This spoke page supports the GaN charger sourcing cluster by focusing on certification and quality-control checks importers should confirm before placing bulk orders.
Certification documents to request
- CE and RoHS for EU-oriented orders.
- FCC for the US market when applicable.
- Safety test reports and adapter label specifications.
- PD 3.1 or protocol test summary for high-power USB-C ports.
- Carton label and user manual samples for OEM packaging.
Electrical QC checks
For multi-port GaN desktop chargers, buyers should verify total rated power, single-port output, simultaneous load distribution, temperature rise, short-circuit protection and over-current protection. A product that looks powerful on the listing can still fail under full multi-device load.
Burn-in and aging test
Ask the factory how long each batch is powered under load before shipping. Burn-in testing helps identify unstable components, abnormal heat and early failures. For 470W, 880W, 1000W and 1200W desktop stations, temperature control and internal layout are especially important.
OEM label and packaging checks
Before production, confirm input voltage, output protocol, warning text, plug type, barcode, user manual language and carton mark. For distributors, label compliance is part of product quality, not just packaging design.
