How to correctly choose mobile power

Mobile power is really a good product, largely solved out charging our worries!
But how to choose a good mobile power? The first recruit: the capacity, the judgment. Foreign imports of a-class lithium-ion batteries A maximum capacity of 2800 mah/section, domestic top 2200 mah/section. Polymer batteries capacity up to 3500 mah/section. When the thickness of the mobile power supply more than 18 mm, capacity is higher than domestic or imported high multiples of too much, their capacity of qi, the actual capacity is not so big!
The second recruit: the size, judge the type of batteries, 18650 battery to 18 mm in diameter, 65.0 mm high. When the thickness of the mobile power supply more than 18 mm would be 18650 batteries, and there is no limit to the shape of the polymer batteries is thin, generally as a square, better recognition. 18650 more expensive relatively polymer batteries, polymer batteries, security is much higher.
Three recruit: the price. When the businessman speak own mobile power supply is the large capacity, polymer batteries, and the price is too much lower than the general manufacturer, there must be some problem. Is likely to be empty mark capacity, it is possible that using cheap more bad of the batteries, it is definitely a great hidden trouble for security. All the mobile power generated by superposition of series of large capacity, as long as we are sober judgment when shopping, don't just look at the price and make good of the things you can't buy real.
Minas, science and technology, focus on lithium battery energy environmental protection products, electric vehicle batteries, LED flashlight Jane battery, battery, LED lamp. For corporate diversification, innovation, efficiency, introduction of mobile power products. Finished product department team has many years of experience in research and development of technical personnel, every mobile power supply finished products through strict inspection, to ensure sufficient capacity enough, improve safety performance!
Sweet little knowledge: 18650 battery (lithium battery) the batteries as cylindrical, safety performance is low, not suitable for high rate charge and discharge, so generally used for small capacity mobile power (below 10000 ma). Finally said that the conversion rate, conversion and use of mobile power supply circuit board is relevant, mobile power supply voltage is 3.7 V batteries itself, which is 5 V, to charge the mobile power have to step up to 5 V, this process will loss a lot of power, about 35% power loss, good circuit boards in general will reach 40%, mobile power supply safety protection will be loss of power, now better mobile power supply circuit board is soft board, namely can write to control in the above code, reasonable distribution of current and voltage, stable working condition, prolong service life! Mina, science and technology, mobile power supply adopting soft board PCB, very good advantage is the power charge will automatically disconnect. There are hard, this is no control code, a lot of power explosion problem is to use this kind of circuit board production.
