Now available in the market, generally, there are two mobile power solutions: Output 5V / 1A and 5V / 2.1A. Of course, the faster the current increases to charge the phone, but not in order to quickly, and all of them with a 5V / 2.1A, we need to consider the suitability of the problem of digital products. Adaptation is important, because you can achieve maximum efficiency, power moves, the reason for setting up the two output interfaces apparently considered this aspect, in terms of more fundamental, this is its mobile power solutions nature of internal internal lithium decision. Lithium battery discharge process understanding of people know that, in the case of the same piece of lithium were large discharge current and low current, the output power will vary, manifests itself in the case of large currents slightly smaller output capacity. When the lithium battery charging equipment is low, we are charging for mobile power, mobile power will be discharged at a greater power output under constant, the output current will be close to being charged to the nominal input current, such as 5V / 1A, and when the cell phone battery is charged gradually increased, the mobile power supply output current will be reduced, the output power is gradually reduced, the output parameters from the previous drop 5V / 1A to 5V / 0.7A. As for the relevant written output configurations of 2A, for example: ipad, camera and so on. Which is more adapted to output 5V / 2.1A, and should keep ipad have appropriate power, if not, then it should be designed as intelligent mobile power, in power small, mobile power solutions in order to be able to automatically identify the start with a smaller current output, the appropriate power device there should generally be 20% of the nominal capacity of the charge amount. For portable power applications for smart phones typically 5V / 1A, and the current smaller devices, for example, when we go out, so long as mobile phones and other devices are idle magic bubble charge treasure, and power is not fully charged in the case, most Good use of mobile power for small current charging status for mobile phones, so that it can reduce power wastage move more electricity at higher current output state. Choose presence batteries batteries quality defects, other accessories designed to re-well, this mobile power quality can not be guaranteed. So mobile power batteries are the most important part, is the first choice. Currently mobile power batteries, there are two, one is 18650 lithium-ion batteries, lithium polymer batteries one is. What is 18650 lithium-ion batteries? 18650 originally refers to the battery form factor, diameter 18mm, height 650mm. Now more than that kind of like the 5th battery lithium-ion batteries. Such high dielectric core storage efficiency, the theoretical number is 1000 times the storage charge treasure fast charge, non-toxic substances, absolutely safe and environmentally friendly. 18650 lithium batteries due to the use of liquid electrolyte rechargeable treasure, when the occurrence of overcharge (overcharging), the internal pressure will surge. In order to avoid an explosion, usually 18650 will be equipped with a safety valve on the top charge treasure that good when batteries excessive internal pressure, the valve will automatically pop up at the top, in order to play the role of decompression. But even if the safety valve pops up, batteries will not explode phenomenon, but the batteries leaked internal lithium ion and oxygen gas as a result of contact, there will still be a fire phenomenon. In order to reduce the risk of fire, 18650 lithium batteries should be in supporting a protection IC to prevent overcharging (over discharge). Charging treasure fast charge, charge treasure, can be provided by the Shenzhen Municipal Shuo Shuo New Energy Co., Ltd. Shenzhen Shuo New Energy Co., Ltd. (www.molipow.com/page-about.html) strong, credible, in Shenzhen, Guangdong phone's battery industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will be able to lead the Master into the brilliant and you work for a better future!
