Does the stylus require a power supply? Answer for you!

The stylus requires power, also known as a capacitive screen stylus. There are two types of stylus: active and passive.
1) Active pen: It is a small system with chips, power supply, etc. inside the pen. This leads to relatively expensive prices, but the handwritten input is delicate and has fewer errors, making it suitable for precise operations. Because the market in this area is not large and not done much, the price is expensive.
2) Passive pen: It is a conductive material that simulates human fingers. Handwriting input is relatively rough compared to active pens, with more errors and unresponsive effects. The performance is determined by the capacitive screen itself.
