Coquettish Rebirth

Such a small thing as a power bank is really not a high-tech thing.To put it bluntly, it is to use some lithium battery cells, such as the most commonly used cells such as 18650, and then add a pressurized voltage drop board.What is an 18650 battery cell?The main meaning is that such a cell with a diameter of 18mm and a length of 65mm is a thing similar to a battery.Then such a thing like the AA battery has a capacity between 5 and 1200, and the unit is of course mAh. Generally, the price below 3000 is less used, and the price is not so low. After all, it is because of less use. Low Yield.Then 2000 and 2800 are more expensive, and they are less used. According to Jia Hongjian’s experience, the most used ones are 3000, 2000, 2200 and 2400 mAh, although it looks like this AA battery. Toys can have a higher capacity than the lithium batteries used in mobile phones by Jia Hongjian and the others, but this is actually not the case!

The main reason is that the 18650 battery is actually 3.7v for input and output, while the mobile phone uses 5v!Jia Hongjian’s mobile phone uses the 5v1a usb standard that is the standard of later generations. No one uses it like this these days, so it means that Jia Hongjian and the others have created the standard. Changed to a convex miniusb interface.So speaking of it, a 2000mAh 3.7v charging power source, if it needs to step up to charge a 5v mobile phone, it must be calculated according to the voltage of 5v.The capacity is not 2000!The overall calculation is that 3.7 needs to be multiplied by 2000 and then divided by 5, that is, in fact, the capacity is 5 mAh under 1480v voltage.Such a 2000mAh 18650 battery cell is actually barely enough to fully charge the sphone's battery.But the problem is, this charging is not 100% conversion efficiency!Both the mobile phone and the power bank will heat up when charging, which will cause loss!There is electrical energy converted into heat energy, so according to Jia Hongjian's understanding, it is not bad if the conversion efficiency can generally reach more than 80% or even 85%!That is to say, in the end, if the sphone is completely out of power, a 2000mAh nominal 18650 battery can only charge the sphone to 8% full!Then the 18650 mAh charging treasures of later generations are actually the 3.7v capacity added after the parallel connection of 1000!It is said to be 4 mAh, maybe it is just such a 2600 parallel connection of four 18650 mAh!

On the surface, it seems that parallel connection to increase capacity seems to be a good thing, and there are many cheap charging treasures like this on X treasures in later generations.But in fact, the threshold is not so low to do well!Why do you say that?Because in detail.There is also a problem if the batteries in the power bank are connected in parallel, because there is a problem of synchronization.Just how to make several batteries use up the same power at the same time?If one uses up 65% and the other uses up 64%, does it become 65% charged to 64%?This will actually start "infighting"!Such an infighting.Needless to say capacity is definitely susceptible too!So in terms of synchronization, we have to get the circuit board.Still have to do design!But then again.Such a power bank or something like that is not a problem for manufacturers like Biyadi.Generally speaking, Jia Hongjian felt that making a power bank with a nominal value of about 4000 mAh would be enough.Although it is said that the initial capacity of charging treasures that appeared in the next few years in history is nominally in the range of 6000 mAh to 18650 mAh, but Jia Hongjian knows that 300 has a charging and discharging life of 18650 mAh. Second-rate!So relatively speaking, the parallel connection has a large capacity, and can charge the mobile phone more times when there is electricity. Then, the quality of such a charging treasure is better, and can it be used for a longer time?Of course, we are produced by a regular factory, and the price is usually more expensive than the 2600 produced by our own. A 30 mAh one costs 10000 yuan, so a 120 mAh one costs about 200 yuan. It's going to be [-], and in the end, add it in a mess, plus Huaxia Hi-Tech has to earn some licensing fees, right?Doesn't it cost [-] retail price to come and go?After talking about such a thing with Biyadi, Wang Chuanfu was quite happy. After all, Biyadi has become one of the official accessories manufacturers certified by Huaxia Hi-Tech!They also make money!

Speaking of such a thing as official accessories, it is actually a very profitable thing.Like Apple in the previous life, it was certified with various manufacturers, and then licensed to make accessories for Apple mobile phones, such as earphones and charging cables for Apple mobile phones.But such a thing, because it is authorized, so the price will be relatively expensive.Jia Hongjian thought for a while, except for the power bank, it seemed that there was not much need to charge extra for earphones or charging cables.Their mobile phones have been sold at a low price, so why do they make high-priced accessories like Apple?So basically it’s enough to sell it at the cost price, since it’s not a high-end thing anyway.It's just that their things use such a temporarily unique interface of miniusb. There is no need to buy a charging cable for 20 or [-] yuan.

To be honest, after Jia Hongjian paid attention to matters such as power bank and mobile phone optimization, he didn't put much energy on these matters.After all, he is the boss, as long as he grasps the general direction, he really doesn't have to follow the specific matters so closely.Besides these things, where else could he focus his attention?Is it how mobile phones are marketed?This is not the case. In fact, for Jia Hongjian, although such a mobile phone has not yet started to be sold, the specific plan has almost been made, and the next thing can be done step by step.What he wants to care about is actually the matter after such a mobile phone is released, and even the next generation of mobile phones!

For example.Our mobile phone is so expensive, isn't it a bit limiting our own reservation consumer group?You must know that our mobile phone is not an Apple iPhone!There is a reason why Apple's iPhones are so expensive!Apple wants to make money from both software and hardware, and it is for the immediate benefit, so of course it will be expensive!But Jia Hongjian was different. With such a marketing plan, Jia Hongjian did not pay much attention to how much money he could get each year, but more on creating his own dynasty!He wants to be the same as Sony and Nintendo in making game consoles. Selling hardware at a low price does not make money, and then makes money by sharing software. In this way, of course, they do not make as much money as Apple in history.But it will not give other systems like the old Android in history a living space!Imagine if Apple's mobile phones were sold at a par.How is Android still alive?

Therefore, Jia Hongjian and the others would definitely not sell the mobile phone so expensively, and under such circumstances, even if they sell it at a low price, it is actually because of the configuration.The price of this phone can't come down.It will also keep many consumers out of the door!After all, this is not an era when mobile phones costing 3000 yuan or 1000 yuan are popular in later generations.Jia Hongjian still buys mobile phones costing more than 1000 yuan for his own use all these years ago. If the iPhone hadn't come out, he wouldn't have bought thousands of mobile phones!In such an era. If it costs around 15002000 yuan, it’s a student phone, and if it’s around 2000 to 2500 yuan, it’s the mobile phone used by ordinary adults after work. It may even exceed 4000 yuan, but how can ordinary people buy a mobile phone that costs more than 500 yuan?So such a 50 yuan mobile phone can sell about [-] million units worldwide, which is a good result!In China, it is estimated that selling about [-] units would be great!

As for Jia Hongjian and the others, they don't make money from the selling price of mobile phones!You said that we can earn 4000 by selling 2000, so it is a bit logical to sell it expensively, and we have our own considerations to keep consumers who can’t afford it.But Jia Hongjian wants to get such a mobile phone, in fact, he wants to make money by relying on software.So obviously the more consumers adopt their platform, the better, and the platform blocks consumers from entering, which is a very big bad news!In fact, Jia Hongjian raised the configuration so high, mainly to avoid the limelight from Apple and Motorola, and also to compete with Nokia.To put it bluntly, I just don’t steam the steamed buns to gain popularity, in order to gain the commanding heights of the brand, making people feel that Huaxia Hi-Tech has a mobile phone that is better than foreign famous brands!It is to raise the grade of the entire Huaxia Hi-Tech!But such an approach will still hinder consumers from entering.

So what to do?What else can I do?Let's find a way to enrich the product line, and find a way to get a cheap mobile phone!That's right, get a slightly cheaper version so that ordinary people can afford it!Isn’t the millet of later generations not only Mi 1, but also Redmi and Mi 1s?Although Mi 1s is an enhanced version of Mi 1, it has also enriched the product line, and it has also made Mi 1s, Xiaomi and then Redmi with such a price gradient!Let consumers have choices from 800 yuan to more than 2000 yuan!So can't we learn this?For example, when Jia Hongjian first helped Shanda Enterprise to make electric bicycles, didn't we divide into several grades?Didn't we just design a top-level electric motorcycle as a "treasure of the town store"?You can do that now!

Just like the configuration design in our earliest days, the design at that time was a 3.5-inch 26-color TFT LCD screen. Various configurations were added in a mess, and the cost was actually about 2500 yuan.A mobile phone with such a configuration can run the new Android system, and it can run smoothly.So can we put such a configuration on the market as a "simple configuration" version?Even if we lose money in the early stage, we can sell it at the price of 2500 for the cost of 1999. Can we sell one at a loss of 501?Of course, if we lose a lot in this way, it may be necessary to make it a hunger marketing or something in the form of panic buying.Then wait for half a year when the cost of materials will come down, and we can open it up and sell it. Isn't that good?You have to know that selling a machine at a loss is really not shameful. Like a Sony host like ps3, when it started selling it, it cost about 600 US dollars. As a result, the price is not that much, and it sells an average of one Taiwan was going to lose $260, but didn't Sony still sell it?Isn't it because after the popularity increases, the software can be commissioned?
