This Go!Con gizmo costs USD 28, and according to InfoWorld, “actually fits an entire set of plugs into a single device smaller than a pack of cigarettes. It changes its shape like a Transformer toy to fit your laptop plug into outlets in Europe, Asia, Africa, and the Americas.”
The device doesn’t convert the international 220-volt, 50Hz standard into the 110-volt, 60Hz found in the United States. But the power supplies of most laptops already handle this voltage conversion automatically, adds InfoWorld.
Looks like a must-have!
