Abstract: A device includes a flexible printed circuit board (PCB) that includes a first battery connection, a second battery connection, and a mechanical coupling apparatus. The first battery connection is for providing a first electrical connection to a first terminal of a battery. The second battery connection is for providing a second electrical connection to a second terminal of the battery. When the flexible PCB is in a first flex position, the first and second battery connections are at a distance where at least one of the first battery connection and the second battery connection is not electrically coupled to the respective one of the first and second terminals of the battery. When the flexible PCB is in a second flex position, the battery is electrically coupled to the first and second battery terminals and is mechanically held in place by the mechanical coupling apparatus.

Abstract: A charging device includes a base and a platform that extends upward from the base. The base and platform may each be configured with wireless charging surfaces to enable wireless charging of a computing device upon contact. The base includes a recess in front of where the platform extends to provide support to a computing device, such as a smartphone. The base's surface may gradually rise until reaching the recess to provide further support to the smartphone and thereby prevent the smartphone from sliding down. The charging device includes female receptacles to enable charging adapters to connect to the charging device, thereby increasing the number of accessories charged with the charging device. Charging adapters can include a laterally extending platform on which, for example, a smartwatch can rest, or a charging shaft that includes a series of electrical contacts for charging external battery devices.
