Users when charging treasure of choose and buy, often focus on the appearance of the charging treasure and rechargeable battery capacity, rarely to analyze the internal structure and the working principle of charging treasure, in recent years, there are a lot of bad manufacturers use unqualified material charging treasure, charging treasure safety accidents occurred frequently, there are a lot of safety accidents can be avoided, If you can understand the charger in depth before you buy it, you can avoid buying bad products.
At present, the common charge bank on the market can be roughly divided into two categories, one is polymer charge core charge bank, the other is lithium battery charge bank.
1. Polymer Charging treasure: Polymer for polymer lithium ion battery charging treasure, the volume of polymer lithium ion battery is very small, very suitable for making carry charging treasure, and polymer lithium ion battery plasticity is extremely strong, can make different shapes depending on the designer's scheme and, in order to meet the design requirements and use requirements, but also stronger than ordinary lithium battery safety.
2. Lithium battery charging treasure: the lithium battery charging treasure here refers to the use of 18650 lithium cell charging treasure, lithium cell due to a long production history, so the production process is more mature than polymer battery, the cost is relatively low. However, because 18650 lithium cell can be recycled, it is often used by unscrupulous merchants for renovation, which leads to the safety rate of lithium cell battery has not been high, and problems occur frequently. Typically, they are larger and therefore heavier than polymer batteries.
At present, the charge bank on the market is transitioning to polymer battery, and the common lithium battery charge bank will eventually withdraw from the historical stage.
We also try to choose the polymer battery when choosing the charger, which is not only lightweight, stable and safe, but also has a longer service life.
