Recommendations

Use the adapter on a stable, flat surface with adequate ventilation and avoid covering it while in use. Match voltage and polarity before connecting to any device. If the adapter becomes unusually hot, emits a smell, or fails to power the device, discontinue use and have it inspected or replaced. For extended battery health, follow the device manufacturer's charging guidelines.
