4. Which type of rechargeable fan to buy?
Depending on individual usage needs, one can make a suitable choice when buying a rechargeable fan.

This type of fan is advantageous for being lightweight, portable, and having both handheld and desktop functionalities. Conversely, if you require a fan to meet cooling needs for family activities such as chatting, watching movies, or having meals, then opting for a large-sized and high-power rechargeable fan is recommended.
