Solar power generators are recharged using solar panels, so you have a renewable power source that can be generated without any extra cost of operation since the solar panels get the Power from the sun.
It is also important to note that the above-given statistics of solar generator working hours are calculated on 85% efficiency, so they are realistic and cover the capacity loss during operation.
How to calculate the working hours:
Working time = Capacity Wh * 0.85 / operating wattage of your device
This 0.85 represents 85% efficiency.
For example, assuming the power consumption of your laptop is 65 watts.
A Jackery Solar Generator 1000Pro Working time will be 1002Wh * 0.85 / 65 W = 13 hrs.
