Ken Shirriff Takes Apart an iPad AC Adapter and a Cheap Counterfeit

Ken Shirriff:

One safety difference is obvious: the Apple charger has much more insulation. The upper (high-voltage) half is wrapped in yellow insulating tape. Some components are encased in shrink tubing, there are plastic insulators between some components, and some wires have extra insulation. The counterfeit charger only has minimal insulation.

The build quality of the Apple charger is much higher. In the counterfeit charger, some components are visibly crooked or askew. While this doesn’t affect the circuit electrically, it indicates a lack of care in construction.
