How long do you know the life of Power Bank?
Today, Xiao Bian to Power Bank's primary users, or ordinary consumer friends brain fill about, professionals do not enter Kazakhstan. Talk about the life of Power Bank. First of all, we should know that Power Bank in the normal circumstances, his use is a certain life, many people in the purchase of Power Bank or before the purchase will think: Power Bank can be used for how long, about how long life? The main need to look at several aspects:
 First: the biggest factor affecting Power Bank's life is batteries. At present Power Bank batteries are generally 18650 or polymer. In many manufacturers product reports, are marked in about 500 times, once on behalf of the charge and discharge cycle once. Power Bank with what batteries, usually the standard imported 18650 A product batteries, such as Samsung, Sony, LG, Panasonic and other use is about 500 times the number of domestic brands such as: BAK, Chong Ming, Desai, Power God is also good. But the second-line brand life in the basic between 300-400 times. The best is the polymer battery, the number of times have more than 500 times. However, if some black heart manufacturers use second-hand 18650 or low-quality batteries, the number of times not only little and even the risk of explosion. So, do not seek cheap to buy some very cheap Power Bank, for the sake of the phone, for their own safety sake.
Second, the greater the capacity of Power Bank, the longer the total life expectancy, because the Power Bank capacitor is usually the greater the amount of time after the use of a longer time, the longer the natural life, the capacity to understand Oh.
 Third: Power Bank PCBA circuit board, the equivalent of the human brain, Power Bank work all rely on the circuit board to control, including working circuits and protection circuits, the use of high-quality circuit board Power Bank more durable, easy to use, more secure ; Contrary to the use of low-voltage circuit board Power Bank, the fault is small, easy to damage the phone, maybe there is the risk of explosion.
Power Bank life-related factors roughly on these, and now we probably know how to judge it? General Power Bank charge and discharge cycle charge in the 300-500 times the value range (mainly based on the current national standard 18650 lithium battery charge and discharge after 300 times, Lithium battery available capacity to retain more than 80%), as many people say that their Power Bank can charge 1000 times, 3000 times, 5000 times, the proposed buyers directly ignored.
Some friends may ask how to measure the number of charge and discharge cycles of Power Bank and Power Bank, which professionals can do, need to aging equipment, even if you know no equipment, it is better to wash it!
 And for Power Bank is no exception, although the current market, most of the Power Bank cut-off voltage are higher than 3.0V, but in our previous evaluation can also be found, Power Bank internal battery voltage has been lower than 3.0V , There are still some products that can continue to provide output capacity until the battery voltage drops to 2.7V or less before closing the output. Like this cut off the voltage set too low product, if it is often used to completely no electricity after the charge, then the internal lithium battery life and capacity will be greatly reduced.
For the newly purchased Power Bank, some careful users also let the Power Bank completely discharged after the Power Bank full power, it is said to keep Power Bank to achieve the best performance when charging. In fact, for the current lithium battery power, as long as two or three times in full charge and discharge cycle to achieve the best performance, experts also suggested that the new Power Bank in the first three times, it is best to extend after full 1-2 Hour, the fourth is full of can be filled, which helps the lithium battery Power Bank to achieve the best performance.
