Warranty should be claimed if, after following all usage instructions and troubleshooting common issues, the charger exhibits a malfunction that cannot be resolved by the consumer. This includes evident manufacturing defects, such as loose components, circuit board failure without signs of misuse, or if the product suddenly stops working without apparent cause, indicating a manufacturing defect.
