took this solar panel with me on vacation so that I could always charge it in remote places. The panel is as expected, very dependent on sunlight. In direct light and strong sun it works wonderfully and can charge the cell phone well. However, every small cloud weakens the performance a little. On very cloudy days, rainy days or even in fog, the performance is correspondingly low. The solar panel is very handy and can be folded up easily. Not all cables fit in the bag after you unfold them for the first time. However, you usually know which cables you want to have with you when you're on the go and can simply leave the rest in the car. The panel can be installed quickly and easily anywhere. I particularly like the fact that the individual panels can be aligned in different directions by folding the solar panel accordingly. This means that even small areas can be used to charge the panel as a whole. The weight is decent and of course cannot be compared with a small power bank. Nothing, but you still have a much more reliable charging battery with you. Simply ideal for traveling. It's worth taking this solar panel with you, especially when the weather is good. In the summer I also used this charging panel at home to save electricity. This worked well and charged the phone. The charging panel was convincing so far and gets a deserved five stars.
