The main role of the PCB board

The ideal power bank for mobile consumer power is nothing more than the large capacity, fashion and safety. Cell is the battery, but the use of different batteries, such as 18650 lithium batteries and lithium polymer batteries will have the direct impact on the quality of portable external battery charger. The main role of the board is to upgrade battery voltage in order to match the charging voltage of electronic devices, such as mobile phones and iPad. In addition, good quality mobile power supply circuit board also should have short circuit protection, overload protection and safety protection circuit. While these "internal" materials often are ignored by consumers, causing only nominal capacity of mobile power is taken as the sole criterion to measure their advantages and disadvantages.

PCB board-the key to judge the quality of external battery

There are hundreds of mobile power in the market, and we are unable to distinguish their advantages and disadvantages just from the appearance, such as there is a huge difference for the lithium batteries of different brands in the quality of mobile power, while the quality of the PCB board is even more important, because the board is responsible for the mobile power conversion efficiency, various protection mechanisms, and the output effect, means that the design of the circuit board work directly determines the output quality of mobile power.

Therefore, if the PCB board of the Iphone External Battery can be reasonable workmanship and design, and take the use of the solid protection circuit quality lithium polymer batteries, then this mobile power has quality assurance.

Protection and design of power bank board

Design of power bank board and quality decided the quality of output of mobile power. While some brands of mobile power supply usually directly use the public version of the design, in order to save development costs, and they directly launch the mobile power by adding case. This product has no personality, and in addition, it is subject to the male mold design and cannot meet its own product characteristics to be optimized. The brands who pursuit of individuality and quality are committed to self-development board and mold, and give consumers a better mobile movie products.

Wholesale power bank

With the current popularity of digital products and fast - growing and developing, the definition of wholesale power bank is convenient to carry the bulk of personal power. The digital products features increasingly diverse, used more often, and increasingly close associate of our daily lives, so it is even more urgent how to improve the use of digital products, maximize importance of the functions. Mobile Power, are designed to be the best way to resolve this issue, carrying a mobile power, it can be done in outdoor anytime, anywhere mobile power for a variety of digital products

Works

Mobile power is a set of electrical storage, boost, charge management in one portable device. Electricity storage media commonly used lithium batteries, because of the relatively small size of lithium batteries, large capacity, wide market liquidity, affordable, widely used in digital products. Lithium voltage 2.7-4.2V between the voltage decreased with the decline of the power. 2.7-4.2V of voltage can not be directly charged to other digital products, digital products lithium battery voltage is 2.7-4.2V, the voltage between the same potential can not charge. Mobile power external output power must be step-up system, the lithium battery voltage of 2.7-4.2V of the step-up to 5V, so that you can charge to other digital products, such as mobile phones, mp4, Tablet PC, PSP, etc.. Of course, the mobile power is not one-time equipment; it can be repeated by hundreds of times. So when the mobile power after the power usage, we must give mobile power charging. The principle and charge their cell phones. Connected to 5V USB computer interface or USB charger can charge for mobile power. Mobile power must also be within the charge management system. Charging management system based on the voltage of the lithium, automatically adjust the charging current. Process: pre-charge, constant voltage charging and floating charge.

Classification of mobile power batteries

Mobile Power Cell types are only two, one for general Li - ion cores, another for Polymer batteries. Both in the material composition and appearance there’s a big difference.

General battery - cell battery

General advantages of lithium cell battery are: Because of the long development time, the battery very low price. Disadvantages : more revision of waste batteries, for technological reasons, issue rate and high failure rates.System, and the weight of heavy, short service life and is likely to cause an explosion, this is a fatal flaw, the current mainstream mobile power phase-out of the batteries. In the years to come, the general Li - ion cores will gradually withdraw from the stage of history.

Polymer battery

The lithium-ion battery electrolyte material, lithium ion batteries can be divided into liquid lithium-ion battery, referred to as LIB) and polymer lithium-ion battery (polymer lithium ion battery, referred to as LIP) two categories. Polymer lithium ion battery anode materials for with liquid lithium ions are the same, cathode material can be divided into lithium cobalt oxide, lithium manganese oxide, ternary materials and lithium iron phosphate material, negative extremely graphite, battery works are basically the same. The main difference lies in the type of electrolyte, liquid lithium-ion batteries use a liquid electrolyte, polymer lithium-ion battery with a solid polymer electrolyte instead of this polymer may be a "dry state", it can be "colloidal, polymer gel electrolyte.

Batteries grading system

According to the national standards of the battery, especially for polymer battery has a strict classification system. According to the quality and timeliness of the battery is divided into three levels - A electrical power B and C power. A power - the new polymer battery, electric B - inventory of more than three months or disassemble battery, electric C - used batteries. Of particular note is C power is cheap, but there are serious quality problems, B electricity prices first low, but the recession is very fast. A power mobile power in the economic circumstances permit, please purchase.

Steps:

1: select mobile power setting you want to connect the 3C products: such as mobile phones Tablet PC, notebook, laptop battery and so on.

2: 3C products to be connected: Determine the required output voltage, current, capacity (power).

3: According to connect to 3C products:

Decided to single-function for the (single output) or multi-function use (dual output).

4: Determine the required additional features. Decide the shape of the mobile power: light, thin, short, small

A more usual mobile phone, recently wanted to buy a mobile power, heard about mobile power will likely burn, ever master can I explain it?

B personal feeling, mobile power to put it plainly, is a small battery. Battery is at risk of burning

C used to have a lot of people say, batteries, rechargeable batteries can burn, see how many people are now friends say? I is in Patriot do research of, told everyone, water are has may is choked died, mobile power burning of possibilities certainly is some, but very small, let you met of possibilities more is little, all large enterprise large brand, products materials elegant, and factory Qian after strictly test, buy these brand of mobile power, burning of possibilities than you in the 5 million of possibilities also small have more.

Dell laptop batteries have happened before b Burns, global recall, Dell battery is Panasonic's OEM, not to mention other brands do, Patriot cow than a Dell and Panasonic?

D is therefore WOPOW LMT mobile power solution not only from products, punches or services and third party insurance to avoid any possible mistakes.

LMT mobile power system products using imported from Samsung cell, each product in the harsh environment before they undergo a rigorous test, was sampling the test is not well, and shell all is fire-resistant PC material. Let alone will not burn, burning is just in case I will fear no evil, WOPOW PICC insurance are also worth millions, if burning, I will fear no evil, PICC huge compensation.
