Switzerland to Hawaii

You need a power plug adapter in Hawaii when you are from Switzerland.

If your devices are not dual voltage, you need a voltage converter to use them in Hawaii.

Hawaii uses a different frequency, so make sure your devices can handle this. Especially moving, rotating and time related devices like clocks, shavers and fans.

Here's why you need an adapter

The outlets and plugs used in Hawaii are A & B. Take a look at the pictures below to see what each plug and socket type looks like:

However, the outlets and plugs used in Switzerland are C & J, so that is why you need an adapter:

Here's why you may need a voltage converter

Hawaii uses a voltage of 120V, while Switzerland uses a voltage of 230V. Because these differ, you need a voltage converter for devices that are not dual voltage.

Nowadays, many electronic devices like hair styling tools or chargers for a laptop, phone, iPad, tablet or e-reader are dual voltage, but you should always double check this before using the device in another country.

You should be able to check the small print on a device or power adapter to see if it's dual voltage or not. If you see 100-240V 50/60Hz printed on the device or power adapter, it is dual voltage and will work with all voltages and frequencies used worldwide. If you don't see this, you need a voltage converter to use the device in Hawaii.
