Have you ever wondered what's inside your Macbook's charger? There's a lot more circuitry crammed into the compact power adapter than you'd expect, including a microprocessor. This charger teardown looks at the numerous components in the charger and explains how they work together to power your laptop.

Fascinating little bit of technology you don't really pay much attention to.

And don't forget the cost aspect.

The bigger transformer will contain more material (ferrites and copper are relatively expensive), and will cost more to ship accross the world. Exchanging that for some passive components, a few semiconductors, and a bunch of engineering hours is probably quite a profitable way to go..

we are talking about 300$ to get a full container from china to europe by ship.
there is nothing to gain here.

even if you only get 1 piece per litre in the container you are only talkiing about 0,4c per piece

Who is doing the transportation for you?

We were paying $2000+ for container from Busan to Hamburg.
