PORTABLE POWER SUPPLY APPARATUS CAPABLE OF RECEIVING AC OR DC INPUT POWER
First Claim
1. A portable power supply apparatus comprising:
- an AC-to-DC power adapter for receiving AC power;
a DC power connector for receiving DC power;
a DC-to-DC power adapter including a first DC power input portion, a DC-to-DC power converting circuit and a first DC power output portion, wherein said first DC power input portion is selectively connected to said AC-to-DC power adapter or said DC power connector for receiving a first input DC voltage from said AC-to-DC power adapter or a second input DC voltage from said DC power connector, said DC-to-DC power converting circuit is electrically connected to said first DC power input portion for converting said first input DC voltage or said second input DC voltage into a first DC output voltage, and said first DC power output portion is electrically connected to said DC-to-DC power converting circuit for receiving and outputting said first DC output voltage; and
an extension power cable connected between said AC-to-DC power adapter and said DC-to-DC power adapter and/or connected to said AC-to-DC power adapter.

Abstract
A portable power supply apparatus is provided. The portable power supply apparatus includes an AC-to-DC power adapter, a DC power connector, a DC-to-DC power adapter and an extension power cable. The AC-to-DC power adapter is employed for receiving AC power. The DC power connector is employed for receiving DC power. The DC-to-DC power adapter includes a first DC power input portion, a DC-to-DC power converting circuit and a first DC power output portion. The first DC power input portion is selectively connected to the AC-to-DC power adapter or the DC power connector for receiving a first input DC voltage from the AC-to-DC power adapter or a second input DC voltage from the DC power connector. The DC-to-DC power converting circuit is electrically connected to the first DC power input portion for converting the first input DC voltage or the second input DC voltage into a first DC output voltage. The first DC power output portion is electrically connected to the DC-to-DC power converting circuit for receiving and outputting the first DC output voltage. The extension power cable is connected between the AC-to-DC power adapter and the DC-to-DC power adapter and/or connected to the AC-to-DC power adapter.
