Always feel cheated by selling power bank External battery? power bank External battery doubt to answer

Under the popularization of smartphones in these years, the basic power bank External battery has also become a man's essential items to go out. However, the author's side often complain about the small companion, why 10000 milliamperes charging Po Chong three thousand milliampell phone almost twice? Or power bank External battery why charging for a long time no more. Everyone feels deeply cheated by the store, but in fact most are not.

First, we need to popularize some little knowledge, the core components of the   power bank External battery is the battery cell, then the circuit optimization design.

There are two types of power bank batteries ,: 1, cylindrical, liquid, lithium-ion battery, 18650;

2, polymer. Polymer prices, in theory, the number of cycles more than the former 200-300 times it.

Finished the brand, then why we charge 10000mAh power bank universal for phone only three thousand milliampere phone? Here we have to mention the conversion rate of the problem. It should not be hard for us to understand that the charging of a rechargeable battery is definitely more costly than charging it directly with an adapter.

Let's make a analogy, the charging unit's capacity is milliampere when the common explanation of milliampere is 1w mA when charging treasure, if it discharges with 1A, it can discharge for ten hours (nominal 3.7v case, however The normal charge voltage is 5v). Generally good charging treasure, the conversion rate can only be between 80 to 90 percent, and then add the loss of the charging circuit and heat loss, eventually rushed to the phone, there are 60% to 70% is normal Case.

So to get a longer use of time, not only to choose a better brand of rechargeable treasure, not because of good brand batteries how good, but the circuit design optimization can increase the conversion rate of the battery, while reducing Energy loss. And then of course the big capacity is king. After all, now charge Bao fast charge rampant, greater fever and lower battery life, will affect the final actual use experience.
