What are the precautions for using the power bank? First, let’s briefly understand the power bank, which is also called "external battery", "external battery", "backup battery", etc. The concept of power bank is developed with the current popularity and rapid growth of digital products. Its definition It is a large-capacity portable power supply that is convenient and easy to carry.

    Precautions for the use of power bank:

    1. Do not drop, knock or shake the power bank. Because the user unintentionally knocks the mobile power source violently, which causes the internal structure of the lithium battery to be misplaced. The lesser consequence is a short circuit, and the more serious is that the lithium battery spontaneously ignites or even explodes!

    2. Do not put the power bank in the water. The mobile power supply has no waterproof design. If it is accidentally put into water or cleaned with a damp cloth, it is easy to cause leakage, short circuit or other failures. The user should wear rubber gloves to pick it up, and remember to grab the power bank with bare hands in a hurry.

    3. Avoid long-term exposure to sunlight or rain. The ideal place for the mobile power supply should be a dry and mild environment. If it comes into contact with liquid, it is very easy to cause accidents due to corrosion of electronic components and circuits! High temperatures will shorten the life of electronic devices, damage batteries and age certain plastics. At the same time, try to avoid using it outdoors in cold or low temperature. The operating temperature of a general lithium battery is 0-55 degrees Celsius. Too low temperature will make the battery work unstable and insufficient discharge. Generally, the working temperature of lithium-ion battery is 0~35℃. Use mobile power for emergency charging. Try to avoid using it when the temperature is too high or too low. If the temperature is too low, the discharge will be insufficient. If the temperature is too high, the battery will be shortened. Service life.
