Blue LED for power output, Red LED for fast charging active.❄️ Premium Components：External MOSFET, iron-silicon-aluminum toroidal core with dual-wire winding, low-ESR capacitors, and 6 ceramic capacitors for high efficiency and low heat.Product DescriptionNeed fast charging on the road, in your car, or during a power outage? This QC4.0/QC3.0 buck-boost module is your answer. It supports virtually all major fast charging protocols and accepts 6-35V DC input – perfect for 12V car batteries, 24V solar panels, or lithium battery packs. The MOSFET reverse protection means beginners don't have to worry about burning the board if wires are crossed. Dual USB-A and Type-C outputs let you charge two devices simultaneously. The Model 3518 adds support for OPPO VOOC and OnePlus DASH. Compact (50×19×12mm) with pre-attached 19.5cm wires, it's ideal for DIY projects. Whether you're an electronics hobbyist, outdoor enthusiast, or preparing for emergencies, this module gives you peace of mind.⚡ Quick Start Guide & Important Tips What It Does & What You Need✅ This module does：Converts 6-35V DC input into fast charging output. Dual USB-A and Type-C ports.❌ This module is NOT：A direct AC adapter (do not connect to 220V). Not guaranteed for laptop charging without proper PD compatibility. You will need：A DC power source (12V/24V battery, car outlet, solar panel, etc.) and a USB cable (C-to-C for Type-C port). New to DIY? Choose our Starter Kit, which includes a C-to-C cable and heatsink. Wiring & Usage Guide1. Wiring：IN+ → power source positive (red), IN- → power source negative (black). Voltage range: 6-35V. Do not exceed 35V!2. Charging：USB-A Port：Connect phone with USB cable. Blue LED on, Red LED on = fast charging active.Type-C Port：Use C-to-C cable. Supports PD/QC4+ protocols.3. Dual Port Usage：When both ports are connected simultaneously, both output 5V (fast charging disabled).⚠️ Important Notes：For low-voltage high-current fast charging (e.g., Huawei SCP), use original or high-quality cables.When measuring charging current, use a low internal resistance USB meter to avoid affecting readings.When input voltage >21V, Type-C port supports 20V/3A output (PD protocol). Common Questions❓ My OPPO/OnePlus phone doesn't fast charge on USB-A?1. Ensure you purchased Model 3518 (VOOC/DASH supported).2. OPPO phones require the USB-A port – Type-C does not support VOOC/DASH.3. Use the original or a high-quality USB-A cable.❓ No PD fast charging on Type-C port?1. Make sure you're using a C-to-C cable.2. Check input power source voltage (6-35V) and current (>3A recommended).3. For iPhones, use an MFi-certified C-to-Lightning cable.❓ Is the module supposed to get warm?Slight warmth during 18-24W output is normal. Our module uses premium components for better heat dissipation. If excessively hot, check:⭕Input voltage (should not exceed 35V)⭕Short circuits on output⭕Adequate ventilation (especially when charging laptops)❓ Can I charge a laptop with this?Yes, if your laptop supports PD charging (e.g., MacBook, MateBook). Requirements:1. Laptop supports PD protocol.2. Input voltage higher than laptop's requirement (24V+ recommended).3. Use C-to-C cable.4. Note: Ensure good ventilation as the module will get warm under high load.Package Includes1 × Fast Charger Module（3516/3518）
