Always use certified chargers from trusted brands and inspect cables for wear or fraying. Keep connectors clean and dry, avoid charging in extreme heat or dusty environments, and verify that your device and cable support the same charging standards. Using the right-rated charger reduces wear on the battery and helps maintain long-term performance.
