The Catalyst Crux case is MagSafe compatible while the Catalyst Influence can go either way. Pictured above are the Crux, Influence without Magsafe, another Crux, and Influence with MagSafe. The Crux adds reinforced corners to the package along with buttons that are hard to press and a cutout for the silence switch that’s hard to get into to actually activate the switch, while the Influence is a simpler affair.
Despite the Crux’s professed MagSafe compatibility, the ridge around the camera bump prevents the iPhone from sitting well on the Intelli Stand. You can basically hook the phone onto the stand using that ridge and the coils align just enough to start a charge, but I wouldn’t bank on that sticking through the night.
Meanwhile, the Influence case has a more subtle look. It has a cutout for impact resistance on the corners. Plus, the Influence case has a knob you can twist to activate/deactivate the silence switch which is admittedly pretty neat. Even if you go with a case that is not MagSafe compatible, you can use either the stand or the battery. There’s just enough magnetism through the back of the case to activate the accessories, but not nearly enough to keep them in place. Best to just use your lightning cable.
