What is the battery capacity of the shared power bank?
1. The output voltage of the shared power bank on the market is 5V, and the cell capacity is generally 5000mAh, so the battery capacity is generally about 5000mAh
2. Many mobile phone users will habitually rent a power bank when their phones are out of power. When renting, they pay more attention to the rental price, the capacity of the power bank or the output power. It is normal to care about these things.
3. Some people will also wonder why there is a loss when charging a mobile phone with the power bank, and how much does the loss depend on? In fact, the simple explanation of this question is that there will be resistance and consumption in the charging process. Heating is an obvious loss phenomenon, so there will be power loss in the actual output and input process. Therefore, the actual power input to the mobile phone cannot be equal to the actual capacity of the charging bank. The amount of loss mainly depends on the material, such as the cable of the power bank, the material of the charging cable, and of course, the design of voltage rise and degradation.
Will the shared power bank cause damage to the cell phone battery?
1. Power bank is a charging device that combines the power storage, voltage transformation and charging management method, it acts as a charger and backup battery.
2. Like mobile phones, most power banks use 3.7V lithium batteries as lithium batteries. The charging input of the power bank is 5V DC, and the output is in the opposite direction. Change the average 3.7V working standard voltage of the lithium battery cell of the power bank to 5V output working standard voltage and then transfer it to the mobile phone to achieve the actual effect of charging. In this link, as long as the battery voltage is stably output, the charging of the mobile phone is stable, and it is not easy to cause damage to the mobile phone. Therefore, it is almost impossible to cause immediate damage to the mobile phone by charging it with a reliable power bank.
