead; it does not fit every listed outlet. Socket variants can differ; check the actual outlet and adapter rating.
For equipment requiring earth, choose a Type B (US 3-pin) adapter for a compatible grounded outlet. Check its supported inputs and rated load. A two-pin output cannot provide an earth connection.
Tip: a "universal" travel adapter may be useful for several destinations. Check its wall-side plugs, grounding and power limits against your trip.
Voltage & frequency
🇦🇺 Home
230 V
50 Hz
🇺🇸 There
120 V
60 Hz
The destination may use a different frequency (50 → 60 Hz). Check your device's input rating for the local frequency; a plug adapter does not change it.
Will my stuff survive?
Decode a device labelPhone charger
Basically all modern USB chargers are 100–240V. Adapter only.
Laptop charger
Look for "100–240V" on the brick. It's almost always there.
Camera battery charger
Usually dual voltage. Check the tiny print.
Electric toothbrush
Many are dual voltage, some are not. Check the base.
Electric shaver
Often dual voltage. Often. Check.
CPAP machine
Most modern ones auto-switch, but confirm before you rely on it to breathe.
Hair straightener / curler
Some have a voltage switch. Many don't. Fire is a bad hairstyle.
Hair dryer
Usually single voltage and very power-hungry. Buy a travel one or use the hotel's.
Kettle / coffee maker
Single voltage, high wattage. Leave it home. Buy coffee abroad like a local.
Anything with a heating element
If it gets hot on purpose, assume it's single voltage.
