Samsung's number of devices supporting wireless charging is growing, so it makes sense that the company would offer a wireless charger to handle more than one device for brand fans. If this leaked box shot of the Samsung Wireless Charger Duo (EP-N6100) is real, then here it is.

In his Tweet about it, Roland Quandt from Winfuture.de specifically says it's for the Galaxy Note 9 phone, which will likely be announced at Samsung Unpacked on August 9, but the box indicates it should work with any Qi-compatible wireless phone or device. According to the box, it puts out 25 watts and fast charges, compared to 9 watts for the current, single-device version, the EP-N5100.
