This doesn't particularly fit with the Zolo brand, but Razer did buy the Nexbit and made the Razer phone.
The Razer phone is part of Razer Linda project where you drop the phone into something which adds battery, sound, display.
This is very tangential so quite unlikely but you could be looking at a Razer phone docking station which adds better sound and battery only? Given Anker hasn't ever really got into displays, it could be just a battery with speaker shaped as a dock for the Razer phone? That's one level up from a battery case to add sound?
Personally I'm right against this idea I just invented. Docking station is custom to each phone vs just a BT speaker and a Powercore you can use with many things beyond one phone.
