Autumn lovers, your time to shine is right around the corner. In the meantime, might we suggest soaking up every last ounce of sun you possibly can? Go for a hike, head to the beach, or flock to a campsite and enjoy the great outdoors. And while you're at it, you can try using 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 features a large solar panel area to soak up the sun and keep your battery topped off while you're getting in touch with nature.
