🧠 WHY THIS VERSION (WITH LOOM) IS BETTER

DC-DC chargers rely on voltage to activate.

👉 Problem: Many modern vehicles drop below 13.2V while driving
👉 Result: Charger cuts in and out = poor charging

🔧 Solution: Included TUR-L Vehicle Loom

⚡ Ignition-Controlled Charging System

✔ Forces charger to activate when engine is running
✔ Prevents charger drop-out in low voltage vehicles
✔ Ensures consistent charging performance

🔒 True Isolation Protection

✔ Cuts power when ignition is OFF
✔ Prevents starter battery drain
✔ Safer than voltage-only systems

📦 TUR-L Kit Includes

🔧 Relay mount with fuse protection
🔌 6m heavy-duty twin core cable
🔌 Anderson rear plug + connector lead
🔩 Full install hardware & fuse taps

🛠 Simplified Install Overview
