Dongfeng KR truck parts USB mobile phone charging power socket assembly 3723020-C5105

Designed to charge modern mobile devices efficiently, the assembly features two USB-A ports with advanced fast-charging technology. Each port supports a maximum output of 5V/3A (total 6A combined current) and is compatible with mainstream charging protocols: Qualcomm Quick Charge 3.0, Apple 2.4A, Samsung Adaptive Fast Charging, and Huawei SuperCharge. This versatility allows it to charge iPhones (e.g., iPhone 15) from 0–50% in 30 minutes, Android phones (e.g., Samsung Galaxy S24) from 0–60% in 25 minutes, and small devices like GPS navigators or wireless earbuds at optimal speed. Unlike basic sockets with fixed 1A output, this multi-protocol design ensures fast, stable charging for 98% of consumer mobile devices—critical for long-haul drivers who rely on their phones for navigation and communication

Engineered with safety as a priority, the socket integrates comprehensive protection mechanisms to safeguard both the device and the truck’s electrical system. It includes: over-current protection (10A fuse, auto-resetting after fault removal), over-voltage protection (clamps at 5.8V to avoid device damage from voltage spikes), over-temperature protection (shuts down at 65°C to prevent overheating), short-circuit protection (cuts power in 0.1 seconds if cables short), reverse-polarity protection (blocks current flow if wiring is reversed), and electrostatic discharge (ESD) protection (resists 8kV contact discharge). These features meet IEC 62368 and UL 60950 safety standards, eliminating risks of device burnout, socket melting, or electrical fires—unlike uncertified sockets that lack basic protection

Built to withstand the rigors of truck operation—constant vibration, temperature extremes, and frequent plug/unplug cycles—the assembly uses high-performance materials. The outer shell is made of impact-resistant PC/ABS plastic (UL94 V-0 flame-retardant rating) with a scratch-resistant matte coating, enduring 10,000+ contact tests with no visible damage. The USB port connectors are gold-plated brass (20μm plating thickness) that resists corrosion and ensures low-resistance contact, maintaining charging efficiency even after 5,000+ plug cycles. The internal circuit board is coated with a 0.2mm conformal epoxy layer, protecting components from dust, moisture, and electrical interference in humid or dusty cab environments. Unlike cheap plastic sockets that crack or fail within 6 months, this design operates reliably in temperatures from -40°C to 85°C for 3+ years

Designed for driver convenience and easy replacement, the assembly combines practical features with simple installation. The USB ports are angled 20° upward for easy cable insertion (even with gloves on) and have a soft white LED indicator (dimmable to avoid nighttime distraction) that illuminates when power is active—helping locate ports in low light. The socket includes a built-in cable management notch to prevent cables from tangling or being pulled loose during driving. For installation, it comes with all hardware: a locking nut, rubber gasket (for water resistance), and a 40cm extension wire (if the original harness is short). No specialized tools are needed—installation takes 15–20 minutes: insert the socket into the mounting hole, secure with the nut, plug in the harness, and test charging. Each unit undergoes vibration testing (10–2,000 Hz, 15G acceleration), temperature cycling, and charging performance verification, backed by a 12-month warranty against defects (e.g., port failure, LED burnout, shell cracking)
