Adhesive Metal Plates for Magnetic Mounts, 5-Piece Set

For drivers who already have a magnetic phone mount but need the metal piece that attaches to a phone or case, this five-piece set offers two rectangular plates and three round ones. The plates are black and have adhesive pre-applied on one side, so you can stick one to a case or place it between the phone and its case.

They are metal plates, not magnets. That distinction matters: they work as the part attracted to a compatible magnetic mount, but they cannot hold a phone on their own. If you want to add a magnetic mounting point without replacing your existing holder, could a spare plate be all you need?

How to use it

Choose a plate shape that suits the area available on your phone or case, then attach it with the adhesive side. The listing describes two ways to position it: on the back of the phone or between the phone and its case. In a car, the plate is intended to pair with a magnetic mount, it is not a replacement for the mount itself.

The adhesive is already applied, which avoids a separate glue step, but placement still matters. Decide where the plate will sit before sticking it down, especially if you plan to move it between cases. The listing does not explain whether the adhesive can be repositioned or reused, so treat it as a fixed placement rather than a removable accessory.

Wireless charging is the main practical trade-off. A plate on the phone or case may interfere with charging, and the listing suggests removing the case when using wireless charging. If you charge wirelessly often, a removable case with the plate attached may be more convenient than sticking the plate directly to the phone.

Pros

• Five plates in two shapes: two rectangular and three round.
• Pre-applied adhesive makes attachment straightforward.
• Designed for use with magnetic car mounts and phone cases.
• Offers a spare-part approach for an existing mount, rather than buying another complete holder.

The main limitation is that you need a compatible magnetic mount already, these plates contain no magnet and do not function as a standalone holder. This suits you if you want a replacement or extra plate for a magnetic setup. Best to avoid it if you need a complete mount or rely on wireless charging without removing your case. Based on the listing, the adhesive is described as strong, but there is no information about repositioning or long-term wear.

There is a size discrepancy in the rectangular measurements as written: the inch and centimetre dimensions do not appear to match. Check which measurement applies to your intended placement before choosing a plate. The round size is also listed in both units, so compare the stated diameter with the space available on your case.

What I’d decide

Choose this set if your current magnetic holder is fine and the missing piece is a plate to attach to your phone or case. The mix of round and rectangular shapes gives you a little flexibility, though there is no information about thickness or how well a particular phone case will hold the adhesive. For a wireless-charging routine, plan around removing the case, if that would be a nuisance, a mounting approach that does not leave a metal plate on the phone may suit you better.
