Notebook external battery

The present invention relates to a battery, and more particularly to a notebook type external battery.

In order to reduce the weight and carry it out, the notebook computer tends to make the notebook thinner. In contrast, the battery equipped with the notebook itself is also necessary to be thinner. However, due to the size limitation of thin batteries, their storage capacity is small. Therefore, when the notebook computer is used for out-of-home use and lacks the supply of external power, the notebook computer cannot be used for a long time, thereby reducing the notebook computer. Practicality.

In the conventional technology, in order to solve the above problem, a thick battery having a large amount of power is used, so that when the storage capacity of the thin battery is exhausted, the thin battery can be removed from the battery connector of the notebook computer, and then thick. The battery unit is connected to the same battery connector to provide power to the notebook.

However, some thin batteries are built into notebook computers and cannot be removed. Therefore, notebooks with built-in thin batteries cannot use the above method to extend the life of the notebook by removing thin batteries and then installing thick batteries. . Therefore, some notebook computers with built-in thin batteries must add a battery connector to the outside of the notebook computer to allow external battery to extend the life of the notebook. However, such an approach often leads to an increase in the cost of the notebook computer.

Therefore, how to make the thick battery directly connected to the notebook computer without increasing the cost is a very important issue. Under this premise, the inventor of this case deeply felt the need to develop a new notebook computer external battery to improve the above problems at the same time.
