In fact, the price of mobile power is to look at the brand, quality and capacity as well as sale of different brands, quality, capacity and sale prices are different. Mobile power prices generally ranging from tens to hundreds have, generally available in the price range between one to three hundred, do not choose too easily hurt cheap cell phone batteries, and the performance is indeed much worse. On the other hand, it also depends on what kind of price you can accept, and now the price difference between the power of a big move, but it is best to buy quality guaranteed, and the price is also affordable, many big brands are also some prices slightly Low mobile power, might capacity is not great, but at least the quality of clearance, it is also at ease with. 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 protection, safer. 3, do not choose the high price of genuine mobile power of the same capacity, production costs are basically similar mobile power, just a different brand positioning, resulting in a large retail price difference; 4, do not fly too cheap, and now the network of fake and shoddy products Many are virtual standard capacity, looks very cheap mobile power quality, practical, not only did not guarantee quality, capacity, and some less than half; 5, will ask a few questions: a power source for me this XX mA. mobile phone battery charging 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 virtual standard input current, output current, there is no vacuity. Also, do not need to open you can verify; 6, not too much capacity, with a night full charge as well, 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 models of mobile power magic bubble, the steel batteries also and polymer soft pack 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) Guangdong mobile power | mobile power | Shuo Shuo provide by Shenzhen New Energy Co., Ltd.
