Power Bank selection? Analysis of three types of batteries

　　Good power bank, the key depends on batteries. Power Bank inside the battery is like a car's fuel tank and transmission system, responsible for the entire mobile power to provide a steady stream of power, directly determines the mobile power good or bad. Mobile power circuit board can be seen as a control system, mainly responsible for the power distribution and conversion, the lithium batteries provide 3.7V (or higher) voltage is converted to standard 5V (or higher) voltage, to To provide power to the device being charged.

　　The current mobile power batteries generally use lithium-ion batteries, but the performance varies, but also from the shape is completely out of sight, the general specifications can not be reflected. The following from the battery to start, step by step to explore the mysterious world of mobile power.

　　First, lithium cobalt oxide (LiCoO2)

　　Lithium cobalt oxide is commonly known as liquid lithium-ion battery, a common form of 18650 and the shape of the box. 18650 battery is a diameter of 18 mm, 65 mm high cylindrical battery (looks like the 5th battery of the enlarged version), widely used in laptop batteries. As with the laptop battery, now on the market more than Liucheng mobile power use is 18650 battery.

　　Lithium-ion batteries are currently commercialized as a cathode material. The theoretical capacity is 274mAh / g, the actual capacity is about 140mAh / g, and the actual capacity has reached 155mAh / g.

　　The cathode material has a high working voltage (average working voltage: 3.7V), and has stable charging and discharging voltage, small volume, high specific energy, good cycle performance, high electrical conductivity, simple production process and easy manufacture.

　　Main advantages: technology is mature, a wide range of applications, small size.

　　The main shortcomings: the life cycle of 300 or so, low security, anti-overcharge poor, not suitable for high-rate charge and discharge, after the pollution of the environment.

　　Second, nickel and cobalt manganese (LiNiCoMnO2)

　　Nickel-cobalt manganese, also known as ternary material (LiNiCoMnO2), is a polymer lithium-ion battery, a common form of soft packet shape. Note that lithium cobalt oxide can also be made into a box shape, but after molding is hard, pinch can be distinguished.

　　Ternary materials with the popularity of smart phones in the past two years the rapid development of the use of more and more areas. It is nickel salt, cobalt salt, manganese salt as raw material, the proportion of nickel-cobalt-manganese can be adjusted according to actual needs.

　　Ternary material to do positive battery lithium cobalt oxide battery relative to the high security, life is higher than lithium cobalt oxide, reached 500 times the use of cycle life.

　　The main advantages: the volume of diversity, the use of a very wide range, not easy to explosion, high safety factor.

　　The main drawback: higher prices, environmental pollution after the waste, high current charge and discharge performance is weak.

　　Third, lithium iron phosphate (LiFePO4)

　　Lithium iron phosphate chemical name ferroelectric, and the front two types of battery the biggest difference is that the battery cathode joined the iron element. Lithium iron in recent years has just started, is a very promising material, its safety performance and cycle life can not be compared to other materials, which is also the most important technical indicators of power battery. Charge and discharge cycle life of 2000 times, a single battery over-voltage 30V does not burn, puncture does not explode.

　　Lithium iron phosphate cathode material made of high-capacity battery easier to use in series to meet the needs of frequent electric vehicle charge and discharge, and has a non-toxic, non-polluting, safe performance, wide range of raw materials, cheap, long life, Is a new generation of lithium-ion battery ideal cathode material.

　　At present, ferroelectric high-capacity electric buses, signal base station energy storage and large-scale UPS applications, including mobile power, AA batteries have just begun to test the water mass production, which makes ferroelectric gradually in the large-capacity UPS, small energy storage battery , Caoping Deng, power tools are widely used.

　　Main advantages: 2000 cycles life, high current charge and discharge, less resistance to heat less, safe, environmentally friendly non-toxic.

　　The main drawback: expensive, digital products have not yet been used in large-scale, low-recognition of the minds of consumers.

Power bank that thing,you know?

　　Popularity of smart phones, the relative stagnation of the popular one-piece design and battery technology, allowing power bank to become the junior partner essential travel home accessories. How different from the color of the shape, battery capacity power bank, choose the most suitable for their own money?

　　1. Large size power bank or mini power bank

　　Power bank inseparable from the "mobile" word, portability is the primary consideration, before buying you need to weigh its volume. Some hundreds of million mAh mobile power volume is often too large, although able to charge the tablet and other devices, but they are not suitable for everyday carry. In general, the phone is fully charged to meet once (probably around 5000mAh), compact style would be a good choice for everyday commuting.

　　2. The capacity is the key

　　Power bank battery capacity is usually expressed in numbers is naturally bigger and more attractive with the "mAh" (mAh). Before OEM power bank, small partners need to know about their own use of the device battery capacity, which is advantageous in terms of the performance of mobile power. Such as mobile phone battery capacity of 1500mAh, a capacity of 5000mAh mobile power charge can be achieved in theory, about 3.3 times.

　　But in fact, the use of power bank lithium battery material itself is self-discharge characteristics, coupled with the loss of discharge, can not achieve the basic theory of charge cycles. For example, the above example mobile power that can charge the phone 2.5 times the performance can be justified.

　　3. The safety-related control chip

　　Since the power bank is actually used to control the discharge of an integrated circuit, the control chip is equally important, be able to identify the charging status of the device, and a corresponding change in the behavior of the charger. Generally speaking, with fast charging, mobile power outstanding safety rating, and other advanced features are used to better control chip, relatively speaking, more secure, the purchase may be appropriate attention.

　　4.battery quality can not be ignored

　　Although power bank  look the same, but the inner clearly different. In addition to the cost of part of the decision mentioned above, the control chip, and the lithium battery itself. In general, well-known international manufacturers of battery performance and have a good reputation.

　　Of course, the price is a critical, expensive is not necessarily the best, but with less low-cost mobile power lithium batteries must not be very good.

Learn to safely use power bank

　　Power bank (Mobile Power Pack, MPP), also known as charge treasure, travel charger. A set of power bank supply and charging functions in one portable charger, you can give mobile phones, tablet computers and other digital equipment charge anytime, anywhere.

　　Different types of power bank core components, briefly speaking has two parts, one is the storage capacity of the media, and second, the other medium energy into electricity. So batteries can be good or bad as an important measure of the quality of power bank.

　　Power bank, the designer from the environmental design, art, portable and many other considerations. The market was further personalized adjustment. Once again, the power supply to the mobile industry to bring a new design concept. The reason is called mobile power mobile power, the main idea is attributed to a portable, lightweight.

　　Split Additive

　　Split a power bank, energy absorption by a plurality of blocks with a combination of novel not only it looks chic, and very playful, full of fun. Fuselage equipped with LCD display, can accurately display the remaining battery condition. Each power block has a nominal capacity 2600mAh, it can be added together, the total expansion of overall capacity to meet the electricity demand of different user needs.

　　Stylish compact

　　Mobile power appears, at this stage no doubt eased the intelligent end-use of electricity shortage problem, easy to carry mobile power, mobile features brought us great convenience. Mobile power now belongs to carry goods, to ensure product capacity on the basis of how to reduce the volume of the product, make the product more compact, easy to carry mobile power appearance is one of technological innovation trends! Secondly, how advanced industrial design, and even humanistic idea in the design of the mobile power, mobile power to make feel more comfortable, more fashionable, but also mobile power technology innovation trend.

　　Built-in rechargeable line

　　Built-in charging cable mobile power. For mobile power users, in addition to the charge for the digital products, the mobile power user but also the pursuit of portability. So the built-in rechargeable mobile power line came into being, with the built-in charging cable, users can no longer find charging cable and adapter to worry about. Only set yet made a built-in three mobile power appearance of patent and utility model patent certificate. This built-in three mobile power products built Apple charging cable, MICRO and MINI charging cable charging cable is compatible with most of the mobile phone market.

　　LED lamp type

　　Mobile power with LED lighting and with the charging function, this mobile power is currently the most popular on the market. The advantage of this type of mobile power capacity, but also with a convenient LED lighting in low light situations, very suitable for professional external power supplies.

　　With solar type

　　This type of mobile power can be used in areas of relatively long duration of sunshine, but the general applicability is not strong. Mobile power with solar panels, during use can be charged by solar power so as to make up for the purpose. Such mobile power before the main application in the special forces and special industries. With the gradual improvement on the civilian conversion rate of solar panels, gradually popular.

　　Tablet type

Power bank shell material, how to choose?

　　Large capacity smart phones, tablet computers and other digital products in our daily lives more and more popular, which directly led to the portable charger power bank development. Many readers now have become accustomed to in their own carry bag and a power bank that can charge digital devices at any time, its compact lightweight nature provides us with a great convenience.

　　1. manufacturers currently on the market of power bank shell material

　　Mobile power supply is our most contact with the shell, which is also when we buy products for the entire power bank first impression. Housing can also batteries and circuit boards play a protective role, they appear to prevent damage in daily use.

　　Currently housing mobile power on the market is basically divided into two categories: metal and plastic materials. Due to cost and convenience needs, most of the current mobile power market have adopted the lightweight, inexpensive, beautiful and easy processing of the plastic housing, while most of ABS or ABS / PC plastic material, having impact resistance, heat resistance, low temperature resistance, surface gloss and good features, and easy to paint coloring can also surface plating and electroplating operations.

　　2. The flame retardant housing status of power bank on the market

　　???????However, when we search the Internet mobile power plastic shell found, uneven product quality, price from fifty-six cents to have seven or eight dollars, the most important difference is that the flame retardant material. Power bank shell has good flame retardant properties, even if the mobile power inside for prolonged housing also less prone to cause spontaneous combustion due to circumstances beyond batteries self-extinguishing after ignition of the housing.

　

　　3. Power bank supply housing that selection retardant materials

　　???????PC / ABS Despite its good impact resistance, heat resistance and surface gloss are widely used in mobile power shell, but still there is a huge security risk, PC / ABS PC in the main chain containing benzene ring, can be reduced when the combustion synthesis of aromatic carbon, can be self-extinguishing, but dropped the burning of the melt combustion; and will produce thick smoke and choking odor ABS combustion, which is why ordinary mobile power shell ignited after produces thick black smoke and accompanied by reasons for the burning of the drip, drip of these burning combustion will lead to the surrounding clothing, flooring, purses and other items, causing a larger fire, and thick black smoke and smell will directly lead to people choked to death, and therefore a great security risk.

　　Although retardant class PC / ABS has been developed, but due to higher costs, lower levels of flame-retardant, the application still has some shortcomings, it is difficult to be widely applied to a mobile power supply housing. More importantly, being drafted in the GB mobile power will inevitably move its fire-retardant properties of the housing has a strict standard, once introduced, flame retardant non-compliance of PC / ABS, ABS will be eliminated by the market, the next generation power shell material is what really worth mobile power shell modified plastics manufacturers and suppliers of common concern.

　　4. Does retardant PP Housing material for next-generation power bank of choice?

　　Retardant PP has excellent flame retardant properties, the price has more advantages and more environmentally friendly features, has been in hiding in application areas such as socket, wall switch, home, etc. only successful alternative flame-retardant ABS products.

　　Compared to other flame retardant products, fire-retardant PP has a higher glow wire (GWFI) and resistance to tracking index (CTI), can be more effective protection against fire or electrical leakage, even if it does not produce combustion of the fuel drops or thick smoke, can really achieve effective protection, electrical safety effect. In addition, the product has a good fire-retardant PP coloring, enhance the overall quality of the product appearance, to a certain extent, it can replace the spraying process.

USB Stick is inserted computer does not respond workaround

　　Use USB Sticks, we will encounter some problems, such as: usb stick inserted into the computer without any reaction. Here are some of u disk insertion computer does not respond to reason and common problem-solving methods.

　　Cause usb stick inserted into the computer does not respond:

　　1, the front USB cable connected correctly. When the front USB interface corresponding to USB cable motherboard and chassis contact, positive and negative reversed if such failure occurs, and this situation is likely to make the USB device burned, so try to use the USB chassis rear interface or extension cord should be used sparingly. Fracture may also be a problem, you can try another USB port.

　　2, USB interface voltage insufficient. The removable hard drive connected to the front USB port, it is possible to produce the system can not identify the equipment failure. The reason is that mobile hard drive power is relatively large, the voltage requirement is more stringent, the front interface may not provide sufficient voltage and poor power supply also contributed to the cause of the problem. The solution is not to take mobile hard disk on the front USB port, if the conditions, you can replace the power supply for low - or use an external power supply of the hard disk cartridge.

　　3, motherboard and system compatibility issues. Such failures are the most famous NF2 motherboard compatibility issues with the USB. If you encounter this problem in the NF2 motherboard, you can install the latest drivers and patches nForce2 dedicated USB 2.0, the latest motherboard patches and operating system patches, if that does not work, you can try to refresh the motherboard BIOS.

　　4, when the reader must not pull out the usb stick, it is possible to burn the chip. XP taskbar icons in the USB device, you should choose to disable the device, and then unplug the device.

　　USB Stick factory insertion computer did not respond Solution

　　If the system is WinXP, motherboard supports USB2.0, plug in the USB flash memory interface, nothing happens, but in the open "My Computer" icon does not flash, you must restart the computer to recognize the USB flash drive and reinstall the system program useless.

　　If USB2.0 interface drivers are not installed correctly on the motherboard, under normal circumstances can be USB1.1 ports are operating system automatically recognizes and drives, but USB 2.0 standard USB controllers and drives are not recognized by the system. If the system is WinXP SP1 version does not have this problem, and if not, the operating system can not properly identify, you need to install a special driver can be identified. According to the motherboard model you need to install the corresponding USB 2.0 drivers that allow USB2.0 port to work.
