Best Smartphone Charging Cases

These cases keep you charged and protected. What more could you ask for?

Portable chargers are a sensible way to make sure that you'll never get stuck with a dead battery while out and about—but even the slimmest and most compact chargers still require you to carry around an additional gadget. And those wires? Forget about it.


Thankfully, dual-purpose cell phone charging cases can come to the rescue by giving you a streamlined solution while protecting your valuable device at the same time. Look for an option that provides plenty of juice while not interfering with your phone's features. Battery life will be the least of your worries!
