## Long description

3-in-1 Qi2 wireless charging station designed for Apple iPhone, Apple Watch and TWS headsets.

The Watch Charger is compatible with current Apple Watch models. MagSafe magnets and the Qi2 standard provide reliable alignment and efficient wireless charging. An UltiMag ring is included to enable magnetic wireless charging for phones without MagSafe or Qi2, making the station compatible with many recent iPhone, Samsung and other Qi-capable devices.
Advantages
The charging station supports simultaneous wireless charging of three devices and offers flexible use of the detachable Apple Watch charger. Qi2 and MagSafe magnet alignment increase charging efficiency and stability. The device supports both landscape and portrait phone placement for viewing content or reading messages.
