The best battery cases in 2021 to keep your smartphone going
As we've become more and more reliant on our smartphones, a battery pack to give your phone an extra boost of power has become essential. Unfortunately, that means having to carry an extra device, adding clutter to your life and just one more gadget to recharge at the end of the day.
The beauty of battery cases is that they'll let you have that extra bit of juice when you need it without forcing you to keep track of yet another device every day. It's a case and a battery pack blended into a single unit, often with passthrough charging so you can charge the case's battery and your smartphone's battery without the need for another port or another cable.
