Thanks for purchasing our MagSafe adapter! You'll obviously need an Apple MagSafe charger puck, they're available at any cell phone store, Walmart/Target, or Amazon. They will work great for iPhone 12 and newer. With iPhones 8-11 and some Androids, those do have wireless charging, but will need a metal ring.
Start off by taking the included Rubber gasket and stretching it around the Apple MagSafe puck. It should be a little smaller so it'll stretch onto it and get a good grip.
The back of the Aluminum adapter has 1/4-20 threaded hole in the center, and can be secured to any of our extension arms.
Optional:
If you have an older iPhone, Android, or just a non-MagSafe compatible case, you may need a metal ring added for the magnets to hold. We offer this as an option, but you can also acquire them elsewhere, I just recommend the rings with the gap (see below), as the full circle rings more commonly available can induce magnetic hysteresis while charging and get a little warm.
