Common Problem
Q: Why are mobile phones and charging devices hot?
A: Wireless charging is a job that converts electrical energy into magnetic energy and then magnetic energy into electrical energy. Energy will inevitably be lost in the conversion process. All wireless charging will be hot. Usually the phone will automatically stop charging when the temperature exceeds 50 degrees.
Q: Does the mobile phone have to be aimed at the wireless charging coil?
A: Yes, when the mobile phone is aligned with the transmitting coil, the shorter the distance, the higher the charging efficiency, because the energy loss in the middle is less. If the mobile phone deviates from the center of the wireless transmitting device, it can be charged within 6 cm, but because of the long distance, the energy loss is large, so the charging effect is not good, and the heat is higher.
Q: Why can't the mobile phone be charged after being installed in the car?
A: First of all, we must determine whether the mobile phone has wireless charging function. Secondly, determine whether the wireless charging board has a full-voltage power supply, and check the positive and negative poles of the input line, usually red is ACC, and black is negative (ground wire)
