How to choose mobile power battery?

There are three different specifications of mobile power battery cells, namely: polymer lithium battery, 18650 lithium battery, and AAA nickel-metal hydride battery. In my country, since 2009, mobile power has followed the rise and popularization of mobile phones, digital cameras, camcorders, portable DVD, PDA, MP4, GPS and other digital devices, especially in the era when smart phones are prevalent in our country. In recent years, it has quickly become known and sold hot. The basic working principle of the mobile power supply is to store and transmit electricity, so we can compare it to a large battery that can be recharged and transmitted, and because the mobile power supply is small in size, large in capacity, easy to carry, and cheaper than the original battery. , It can greatly facilitate those who are not satisfied with the original battery capacity and need to use the battery for a long time, and are sought after by business people, young people, and travel enthusiasts. Compared with polymer batteries and AAA Ni-MH batteries, the cost of using 18650 as a mobile power storage and rechargeable battery is cheaper. Therefore, many mobile power processors still use 18650 batteries to improve the price competitiveness of their products. However, in some battery explosion cases exposed in recent years, laptop batteries with 18650 batteries have the most explosions. The use of mobile power sources with 18650 batteries is potentially dangerous in terms of safety. Due to the choice of 18650 batteries The steel or aluminum shell is sealed, and the internal pressure is huge. Once the internal overheating or improper operation causes the internal pressure to be released into the external sealed steel or aluminum shell, its destructive force is like a small bomb. As customers lack knowledge of 18650 batteries and standard application, this is like planting a bomb that can be detonated at any time. Compared with the 18650 lithium battery, the safety performance of the mobile power supply that chooses lithium polymer batteries is practically guaranteed. For example, the leading brand of high-end digital peripherals, Paick, has reached international standards in terms of innovative technology and material appearance. , More importantly, a series of Paick products are selected high-end lithium polymer batteries, which can provide users with high-quality and high-guaranteed products for daily use. Industry experts believe that when customers choose mobile power products, it is best to see whether the battery composition of the mobile power supply is polymer or 18650. If you are not familiar with the safety of mobile power supplies, it is best to choose safe and secure brand products when purchasing. For example, a series of polymer battery mobile power supplies owned by the leading brand of high-end digital peripherals, Paick Paick, should pay attention to the correct use of methods when charging and using, and beware of overcharging and short-circuiting.
