My army of portable chargers is eight soldiers strong. It’s a little ridiculous, but the variety gives me flexibility to pick the perfect charger for the day’s needs, whether it’s my sleek MagSafe charger to keep my iPhone going on longer days or a bigger brick for my iPad, camera, and other devices when I anticipate heavier usage. My collection ballooned as charging tech improved over the years, but it’s way more than any one person needs.
