The newly bought 10000mAh power bank is best for the first few hours of charging

Don't worry about the lithium battery after it is used up, the lithium battery can be charged and unplugged. As for the "activation" of the newly bought lithium-ion battery, many statements are: the charging time must be more than 12 hours, and it must be repeated three times in order to activate the battery.

This statement that "the first three charges should be charged for more than 12 hours" is obviously a continuation of nickel batteries (such as nickel-cadmium and nickel-metal hydride). So this statement can be said to be misinformation from the beginning. There is a very big difference between the charging and discharging characteristics of lithium batteries and nickel batteries, and it can be very clear that all serious formal technical information emphasizes that overcharging and overdischarging will cause great harm to lithium batteries, especially liquid lithium-ion batteries.

Therefore, it is best to charge according to the standard time and standard method, especially not to charge for more than 12 hours.

So does the battery need to be activated? The answer is yes, it needs to be activated! However, this process is done by the manufacturer, and it has nothing to do with the user, and the user is not capable of completing it.

The real activation process of lithium battery is as follows: the lithium-ion battery shell is filled with electrolyte-sealing-formation, that is, the constant voltage is charged, and then discharged, so that the electrode is fully infiltrated and the electrolyte is fully activated until the capacity reaches the requirements, which is the activation process - volumetric separation, that is to say, the lithium-ion battery has been activated to the user's hands after leaving the factory.

Due to the characteristics of the lithium battery itself, it is determined that it has almost no memory effect. Therefore, the user's new lithium battery does not need special methods and equipment during the activation process.

The lithium-ion battery can be charged at any time and can be unplugged when fully charged.

The first 3 secondary charges are 12 hours. Because I'm useful.

Depending on the situation, the analysis can be carried out as follows:

The charging time of the 20000mAh power bank depends on the input specifications of the power bank

The input of V1A takes about 24 hours.

About 15 hours for V2A input.

About 10 hours for V2A input.

The charging current of the power bank is large at the beginning of charging, and it will turn to slow charging when it is fast and full, so the charging time will be longer than simple calculation.

Power banks are lithium battery cells like mobile phones, and they don't have to be filled or emptied every time. Keep the power from 20 to 100 to 80 per cent, and the battery life is long; Flash the slow charging in the later stage, and the charging time is much faster each time.

The time to fully charge the power bank 20000 mAh is determined by the current of charging, which generally takes 10-20 hours.

1. It generally takes 10 hours to charge a 20,000 mAh power bank with a 9V2A charger.

2. It generally takes 20 hours to charge a 20,000 mAh power bank with a 5V1A charger.

The power bank does not need to be charged for the first time, it can be used directly after purchase, and when the power is used to about 10% of the remaining power, the power bank should be charged in time.

Hello, dear. The 8000ah power bank can be used for four to five hours. The charging time of the 8000 mAh power bank will be different according to the charger, and it can be charged for about 4-8 hours.

1.It takes about 7-8 hours to charge with a charger with an output of 5V-1A and can be fully charged. 2.

It takes about 4-5 hours to charge with a charger with an output of 5V-2A and can be fully charged. When the power bank is charged, it is fully charged, the charging time of the power bank is determined by the capacity and the output of the adapter, 8000 mAh capacity with 1A is the adapter charging, it takes about 8 hours to be full, the capacity divided by the output of the adapter is the theoretical charging time.

iPhone more than 10 times.

The power of the lithium battery is not the effective power, and the power utilization rate of the power bank, that is, the effective power is about 70-75% of the battery power.

The 20,000 mAh power bank can charge the Apple phone more than 10 times, and the ability to charge the phone several times is also related to the capacity of the mobile phone battery. The capacity of the power bank is multiplied by the conversion rate of 75 percent and divided by the capacity of the phone's battery.

The power bank can charge the mobile phone several times, and it is also related to the capacity of the mobile phone battery. The capacity of the power bank is multiplied by the conversion rate of 75% and divided by the capacity of the mobile phone battery, which is the number of charges, and the 20,000 mAh power bank can fully charge the Apple phone more than 10 times.
