Need to know the internal structure of the key components of the material is produced domestically or imported, such as capacitors and boost system; we can ask the seller or to search for a particular brand of charging what gem material. How to say in this area, there is still no charge treasure brand, but also because of its shorter enter the market, so the reference to the sales charge treasure some more tricky, because of the large manufacturers sales charge treasure bubble magic words, production, and quality The agency will have a special quality testing and control. 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 storage times for 1000, does not contain toxic substances, absolutely safe and environmentally friendly. 18650 lithium batteries due to the use of a liquid electrolyte, when a overcharge (overcharging) case charging treasure ranking, its internal pressure will surge. In order to avoid an explosion that good charge treasure, usually 18650 will be equipped with a safety valve at the top, when the batteries internal pressure, the safety valve will automatically pop up at the top in order to play the role of decompression occurs. 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 USB charging, large energy (certified), charging treasure provided by Shenzhen Shuo New Energy Limited. Shenzhen Shuo New Energy Co., Ltd. (www.molipow.com/page-about.html) Guangdong Shenzhen, a leader in mobile phone battery, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum meet customer needs. In the master to lead the staff warmly welcome all inquiries negotiations to create a better future can master.
