1. Using imported chips, the frequency and pulse width are more stable.
2. Double layer FR-4 1.2T-PCB board, PCB board quality is stable and more reliable.
3. Increase the transmission coil, enhance the 28 coil transmission coil, and expand the transmission range.
4. The board supports two power interfaces, TYPE C (supporting forward and reverse insertion) and USB Micro, so you don't have to worry about finding different charging cables anymore.
