Any idea how long it takes to charge from empty using the solar panel?
Hello. They don’t state a length of time. Here it is on Amazon:

It shows:
This power bank comes equipped with a solar cell charging panel, allowing you to harness solar energy during sunny summer days. However, please note that the charging time may vary due to uncontrollable external factors like sunlight intensity and battery panel conversion rate. We recommend charging your phone through a power socket before embarking on your travels or hikes, reserving solar charging for emergency situations.
One of the pictures says solar charge serval days via solar panel.
Could mean that it takes several days to charge the pack.
But the math says that the absolute maximum this will charge at peak sunlight is 400 milliamps per hour which would be 25 hours.
Yes what @lquidsnak said…since sunlight isnt 24 hours a day seems consistent with the photo
