Can you lend out a shared rechargeable when the power goes out?

Many people use shared chargers when they go out. Which is a common electronic product that is convenient to use and brings convenience to people. The shared rechargeable battery usually needs to be rented by scanning the code. So if the power goes out, there is no network, and in this case it is generally not possible to rent the rechargeable battery. However, we have developed a rechargeable battery that can be rented even in the event of a power outage.

We built a power supply inside the cabinet and improved the program by adding power-off rental and power-off return, which can solve the problem of returning the rechargeable batteries without stopping the deduction after the power outage in the place or the station is not in business.

So our power bank station can lend out the shared rechargeable when the power goes out.
