Hello everyone, I am a good student. This year's Encyclopedia of Aunt Zhang, let's talk about mobile power, what's around here.
indexFirst, tracing the source of mobile power
Second, the use of mobile power
Third, mobile power cell types
Fourth, the brand's fast charge agreement
Fifth, the choice of Android users
Sixth, the choice of iPhone
Seven, purchase considerations
Text I. Traceability of Mobile Power SourcesThe earliest mobile power sources can be traced back to the 2001 CES show. At that time, it was an overseas student who had assembled a few AA batteries and a control circuit. This should be the earliest prototype of mobile power.
Although there were manufacturers who fancy this solution at the time, due to the immature cell technology and power management solutions at that time, the cell was too large and the cycle life could not be guaranteed, so it was not widely used.
However, this form of product that can be used to charge the device can be formed at any time. Over time, the industry chain related to mobile power is also rapidly developing. From the power control to the battery application, etc., there are a series of suppliers to gradually make the product form.
â–¼ On the development node of mobile power, iPhone's hot selling is worth mentioning
â–¼ Before the popularity of the iPhone4, the vast majority of mobile phones can be disassembled battery design
â–¼ Including Nokia, Samsung, Motorola and other giants are all able to change the block of cells in full blood resurrection. I remember when I bought my cell phone, the first thing I did was buy a spare battery. This usage habit is not enough to quickly promote the use of mobile power.
The design of the iPhone's non-removable battery was also very miserable at the time. However, the user’s habits are still educated by Apple’s lead market. In recent years, mobile phones have gradually become non-detachable battery designs. Currently, there are only a few models that can find exchangeable batteries in the market.
â–¼ Even a removable rear cover such as a nut is not replaceable
For the time being, regardless of the pros and cons of non-removable batteries, the most immediate impact on users is that they cannot resurrect themselves with a battery change, and instead need to seek additional power supply. In addition, there is no breakthrough in battery technology. The current battery life of smart phones is still a problem many people face.
This node, the era of mobile power has finally come. In recent years, the mobile power market has also seen explosive growth, with a wide variety and rapid updates.
As a portable charging solution, mobile power can always supply power to electronic devices. Maybe some friends will ask, now many mobile phone charging stations in the hotel's airport do not need mobile power.
â–¼ Charging in this fixed position cannot be “anytime, anywhereâ€
In some non-standard charging piles, criminals steal information on mobile phones through special means. I have encountered it once before, connected to charge, the iPhone jumped out to trust the computer's prompts, replaced the Android machine, not surprisingly open the USB debugging. Be aware that once these two modes are turned on, the background operator can obtain personal information from your mobile phone. Normal charging does not require the use of these two modes.
CCTV also reported such incidents. We must pay attention to this situation.
In addition, there are various fast charging protocols for Android machines. Most charging stations cannot and will not be compatible with all fast charging protocols. Basically only 5V/2A charging, which is greatly reduced in terms of efficiency. For self-built charging stations such as the OPPO, the delivery speed and the number of bases are also a big problem (in the original Weibo, intrusion).
Some friends are accustomed to using the socket on the high-speed rail to charge, but often encounter the problem of screen drift. This is because the power supply of the high-speed rail is connected to the contact network. When the phase is exceeded, the voltage and current will fluctuate and the pressure on the charger will be greater.
In summary, mobile power has its own advantages in many scenarios. Being away from home, convenient portable and stable output, but also has its own irreplaceable.
Third, mobile power batteriesThe common mobile power cells on the market are 18650 and polymer.
(1) 18650The 18650 is the originator of lithium-ion batteries and is a standard lithium-ion battery model that SONY set for the sake of cost savings. 18 denotes a diameter of 10 mm, 65 denotes a length of 65 mm, and 0 denotes a cylindrical battery.
The 18650 is the earliest, most mature, and most stable lithium-ion battery with the advantages of stable technology, low price, and good safety, and is suitable for large-scale use. The most obvious drawback is that the volume is slightly larger and the shape is not variable. Therefore, the mobile power supply using this battery core has a design of N*18650.
It refers to the use of aluminum plastic packaging film as a lithium-ion battery packaging, which is what we often say soft pack battery. The advantage is simply that it is thinner and the form can be changed. It can be customized according to the needs of customer service. Decentralization to the product can have more appearance changes. However, the cost is relatively high compared to 18650, and the product price will be higher.
The specific technology will not start. Let's talk about the security issues of both. It seems that from the beginning of last year, there has been public opinion on the market that "only polymers are king." These remarks all emphasize that polymers are safer than 18650. This point of view, I do not think it can be generalized.
First of all, we do not think 18650 is not safe. 18650 is just a specification of the name, there are many manufacturers, large Panasonic / LG and other large factories, small to small workshops can also be done. The material, composition, energy density, and battery capacity of the batteries are also different. We are familiar with the Tesla Model S, which consists of more than 7,000 Panasonic 18650 batteries.
In recent years, the domestic market environment has driven a large number of low-quality 18650 into the market driven by interest. Many profiteers have used the foreign garbage dismantling and electromechanical core as new sales, causing everyone to question the safety of 18650. The regular factory 18650 will not explode in normal use. Polymer batteries, if used improperly, such as impact, puncture, etc., can also cause explosions.
Of course, I'm not saying that the polymer is not good, and the polymer cell is small, portable, and has a variable shape that represents the direction of future mobile power. Just hope that when you buy, unless light and thin, do not have to pursue polymers, using the products of the Dachang 18650 battery is also a good choice.
Fourth, the brand's fast charge agreementMobile power and chargers are all products that need to be adapted to their own mobile fast charging protocols. At present, the Android camp, the fast-charging agreements of various brands, cannot be overemphasized. The traditional Micro usb interface has a maximum current carrying capacity of 2 A. Fast charge is technically only two ways out. Increase the charging voltage or change the physical interface to increase the current. Therefore, fast charge in the market is generally divided into high voltage and low current and low voltage and high current.
QC fast charge is a typical representative of the high-pressure camp, and it is also the protocol with the highest market occupancy rate. It has evolved from 1.0 to 3.0.
Representative models: Xiaomi 5, Samsung S7edge (QC2.0), Jinli M2017, Nubian Z11, ZUK Z2 Pro
The fast charge protocol also achieves fast charge by increasing the charging voltage, supports voltages of 5V, 9V, and 12V, and PE2.0 supports 5V-20V, 500mV gears. Meizu's fast charging protocol is also based on PE development
Huawei's Hass Fast Charge is also using a high-voltage solution, also known as Huawei's FCP fast charge. Supports 5V/2A and 9V/2A, suitable models such as Huawei P9, Mate8, Glory 8, Glory V8, Glory Note 8.
Before changing the design, 4.5V/5A, 25W, joined the low pressure fast charge ranks. Supports the newly released Mate9 and P10 series.
"Charging for five minutes and talking for two hours." This is an early OPPO fast charging campaign and a familiar case of classic marketing. Also typical of low voltage and high current, the maximum current carrying capacity of Micro USB interface is 2A. OPPO has added two pins at the port to achieve 5V/4A specification through higher current. The extra 2 pins will also be used for identification. The charger and data cable connected to the home will turn on the fast charge.
It also moved the buck line to the charger, without having to go through the internal conversion of the mobile phone, and the charger is directly charged to the battery, which is simple and crude. It must be said that this scheme is very smart. In the early stages of other fast charging, it also brought good benefits and reputation to OPPO. The same brand VIVO and one plus (DASH flash) are the same technology, changed the waistcoat. So the meaning of VOCOC may be Vivo Oppo Oneplus Charge, and it seems that there is no problem.
Do you think it is messy, but this is indeed a messy portrayal of Android fast charge. Both chip makers and handset manufacturers have their own charging protocols. Each fast charge is also not interoperable, so mobile power and chargers need to be individually selected. Although the PD agreement may have the potential for unification in the future, it is a long process and we will not elaborate on it today.
In the foreseeable year of 2017, most domestic flagships will enter the era of low pressure direct charging. OPPO VOOC/Huawei SCP/Qualcomm QC 4/MTK PE 3.0. In order to meet the safety requirements for data lines with high currents above 3A, various companies may seal off other data lines. Fast charge is not allowed without the original line, even if the current carrying capacity can reach 5A, it will be sealed off in one go. In the future, it is not only necessary to face the charger that cannot be used universally, and even the data line must be bought separately. It is really disgusting to get home.
Fifth, the choice of Android usersWe start with domestic brands.
(1) Huawei mobile power selectionLike other domestic manufacturers, with their own fast charging technology, they can only choose their own home accessories, including mobile power and chargers, and even data lines.
â–¼ Huawei Mall has 5 products for sale:
Two of them support fast charging, and the other two are just ordinary 5V/2A outputs. The price is expensive and not recommended.
â–¼ Glory 10000 mAh Fast Charge Mobile Power:
Huawei (HUAWEI) glory mobile power supply 10000mAh charging Po fast fast double charge 18W power TypeC and Micro USB dual input fast charge version AP08Q (white) 169 yuan Jingdong direct link This is also the first mobile power supply to support Huawei's FCP fast charging protocol, with an output specification of 9V/2A 18W. Supports C port and Micro usb output.
â–¼ Huawei's 10000 mAh fast charging mobile power:
Huawei (HUAWEI) Huawei 10000mAh mobile power supply / charging treasure fast charge version 179 yuan Jingdong direct link Like Glory Power, it supports Huawei's FCP fast charge protocol, 9V/2A, 18W. Input changed to Type-C, single port output
â–¼ Huawei 20000 mAh Fast Charge Mobile Power:
[New Release] Huawei/Huawei 20000mAh Mobile Power Charging Po Security 299 yuan Lynx Select Direct Link Still only support FCP protocol, Type-C input, dual output. One port supports 9V/2A, 5V/2A intelligent recognition, and the maximum output of 2 ports only supports 5V/2A.
â–¼ Third-party power supplies, as far as I know, only one of Best's power supplies supports Huawei FCP:
Bose 20000 Millimeters Flash Charging Bao Qualcomm QC3.02.0MTK Bidirectional Fast Charge Universal Mobile Power 119 yuan Lynx Select Direct Link Both input and output support Huawei's 9V/2A fast charging protocol
It is noteworthy that the above few, the maximum output is only 9V/2A 18W, not this year's Huawei Super fast charging 4.5V/5A, 25W specifications. Because the current output ICs of mobile power supply are not able to reach 4A or more, the current specification of this specification may not have a mobile power source that can be adapted.
As a representative of MTK PE fast charge, Meizu has made one for itself because there is no mass production of mobile power that supports PE.
â–¼ Meizu mobile power fast charge version
Meizu (MEIZU) fast charging version mobile power / charging treasure 10000mAh compact lightweight and durable 134 yuan Jingdong direct link Support mCharge (MTK PE) bi-directional fast charge, while compatible with QC2.0 protocol. This price is worth recommending, of course, you have no better choice. I also have value for money drying list:
Is 149 yuan worth the money? MEIZU Meizu fast charge mobile power use feel good for everyone ~ long time no see I came to everyone today to disgrace, this brings us the "Meizu M10 mobile power" experience. I believe we have some impressions on the fast charging mobile power mentioned in the Meizu MX5 conference. Some time ago Meizu also successfully raised more than 60 million project funds in Jingdong, and then gradually began to ship to users. Received mobile power for two days and planned to chat with you about Gourd after using it. | Likes 155 Comments 186 Favorites 56 View Details â–¼ The power of the third party should only have Best Support
Bose 20000 Millimeters Flash Charging Bao Qualcomm QC3.02.0MTK Bidirectional Fast Charge Universal Mobile Power 119 yuan Lynx Select Direct Link â–¼ Output Supports MTK 9V/2A Fast Charge Protocol
â–¼ But input is not enough, only Huawei and QC2.0 fast charge input is supported
As a blue-green brand, accessories can only choose their own products. Before OPPO launched a flash charge mobile power, maximum output 3.5A. However, it has been removed last year, so currently there is no perfect support for mobile power in the flash camp.
â–¼ There have been rumors before that VOOC has been cracked by domestic teams and the first product will be mobile power. But after a long time, no follow-up news was released.
â–¼ One plus it also has its own mobile power, called one plus call
OnePlus One Plus One Call 10000mAh Mobile Power / Charging Po (Sandstone Black) 119 yuan feel good, there is a sense of design of mobile power. Jingdong direct link to encyclopedia However, the input and output are only 5V/2A, which is just an ordinary charging specification.
One plus 10000mAh polymer mobile power, my home's first polymer mobile power! Seeing that the New Year is coming soon, the longest way to play a mobile phone on the way home is the only entertainment for many people. I also need a mobile power supply to maintain our needs for hours or even more than a dozen hours! Before that, I also bought several millet, electric two, and Le Soaked three brands, and later they were borrowed and used to never come back! Helpless still have to buy one. Maybe many people like to buy millet. Why didn't I buy millet this time? 1. I want to buy a polymer to play taozhedong| Likes 89 Comments 65 Favorites 81 View Details The current situation, this series of mobile phones, mobile power can only be charged through the 5V/2A mode. As mentioned above, the current mobile power ICs have not yet been able to carry more than 4A of current, so in the future there will be no support for the flash power mobile power supply market, but also the further development of the industrial chain.
Note: Some models in vivo use Qualcomm QC fast charge.
(4) Qualcomm QC user's choiceCompared to some of the relatively niche charging protocols above, QC is currently the most widely used and most user-friendly charging protocol. Chip-level fast charging protocol, coupled with Qualcomm's market share, there are many mobile power options available on the market. We talk about it through different usage scenarios:
â–¼ mini capacity:
Usually QC3.0 mobile power will not have a very small size. Aukey's lipstick power supply should be the only one cell phone on the market that supports QC3.0 mobile power.
Single 26650 batteries, capacity of 5000mAh, support QC3.0 charging protocol, weighs only 143g.
The compact size is convenient for everyday carrying. 5000 mAh capacity is also sufficient for lightweight applications.
Aukey QC3.0 5000_Taobao search Taobao search is the most intelligent commodity search engine, through the operation of big data, accurate understanding of goods and users, to provide accurate personalized search experience. Direct links to s.taobao.com 1000 mAh:
Most mobile power is in this capacity range. At 1W mAh, it is neither as durable as 5000 mAh nor as large and heavy at 2W mAh as a balanced compromise. Because there are so many choices, they will not be listed one by one, but only a few interesting ones. Pay attention to the shell material when purchasing, the current supply chain, the metal shell is not much more expensive than the plastic shell, but the feel and texture will be more poor.
â–¼ Millet Power Bank 2

â–¼ input up to 18W, output up to 15W
â–¼ Use the QC3.0 charger to charge it, the power is 8.75V/2A, nearly 18W. Although there is no Qualcomm QC logo, it means there is no Qualcomm certification, but it does support fast QC charging.
â–¼ If you do not like Millet Power 2 Micro USB input, ZMI this is optional. Micro USB and Type-C dual input, the shell has changed, the other is basically the same.
ZMI 10000 mA Bi-directional fast charge / mobile power / charging Po polymer batteries purple rice support Type-c and Micro USB dual input QB810 white 99 yuan Jingdong direct link Anker QC2.0 mobile power:

Apple's mobile power, choose a lot, after all, only 5V/2A charging specifications. Some friends may ask the iPhone not all 1A charging, in fact, the following models are to support 2A charging.
When using 2A and above mobile power for charging, the above models will recognize charging at 10W.
â–¼ The charging speed will also be greatly reduced, with a time comparison
Still from the use of scene classification, capacity from small to large
(1) Mini PortableBecause the iPhone does not have a fast charging protocol, this type of power supply will be selected more. Less than 100g of weight, to meet the need for 1-2 times the charging, daily carrying is very convenient.

Metal shell, slightly sculpted
On the whole, this kind of single-cell mini power supply still has a certain demand for daily use, and is suitable for supplementing mid-lightweight one day. Especially girls, they should be more like these small products. All three products are 3350mAh, output 1-2A, deal with the iPhone is also no problem.
Like the fast charging just mentioned, 1W mAh is also a compromise between low-capacity and large-capacity, portable and battery-powered. The mobile power on the market can basically be selected, even if it is fast-charged, the iPhone will automatically limit the current to the appropriate current, this do not have to worry about. Focus on the needs of iPhone users for fast charging sources.
When the capacity is up to 1W milliamperes, if you only buy an ordinary 2A input mobile power source, the time for charging the mobile power source becomes very long. At this time, we can consider buying a two-way fast-charged mobile power supply. It only needs to output the input quickly, and the output terminal will automatically recognize the iPhone to give the appropriate current.
â–¼ QC3.0 mobile power access iPhone7, power 5.08V/1.97A 10W
â–¼ Quick charge protocol to choose QC as much as possible, more optional charger. Access QC3.0 charging, 7.08V/2.17A 15.4W output, faster than the average 2A charging
In terms of brand, Xiaomi 2nd generation, Anker, Meizu and others mentioned above are all options. QC2.0 is also a good choice if you use only iPhone. QC3.0 can be understood as an improved version of QC2.0, adding smart regulation and current stepping. Filling time is not much different. 2.0 is usually cheaper than 3.0.
The large capacity of 2W milliamperes can be selected many times, so I will not go into details here.
When buying, pay attention to whether it is a dual-port output.
â–¼ At the same time pay attention to avoid the following figure, you need to manually select the charging specifications of the power
Leaving aside the technical aspects, single user experience is not very good. When using, you need to understand the charging specifications of your mobile phone, and then manually select the interface, the use of a slightly higher cost, can not be used immediately.
â–¼ Try to select dual-port power supplies that support automatic identification. There are many on the market.
It is a combination of mobile power + charger. This product is a good solution to this problem, go out with a device on it. There are two models on the market, the super-charged tycoon and Anker. Both products do not support fast charging, so the most suitable group is iPhone users.
