First of all, we need to understand briefly the principle of operation of the charger. Charge the battery according to the principle of the transformer: Turn the high voltage into low voltage, change the alternating current through one direction.

The structure consists of 2 parts which are primary and secondary. In particular, the primary is connected to the input current and the secondary is connected to the current. Thus, whether the circuit is closed or not (ie whether or not to charge), the input circuit is always closed if it is plugged in.

Because of the above-mentioned principle: The power consumption level may be greater if the output circuit is closed (when charging), but it is clear that when not charging, the primary circuit still consumes electricity because it is closed circuit. . The life of the primary circuit will be reduced as the components of this circuit must operate continuously if not removed from the electrical outlet.
