A casing device for use with a portable electronic device to attach a peripheral device to the portable electronic device. For example, the casing device is configured to be mounted onto the portable electronic device in various ways. In one example, the casing device can be formed with a first device compartment for removably receiving and supporting a portable electronic device. In another example, the casing device can be adapted to fit in a receiving compartment in the portable electronic device. The casing device can also be formed to have an accessory compartment for removably receiving and supporting a peripheral device, such as an external rechargeable battery. Additionally or alternatively, the casing device can be configured to allow the peripheral device to be electrically connected to the portable electronic device for battery charging and/or data transferring operation. For example, the peripheral device can be formed as an external battery to supply power to the portable electronic device. |
