GaN is a selling point, and that makes it easy to over-claim. The audit question is not whether a factory has heard of gallium nitride, but whether the design, the thermal verification and the process records behind the quoted product …
Gallium nitride changed what a charger can be: smaller at the same wattage, cooler under load, and practical as a multi-port desktop device. It did not change how a charger is qualified. A GaN program still stands on platform control, …
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 …
A charger factory can be evaluated on three axes: the platforms it builds, the capacity it can commit, and the commercial terms behind the quotation. Most buyers focus on price and discover the other two later, usually when a launch …
Brands and distributors buy the same charger from several factories and receive quotations that look similar. The differences that matter appear later: whether the specification holds on the second order, whether the documentation survives a customs check……
An audit is not a tour of the showroom. The purpose is to establish whether the process that will build your order is controlled, whether the records exist to prove it, and whether the factory can carry your brand through …
The failure rarely shows up on the incoming inspection report. The adapter meets the output voltage, the enclosure matches the drawing, and the shipment clears. Six weeks later the returns start, because the connector polarity was agreed in a phone …
Your retail window opens in fourteen weeks, the packaging artwork is nearly signed off, and the factory tells you the line is full until after the season. Capacity is usually treated as a detail of the purchase order. In practice …
Two days after the sample leaves Shenzhen it is sitting in a customs warehouse while your launch review waits for a charger nobody can open. Sample shipments rarely go wrong in transit; they go wrong on paper. This guide covers …
The first warranty claim usually arrives three to six months after a launch, when the channel has already sold through the first container. By then the process is either agreed or improvised. Deciding it before the first shipment is cheaper …
A brand rarely launches one charger. It launches a range, and the range is where cost and certification risk accumulate: three wattages, two port layouts, four plug types, and a retail box for each. The difference between a profitable range …
Most OEM charger projects do not fail because a stage takes too long. They fail because two stages run in the wrong order: artwork is approved before the enclosure is frozen, or certification is booked before a worst-case build exists. …
