Energy storage power supply is one of the essential equipment in modern outdoor adventure and camping activities. It can provide users with enough power to drive various electronic equipment.However, during long-term use, the consumption of electricity is inevitable.Therefore, it is very important to understand how to calculate the power of the energy storage power supply.

Generally speaking, the power of an energy storage power supply can be calculated by capacity and voltage.Among them, capacity refers to the amount of power that the battery can hold, usually measured in milliampere hours (mAh).Voltage is a form of electricity, usually measured in volts (V).Therefore, by multiplying the capacity and voltage of the battery, the total power of the energy storage power supply can be obtained.

For example, taking the Electric general BP1002 outdoor energy storage power supply as an example, its battery capacity is 1120WH, which is approximately equal to 1.12 kWh of electricity.The specific calculation method is: current (battery current) x voltage (lithium-ion voltage) x how many batteries are connected in series = 1120WH≈1.1kWh, where Wh represents watt-hours, which is another commonly used unit of electricity.

It should be noted that due to the influence of factors such as battery loss and circuit conversion efficiency, the power that can be obtained in actual use is often smaller than the total power.Therefore, when choosing an energy storage power supply, the quality of the battery and the quality of the circuit need to be considered to ensure that sufficient power can be obtained.

In addition to the total power, the remaining power of the energy storage power supply is also very important. It can help users understand how much power is left in order to charge or replace the battery in time.Generally speaking, energy storage power supplies will be equipped with LED indicators or digital displays to display the remaining power.When calculating the remaining power, you need to first understand the voltage and capacity of the battery, and calculate the used power through the charge and discharge curve of the battery.
