Time based billing:
When users rent a power bank, the system starts timing and charges by hour or minute. For example, some companies may charge a fee of a few dollars per hour.
Charged by electricity:
Some services are charged based on the amount of electricity used by the power bank, meaning that the more electricity a user uses, the higher the fee. This method is usually calculated when the power bank is returned.
Charged based on the combination of rental duration and electricity consumption:
Some services may combine the above two methods, considering both the rental time and the amount of electricity used for charging, to provide a more flexible billing approach.
Fixed rent plus deposit:
Users need to pay a deposit when renting a power bank, and then charge by the hour. When the user returns the power bank, the deposit will be refunded and the corresponding usage fee will be deducted.
Membership or package:
Some companies offer membership services or packages, where users can use the power bank for free or at a lower price for a certain period of time after paying a fixed fee.
Discounts and promotions:
Some services may periodically launch promotional activities, such as first-time use discounts, recommended friend discounts, etc., to attract users.
