And lithium-ion polymer batteries are most commonly used in power packs. Battery technology is the key to many new developments: everything from mobile phones to electric cars, so it is very likely that some derivatives will become power banks. The two currently used technologies have slightly different properties: Li-ion: Li-ion batteries have higher energy density, that is, they can store more charges in a given size or volume, and the manufacturing cost is lower, but there are still aging problems; Lithium polymer: Lithium polymer power pack will not suffer from the same degree of aging problem, which is a better choice. And it provides you with high-speed charging enjoyment. The disadvantage is that their manufacturing cost is higher, so they may not meet the budget. 2. Why did you choose the power banks? Smartphones are loaded with a large number of mobile applications, and fast operation is supported by efficient processors. These high-performance mobile devices consume a lot of energy provided by batteries, so reliable mobile accessories are needed to charge the batteries in order to enjoy various functions available on them
