1, polymer core is not necessarily safer than the 18650 core
I believe a lot of people have heard of this argument: 18650 core explosion risk exists, and the worst case of polymer core is fire, will not explode, so the polymer core is safer than the 18650 core.
In theory, this is true, the reality is not the case, the 18650 core steel shell packaging, not easy deformation, after a long period of development, and now the technology has been very mature. Such as Matsushita, SONY, Samsung and other international manufacturers produced 18650 batteries, stable discharge performance, life time is stable, and through excellent circuit design to achieve security, the probability of explosion is very low.
Polymer batteries although theoretically higher security, but due to internal lithium ion batteries mushy, external use of plastic film packaging, soft texture, easy deformation, not collision resistant, so difficult for manufacturers the production requirements of high. At present, the domestic is capable of producing high quality polymer batteries manufacturers very few differences, the overvoltage protection used by manufacturers, so in the current domestic market, polymer batteries are not necessarily better than 18650 battery safety.
2, mobile power capacity is not the bigger the better
Many people think that the larger the battery capacity, the longer it will take. In search of mobile power online sales, will find the selling power easily is the capacity of the tens of thousands of ma. So, the larger the mobile power is better?
It should be aware that the capacity and volume of mobile power is proportional to the capacity, the larger the volume is certainly greater. Therefore, in the time of purchase according to their own needs, if not often travel, there is no need to take a piece of bricks everywhere.
Now the market deficiency phenomenon is still very serious, bad manufacturers with high capacity blind consumers, while the actual capacity of the product is far lower than the marked capacity, so for these large capacity mobile power can not believe.
3, mobile power price is only a reference standard
The cost of the mobile power supply mainly includes three parts: the core, the circuit board and the shell. In general, the production cost of the mobile power supply using the 18650 core is lower than that of the polymer core. And the corresponding price range to 10000mAH, for example, the 18650 core mobile power supply price is usually between 200 to 250 yuan, while the polymer core mobile power prices are usually between $350 to $400.
Of course, some outstanding design, or a collection of a variety of functions of mobile power, the price is more expensive. If coupled with the brand effect, the price will be higher than several times. For example, I had seen an apple store 2000mAH mobile power supply, the price will be up to 499 yuan.
In short, a measure of the pros and cons of mobile power, from the comprehensive consideration of charging performance, durability, safety, efficiency, appearance and other aspects, the price is only one of the reference standard, can not completely determine the quality.
4, mobile power will not cause damage to the phone and tablet PC
Many of my friends are concerned about the use of mobile power will cause damage to the mobile phone and tablet computer in the mobile power supply and we use mobile phone tablet and other built-in charging adapter is the same, no damage to the equipment.
The measure of it will cause damage to two standard, a voltage limit, voltage stability is two, if a mobile power can provide a suitable voltage stability, so it is safe, but does not rule out the various inferior manufacturers will produce voltage instability, power line is not suitable to.
