1. Through the charging speed and charging time during charging, you can determine whether it is fast charging. 2. Fast charging technology can speed up charging by providing a higher current, so the charging time will be significantly shortened. In addition, the fast charging technology can also charge the device in the best way and improve the charging efficiency by intelligently identifying the charging needs of the device. 3. If your Apple tablet supports fast charging technology, when you use a compatible fast charger to charge, you will find that the charging speed is significantly faster and the charging time will be shortened. In addition, the Apple tablet may display \"fast charging\" or similar prompts during charging, which is also an indicator of whether it is fast charging.
We can see from the display of the device whether it is charged in the fast charge state. When we use the fast charger to charge the device, the words \"Fast charging\" (iPhone) or \"Fast charging\" (iPad) will appear on the device display. If this prompt does not appear, then the device may not have enabled the fast charge function.
