A day at the beach can turn old school real fast once your devices have run out of juice. But if you’re like us and want to keep the party going as long as possible, we recommend using personal solar panels such as SunStream Energy’s Pro 6 watt solar charger. Portable and submersible, the panels can charge smartphones and tablets in just a few hours (assuming there’s sun) or power packs if you want to store energy for when the sun goes down. From beaching to boating to hiking and golfing, these panels are super portable and can keep you powered up when you’re off the grid. In fact, one of SunStream’s corporate missions is to help people around the globe have access to inexpensive sources of energy. In fact, they’re helping communities in Africa power up and stay connected even without the infrastructure the rest of us take for granted. Be smart and go solar. $39.99. sunstreamenergy.com
