Plug a charging cable into the input end of the power bank to charge the power bank, and plug another data cable into the output end of the power bank to charge the phone, so that the power bank can discharge while charging. Because the charging and discharging of the charging treasure are two parts of the circuit, generally speaking, they can work at the same time.
This charging bank has overcharge protection function, that is, after the charge is full, it can automatically power off. This also leads to the power supply of electrical appliances, as long as the electrical appliances do not use electricity, the power is cut off. If you need continuous power supply, you must remove the motherboard of the charging treasure, when the battery is fully charged, directly use the battery power, remove the battery from the charging circuit, and directly supply power to the child's toy car, so that the power supply is not controlled by the motherboard.
First charge the charging treasure, and then discharge the power of the charging treasure, so that even a cycle of charge and discharge.

There are three kinds of lithium battery, ternary lithium ion battery, lithium iron phosphate battery, polymer lithium ion battery, normal lithium ion battery charge and discharge times up to 2000 times.

The number of cycles of the charging bank\/mobile power supply refers to the number of cycles of the mobile power supply that can be repeatedly charged and discharged, generally to retain more than 70% of the total capacity after multiple uses. A cycle refers to charging until the mobile power supply is fully charged, and then discharging (charging the mobile phone, etc.) until the mobile power supply is exhausted, which is a cycle. If the intermediate charge is filled many times before it is full or discharge is discharged many times before it is emitted, it is counted in a cycle.
Plug in the phone and keep charging until the mobile power supply is completely out of power.

2, directly use a resistor to discharge it, manufacturers do aging test is generally used cement resistance. (Plus or minus 10 ohm resistance.)

3. Connect a usb fan in the charging bank to keep it in working state.
