Not only to look at the capacity, conversion power! The charging treasure is suitable for selection in this way

Zhongguancun online news: Our daily life is indispensable to the charging treasure, but the selection and use of the charging treasure will bring danger. What do I need to be aware of? Let's see what China Mobile has to say.

First, choose the charging treasure, do three looks:

1. Look at the battery cell: Now the battery cell on the market is generally divided into two kinds: lithium polymer battery cell and 18650 lithium battery cell, polymer battery cell because there is no liquid so the probability of high temperature explosion is small, but 18650 lithium battery cell has the possibility of explosion, so pay special attention when purchasing.

2. Look at the capacity: In general, the 5000mAh charging treasure is enough for a smart phone to use, but most people are pursuing large capacity, but the larger the capacity, the greater the manufacturing cost, the higher the requirements for the technical level, and the more likely quality problems. And now many of the extra-large capacity charging treasures sold are false electricity, and the purchase needs to be cautious and try to buy large brands.

3. Look at the conversion power: If the efficiency conversion rate of the charging treasure is below 80%, the loss is very large, and the heat generated by itself is also large, which means that the efficiency is very low, and there may be safety hazards. Therefore, when choosing a charging treasure, be sure to choose a performance conversion rate of more than 80%.

Second, the charging treasure is safer to use in this way every day

1. Do not squeeze and shake the charging treasure: squeezing hard will cause the internal structure of the charging treasure lithium battery to be damaged, resulting in a short circuit, if the battery cell or circuit board is inferior, it may also cause an explosion, throwing, violent shaking is also the case.

2. Do not put in high temperature, humid places: the temperature is too high or too low will have an impact on the charging treasure, especially in the summer, to avoid long-term exposure to the sun, and do not leave the charging treasure in the high temperature, closed car, spontaneous combustion may occur.

3. Avoid overcharging: When not in use, retain a little power and unplug the charging treasure as soon as possible after full charge, to prevent some inferior charging treasures from overheating and then spontaneous combustion caused by no charging protection. In addition, it is best to retain half of the power when idle, and try to charge and discharge once a month to extend the service life.

4. Do not disassemble and transform the charging treasure privately: lithium batteries contain harmful ingredients to the human body, and the disassembly process will cause discomfort to the human body, and may even damage the eyes. In addition, when the lithium battery electrolyte encounters a large amount of water, it will quickly dissipate heat, causing an explosion, so do not disassemble it because of curiosity.

5. Bad charging treasure should not be used again: If you encounter the charging treasure has discoloration, deformation, leakage, or it is easy to be hot, but it can still be charged, it should be stopped immediately, because the above situation is generally caused by damage to the internal structure of the charging treasure, and the corrosion and flammability of the interior will induce safety hazards at this time.
