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
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.
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.
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
