Description

[0001] PORTABLE EXTERNAL POWER-SUPPLYING DEVICE [0002]

The present invention relates to an external power supply for consumer electronics, and more particularly to a power supply adapted to be connected to a portable electronic device to serve as a backup power source providing variable power capacity.

Currently, rechargeable batteries are a common power source for many portable consumer electronic products such as mobile phones, laptops, digital cameras, music players, and the like.

To charge such a rechargeable battery, a specific charger is needed to regulate AC power to a specific potential from a power grid. If it is not possible to connect to the power grid, charging is not possible and portable devices that use the battery when the battery is exhausted can not be used.

To avoid this problem, a portable power supply, or "power pack" has been developed. By using this, the user can charge the consumer electronics anywhere, regardless of the possibility of access to the power grid.

Conventional portable power supplies consist primarily of a rechargeable battery packed in an enclosure and a control circuit. Commercialized products have different battery capacities. Portable power supplies with small capacities are typically compact and lightweight, but are not long-lasting. On the other hand, a portable power supply device having a large capacity can be used for a long time but is bulky and less portable. Furthermore, conventional rechargeable batteries have their lifespan dependent on aging and / or frequency of use, and once the battery degrades or reaches its end of life, the entire power supply can not be used.

In view of the cross-section of the prior art device described above, the present invention provides a portable external power supply with variable power capacity. This power supply has a detachably coupled battery unit having a number that can be adjusted according to the user's needs, which means that the overall volume and weight of the power supply can be managed. Since the individual battery units can be replaced, the performance of the power supply can be easily maintained. This helps preserve resources.

To this end, according to the present invention, a portable external power supply device includes a power control module and one or more battery units whose total capacity is variable. The power control module includes a circuit board, indicator lighting set, a first port, a power inlet, a power outlet and the like. The individual battery unit includes a controller, a battery, a second port, and a third port.

When communicating with the battery unit, the control module charges the battery unit through the power inlet for later use. In use, the control module provides power to the portable electronic device via the power outlet.

The control module can charge one or more battery units. These charged battery units can be easily assembled or separated so that one or more battery units can be used for charging according to actual needs. Each battery has its own cycle life, so once any individual battery unit reaches its end of life, the power supply can be replaced by replacing the old battery unit with a new one. Compared to discarding the entire conventional device, this saves cost significantly and is environmentally friendly.
