It has a massive 4,700mAh battery, so you’ll be able to charge your Galaxy S9 from dead to full with this case at least once and then charge it a bit more.

If you don’t want something too thick, but still want the benefits of battery charging, ZeroLemon does an excellent job with the Galaxy S9 Battery Pack Case — it has a 4,700mAh battery in the case that will charge up your Galaxy S9 in a pinch. It’s relatively thin as far as battery cases go. However, it’ll still provide you with proper protection, offering a rubber TPU cover to absorb shock, and then the outer hard battery shell as an added layer of protection. Hit the button on the back to start charging from the case itself.

On top of that, the ZeroLemon Rugged Charging Case has a massive 8,000mAh battery in it that will keep your phone charged at all times.

Using the case itself is easy — take off the top piece of the case, slide the Galaxy S9 into the case itself over the USB-C port, put the top piece back on, and you’re ready to roll!
