What are the precautions when using the Xiaomi 212W HyperCharge Power Bank 25000?

The precautions are as follows:
1. Please fully charge the power bank on its first use;
2. Use an appropriate charger and USB cable (Xiaomi-brand products are recommended) to charge the power bank and other devices via wires;
3. Do not leave the power bank unattended when it is being charged. Remove it from the power supply before going out or leaving for a long time;
4. Once this power bank is fully charged or charges another device to full, unplug the charging cable in time to avoid power consumption of the power bank;
5. When the battery level is not displayed after pressing the battery level check button, it can be because the power bank is in protective mode. Try plugging an external charger into the power bank and check again;
6. When the power bank will not be used for an extended period of time, store it in a cool and dry place, with a battery level of about 25%-50%. To extend its battery life, avoid storing it with its battery fully charged or depleted;
7. The operating temperature of the device should be kept between 5°C and 35°C to ensure optimal performance and safety.
