Avoid using the adapter in wet or excessively dusty environments and ensure adequate ventilation during operation.

Recommendations

Use only cables and devices in good condition. Disconnect the adapter from the mains when not in use for extended periods. Do not cover the charger during operation and avoid exposing it to direct heat sources to maintain protection functions and ensure safe charging.
