Abstract

The present invention discloses a battery charger base which is a structure having several battery charges stacked with each other and connected to an external AC power. The battery charger base does not occupy an insert hole of a socket, while providing an application of connecting several battery chargers to an external AC power. In the battery charger base, a main body of the charger includes an input plug, a charge rectification circuit, a charge slot, an overload protection circuit and an external AC power socket. The charge circuit is electrically connected to the input plug for inputting an AC power and preventing the circuit from having a load of a large current. The external AC power socket is electrically connected to the overload protection circuit for outputting a stable AC power.

Claims

1. A battery charger base, comprising a main body, an input plug, a charge rectification circuit, and a charge slot, and said charge circuit being electrically coupled to said input plug for converting and rectifying an input of AC power into an output of a required DC power, and said charge slot being electrically coupled to said charge circuit for installing a chargeable battery for performing a battery charge, wherein said battery charger base comprises an overload protection circuit and an external AC power socket, and said overload protection circuit is electrically coupled to said input plug for preventing an input of AC power from having a load of a large current on said circuit, and said external AC power socket is electrically coupled to said overload protection circuit for outputting a stable AC power.
