Patent ID: 10824202

Abstract:
Disclosed is a battery sleeve case for a portable electronic device (e.g., laptop computer or electronic tablet device) that includes an elastic polymer frame structure that extends around a perimeter of the sleeve to provide cushioning or padding to the sides of the device. Front and back face side panels are attached to opposing sides of the frame structure, via stitching or some other suitable means. The frame structure may be formed of injected molded ethylene vinyl acetate (EVA) or other suitable material. The side panels may be laminated with fabric, with a front face side panel being flexible and cushioned and including one or more access flaps. The back face side panel includes a rechargeable battery housed within a battery compartment defined by a semi rigid outer panel, which may be formed of compression molded EVA or other suitable material. The rechargeable battery is electrically coupled to external and internal electrical interfaces. One or more inductive charging components are provided to enable wireless charging of the portable electronic device when the device is in the protective case and wireless charging of the rechargeable battery. A user accessible activation control enables power flow to and from the rechargeable battery. The case allows the portable electronic device to be charged both in and outside of the case.
