Mobile device charging: In daily life, power banks can charge mobile devices such as phones, tablets, Bluetooth earphones, and smartwatches, ensuring that these devices can be continuously used outdoors or in places without power sockets. For example, when people are shopping, taking a walk in the park, or studying in the library, if the power of their mobile devices is low, they can use power banks to replenish energy in a timely manner.
Emergency lighting: Some power banks have lighting functions and can be used as emergency flashlights to provide temporary illumination for users during nighttime power outages or insufficient outdoor light.
