Macbook charger teardown: Complexity inside Apple's power adapter (2015)
The price list at the bottom [1] isn&#x27;t fair, a company like Apple usually pays more for it&#x27;s components for &quot;higher&quot; quality (usually a probabilistic reduction in failure rate). Things are so bad in the industry that it&#x27;s not possible to get some of the higher rated components because Apple has bought them all.<p>[1] List (from reference 19 on the site):<p><pre><code>    Component                                          Cost

<i>On a side note...</i> I&#x27;ve seen the case where Apple&#x27;s standards for compliance are set using the components they buy the highest grade of - making it even more difficult for external companies to implement compliance. It was bad enough that the standard chip, recommended circuit and recommended testing tools failed to meet their requirements.<p><i></i>NOTE:<i></i> Apologies to any users where the screen is stretched.
