It doesn't stick strongly enough that you can't push it off with your fingers-- easier to do that one-handed than unplugging a Lightning or USB-C cable.

With a heavier Magsafe charger (like most of the stands out there), you can just lift the phone off and the charger won't come with it. MagSafe's just strong enough to hold a phone on a stand or hold a charger puck to the phone, but not much more.
