Ease of Use: They are often hassle-free, requiring no Bluetooth connection or app installation. Some active universal models can be turned on with a simple touch of a button and may include features like auto-shutdown to save battery life.
Design and Portability: Universal styluses are often lightweight and feature practical designs, such as a pen clip, a magnetic adsorption function, or a dual-function design that includes a traditional ballpoint pen at the other end.
Rechargeable: Many modern universal styluses have a built-in, rechargeable battery (often via USB-C) to power a fine tip for a more precise writing or drawing experience, with a long working time on a single charge.
