Only use the charger indoors. Do not charge your device during a lightning storm.
Additionally, the following applies if your device has a removable battery:
Always switch the device off and unplug the charger before removing the battery. To unplug a

Accidental short-circuiting can happen when a metallic object touches the metal strips on the battery.
This may damage the battery or the other object.
