The present invention relates to a rechargeable battery pack, and more particularly, to a portable cradle-compatible rechargeable battery pack having a mounting function and a charging function of a mobile electronic device.

In recent years, various mobile electronic devices have been developed in various ways. Among them, mobile phones, MP3 players, PDPs, etc. have become representative mobile electronic devices.

These mobile electronic devices have various functions such as MP3 music, DMB broadcasting, video playback, etc. according to the development of technology, and accordingly, batteries also need large capacity batteries.

In this case, when the disposable battery is used, a rechargeable battery pack is provided with the electronic device due to the cost burden of purchasing and replacing a new battery every time the battery is consumed.

However, in terms of portability and design, since mobile electronic devices are pursuing miniaturization and slimming, the standard and capacity of the battery pack that is basically provided with the electronic device are limited, and one or two auxiliary batteries are required for long time use. It is inconvenient to prepare the pack in advance and carry it.

In addition, as the specifications of the battery pack are different according to the type of mobile electronic devices, if you want to carry and use several types, it is necessary to separately prepare a battery pack for each electronic device.

Accordingly, a rechargeable battery pack device that can charge a battery by connecting to a charging terminal irrespective of the type of electronic device has been developed. However, since it is configured separately from the electronic device, it is inconvenient to carry and is merely a function of battery charging. It is true.

The present invention is to solve the problems described above, an embodiment of the present invention is a battery housing that is housed inside the charge battery and the charging terminal and the discharge terminal is provided on one side, and hinge coupling on one side of the battery housing And a mounting cover having a mounting groove for opening and closing the battery housing in the first rotation direction, and the electronic device is mounted thereon, wherein the mounting cover is rotatable in a second rotation direction perpendicular to the first rotation direction to accommodate the electronic device.
