To clean the HUAWEI power bank, power it off first, and then perform the following steps:

1. It is recommended that you use a dry and soft cotton cloth dipped in medical alcohol to wipe the surface of the shell. To avoid scratching the spring, do not wipe the charging port.
2. The power bank should be stored in a dry environment at room temperature without exposure to direct sunlight. Do not store the power bank at a temperature higher than 45°C.
   

   If you are using a HUAWEI SuperPower Magnetic Power Bank, avoid placing it together with other magnetic objects, as doing so may cause other magnetic objects (such as IC cards) to be degaussed, or placing it in a strong magnetic environment.

3. Insert the charging cable into the power bank correctly with appropriate force, and check that the port of the power bank is normal and intact before use to avoid damage caused by foreign objects.
4. When you are not using the power bank, keep it in a moist-free and dust-free place. Make sure no water or dust can get into the charging port.
5. If you are not going to use the power bank for a long time, or the battery power of the power bank is used up, charge the battery once a month.
6. Remove the charging cable when the power bank is not in use to save power.
