Q1:Why do you have no data read?Display shows 0 watts.
The digital screen output will be 0W after fully charged the connected device.Thank you for your understanding.
Q2: I tried a 100W rapid charger, but it didnt reach max 100W. Why not continue displaying 100W?
The display power of the cable is the load power of your device, and as a general rule, the load power is the max or peak wattage while charging. For example, your phone supports Max 25W super fast charging, so the 25W is the max wattage or peak wattage while charging. So it will not continue to display 100W.On actual charging, charging is done in a curve, charging wattage increases from 0 to max, reducing to 0 until the device is full.
