BigBlue SolarPowa 28The BigBlue SolarPowa 28impressed our testers with its ability to balance portability and solar charging efficiency better than any other solar panel we tested. This model has impressive solar charging abilities in both direct sunlight and during cloudy days, and it weighs less than all but the smallest 5-watt panels. It unfolds into four solar panels quickly and easily, and it's light enough to prop up or hang off of just about anything to get an ideal charging angle to maximize efficiency.X-Dragon 20WThough the zippered pouch on the X-Dragon 20W makes storing your charging cables easy, it does make it harder to lay this panel completely flat on the ground. A canvas flap secures on top of the mesh zippered pouch. This flap, along with the pouch, make it so the panel sits at an awkward angle when you try to lay it flat.

This doesn't have any velcro, magnets, or other clasps to deal with when folding and unfolding this panel, which makes it very easy to set up. And it's just as easy to take down when you're done charging. It has a DC output capable of putting out 19 volts of power, so it's capable. Goal Zero Nomad 5The Goal Zero Nomad 5is our top pick if portability is your top priority. This panel is small enough to take backpacking. It's incredibly thin and remarkably durable. Plus, it only weighs 12.35 ounces. This panel weighs less than many larger battery banks that you might otherwise bring on an extended trip so that it could save you weight in your pack. It doesn't fold but is thinner than average and has a single kickstand leg to angle it at the sun. This lets you maximize the efficiency of thi. Hiluckey HIS025 25000mAh Power BankWe've been testing solar panels with integrated batteries for years, and most of the power bank/solar panel combos we've tried haven't performed well as solar panels. However, the Hiluckey HIS025 25000mAh Power Bankuses a newer design that makes it perform better as a solar panel. This power bank features a four-panel fold-out solar array. And while it still won't fully charge your entire base camp, it will work better to keep your phone and other small tech topped off for a long weekend in t.
