Answer formula 1:? The voltage of the cell depends on the specific model and specification. 1. Charging treasure usually uses lithium battery as the battery cell, the common voltage is 3.7 volts and 3.6 volts. 2. Some high-capacity power banks may use multiple cells in parallel to provide greater power output capacity, and the voltage may be higher. 3. In addition, the charging and discharging voltage of the charging bank may be adjusted according to the design requirements to provide better adaptability and charging efficiency. It should be noted that the battery voltage used for the charging bank is usually not directly output to devices such as mobile phones, but is converted and controlled through the internal circuit chip to ensure a safe and stable power output.
If you want to know the battery voltage of the specific charging bank, please refer to the product manual or relevant specification information.
3.7 volts.
The power bank is a portable charger that can be carried by individuals and can store electrical energy itself, mainly for handheld mobile devices and other consumer electronic products (such as wireless phones, laptop computers) to charge, especially for occasions without external power supply, the battery is generally 3.7 volts.
