A protecting device for an electronic device is provided. The protecting device includes a casing, an energy storage element, and a second accommodating part. The casing has a first accommodating part for accommodating the electronic device. The second accommodating part is disposed in the casing for accommodating a peripheral component. The energy storage element is disposed within the casing, and electrically connected with the first accommodating part and the second accommodating part. When the electronic device is accommodated within the first accommodating part, electric power is transmitted from the energy storage element to the electronic device. When the peripheral component is accommodated within the second accommodating part, electric power is transmitted from the energy storage element to the peripheral component.

Protecting device for electronic device

A battery capacity displaying system includes a host, a display device in communication with the host, and a wireless peripheral device. The display device is connected with the host. The display device is in communication with the host, and includes a triggering element. When the triggering element is pressed, a wireless signal containing a battery capacity data is transmitted from the wireless peripheral device to the host. After the wireless signal is received by the host, a residual battery capacity corresponding to the battery capacity data is displayed on the display device. Consequently, the user can realize the residual battery capacity of the wireless peripheral device at any appropriate time according to the practical requirements.
