With the popularity of all kinds of smart phone and tablet computer, more and more people have found that the power of all kinds of digital products, especially the mobile phone's own power, have been unable to meet our need for battery life in everyday use, and so to speak, the emergence of the wholesale power bank, to a certain extent, solved the problem. Then for the consumers who haven't had any contact with mobile power supply, how to choose the power bank manufacturer or good quality power banks?

Whether the power supply is good or not relies largely on the battery cell. It is just like the car fuel tank and drive system, being responsible for the entire mobile power and providing a steady stream of power, and directly determines the quality of mobile power bank. Mobile power supply circuit board can be treated as a control system, which is mainly responsible for power distribution and transformation. It converts the voltage provided by lithium batteries into the standard voltage to provide electricity for charging device.

As is commonly known by everyone, the lithium cobalt oxide is the liquid lithium ion battery, of which the common type is 18650 and square shapes. 18650 battery is 18 mm in diameter and 65 mm in height, widely used as laptop batteries. On account of being used universally with laptop battery, more than sixty percent of the mobile power uses 18650 batteries in today's market. It has a wide range of application and portable size, the techniques are matured increasingly. 

Lithium iron phosphate can be called scientifically as ferroelectric. Compared with other batteries, the biggest difference is the addition of iron element in the positive pole of the battery. Lithium iron phosphate is still in its infancy in recent years and it is a kind of potential material, its safety performance and cycle life is unmatched by other materials, and these are also the most important technology index of power battery. Lithium iron phosphate is non-toxic, good in safety performance and of no pollution. It has multiple sources for raw material and long service life, what more, the price is cheap. It is the ideal of anode material in a new generation of lithium ion battery.

Many people are possibly troubled with a problem that although there has been a big rise in smart phone's configuration, the technology in battery has remained stagnant. But fortunately, the development of external battery can help with our problems to a large extent. When travelling, tourists with a portable external battery charger can recharge their phones or other portable electronics at any time or any place. Gradually, external battery has become a very important accessory, and the products with varied promotions in the market have also been various. Then in the bombing of information, how can customers keep a clear mind in buying their ideal external batteries? 

There are three common mistakes in choosing the external battery.

First, the bigger the capacitance is, the better it will be. The volume of battery is measured by its capacity. More power it contains, bigger it will be.  
Therefore, when choosing, the type of battery is according to our needs. There is no need to take a "bricks" with you unless you travel often. In addition,the immoral phenomenon which some manufacturers deceive customers with high capacity, but actually, the capacity of the product is much lower than labeled. So the selection of factories should also be taken into consideration.

Second, the higher sales of products, the better quality it will have. The products from network channels, due to their price advantage, are often more able to attract consumers to buy. There's a common feature among the highest-selling external batteries in Taobao, which is the large capacity and low price. And it has already ranked the first or second in consumers' consideration. But in fact, these popular products may not stand the test of power quality. In short, consumers should measure the products from durability, safety, efficiency, appearance and other aspects, the popularity is just one of the reference. 

Third, if there will be any damage to the mobile phones or other electronics from using the external battery.
In fact, the same as the power adapter, no damage will be caused to the equipment. But if your external battery comes from those illegal-runned power bank factories, it is impossible to provide a stable voltage and current. It will damage your electronics. So as to protect the safety of equipment effectively,the search of information is necessary.
