Self driving travel: During self driving travel, the power bank can provide power for devices such as car refrigerators, car vacuum cleaners, air purifiers, and can also charge short distance transportation such as electric bicycles and electric scooters. In the event of a low battery in the car, it can also serve as an emergency starting power source.
Public transportation: When taking long-distance buses, trains and other public transportation, if the number of charging sockets in the carriage is limited or unavailable, the power bank can charge the passenger's mobile devices.
