No matter how you slice it, keeping some extra battery power on your person can do wonders to affect how you move through the world. If you’d like to take some concentrated electricity around for emergencies, you’ve got two options:
Both charge your devices, and both require charging themselves. But where one trades functionality for convenience, the other ditches the one-size-fits-all approach in favor of a bespoke battery for your smartphone.
I carry around a battery pack with really short cables simply because I carry more than my smartphone. My Bluetooth headphones and my digital camera are always in my bag, but aren’t always removed when the batteries die. That’s where the external battery pack comes into play. A near-infinite variety exist, from packs that will fit in your wallet to huge blocks that can charge your devices multiple times over before needing to see an outlet. Mine fits in the palm of my hand and can charge my phone at least twice.
