When you pick up a sleek 100W USB PD charger, it may look simple from the outside—but inside, it’s a carefully layered structure of GaN switches, thermally-optimized inductors, multilayer PCBs, and smart ICs designed to work in harmony. As a leading China factory PD charger manufacturer, QILIPOWER gives OEM clients full access to both outer packaging and internal engineering customization—without compromising quality.
Let’s walk through what’s inside the QL100WUSB 100W Super Fast Charger:

At the heart is a high-frequency GaN power transistor, replacing traditional silicon. This not only reduces size and heat, but increases conversion efficiency above 93%. The PD controller supports dynamic protocols including SuperVOOC, QC3.0, and PPS, auto-detecting device requirements and delivering optimized current.
The double-layer PCB uses thickened copper traces for high-load current flow, while MLCCs and polymer capacitors ensure voltage filtering, critical for charging sensitive devices like laptops or flagship smartphones.
Protection isn’t an afterthought. There are discrete and integrated circuits for:
- OVP – Over Voltage Protection
- OCP – Over Current Protection
- OTP – Over Temperature Protection
- OLP – Overload Protection
- SCP – Short Circuit Protection
Even under max 100W load, thermal imaging shows the shell surface remains below 50°C due to the internal GaN + ABS composite housing. This makes it ideal for 24/7 charging environments or powering multiple devices on business trips.
From a supply chain perspective, QILIPOWER offers end-to-end customization:
- OEM clients can adjust output specs (e.g., 5V/3A, 20V/5A)
- Select USB-A, USB-C, or dual-port outputs
- Add retail-ready blister packaging or logo embossing
- Choose between EU/US/UK/AU plug types for different markets
With 20+ years of manufacturing experience, QILIPOWER’s factory integrates SMT, injection molding, PCBA assembly, and QC testing under one roof, ensuring lead time, consistency, and traceability—a must for global brands sourcing directly from China factory partners.
For engineers, teardown videos and internal circuit diagrams are available upon request. We invite B2B clients to explore the 80W & 100W GaN charger series to see why our chargers stand up to both stress tests and market demands.
