The Market Supervision Administration issued a consumer risk warning. When consumers purchase mobile power supplies, they should choose a reputable regular merchant to check whether the product information is in standard Chinese and consistent with the merchant's introduction.

It is necessary to purchase products that implement mandatory national standards and have CCC certification marks. When in use, check whether the contact of the charging port is good before charging. Use a charger with CCC certification. Its output voltage and current are not less than the charging voltage and current of the mobile power supply. Keep away from flammable and explosive items when charging.

Avoid frequent and long charging, and unplug the charger in time when it is fully charged. Use the original or well-known brand data cable. If the mobile power supply, interface and charging cable are found to be abnormally hot, stop using them immediately. If the shell of the mobile power supply cracks, bulges, and there is abnormal noise inside after falling or hitting, it should also be stopped using it, and do not disassemble it without permission.
