Consumer Reports

The BigBlue 3 goes above and beyond the rest. Thanks to its impressive charging abilities and consistent performance across the board, this panel maintains its place at the top of the pack for another year. Though there may be other options out there that charge faster or look cooler, nothing beats this model when it comes to overall performance. When your electronics need a boost, this panel will deliver a consistent charge in variable conditions &#40;from full sun to partially cloudy&#41;. In terms of features, we love the built-in ammeter and the zippered accessory pouch. We also appreciate this panel's simplicity and reasonable price tag. With three USB ports and a classic fold-out design, the BigBlue is an excellent all-arounder that will efficiently charge most small gadgets. 
One downside to this panel is its weight. Weighing in at 23.5 ounces, it's a bit heavy. As a result, it's better suited for front-country use, though it will excel wherever you use it. Other than its weight, this panel receives high marks across the board.
