Starting from the popularity of smart phones, our desire to upgrade battery technology is more and more strong. Among them, technologies that involve multiple disciplines such as physics, chemistry. Don't say anything else, I heard these two disciplines, you can associate those experts in order to study a technology, becoming the beard, the hair is sparse .
it is because it is difficult, wither manufacturers give alternative methods. One is charging treasure, one is fast charge. Charging treasure portability, but charging efficiency is general, equivalent to bringing a battery.
The fast charge technology is poor, but the charging speed is getting faster and faster, and the blood recovery is very high. These two technologies can only be able to carry out methods, and they are used to these years. Maybe because it is used to it, everyone has become unhappy with the safety of charging treasure and fast charge, until I actually come to us a poison.
Samsung's charging door incident, let the global mobile phone users' charging security awareness is unprecedentedly high, and some people see high-power fast charge worry will explode. The safety problem of charging treasure is also a lot, and a major. During the Spring Festival 2018, Guangzhou flying to Shanghai flights, a passenger's charging treasure spontaneously and smoked.
In 2018, Guangzhou Metro, there is also a problem of charging treasure smoke. On May 16, 2019, the charging treasure of a passenger of Guangzhou 3rd line was smoked. The captured picture was, the entire charging treasure was exploded .
At the end of 2019, the charging treasure of a female college student in Shenzhen was standing in bed for no reason. There is also more, CCTV reporters took a cheap charging treasure to the quality inspection laboratory examination, found that there is also the use of sand instead of charging treasure cells that really put the sand as silicon? This ghost is just the idea, I really don't understand what to be embarrassed or laugh. The researchers also told reporters that there are still some manufacturers to exchange the battery cells with the bad electrical cells in order to save costs.
See here, do you feel that your charging treasure is a little odor? Don't panic, give you a simple way of avoiding a somewhere. From July 1, 2018, the new national standard of charging treasure has been implemented. In the charging treasure package, or charging the treasure, if the word "implementation standard GB35590 / 2017" is labeled, it is the charging treasure through quality inspection standard.
These products can basically use it with confidence. Some users can charge treasures for many years, no new national standards, also marked with GB31241 / 2014 execution standards, which is also used with old national standards, safety may have some problems. The most steady practice, or replace it with a new national standard charging treasure.
If you want to change the new charging treasure, you can pay attention to the type of battery and the two aspects of the battery brand. At present, the mainstream charging treasure uses 18650 lithium battery and polymer electrical cells. 18650 lithium battery, it grows very much like the 5th battery we use, so if you see the dismantling discovery is this battery, don't worry.
This battery is the most mature, the highest conversion rate, the lowest cost, the lowest cost. Tesla's electric cars have also used this type of battery, their electric car panels are composed of more than 7,000 boxes. There are a few of your battery, safer.
In general, a good 18650 lithium battery is in normal use, there is no security problem. However, I also said, because the 18650 battery is currently the lowest cost, the most applicable product in charging treasure products, and it is also more fake. We saw CCTV reporters looking for the "sand battery" to check the qualification department, which is the 18650 lithium-ion battery of the cottage.
When purchasing, you can ask which manufacturer processing of the 18650 battery used by the customer service, general LG, the big factory in force will be safely safe. The other is the polymer battery, and the safety will be higher than the 18650 lithium ion battery. So when we purchase charging treasure online, we can take a look at the product details page, or ask a few more time to choose a few words, try to use the charging treasure of the use of polymer batteries.
As for the charging treasure capacity that everyone is always cared, do not have a good way to test well in general users. The original is, the actual capacity and marked capacity of charging treasure, during charging, due to differences in energy consumption. The battery energy in the charging treasure is charged into the mobile phone.
This process will have a certain degree of discontinuation of the conversion rate of power. As an example, if it supports the charging voltage it supports 3.7V, the lowest voltage of your mobile phone is charged 5V, this is to charge the treasure boost to charge the phone to the mobile phone.
Because of the boosting, the charging process will have power loss, 10000mAh capacity may only be charged (10000mAh ¡Á 3.7V) / 5V = 7400mAh, less than 10,000mAh. So sometimes we will encounter, a 10,000mAh charging treasure, charge a 4000mAh battery phone, and if you can't make it two times.
Not a quality problem. but! Some of the charging treasure of the fake battery may not be completed twice . So, when buying, we still need to choose some of the products of some brand big plants, don't because some manufacturers charge the treasure very cheap, Think that it is cost-effective, blind choice.
Over the years, everyone's consciousness of mobile phone charging security has been increased. It's just like charging treasures such as this type of accessories, maybe some is a little inference because it is not a short-term global large-scale event. I can give the proposal, still I hope everyone can bite to choose the mobile phone manufacturer, or the product of the professional factory.
If you are expensive, but you have a guarantee. Even if you really have problems, we can also find after-sales, don't complain to the same complaints like it.
