The total nominal capacity of 20000mAh for the internal battery cells of the portable charger is measured at a voltage of 3.7V.
2. The standard voltage for charging devices such as mobile phones is 5V. During the discharge process, there is a step of voltage boosting and conversion, which inevitably results in energy loss.
Therefore, the actual effective output capacity of a portable power bank is approximately 60%-70% of its nominal total capacity.
4 Its actual charging capacity for devices is approximately 12000-14000mAh (specific values may vary depending on the device and usage environment)
