Several small common sense on mobile power
Who all know, whether it is an electric car or a mobile phone, the battery is always a difficult to break the bottleneck". Although Apple's mobile phone has been to love crazy six. A variety of domestic mobile phone is also a superb collection of beautiful things but they, battery has not made much progress. It should be said that the battery has become a mobile phone development of the short board. Mobile phone more intelligent, more demand for energy, a mobile phone on a daily basis need to charge it, if it is going on a business trip or travel, a battery basically meet the needs of demand. This time, you should be determined to choose to buy a mobile power supply.
Now on the market of mobile power can be described as varied, different manufacturers to promote their products are made using different coefficients. A variety of advertising, publicity and overwhelming, and as a consumer of you, know how to choose the mobile power?.
1. Is the polymer core more secure than the 18650?
I believe many people have heard of this argument: 18650 batteries explosion risk, and the worst case of polymer batteries is the fire, will not explode, so the polymer core is more secure than the 18650 core. In theory, this is true, but the reality is not the case. 18650 steel shell packaging, not easy to deformation, after a long period of development, the process is now very mature. Such as Panasonic, Sony, Samsung and other international manufacturers produced 18650 batteries, discharge performance and stability, stable life time and the excellent design of the circuit achieve security, the occurrence of explosion probability is very low. And polymer batteries although theoretically said more secure, but because inside the electricity core lithium ion mushy external use of plastic film packaging, texture is soft, easy deformation, not resistant to impact, so the technical difficulty, on the manufacturer's production demanding. And the current domestic to production of high-quality polymer batteries of only a few manufacturers, different manufacturers to use the overvoltage protection differences greatly, so in the current domestic market, polymer batteries are not necessarily better than 18650 safety.
2. Is the mobile power capacity as large as possible?
Many people will think that the greater the capacity of the battery, the longer the use of time. Search in Taobao's mobile power sales, will find the selling power easily is tens of thousands of Ma capacity. So, the mobile power is the bigger the better it should be aware that the capacity and volume of the mobile power is proportional to the volume, the greater the volume, the larger the. Therefore, in the time of purchase according to their own needs, if not a regular business trip, there is no need to go around with a piece of "bricks". Moreover, now on the market a virtual phenomenon is still very serious, bad manufacturers with high capacity to deceive the consumer, and the actual capacity of the products far below marked capacity. So for the large capacity mobile power can not be gullible.
3. The more expensive the mobile power, the better?
The cost of the mobile power supply mainly includes three parts, the core, the circuit board and the outer shell. In general, the production cost of the mobile power supply of the 18650 electric core is lower than that of the polymer electric core. And the corresponding price range, with 10000mAH as an example, the price of 18650 batteries of mobile power is usually in the 200 to 250 yuan, while the price of polymer batteries in the mobile power price is usually in the 350 to 400 yuan. Of course, some of the design is superior, or a collection of a variety of features of the mobile power, the price is more expensive. If coupled with the brand, the price will be several times higher. For example, the author once saw a 2000mAH mobile power supply in the apple store, the price will be as high as 499 yuan. In short, to measure the pros and cons of a mobile power, from the charging performance, durability, security, conversion efficiency, the appearance of several aspects into consideration, the price is just one of a reference standard, can not fully determine the quality of.
4. Mobile power will be on the mobile phone and tablet PC damage?
Many of my friends are worried about the use of mobile power will cause damage on mobile phones and tablet computers, in fact, charging mobile power and we use mobile phones and other tablet comes with the adapter is the same, not the equipment damage. Measure it will do not cause damage to the two standards, one is the amount of voltage, the second is the voltage stability, if a mobile power can stabilize the appropriate voltage, then it is safe, however, does not rule out various inferior manufacturer will produce a voltage instability and power lines are not suitable.
