Usage: Shared power banks are provided by shared electric vehicles or power bank companies, and users need to rent and use them when they need to charge, and then return them.
Charging time and capacity: Shared power banks often have smaller capacity and can only provide one or a limited number of charges for mobile devices. In addition, shared power banks often maintain high battery levels and relatively short charging times due to their frequent use.
Cost of use: Shared power banks usually require a certain rental fee to be paid
Availability and convenience: The use of shared power banks depends on the distribution and availability of shared electric vehicles or power banks, sometimes requiring waiting or searching for nearby available shared devices
