After fully charging, disconnect the device
from the charger. First unplug the charger
from the device, and then unplug it from the
electric socket.
To save energy, unplug the charger
when not in use. The charger does
not have a power switch, so you must
unplug the charger from the electric
socket when not in use to avoid
wasting power. The charger should
remain close to the electric socket
and easily accessible while charging.
