11 Must-Have Gadgets For Your Summer Adventures

With the right accessories, you can blast your favorite tunes poolside or post a beach selfie (#hotdoglegs forever) without worrying about sand and water ruining your phone or tablet. We tracked down 11 great pieces of tech gear that will help make for fantastically fun summer days, whether you're heading to a park across town or sparkling white-sand beach across the globe.

Our picks include the best e-reader for your beach reads, a battery charging pack that will get you through a multi-day music festival in the desert, and a phone case that lets you bring your phone with you when you go swimming or snorkeling (if you can work up the courage, that is — we're still terrified by the idea of submerging a phone in water). We tracked down a portable margarita maker too, because, duh.
