Small make up say
Present mobile phone more and more good-looking, screen is bigger and bigger, but the problem of batteries did not catch up with all the time, with charge treasure can alleviate the state with mobile phone insufficient n, but subsequently and the negative news that come also makes popular feeling Jing, charge treasure takes abrupt on the body fume, outfit exploded in the bag... this gives what we resolve a trouble to charge originally treasure, why do oneself become a trouble? Charge can treasure explode really?
Charge the principle of treasure
Charge actually the construction of treasure is very simple, above all inside the most important part is batteries (electric core) . Because of electric core charge input voltage is 4.2 bend over, and charger is 5 bend over, give so charge when treasure charges, need a 5 bend over to charge to the step-down of 4.2 bend over loop; The discharge output voltage of electric core is 3.7 bend over, and mobile phone / flat computer the electronic product that wait, the standard charges voltage is 5 bend over, need a batteries to discharge to the 5V step up that outputs port again so loop. To avoid the occurrence of safe problem, still need core of a report to protect circuit, its purpose is to had prevented to fill, still have current limliting.
Main component is electric core now two kinds, one kind is the electric core of 18650 lithium battery; Another kind is the electric core of polymer lithium battery. The electric core that former batteries uses is charcoal core batteries commonly, the price is low but n is less; Latter good point is n big, charge discharge rate more fast, safe.
As to the word of capacitance, below the condition with same price, everybody wants to buy a capacity bigger. But be sure to keep in mind not to have an insatiable desire for petty gain, the cheapest 18650 lithium battery, a batteries makes an appointment with 2000mAh, the price is 20 about, of 10000mAh charge treasure cost should be controlled 100 pieces at least. . . So the 30~40 on some treasure piece of 10000mAh charge treasure is fake.
Charge the distinction of the 1A on treasure and 2.4A
Export electricity of × of power ＝ voltage
The power of that buccal output of 2.1A is great, charge that is to say fast, but if your mobile phone is to be able to satisfy 0.5 installed electricity, same. Voltaic size depends on with electric equipment, 2.1A can use those who fill flat computer and so on that.
