The Wireless Charger Duo, in black and white. 

This two-in-one charger has a round kickstand-style spot for a device you'd want to keep upright, like a phone, next to a secondary flat pad that can accommodate a smartwatch or second phone, or any combo of two Qi-compatible devices. While they look different, both of the charging surfaces deliver 15 watts of charging power.
