MagSafe Chargers buying guides
MagSafe chargers snap onto the back of a compatible iPhone with magnets, so the coil lines up every time. That alignment is the point, because a loose wireless charge wastes power as heat. Check that your phone supports it and that your case is thin or made for magnets. Thick or metal cases can block the charge. Look for a cable long enough to use while holding the phone.
