Before you travel, check which plug type your destination uses. A plug adapter only changes the shape of the plug; it does not change the voltage. This guide explains the main types and how to choose.
The main plug types
- Type A: two flat pins, used in the United States, Canada and Japan, among others.
- Type C: two round pins, used across most of continental Europe.
- Type G: three rectangular pins, used in the United Kingdom and Ireland.
- Type I: angled flat pins, used in Australia and New Zealand.
Adapter versus converter
An adapter changes the plug shape. A converter changes voltage. Most modern phone and laptop chargers accept a range of voltages, usually printed on the charger as something like 100-240V, so only an adapter is needed. Check the label on each device before you plug it in abroad.
What to look for
- Number of USB ports and whether it has USB-C.
- Total power output, so it can charge a laptop and a phone together.
- A built-in fuse for safety.
- Compact size, especially if you travel carry-on only.
Tip
Always confirm the plug type for your exact destination on an official or trusted source before buying, as some countries use more than one type.
A power bank for the road
A portable power bank keeps a phone charged when there is no outlet nearby. Check the capacity in mAh, the output ports and your airline's rules; power banks usually go in carry-on baggage.
