This was one of the first posts by Ken that I saw and it got me hooked. He does such a great job at making tear downs like this interesting and accessible. He has a great companion article with a cheapo charger for comparison: http://www.righto.com/2012/03/inside-cheap-phone-charger-and-why-you.html http://www.righto.com/2012/03/inside-cheap-phone-charger-and... and a comparison of an Apple MacBook charger and a knock-off: http://www.righto.com/2015/11/macbook-charger-teardown-surprising.html http://www.righto.com/2015/11/macbook-charger-teardown-surpr... Really fascinating stuff.
