How long does the Power Bank take to be fully charged by sunlight?Updated 2 years ago
Since its solar output is 280mA per hour we can measure the theoretical charging time for your reference:
We test the solar charging in 25000 LUX sunlight intensity, we let the solar panel face the sun for 2.5 hours.
2.5 h X 280mA=900mAh (also guarantee the same light intensity in 2.5 hours).
In this way, it takes at least 5 hours to reach 2000mAh, which will generate 1 bar of electric power for phone charging.
