A common mistake of mobile power supply

Smart phone configuration is higher and higher, battery technology has been little progress, every smart phone users deeply felt the lack of mobile phone battery life. And at that time, mobile power supply becomes a very important accessories. On the market of mobile power products is multifarious, various manufacturers to promote their products is also constantly preaching various concepts to consumers. So, in this bombardment of information, you can also keep a clear head, rationally choose and buy mobile power? Here the author is to count the mobile power of choose and buy some common pitfalls.

Test report authority

Mobile power has not been a national unified authentication standard, all brands of so-called inspection report, 2013 is the third party institutions and enterprises consultation between the test items. Therefore have a test report may not necessarily said the product is qualified, at least from a mobile power supply is the most important technical indicators: discharge curve analysis to know the value of how many products.

Polymer batteries safer than 18650 batteries

18650 batteries and polymer batteries

Believes that many people have heard of this story: 18650 batteries exist the danger of explosion, and the polymer batteries in the worst case is a fire, do not explode, therefore the polymer batteries safer than 18650 batteries. Actually saying is so true in theory, but the reality is not. 18650 batteries using steel shell packaging, not changeful form, after long-term development, the technology is very mature now. Such as panasonic, SONY, samsung and other international companies' 18650 batteries, stable discharge performance, battery life is smooth, and through excellent circuit design to achieve security, explosion probability is very low. And polymer batteries, although theoretically security is higher, but the internal lithium ion batteries is squishy, external use aluminum-plastic film packaging, texture is soft, easy to deformation, not resistant to impact, so technology difficulty is big, high production requirements of the manufacturer. And can produce high quality polymer batteries to the current domestic manufacturers are few and far between, different manufacturers adopt overvoltage protection difference is very big, so in the domestic market, polymer batteries do not necessarily safer than 18650 batteries.

The greater the capacity, the better

Because of the influence of capacity is mobile power use is the most important parameters of the length of time, so many people will think, the greater the capacity of mobile power supply, the better, but this time, on taobao search sales ranking of mobile power supply, you can see, before the capacity of millions of mobile power supply are too weak, frequently is twenty thousand or even twenty thousand ma. Then, mobile power supply is bigger is better? More than ten thousand ma mobile power supply usually have 5 or 6 batteries as we know, mobile power supply capacity and is proportional to the size, capacity, the greater the volume is sure. Therefore, when the choose and buy according to their own needs, if not travel, it is not necessary to run around with a piece of "brick" and virtual target phenomenon on the market is still very serious, how to identify empty mark, please refer to the separate Small make up teach you how to identify the mobile power "), deceive consumers, bad vendors with high capacity and the actual capacity of the product is far lower than the marked capacity, so for these large capacity mobile power not credulous.

Good sales job

Network channels due to the price advantage, tend to attract consumers to buy. And we see that the current taobao's biggest-selling mobile power have a common characteristic, that is the large capacity and low price. And this has become a main considered factors are consumer choose and buy. In reality, however, mobile power supply quality may not stand the test. Chinabyte did a issue of taobao sell mobile power transverse review, test results show that the low price of high capacity mobile power products there are all sorts of problems. So when buy, should not blindly follow the sales network, to keep rational mind, try to select some popular known as the brand, the probability of such problems will reduce a lot.

The more expensive

Said the price is too low in front of the mobile power supply is not worth the choose and buy, so does that mean the higher the price the quality is better? Now on the market of mobile power source product price difference is very big, cheap dozens of yuan, expensive hundreds or even thousands of yuan. Actually the cost of mobile power supply is not so high, we think of including batteries, circuit board and the shell of three parts, in general, use 18650 batteries, mobile power production cost is lower than the polymer batteries, mobile power supply. And corresponding price range, I can give a reference here, 10000 mah, for example, 18650 batteries, mobile power prices usually in 100 yuan to 130 yuan, and the movement of the polymer batteries power prices usually in 150 yuan to 200 yuan. , of course, some outstanding appearance design, or a collection of a variety of functions of mobile power supply, prices are more expensive. If coupled with the brand effect, the price will be higher than several times, in short, to measure the pros and cons of a mobile power supply, from charging performance, durability, security, conversion efficiency, appearance and so on comprehensive consideration, the price is just one of the reference standard, can't decide the quality completely.

Whether the damage

A lot of friends are worried that the use of mobile power supply will cause damage to mobile phones and tablets, in fact, mobile power supply, and we use the cell phone tablet own charging adapter is the same, will not cause damage to equipment. Of course, if encounter some fake the inferior mobile power supply, small factory can't provide mobile phone and tablet, stable voltage and current will endanger the digital equipment. Therefore, when buying mobile power must choose some popular known as the manufacturer, so as to effectively guarantee the safety of the equipment.
