Portable Charger for Electronic Devices

The present invention relates to a charging device, and more particularly to a portable charging device for an electronic device for supplying power to the electronic device.

In recent years, with the spread of smartphones and the increased utilization of applications using smartphones, smartphones have become a necessity of modern life.

Furthermore, as the size of smart phones of smartphones increases and the use of games and entertainment-oriented app contents using smartphones increases, the consumption of smartphone batteries increases, so-called 'battery shortages' become severe.

In the above situation, when the battery using the smartphone of the integrated battery that is built in the body of the smartphone, the user must carry the charger from time to time to charge the charger by connecting to the outlet.

This is not only troublesome to have a charger every time, but also has the inconvenience of looking for an outlet, it is impossible to charge at all without the outlet.

Because of this inconvenience, many smart phone users are using an external battery that can supply power to the smart phone without connecting the outlet.

As a technology related to the external battery, Korean Patent Registration No. 10-1303627 (2013.08.29) has been proposed. Here, the present invention discloses a charging adapter that includes a secondary battery to enable charging of a mobile electronic device such as a portable electronic device, an emergency electronic device, or a mobile device from the secondary battery.
