A small warship PCB lifts off from the charger, and it's carrying some new silicon:

Renesas (Formerly IDT) P9235A-16NDGI wireless power transmitter with a 32 bit ARM® Cortex®-M0 processor

Micro USB for power supply

Not four, not five, but one LED light on the tail.

This charger's layout could be similar to the Gear S3 charging dock, which provides 700 mA of output current at 5 V.
