1. We recommend using the QC2.0 / 3.0 Fast Charger Adapter (9V / 1.67A) to charge 2 devices at the same time. 5V 2A is normal charging and the charging speed will be slower.
2. The charging distance is 0-8mm. Please do not install a protective shell that is thicker than 3mm.
3. The watch has temperature control protection. When the temperature reaches 40 degrees, it will automatically stop charging. If the temperature is normal, it will continue to charge.
4. For wireless charging, do not have any metal or magnetic objects in the distance between the center point of the back of the phone and the diameter of 6cm.
5. Lower temperature and faster charging. The charging speed is faster in winter than in summer.
6. Please do not charge in high temperature and humid environment to avoid damage to the circuit.
1 position is centered, 2 shells are not too thick, so these two points are good, would be not hot
