We set up every solar panel in the same open area with full sun exposure to test their direct solar charging speed. Every solar panel was hooked up to its own identical battery and left in the sun for one hour. Then, we discharged every battery, measured the mAh of charge with a digital multimeter, and recorded the results. To measure indirect solar charging speed, we repeated the direct solar charging speed test with a large white sheet suspended above the solar panels in order to simulate a cloudy day. With this simulated cloud cover in place, we hooked up every solar panel to its. To test functionality, we assessed the features that make it more or less easy to use. We assessed how many devices each panel could charge, whether it had features to angle the panel. To test portability, we measured the weight and dimensions of every solar panel. We measured them when folded and set up. We also carried them around and packed them in our backpacks and on our bikes. We set up every panel countless times to evaluate.

The FlexSolar 40W is a high-output, easy-to-use charger that can quickly unfold from the size of a large book into six linked solar panels. This medium-capacity panel has a DC output that can charge portable power stations, as well as USB-C and USB-A outputs for smaller devices.
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 the mountains. Each of the individual panels is only three watts, making 12 watts for the whole setup.
It has two USB-A outputs that can each put out up to three amps, which is enough power to charge any USB device. Roughly the size of a notebook, this solar charger unfolds into three panels and has a zippered case that can easily hold two charging cables, a battery pack, and more.
The more efficient a solar panel is means it can output more watts and amps from a smaller area. For charging devices you'll want a solar panel that's capable of producing at least 5 watts, however many highly portable solar panels produce up to 28 watts of charging power in ideal conditions.
While the FlexSolar 40W does fold down into a small enough package, it's not nearly as light as some of the other portable solar chargers we tested. At 2 pounds 15.25 ounces, it weighs over twice as much as some other panels in the 20-40 watt range.
