Electronic cigarette and milk tea cup are two different products. Although they all use batteries or charging methods to drive atomizers, there are differences in experience, taste and safety. Here are some of their comparisons:

1. Experience: E-cigarette converts liquid cigarette oil into aerosol through atomizer, simulating the taste and feeling of smoking, while milk tea cup is a device similar to hookah, which generates smoke through suction, simulating the feeling of smoking. Therefore, e-cigarettes are closer to the feeling of traditional tobacco smoke.

2. Taste: E-cigarettes have many flavors, such as tobacco, fruit and dessert. And milk tea cups generally have only one taste.

3. Safety: The smoke oil components of e-cigarettes are mainly additives such as nicotine and glycerol, while the liquid components in milk tea cups generally do not contain harmful substances such as nicotine, so the long-term safety of e-cigarettes has not been fully studied.

To sum up, e-cigarettes and milk tea cups have their own advantages and disadvantages, and the choice of which product mainly depends on personal needs and preferences. If you want to try a novel experience, or try a variety of flavors, then e-cigarettes may be more suitable for you. If you just want a substitute that imitates traditional tobacco and pays more attention to safety, then the milk tea cup may be more suitable for you.
