In between getting directions to the venue and hashtagging your entire wedding, your guests' batteries can run low really fast. That's why we love this idea that we came across (on Instagram, of course) from wedding planner Mindy Weiss [2]: a charging station to keep phones fueled until the party stops. We're pretty sure guests will all appreciate it, and you can even DIY your own [3] to make it fit right in with the rest of your decor. Genius!
