Rumors have been swirling ahead of Samsung’s Galaxy Note 9 launch about a wireless charging pad known as the Duo, and now Amazon has all but confirmed this unreleased product.

As the name should imply, the Samsung Wireless Charger Duo is capable of charging two devices simultaneously, whether that’s the upcoming Note 9 and Galaxy Watch, or a pair of older mobile devices like the wireless charging-capable Galaxy S8 or Galaxy S9.
