How to use

Disconnect the device when charging is complete or if the charger becomes warm to touch for extended periods. Use only undamaged cables and ensure the wall socket provides the correct mains voltage for your region.

Usage recommendations

To achieve the best charging performance, use a quality USB-A cable rated for the required current and plug the charger directly into a wall outlet rather than into an extension or multi-socket strip. Avoid exposing the adapter to moisture, extreme temperatures or heavy mechanical stress. For prolonged charging of high-capacity devices, monitor the adapter temperature and allow cooling intervals as needed.
