<p>A portable power supply apparatus (100) comprises a casing (1), a control circuit board (2), a direct-current output interface (7) and/or USB output interface (8), a power generator (3), a rotary disk (4), a handle (5), and a battery pack (6). The power generator is mounted inside the casing and has an output terminal electrically connected to the battery pack, an input shaft of the power generator is fixed with the rotary disk, a surface of the rotary disk is opened with a through slot (41), an end of the handle is clamped in the through slot and is pivotally connected to two inner sidewalls of the through slot, a receiving slot (1a) for receiving the other end of the handle when the handle is folded is provided at an end, near the rotary disk, of a lower bottom surface of the casing, and the battery pack is embedded in the casing and is electrically connected to the control circuit board. The battery pack comprises at least two batteries (61), and the two batteries are connected to each other in parallel. The power supply apparatus has advantages such as a small volume, high portability, and manual power generation.</p> |
