An electronic pen is not a single product. The most common ones in daily life are the touch pens used for writing on tablets, and the flip pens used in classes. Even some medical injection pens are also commonly referred to as electronic pens, depending on the specific context of use. 

Which one do you use for writing and drawing usually? 

If you want to take notes or draw on an iPad or Android tablet, you should mainly choose a capacitive pen or an electromagnetic pen. 

Capacitive pen: The most common type is found in brands such as Apple Pencil, Belkin, and Linky. It works through screen sensing and some of them require charging. It is suitable for taking notes in daily life. 

Electromagnetic pen: Higher in precision, usually does not require charging, mostly used for professional drawing or ink-screen devices, such as the pen for Hanwang e-book. 

How to choose: The key factor is the compatibility of your device. For example, iPad users prefer models that are compatible with Apple Pencil, while Huawei tablets choose the M-Pen series. If your budget is limited, you can choose alternative brands like PowerCore or UGREEN. 

How to choose the time for classes and meetings 

If it is a flip pen used by teachers during classes or for business presentations (also known as a laser pen), focus on the wireless range and the color of the laser beam. 

Function: Supports PPT page turning, black screen display, laser indication. Some models are equipped with Bluetooth and can be connected to a computer. 

Brand reference: Companies like DeLine, Nuovo, Logitech etc. all have mature products. Red light laser is more common, while green light can be chosen for outdoor or large-scale occasions.
