The DY-11 Repair Power Cord is a specialized diagnostic cable designed to power mobile phone motherboards directly from a DC power supply. It allows technicians to simulate battery voltage and monitor current draw without needing a physical battery, making it essential for logic board repair, short-circuit testing, and device diagnostics during refurbishing. ✅ Key Features: 📱 Direct Power Simulation: Replaces the battery during repairs by supplying safe, stable power directly to the motherboard through battery connector terminals. 🔍 Diagnostic-Ready: Enables testing of boot current, power-on issues, and short-circuit detection—ideal for troubleshooting dead or non-booting phones. 🔌 Multiple Connectors: Typically supports a range of iPhone models (e.g., iPhone 6 through 13/14), using labeled flex connectors for each model’s battery port. ⚡ Clean Power Flow: Designed for low resistance and stable voltage transmission when paired with a professional DC power supply. 🧰 Lab-Grade Durability: Built with high-quality wires, reinforced tips, and anti-interference shielding for consistent performance in repair shop environments. 🧲 Color-Coded Wiring: Easy identification of positive and negative terminals to avoid reverse polarity during use.
