Products & Technical Highlights

The product portfolio covers 3W–240W wall plug and desktop power adapters and USB chargers, including GaN fast chargers and SiC power adapters for smart home, security, industrial, and consumer electronics applications. Our self-developed topologies include LLC resonant, active clamp flyback and high-frequency GaN/SiC switching circuits, supporting 24/7 continuous operation for high-demanding equipment. Key specifications:

Input: Universal AC100–240V~50/60Hzwide voltage input

Output: Customizable DC voltage and current; supports PD, QC, PPS, SCP fast-charging protocols

Efficiency: Traditional adapters meetLevel VI; GaN reaches up to 94%, and SiC reaches 96%, reducing product size by over 30%

Compliance:RoHS2.0, REACH, WEEE, EU ERP, US DOE, CEC

Protection: Over-voltage, over-current, short-circuit, over-temperature, surge protection

 

All units pass5kVhipot, full-load aging, temperature rise, and efficiency testing before shipment. ODM services cover customized housing, logo, interface, cable, and structure.

Capacity & Quality Control

Annual production capacity reaches 24 million units. AutomatedSMT, assembly, and comprehensive test lines support both small-batch sampling and large-volume export orders. Multi-stage inline inspection includes AOI optical inspection, functional testing, and full aging screening, with full traceability of raw materials, processes, and finished goods. We implement strict IQC; critical components are sourced from tier-1 suppliers with component alternation management to mitigate supply shortage risks.

Global Delivery

The company provides an end-to-end delivery workflow:

Pre-sales:24-hourtechnical response;7–15 dayssampling lead time

Production:15–30 daysmass production lead time

Shipment: EXW and FOB terms supported; complete test reports and certification files provided

After-sales:1-yearwarranty; technical response within 48 hours. We support ECN management during mass production and track certification renewal to maintain full compliance for the whole product lifecycle.

This framework serves long-term B2B clients across Europe, North America, Australia, and Southeast Asia.
