RE: Personal solar plant. My Actifit Report Card: April 5 2024

mine is w/o powerbank, you charge your mobile directly. Quite stable when walking. But as said, inconvenient for a longer walk if the panels are hooked to the front backpack straps and they bounce off your chest.
I tested it also in a forest - the panels are good, they get the sun even if exposure is not direct (trees shadow) and charging is stable. Given the price - highly recommended.
