Mobile phones and electronic products have penetrated into our lives. How to use electrical appliances without a power source has also become the focus of our attention. Let us enter the world of power banks! Nowadays, mobile phones have become an indispensable part of people's daily life. Frequent use brings about insufficient power, so mobile power sources have emerged. Trendy people can use mobile power to charge when they are away from home. Most of the mobile power is compatible with all USB charging devices and supports mobile phones, tablets, cameras and other devices. It is definitely a must-have tool for going out and traveling.

    The core components of power bank  mainly have two parts, one is the medium that stores electricity, and the other is the medium that converts other energy into electricity. Since many customers are concerned about what brand of mobile power is good, the quality of the battery can be used as one of the important standards to measure the quality of mobile power. Polymer lithium ion batteries are more expensive than ordinary lithium batteries. However, the advantages of high capacity and small size of high-capacity polymer lithium batteries make it gradually replace ordinary lithium batteries.

    Generally speaking, the power of the newly purchased mobile power bank is very low when it is used for the first time, so it is best to charge it fully before using it for the first time after purchase, which will help improve the performance of the built-in lithium battery of the mobile power bank. It is normal for the power bank  to generate some heat during charging or discharging. If the power bank  is very hot, there is a problem. Therefore, the purchase of mobile power must have overcharge and overdischarge circuit protection, and the battery must be produced by a regular power bank manufacturer. It is best not to consider the battery made by a small factory.

    In addition, when charging the mobile power itself, the general time is 2-5 hours. After it is fully charged, it is best to unplug it from the socket in time, and do not continue to charge it for a long time after it is fully charged.

    The ultra-large capacity of power bank will become the trend of mobile power development in the future. The larger the capacity, the longer the battery life. However, the capacity is large, the ratio of volume to weight is increased, safety issues are also prominent, and the charging time will be increased accordingly.
