I saw a question that revealed that it is not a voltage converter, so if you're going between 110/220 VAC countries, you'll still need voltage conversion equipment as needed. This will only handle the plug connectors! Some laptop power supplies will automatically switch between 110/220, it's important to know your equipment!
Important safety tip!
According to one source:
Regions that use ~220–240 V AC:
Europe (all countries, including the UK, France, Germany, Italy, Spain, etc.)
Most of Asia (China, India, Indonesia, South Korea, Thailand, Vietnam, etc.)
Middle East (Saudi Arabia, UAE, Israel, Turkey, etc.)
Africa (South Africa, Egypt, Nigeria, Kenya, etc.)
Oceania (Australia, New Zealand, Papua New Guinea, Fiji, etc.)
South America (most of it, e.g., Argentina, Chile, Peru, except parts of Colombia, Ecuador, Venezuela, and a few others)
Some Caribbean nations (such as Barbados, Saint Lucia, and most of the Lesser Antilles)
⚡ Regions that use ~100–127 V AC instead (different from 220 V):
North America (USA, Canada, Mexico, parts of Central America)
Parts of South America (Colombia, Venezuela, Ecuador, some areas of Brazil)
Japan (100 V, 50/60 Hz depending on region)
