How to choose a safe and practical polymer power bank

　　With the diversification of smart phones, tablet PCs, digital cameras and other mobile device capabilities, people in various occasions, the use of digital equipment for work and play and a lot of power due to low battery random battery capacity and appears unable to meet these devices normal use, so power bank in recent years, fire up the market, power bank factory produce a wide variety of mobile power,. To really enjoy mobile communications, powerful mobile entertainment, power bank What makes a good? Coupled with the recent burst of poor quality mobile power always bombings on television, let's pick on the purchase had to stay a heart ah! After all, life-oriented, safety first! So choose a safe, stable and easy to use mobile power is necessary.

　　Power bank batteries can be basically divided into four types: nickel-metal hydride batteries, lithium iron phosphate batteries, liquid lithium-ion batteries, lithium polymer batteries.

　　Nickel-metal hydride batteries and lithium iron phosphate batteries, low voltage, large nominal capacity, actual output but low efficiency, compared with the lithium-ion batteries and lithium polymer batteries, without any advantage. If the product description is the use of such batteries, first give up. Buy mobile power batteries mainly to see the material, this is the most important criterion to judge a mobile power good or bad, it is preferable polymer batteries battery A new battery, commonly known as soft bag, the price is high, stable good. In addition, the lithium polymer battery is placed in the fire burning just steaming it will not explode! IPHONE with is this. It is currently on the market the most secure power bank..

　　Security polymer power bank is relatively high, but also relatively long life expectancy, but also did not like the explosion of such security risks caused by problems in the security issue, can be a good guarantee.

　　When the normal use of power bank fevers reason is because the heat in the use of the process, part of the energy the battery can not be 100% of the total output, there will be some form of energy consumption in the mobile power internal circuitry, the efficiency of the high heat will be lower, because the less energy losses in the circuit. Of course, the heat will cause some serious problems, such as: short circuit overheating burning, high temperature accelerated aging components.
