Navigating the shift from legacy charging to high-wattage Intelligent Power Delivery.
The industry is rapidly transitioning to Gallium Nitride (GaN) technology, allowing for 65W-100W output in compact car charger form factors, essential for charging laptops and high-end smartphones simultaneously.
Modern procurement demands "Intelligent Identification." Our chargers utilize advanced chipsets to detect device protocols (PPS, QC 4+, AFC) to optimize current flow and prevent battery degradation.
With high wattage comes heat. Our factory prioritizes NTC thermistors and flame-retardant PC/ABS shells to ensure safety in extreme vehicle cabin temperatures (-20°C to 60°C).
Located in the Lisonglang Community, Guangming New District, Shenzhen, Shenzhen FuYun (RUIYU) Technology Co., LTD. has been a pioneer in power electronics since August 2010.
We are a vertically integrated enterprise encompassing R&D, production, and sales of USB car chargers, power adapters, and hairdressing instrument high-pressure core parts.
Our infrastructure supports a global client base, with a 60% market share in the USA and EU, and rapid expansion across Japan, South Korea, and domestic China.

We solve the "Supply Chain Reliability" puzzle for global wholesalers and retailers.
Every market has a barrier. We provide full support for CE, FCC, RoHS, PSE, and CCC. Our medical-grade adapters even meet EN60601 standards, showcasing our capability for high-reliability sectors.
From custom PC/ABS molds to PCB layout optimization, our 30+ management staff and engineering team ensure your brand's unique identity is maintained through private labeling and custom packaging.
With 30 QA/QC staff, we implement 100% full-load burn-in tests. We keep production records for years to ensure 100% traceability for every single unit shipped.
As Electric Vehicles (EVs) become the standard, the internal 12V-24V DC infrastructure is evolving. Our future roadmap includes:
We standardize the SOP, testing each product according to the safety standard requirements and quality system, to make sure all adapters 100% passed before package and shipping. Our lead time is 15 - 20 days after order confirmation.
"High quality standard and best service should make us win to win!"
Quick response to any requirements within 24 hours through our dedicated oversea sales team.
We offer 2-5 pcs free samples to customers for function and compatibility testing before bulk orders.
We provide 0.1% of total order quantities as free backup units to ensure your retail operations run smoothly.
For standard models, our factory lead time is approximately 15-20 days after receipt of the confirmed PO. This includes our rigorous 100% testing phase to ensure E-E-A-T compliant quality.
Yes, all our dual USB car chargers are designed with a wide input range of 12V-24V, making them suitable for both consumer cars and industrial trucks.
Absolutely. OEM and ODM projects are highly welcomed. We can customize the shell color, logo printing, and even the internal PCB design to meet specific wattage requirements (e.g., 2.4A vs 3.0A).
We use high-grade PC material for the housing and include over-voltage, over-current, short-circuit, and over-temperature protection at the chipset level. Every unit undergoes a full-load burn-in test before shipping.
Our facility is ISO9001 certified, and our products carry CE, PSE, CCC, UL, and KA approvals. We also manufacture medical-grade power adapters compliant with EN60601 standards.
