Wireless charging is awesome, but wireless chargers blow. They are so finicky. I have a Nexus 4 and an LG wireless charger, so I know all about this first hand: Take your wireless charging phone, put it on your wireless charger, and it charges, right? Well, only sometimes. The charging coil in the phone and in the charger need to be lined up just right for the power flow to happen. Move the phone 1 mm off center and it stops charging, bump the table it's on and it stops charging, breathe on it funny, and it stops charging.
7YL7 TYLT solves this pretty simply with a charge they call the "TYLT Vu." It has multiple charging coils in the charger, so there really is nothing to line up with.
