Power bank is also afraid of cold and heat

If you have already purchased a Power bank, how should you use it to extend the service life of the Power bank? iwalk lists 8 points to note:

1. Don't wait for the Power bank to be completely empty before charging. Try to keep the power of the Power bank near the half-full state. The smaller the charging and discharging range, the better. Therefore, the best usual usage habit should be to charge after using 50% of the power. Although the number of charging has increased, it is more than the power. In terms of total light emission, the damage to the cell is lower.

2. Power bank is also afraid of cold and heat, so you should pay attention to the operating temperature. The operating temperature of lithium batteries is 0-55°c. When the outside temperature is too low, the battery will work unstable and discharge insufficiently. High temperature will shorten the life of electronic devices, damage batteries and age certain plastics. Such problems are mainly concentrated in winter and summer. In addition, the extreme weather in border areas is worth paying attention to. In daily life, cars, backpacks, etc. are relatively closed environments, because the convection is relatively poor. If the Power bank is placed in the charging and discharging state, it is easy to cause local high temperature and cause an explosion.

3. Avoid charging and discharging the Power bank. The problem of charging and discharging is mainly due to the high load of the circuit board and the excessively high temperature in a short time, which affects the performance and safety. In addition, when we see that the nominal input value of the Power bank is 5V/1A, and the output value is 5V/2.1A, it is easy to make a living out of it, and the internal parts of the Power bank are greatly damaged.

4. Power bank is waterproof. It is clear that the Power bank does not have a waterproof function, so once water gets in, it is easy to make the product unusable. In daily life, it is easy to get water in the Power bank due to moisture, accidentally falling into the water, or using a damp cloth for cleaning, which can cause leakage, short circuit or other failures.

5. Watch out for thunderstorms. There is no problem to use it in the house during thunder weather, but it is not recommended that you walk in open and high terrain to prevent danger caused by the arc generated around the Power bank.

7. If the Power bank is not used for a long time, it should be charged 80% of the power and placed in a dry place. Power bank will consume some power if it is not used for a long time, so it is very necessary to maintain some power. Don't put a Power bank with a particularly low battery in an environment where solar energy is irradiated and water vapor is sufficient. This will seriously affect the service life and sometimes directly lead to overall damage.

8. Choose a Power bank with smart protection. After it is fully charged, do not plug the Power bank into the AC power outlet all the time, especially the low-quality copycat Power bank. If there is no charging protection, just wait to watch the fireworks. When overcharged, the battery casing or pressure valve swells and ruptures, allowing oxygen to enter and react with lithium atoms, and then explode. Using the Power bank with intelligent IC chips with multiple protections such as over-current protection, over-discharge protection, and voltage stabilization protection, consumers do not need to worry about security risks.
