Disclaimer: I bought this product firmly skeptical of the claims about its capabilities. Thus I was not surprised by the results I got. Disappointed? Yes. Surprised? No.The good: It is thin and quite small. It's size is great for portability. It fit snuggly into a small canvas shopping bag.The bad: 100w? I really don't think so. Knock a zero off that and you're much closer. I tried it out this weekend in full, direct, mid-day sun, connected to my Jackery power Bank. The best this unit could muster was 8w.Flexible? Compared to a panel set in an aluminum frame, designed for permanent mounting, this thing is indeed flexible. However, compared to flexible panels with similar specs, not as much. I managed only a few degrees of flex, 12-15 maybe, before I became concerned about damaging it.The unknown: I also was not expecting much quality from the controller provided with the panel. But, as my Jackery already possesses that function, I had no reason to test my impression of the controller.The conclusion: once in a while you discover a product, boasting impressive specs at a steal of a price, that actually lives up to its claims. With that hope, I gave this one a shot. Alas, this is not one of those products. Pity. The company behind it passed up a great opportunity.Charger phone and battery with the charger controller
