MagSafe is Apple's new wireless charging tech for the iPhone 12 series. It uses magnets to connect the charger to the phone, basically making it a fancier way to plug in your phone with some minor accessory support. While most people assumed it would effectively only work (correctly — as in, magnetically) on the iPhone when it was announced, turns out, that $2000 Z Fold2 actually came with some hidden added value.
