There are many reasons why pencil charges so fast on the tablet, which need to be explained in combination with different situations. In general, the original pencil and the tablet are fully compatible, so it will naturally charge more smoothly when charging. If you use a non-original stylus, then charging with other charging devices will be relatively slow. Therefore, to buy a tablet and a stylus, it is recommended that the original is the best, and the sense of use will be different.
