Shared charging cable
Five reasons for the transformation of shared charging treasures into shared charging cables
- The cost is lower than the power bank, and the payback is faster. (The main reason is that the cost is recovered in about 3 months and the daily income is several thousand)
- Repaying the power bank is too troublesome and often there is no place to return it, so I have to return it the next day. (The deduction of 10 yuan and 20 yuan cannot be refunded when the cabinet is full)
- For customer needs, charging generally requires customers to go downstairs to the living room to scan the code to rent. (Detour)
- The battery of the power bank is aging and fully charged. (Regularly organize and distribute the cost of manpower maintenance)
- Long-term full-load overload charging has potential safety hazards of explosion, flammable and explosive (high safety hazard costs)
The key to the difference between a shared charger and an ordinary charger is this password version.
Each device has a number and QR code. Store these in the database of the cloud server system. These QR codes correspond to dozens of password sets. After the user scans the code to pay, the system will display a set of passwords on the page after the payment is completed. This set of passwords corresponds to this device number. After you enter the password, the system will determine whether the dozens of passwords stored in the circuit board match the device number.
When the password is the same as the electromagnetic switch, the chip will be energized. The manufacturer generally pre-stores dozens of passwords in the chip and sets a password algorithm. Prevent users from cracking. When the charging time of the password obtained for the first time is used up, the password cannot be used for charging the second time. These devices themselves are not connected to the Internet, so users feel that the key to connecting the devices is to share the system.
