Explore our top-tier certified switching power supplies and fast mobile chargers, built to exceed global regulatory parameters.
Founded in August 2010, Shenzhen FuYun (RUIYU) Technology Co., Ltd. stands as a premier enterprise integrating scientific research & development, state-of-the-art manufacturing, global logistics, and comprehensive after-sales support for switching power adapters, fast mobile chargers, and medical-grade power solutions.
Strategically headquartered at No.129 of the First Industrial Zone, Lisonglang Community, Gongming Town, Guangming New District, Shenzhen, Guangdong, China, the company occupies an industrial facility equipped with advanced automated assembly lines, high-precision automated optical inspection (AOI), and robust reliability test chambers.
With an active workforce of over 800 employees and more than 30 dedicated executive and technical directors, FuYun (RUIYU) exports 60% of its total output to highly regulated markets across the USA and the European Union, while maintaining rapid growth across Japan, South Korea, and China's domestic industrial sectors.
Our numbers reflect our commitment to supply chain continuity, rigorous quality management, and large-scale industrial execution.
As mobile computing demand scales, our R&D direction converges toward wider semiconductor bandgaps, elevated density configurations, and eco-efficient thermal materials.
Transitioning from legacy silicon MOSFETs to GaN ICs enables our mobile chargers to switch at higher frequencies, shrinking physical footprints by up to 40% while lowering switching losses. This allows ultra-compact form factors to safely deliver 65W to 140W.
Implementing USB-PD 3.1 Extended Power Range (EPR) enables power delivery up to 240W over a single Type-C interface. Supporting Programmable Power Supply (PPS) dynamic voltage steps (20mV/50mA) allows for real-time thermal optimization and battery lifespan protection.
Our engineering division focuses on integrated controllers, drivers, and GaN switches in single-molded IC packages. This minimizes parasitic inductance, reduces electromagnetic interference (EMI) signatures, and ensures smooth compliance testing with EN55032 Class B standards.

| Medical AC/DC Switched Adaptor | 88% - 90% | 0.7 - 1.1 W/cm³ | Clinical monitoring, therapeutic systems | EN60601-1 3rd/4th Edition (MOPP) |
Our Shenzhen-based production facilities leverage smart manufacturing architectures to maintain consistent product quality and reliable delivery timelines.
From robotic Pick-and-Place SMD placement to automated wave soldering and laser casing engraving, human intervention is optimized to reduce assembly variations and maintain defect rates below 150 DPPM.
Unlike typical spot-checking, every power adapter runs through automated thermal stress chambers under full-load conditions for 2 to 4 hours. Automated diagnostic software checks for voltage ripple, thermal spikes, and premature failure signatures.
Located in Shenzhen's Guangming New District, our facility is surrounded by a complete supply chain of high-grade raw materials. This ensures steady access to components and minimizes lead times even during global supply chain fluctuations.
We manufacture power supplies designed to meet the electrical, electromagnetic, and environmental safety regulations of diverse global markets.
