Apple's standard charging block is a lot more advanced than you may think
Apple's little, white, rounded rectangle of a wall charger, the one all of us got with our iPhones, may look simple from the outside but internally, it's a lot more advanced than most cell phone or electronics chargers on the market. Ken Shirriff managed to disassemble one and found that there's a lot more than meets the eye.
The internals consist of transistors, resistors, diodes, and tons of other little parts paired with two circuit boards that work together to carefully regulate what kind of power is being output via your USB cord. Ken goes on to explain that even though these are quite a bit more advanced than simliar chargers by manufacturers like Samsung, Apple still makes one heck of a profit on them.
Apple issued a recall back in 2008 concerning the wall block and its ability for a prong to come loose and become lodged into a wall outlet accidentally. Tearing an older version apart next to a new one revealed that there were significant design changes made. Apple didn't go for a quick fix to secure the prong but completely redesigned the wall block altogether. This is a great example of how Apple still manages to focus on the little things, even if you can't see them.

We should applaud all of the sarcastic Captain Obvious' that posted!
A decent product like this is not a stretch but "good" consumerism and half-assed engineering equates to millions of duped buyers and millions of best intentioned
consumers that still overpay for an EE project that simply lacks VC.
Also gotta love how dedicated Apple is about the prongs. It was some sort of engineering marvel to figure out how to make them as sturdy as pretty much every other plug ever made. Way to earn that 500%!
When I look at what the iPhone offers compared to the competition recently, I start to think that Apple may be in trouble. Then I read the articles like this and realize they are quite safe for now.
