ENGLISH
INDUCTIVE CHARGING
Inductive charging involves mainly through space, the use of an induction
coil which produces an electromagnetic field via a charging station where
energy is transferred to an electronic device which is also equipped with a
corresponding induction coil. The electronic device receives the energy from
the magnetic field and reconverts it into usable electric current which
charges the device's battery and a second induction coil in the portable
device takes power from the electromagnetic field and converts it back into
electric current to charge the battery. This may introduce a potential for
energy loss as the distance created between the device and the charging
board means energy transfer is less efficient.
CONDUCTIVE CHARGING
Conductive charging requires a physical connection between the electronic
device's battery and the power supply. The need for a metal-to-metal
connection between the charger and the device requiring charging is one of
the main drawbacks of this method. To accomplish this without the use of
physical cords connection with the power source, often a charging base.
Conduction based wireless accessories may include changeable backs for
cellular phones, special sleeves and attachable clips. The electronic devices,
fitted with these accessories, are placed on a charging base. The base can
detect when a compatible device has been placed on it and begins the
battery charging process. These charging bases are usually designed to be
able to distinguish between human and metal contact so that there is no
risk of electric shock.
PRECAUTIONS
Please make sure that the power output voltage is within the scope when
charging, otherwise the charging function will not function properly. Keep
the charger away from rainwater, moisture and liquids as it can corrode
electronic components and wiring. Do not place it at high temperatures
which may shorten the life of electronic devices.
