Universal travel ac adapter allows one to charge up his/her gears. In different countries different types of converters are used. But the universal ones are made in such a way so that people can use it anywhere, despite of which country you are heading for (100V-250V-50/60Hz). This is probably the reason why the Universal Travel Adapters are so popular.
The beauty about buying a universal power adapter for your laptop is that when you decide to upgrade to a new laptop, you wont have to worry about having spare incompatible power supply's laying around. You will already have a replacement chord! If you wanted to, you could keep a chord in your car, and one at home. Having a universal power supply will cut down on the wear and tear of future laptops as well!
