ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a power converting device, more particularly to a power converting device that can convert input power into multiple voltage outputs.
2. Description of the Related Art
A conventional power converting device is used to convert alternating current input power into direct current output power. In one example, the conventional power converting device converts an external 110V/220V alternating current power into a 5V direct current voltage output suitable for application to an electrical appliance. However, since the conventional power converting device only provides a single converted voltage output, another power converting device is needed if the electrical appliance requires a 6V direct current voltage output. Moreover, the conventional power converting device can not be used outdoors where commercial external power is unavailable, thereby resulting in inconvenience during use.
SUMMARY OF THE INVENTION
Therefore, the object of the present invention is to provide a power converting device that can convert direct current input power into multiple voltage outputs.
According to the present invention, a power converting device is adapted for use with a battery pack. The power converting device includes a housing formed with a battery receiving space that is adapted for receiving the battery pack therein, a battery connector mounted on the housing inside the receiving space and adapted to be connected electrically with the battery pack when the battery pack is disposed inside the battery receiving space, at least two output connectors mounted on the housing and accessible from an exterior of the housing, and a power converting circuit mounted inside the housing and connected electrically to the battery connector and the output connectors. The power converting circuit is adapted to be connected electrically to the battery pack via the battery connector, and is adapted to convert electrical power of the battery pack into at least two voltage outputs that can be tapped at the output connectors, respectively.
