This is a listing for a set of left and right wireless charging pads, as used in the Platinum Sweet Exclusive Seats of the current Mercedes-Benz V-Class. This kit is not sold in Japan and is only available in the original country specifications. Of course, it supports fast QI charging and is compatible with Japanese mobile phones. It has an orange ambient light on the outer frame, which changes to blue when charging. It charges simply by placing your phone on it, making it very convenient. Installation is easy; it connects via a coupler to the ambient light power supply inside the armrest. No modification is required. This product is difficult to obtain in Japan. Please take advantage of this opportunity. We try to keep stock as much as possible, but we are also selling on other platforms, so you may have to wait for the next shipment. Thank you for your understanding.
