I’m looking for a specific kind of MagSafe adapter, but I’m not sure what the correct search term is.
I do not want to stick anything to the back of my iPhone.
What I want is the opposite: a sticker / adhesive magnet / magnet array that I can stick to the back of another object, so that the object itself becomes a MagSafe-style accessory and attaches to my iPhone.
In my case, the object is a small e-ink reader, the Xteink X4. It physically fits very well on the back of my iPhone 17 Pro Max, but its built-in magnets are basically unusable: it slides around and does not stay aligned.
Everything I find online seems to be either:
a metal ring for the back of a phone case
a non-magnetic ring to make a case work with MagSafe accessories
a phone-side adapter, not an accessory-side adapter
What should I search for if I want an adhesive magnetic ring / magnet array / mounting plate that goes on the object, not on the phone?
Would something like a “MagSafe magnetic wall mount sticker” or “adhesive MagSafe magnet array” work for this?
Any specific product names, links, or search terms would be appreciated

I just got an Xteink X4 because I wanted to use it attached to the back of my iPhone 17 Pro Max.

Size-wise, it actually fits almost perfectly on the back of the phone, which is exactly why I chose the X4 over the X3. But the magnetic attachment is basically unusable for me: it slides around and moves away no matter what I do. I’m using the phone without a case, so it’s not a case issue.

Now I’m wondering if the X3 would have been the better choice, even though it’s smaller than the back of the Pro Max.

Since I still really like the idea of using the X4 this way, has anyone found a way to make the X4 more “MagSafe compatible”?

I was thinking of some kind of adhesive magnetic ring / magnet array / MagSafe sticker to put on the back of the X4 itself — not on the iPhone — so that the X4 attaches more securely to the iPhone’s MagSafe magnets.

The problem is that everything I find online seems to be either:

• a metal ring meant to stick on the back of a phone or phone case
• a non-magnetic ring for making a case compatible with MagSafe accessories
• or an official Xteink accessory from their website, which would take a long time to arrive and I’m not even sure would solve the problem

What I’m looking for is basically a sticker or adhesive magnet that would turn the X4 into a stronger MagSafe-style accessory for an iPhone 17 Pro Max.

Has anyone tried this? Any specific product names or search terms that actually worked?
