The wireless charging kit is composed of an replacement backplate and wireless charging pad. The new backplate will presumably add inductive coils to the rear of your Galaxy S IV which are connected to the Galaxy S IV via the gold contacts you see above. For all you desk jockeys out there, this will be an essential part of your kit–no plugging and unplugging your device from USB just to use it. Simply pick it up or place it back on the charging mat whenever needed.
Samsung’s official wireless charging kit will be available starting week 17 of release with a price tag of $49.99. The kit that’s been leaked is white, but we expect that Samsung will release a matching kit for the black Galaxy S IV as well.
