1. First choose a genuine, quality after-sale protection; 2, choose a more than four battery indicator lights, which are with the software management, multi-layer of protection inside customized mobile power, more secure. 3, do not choose the high price of genuine mobile power of the same capacity, production costs are basically the same, just a different brand positioning, resulting in a large retail price difference; 4, do not fly too cheap, a lot of fake and shoddy products on the network, are virtual standard capacity mobile power, looks very cheap, actually, not only did not guarantee the quality, capacity, and some less than half; 5, will ask a few questions:. a This power can do for my phone XX mAh battery charge a few times? b. How long the charge of its own? c. It gives me the IPAD charge how long? These three issues are there in order to estimate the capacity of vacuity, there is no input current vacuity mobile power quality, the output current has no vacuity. Also, do not need to open you can verify; 6, not too much capacity, with a good evening to charge the mobile power Guangdong, this will not affect the next day carry. Really need large capacity, might as well buy two, more convenient; 7, if there is a clear way to choose ternary cathode material for steel batteries, such as the 18650 model, which also steel batteries and soft bag polymer is as safe, and the failure rate is also lower. Because polymer batteries are susceptible to soft bag extrusion affect performance; 8, lithium cobalt oxide cathode materials for steel batteries not the best, the worst kind of safety performance, before the explosion is this. (Now one of the five batteries giant country, especially Samsung and Sanyo, have all been done without lithium cobalt oxide cathode, full use of the ternary material) mentioned wireless charging, will certainly be a lot of people think of the radiation problem. In fact, wireless charging treasure belongs to the work of ultra-low frequency electronic devices, according to the Wireless Power Consortium's specification documents show that the current wireless fruit filled treasure 50-60HZ operating frequency is set at this range, the electromagnetic radiation levels and general quite small appliances, and this less than a standard product for public access EMF exposure limits International Commission on Non-Ionizing Radiation Protection issued, it is safe to use. Mobile power supply manufacturers, mobile power, can be provided by the Shenzhen Municipal Shuo Shuo New Energy Co., Ltd. Shenzhen Shuo New Energy Co., Ltd.
