Examples:
Let's say your unit is charged up to 33% . 1/3 of a battery of 500mA battery means you have 167 mA in your battery and you still need 333
mA to reach full charge. On an overcast day, we can estimate a charging rate of 10 mA per hour. If not in use, the solar cell will require 33.3
hours to produce the 333 mA at 10 mA per hour. When in use, the power drain is 0.25 mA per hour. This means that the lling capacity will
be 10 - 0.25 mA per hour which equals 9.75 mA per hour. In this scenario, to reach full charge (100%, 500 mA) it would take 34 hours while
in use.
