Explore our flagship certified charging solutions manufactured under ISO 9001 quality controls with complete international safety approvals.
As global vehicle electronics transition from legacy USB-A architectures toward high-wattage USB Power Delivery (PD 3.1) and Programmable Power Supply (PPS) protocols, China's advanced manufacturing ecosystem is driving unprecedented innovation in in-car charging technology.
Modern mobile computing demands have rendered conventional 5V/2.4A car chargers obsolete. Laptops, tablets, high-end smartphones, and portable power stations require dynamic voltage step-up/step-down capabilities ranging from 5V up to 28V (EPR). Dual USB-C car chargers allow simultaneous fast charging for driver and passenger devices without thermal throttling or voltage sag during engine start-stop cycles.
Information Gain Insight: Unlike dual-port chargers with shared internal power paths that drop to 5V/3A combined when two devices are connected, our factory utilizes independent dual buck-boost IC channels that deliver full 45W + 45W or 65W + 30W concurrent output under 12V/24V vehicle battery inputs.
Over 15 years of power conversion expertise in Shenzhen and Shaanxi manufacturing facilities enable us to address critical automotive engineering challenges: alternator load dump transient voltage spikes (ISO 7637-2), electromagnetic interference (EMC/EMI) with vehicle FM/DAB radio receivers, and high-ambient thermal dissipation in sealed cigarette lighter sockets.
Our engineering team mandates automotive-grade synchronous rectification controllers, high-frequency GaN (Gallium Nitride) switches, and flame-retardant polycarbonate (UL 94-V0) enclosures for maximum reliability.
Our R&D team continuously pushes the boundaries of power density, thermal efficiency, and protocol compatibility. Below is the multi-generational technical roadmap driving our OEM/ODM client projects.
Replacing traditional silicon MOSFETs with Gallium Nitride (GaN III) ICs operating at switching frequencies up to 500kHz. This elevates power conversion efficiency to over 93.5% while shrinking internal transformer size by 45%, enabling micro-sized car charger bodies that sit virtually flush with the cigarette socket.
Algorithmic dynamic power redistribution between dual Type-C ports. When a laptop (requiring 65W+) and a phone (20W) are plugged in, smart MCU firmware instantly negotiates power budgets without power interruption or port reset cycles common in legacy chargers.
Engineering 28V/5A power profiles directly from 12V/24V vehicle electrical systems. Designed specifically for high-demand devices such as 16-inch MacBook Pro laptops, portable power stations, and professional video gear operated inside vehicles.

Our customized Dual USB-C car charger manufacturing platforms are tailored to specific global vertical markets and vehicle infrastructure demands.
Fleet vehicles for delivery logistics, telematics providers, and long-haul trucking require ruggedized 24V-compatible dual USB-C power chargers. Our products sustain heavy vibration, continuous operation, and voltage fluctuations from heavy-duty alternators without resetting connected GPS trackers, rugged tablets, or driver handheld scanners.
For global consumer electronics brands seeking private-label or OEM car charger lines, we provide turn-key custom color matching (anodized aluminum, soft-touch matte finish), laser-etched branding, customizable LED ring indicators, and plastic-free FSC-certified retail packaging ready for store shelves.
Uber, Lyft, and taxi fleet operators require passenger-facing charging interfaces that withstand high mating cycles (10,000+ insertions per USB-C port) and feature over-current cutoff to prevent damaged passenger cables from shorting the vehicle's electrical bus.
As electric vehicles feature lower internal ambient noise and sensitive high-voltage DC-DC converters, our chargers incorporate specialized common-mode EMI filtering circuits to prevent any electrical feedback into the EV auxiliary 12V battery network.
Operating 50,000 m² of combined manufacturing floor space across Shenzhen and Shaanxi, FuYun Technology integrates vertical production from PCB surface-mount technology (SMT) to automated ultrasonic welding and 100% burn-in testing.
High-speed Yamaha SMT placement lines equipped with 3D Solder Paste Inspection (SPI) and Automated Optical Inspection (AOI). Every capacitor, resistor, and GaN power IC is verified for positioning precision down to ±0.01mm.
Housing assembly utilizes computer-controlled ultrasonic welding machines, guaranteeing seamless enclosure seals capable of passing rigorous 1.5-meter drop tests and vibration stress testing without structural delamination.
Unlike factories that sample test 5% of output, every single Dual USB-C car charger undergoes 2 to 4 hours of full-load aging under elevated ambient temperature (45°C), followed by computerized final electrical parameter measurement. Barcode serialization ensures 100% component lot traceability.
Navigating complex international trade and safety standard regulations requires a manufacturer with direct certification ownership. We provide full compliance dossiers for seamless customs clearance worldwide.
Mandatory certification for automotive accessories sold within the European Economic Area. Tests verify zero electromagnetic interference with vehicle control units, anti-lock brakes (ABS), and airbag deployment electronics.
Rigorous radiated and conducted emissions testing guarantees our Dual USB-C car chargers operate cleanly without causing radio frequency interference on AM/FM car radios, GPS navigation signals, or cellular reception.
All materials—including solder paste, copper alloys, silicones, and plastic resins—are certified 100% free of lead, cadmium, mercury, hexavalent chromium, PBBs, PBDEs, and restricted phthalates under EU directives.
Full safety reports for North American (UL 2089 car adapter safety), Japanese (PSE), South Korean (KC), and European markets, supported by CB scheme test certificates from accredited TÜV / SGS laboratories.
For procurement directors, product managers, and supply chain executives seeking reliable B2B factory partnerships in China.
Standard housing designs start at just 500 units per production run. This allows buyers to test regional market demand without tying up excessive working capital in inventory storage.
