there are plastic insulators between some components, and some
wires have extra insulation. The counterfeit charger only has
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.
