An accessory device for an electronic device is disclosed. The accessory device may include a unitary body having a first region, a second region, and a hinge positioned between the first region and the second region. When a force is applied to the first region, the first region may bend or pivot at the hinge. When bent, the first region allows the electronic device to slide into or out of the accessory device. Further, the electronic device may slide into or out of the accessory device in a straight or linear manner. Also, the accessory device may further include a power supply designed to supply electrical current to a battery of the electronic device. The accessory device may further include a connector that electrically connects the power supply with the electronic device. The sliding motion of the electronic device prevents the connector from damage by bending.
