This panel is great. It charges my smartphone really fast and as long as you have the panel in direct sunlight it is very reliable and powerful. You can hang it on a backpack or tree or just lay it out on the dashboard of your car. This is a $200 product that Sierra is selling for $140 and with all of their discounts I can get out the door with this item for just under $100!!! Good value for the product. The 12V adapter is key as well.

Based on the product description and web description, I bought it to charge my iPhone 3. That did not work. It plugs in fine, but makes the beeping noise once you plug it in, then continues to beep every 2-5 seconds for an hour. Irritating noise. After an hour charging in direct to slightly cloudy conditions, it had less battery charge than when I started. Disappointing performance. The product seems well built, quality construction. Nice grommets for attaching to something like a pack. Nice pocket for the cables. Folds up well. But for $100 or so, it was not what I expected.
