The battery of the power bank is usually an 18650 lithium battery with a voltage of 3.6 volts. They are connected in parallel and then connected to the primary (input end) of the power converter. The voltage of the entire primary is 3.6V, which is increased to 5V by the power converter to charge the mobile phone. In other words, even a single 18650 battery can be used, but the charging time of your cell phone is very limited. When multiple batteries are connected in parallel, it's like going from a swimming pool to a tank, even if the water level and depth vary. not changed. , but when the water surface is wider, the stored water is greatly increased, and the ability to provide external water supply is much stronger (for power banks, the ability to provide external water supply is much stronger). If a serial connection is used,the primary voltage is 3.6X6 = 21.6V Haha, I don't know if such a high input voltage can make the power converter work normally. The correct connection method should be:
