Product Description

The GR-LJH-28-QC3 Module is a 28W Quick Charge Module designed as a compact QC3.0 Power Supply Unit with dual input ports (AC 100-240V) and dual high-efficiency USB-A output ports, supporting direct connections to multiple peripherals or embedded systems. It operates within a wide voltage range of 5V-12V and temperature range of -20°C to 60°C, suitable for industrial automation, automotive electronics, and portable devices. The module integrates adaptive voltage adjustment for QC3.0 compatibility, ensuring optimized charging speeds. Key advantages include robust thermal management, overload protection, and 95% conversion efficiency, though it lacks wireless charging support. Featuring a compact design (75mm x 45mm x 15mm), it incorporates short-circuit detection and a 5000mAh backup capacitor for transient power stability. No integrated display or battery, focusing purely on high-performance power delivery up to 28W output. Ideal for applications requiring reliable, fast-charging solutions in harsh environments.
