The consequences if used batteries are mobile power charging effect, short power life, poor stability, mobile power internal circuit is closely related to the stability and safety of the product. Any electronic products have a certain failure rate, if not enough manufacturers are not measures of protection configuration, does not prevent overcharge, overheating, overload and short circuit protection, ranging from easy to make batteries quickly scrapped, appears the products of combustion or explosion accidents.
Is a power supply or a bomb?
Lithium ion rechargeable battery's composition is as follows: battery + protection circuit board. This little battery protection circuit board is fundamental to guarantee user safety, although in theory, mobile power supply problems of the low probability of lottery prize, but there have been several cases. Many profiteers to cost savings through to the end, not just in the products on the circuit board to cut corners, moving some of the ridiculously low price of power there is even no circuit board, much less designed for mobile power supply battery of escort protection circuit board.
Battery protection board function there are two: 1. protect the batteries to prevent battery over charge, over discharge, excessive heat, extend the life of batteries, extending battery performance cycle; 2. minimizes PCB short-circuit, overload failure, the impact on the battery, lower batteries minimize the possibility of Burns, explosions. High quality mobile power products, in addition to the standard distribution core protection circuit boards, also on the choice of batteries, there are higher requirements--requirements of electrolyte in the batteries must be able to prevent explosion pressure relief valve.
Safety of the different types of batteries is also different. Polymer batteries has a flexible surface material, if short circuit cause battery bulges will crack and explode, so safe and 18650 batteries as used steel packaging, the most serious cases of explosion, and lots of mobile power currently on the market in order to reduce the cost of spell cheap, poor quality 18650 batteries,
If you buy the mobile power, even the battery protection circuit boards are not, it is a mobile power? Clearly is a ticking time bomb does not know when it will explode. If faulty, just like a time bomb around, why when we buy products of AMS products brand and price, not blindly pursue the cheapest.
Full range of circuit protection measures while the cost is not high, combined with cost no more than 5 Yuan, but see, for SMEs, a mobile power province 5 Yuan, 100,000 could save 500,000 yuan, is not a small profit. Layers of reduced security, and even a few cents of investment, unscrupulous manufacturers will not hesitate to save, of course, is also the personal safety of consumers may be saved. This safety issue, I would advise people not to be taken lightly. Saying not afraid of 10,000, but just in case, I suggest you don't buy too cheap mobile power, mobile power supply if you really out of business, you lose.

Millet Note Hat Edition
Millet Note Hat indeed stronger than other phones with the same processor performance, as to whether the legend of "Xiao long version V2.1 810" played a role, we have no idea, but there is no doubt that it does have a lot of advantages in kernel optimization. Millet Note Hat voices to remain consistent and Standard Edition, but more on the transient performance of sound excellent. In addition, the hat to dive at low frequencies also will feel in place, also has some strengthening of sound field.
