With 15 kinds of power plugs currently in use across the world, knowing which travel adapter to pack for your trip is key. You certainly don't want to be stuck without being able to charge your laptop, phone, or trusty camera while you're on the road.

To help you, we created this guide to international power plug adapters and voltage converters, so you will know what you should pack in your carry-on for your next vacation.

How do I know if I need a travel plug adapter?

Plug types tend to vary from region to region. In Canada, we use types A and B. A is two-pronged and B is three-pronged. The standard voltage here is 120 V. Luckily, North America, Japan, as well as most countries in the Caribbean and Central America use the same plug types, so Canadians don’t need a power plug adapter when travelling to these destinations.

However, if you are travelling to other regions, such as Europe, Asia, or the UK, you’ll need a plug adapter (and a voltage converter, in certain cases) to use and safely charge your devices while abroad.

Universal power adapters vs. simple power plug adapters

Simple travel plug adapters are used to match a single plug type (from A to O), while universal power adapters can help your devices fit into any type of socket. Universal adapters also come with extras, such as USB ports, allowing you to charge multiple devices simultaneously.

When shopping for the right adapter, consider how often you travel and where you will be going. If you travel to the UK periodically, for instance, buying a good-quality adapter for the Type G plug makes sense. However, if you are an international jet-setter who frequently crosses continents, investing in a universal adapter will save you money in the long run.

Do I need a power plug adapter or a voltage converter?

Depending on what you plan to plug in while travelling, you may need a voltage converter instead of an adapter.

The difference between the two is the electricity – adapters help fit your electronics into foreign sockets, whereas a converter actually changes the voltage in the outlet itself. Nowadays, many modern electronics do not require a converter because they are already dual- or multi-voltage items. However, if you plan to travel with high-powered items like a hair dryer, curling iron, hair shaver, or even an electric toothbrush, you should check the voltage range beforehand.

Where to buy the best power plug adapters for travel

International travel plug adapters are widely available. In Canada, you can buy them at electronics stores like The Source or Best Buy, at large retailers, and even at an airport shop after you go through security. If you need to purchase a voltage converter for your trip, you can find them at office supply stores.
