Magnets that stick are not the same as MagSafe

When a third-party listing says "MagSafe compatible", it is telling you about a magnet arrangement. The accessory will click onto the ring of magnets in a modern iPhone or a magnetic case. That is a real and useful claim, and it is the whole claim. It is not a statement that Apple certified anything.

Apple's own MagSafe is a specific system: a defined magnet layout plus a charging behavior that Apple documents for its own hardware. Separately, the Wireless Power Consortium publishes Qi and Qi2, and Qi2 brought magnetic alignment into the open standard. A third-party accessory may follow any of these, some of them, or simply arrange magnets in a circle so that things stick. The listing rarely distinguishes between those cases, so this site does not pretend it does. Where a claim appears, it appears as "the listing states".

For grips and mounts, none of this matters much: a magnet that holds is a magnet that holds. For charging, it matters a great deal, because magnetic alignment and charging speed are separate things. An accessory can align perfectly and still charge slowly, and a magnetic power bank transfers energy through a coil, which costs more than a cable would.

The practical questions are simpler than the terminology. Does your phone or case have magnets in it at all? If not, a magnetic grip has nothing to hold. Does the case sit thick between the magnet and the phone? Thickness weakens the coupling. And does the accessory need to hold weight, like a car mount over a hard dashboard? Magnets shear sideways more easily than they pull straight off.

One point that is not about convenience: these accessories contain real magnets. If you or someone close to you has a pacemaker, an implantable defibrillator, or any other implanted medical device, follow the guidance published by that device's manufacturer and the advice of your doctor. This site publishes no distances, no thresholds, and no medical opinion of its own. Separately and less seriously, magnets can affect the magnetic stripe on payment cards and hotel key cards.
