What happens inside the factory: tooling, inspection gates, capacity and quality control.
A branded fast charger programme can open at 200 pieces per model - but only against a platform whose protocol behaviour has already been tested, thermally characterised and certified. The number is not the qualification; it is the consequence of …
A supplier can present a catalogue, a certificate and a price. A manufacturer can additionally show you the line that will build the order, the tests that run on every unit, and the batch records that make a defect investigation …
China remains the centre of charger manufacturing for a simple reason: the component base, the tooling shops and the engineering talent sit in the same region. The difficulty for a buyer is not finding a supplier but qualifying one, and …
A USB C charger looks simple from the outside: a housing, a board and a connector. Inside a factory, it is a chain of processes where each stage can create a defect that only appears in the field. Understanding the …

An inspection report comes back with a reject quantity, and the next message asks a commercial question disguised as a technical one: can the batch be reworked? The answer depends on the defect, not on the schedule, and the decision …
