Abstract

A battery charger comprises a charging base having an output jacket, an input jacket, and a plurality of battery slots; and a solar panel attached to the charging base above the battery slots via a cover, wherein a pivotal rotation device is connectedly mounted between the solar panel and the cover such that the solar panel is liftable and foldable to various angles. Therefore, the rechargeable batteries can be charged by the indoor commercial electric power or the outdoor solar power for achieving the purposes of saving energy resources and providing the convenience to outdoor use. Meanwhile, the secondary environmental pollution can be avoided for fulfilling the requirement of environmental protection and bringing the best economic benefits.

Claims

1. A battery charger comprising:

a charging base having an output jacket, an input jacket, and a plurality of battery slots; and

a solar panel attached to the charging base above the battery slots via a cover, wherein a pivotal rotation device is connectedly mounted between the solar panel and the cover such that the solar panel can be lifted up or folded down to various angles.

2. The battery charger of claim 1, wherein the cover is made of a transparent material.

3. The battery charger of claim 1, wherein first elastic electrode plates are mounted on both ends of the battery slots, respectively, and second elastic electrode plates are mounted between the first elastic electrode plates, respectively, for forming shorter battery slots.

4. The battery charger of claim 1, wherein two of the battery slots are electrically connected to the input jack to act as charging slots.

5. The battery charger of claim 1, wherein two of the battery slots are electrically connected to the input jack to act as power supply slots.
