ZeroLemon is also offering a belt clip add-on to make your phone and case combo even more functional. It can even double as a sort of kickstand, as you can see in the image above. The belt clip just snaps onto the battery case and the clip can rotate 360 degrees to any position you like. If you snap over the screen side of the phone, you can even get a little bit of extra protection that way.You can get the ZeroLemon 8000 mAh battery case for the S9 and S9+ at Amazon for just $59.99 (link to S9, S9+). The belt clip is also available for $9.99 at Amazon (link to S9, S9+).
