I’ve mentioned the importance of mobile battery backup and charging in a few articles recently (see 10 Travel Photography Essentials and 10 Tips for Better Photography Conventions & Trade Shows), so I decided it was finally time to start taking my own advice. Let’s face it– “getting away from it all” sounds great in theory, but the reality is that most of the time we have to stay connected. And while location shooting, travel, trade shows, chasing down new business, and shuttling my kid from one activity to the next can all be fun and rewarding, they do tend to drain the life force out of phones, tablets, and laptops pretty quickly. While a car charger obviously helps, it doesn’t come anywhere close to solving the problem. That’s why I decided to try the Anker 2nd Generation Astro3 12000 mAh External Battery Charger. In a sleek- lightweight package only slightly bigger than my iPhone, this thing really packs a punch.
