• 🔄 Try another Quick Charge 3.0 cable (even if your unit doesn’t support it, the cable should be high-quality).
• 📱 Connect the charger to another device – if it doesn’t charge, the power supply is faulty.
• 🔍 Check the cable for inflections at the USB-Type-C connector (typical weak spot after the USB-Type-C connector). 6-12 months).
