Sometimes in retail you will find a thing that combines uses in a way chinese crap does. This is the case with the new Samsung wireless battery pack.
It works as a wireless charging station for both phone and gear
And the kicker is that it cost less than the two combined 
Slim design
Works as a pass-through as well.
Works with samsung gear watches. (Big plus for me)
