What MagSafe actually is
MagSafe is a precise array of magnets paired with an NFC chip and inductive coil that lets your iPhone snap into the right alignment for 15W wireless charging.
The magnet grade matters
We use N52 magnets — the strongest grade currently available — to deliver a confident snap that holds your iPhone securely without drifting.
Pass-through wattage
A great VCASE case lets the full 15W reach your iPhone with no thermal loss or interruption. Cheaper cases throttle to 7.5W. We test every product to confirm full pass-through.
