Fall lovers, your time to shine is just around the corner. In the meantime, might we suggest soaking up every last ounce of sun you can? Go for a hike, hit the beach, or flock to a campsite and enjoy the great outdoors. And while you’re at it, you might try harnessing the power of the sun to keep your gadgets alive so you can appreciate your time outside for as long as possible.

This RAVPower Portable Solar Power Bank(opens in a new tab) Features a large solar panel area to soak up the sun and keep your battery topped up while you get in touch with nature. Granted, if you strictly use sunlight to charge it, it will take a week due to the massive 15,000mAh capacity. But luckily, it also includes a micro USB port (and two included cables) for charging with a 5V/2A wall charger. Pro tip: Charge it at home and fill it with sunlight when you’re in the woods.

Talking about its huge capacity, the solar bank can charge two devices simultaneously. Plus, it juices an iPhone at least four times, and a Galaxy 8 at least twice. And of course, since it’s made for the outdoors, it’s rugged enough to handle anything that comes its way — water, dust, shocks, and drops. As a bonus, it also provides a generous amount of light for walking around at night, thanks to an emergency LED. It can be activated or deactivated by holding the power button for three seconds.
