Have you ever wondered why official, brand name device chargers cost so much more than the no-name ones, despite looking almost identical on the outside? Or just how they work?
Ken Shirriff has taken the time to methodically teardown a Macbook, iPad and iPhone charger with detailed pictures and descriptions of how everything works. He also compares them to a no-name charger from Ebay. It’s fascinating, and I know I won’t be buying a no name charger in the future to ensure the safety of myself and my devices.
Bonus: Ken also tore down the Magsafe connector itself, which is more complex than initially meets the eye.
