Best forYour case is smooth plastic or TPU and your magnetic charger or mount will not latch on.

A cheap fix for a case that blocks magnetic accessories, as long as the case surface is hard and flat enough for the adhesive to grip.

Overview

A pack of three thin metal stickers that add magnetic grip to a phone case that has none of its own. They are not magnets themselves, so they only help once the case sits near a magnetic charger, wallet, or mount.

Wireless chargers and magnetic mounts rely on a metal or magnetic ring hidden in the case; adding one of these to a case that lacks it lets the same accessories start working. The catch is surface: it needs a smooth, flat, hard case such as TPU or PC, since the adhesive will not hold on silicone or textured backs. At 0.55mm thick and 56mm across, it sits under most cases without visibly changing the fit.

  • Outer diameter 56mm, inner diameter 46mm, 0.55mm thick
  • 2.5g per ring, 3-pack in black
  • Sticks to the case, not directly to the phone
  • Peel-and-stick install, cures for 24 hours

Who it's for

Good for anyone who already owns a magnetic wallet, car mount, or charging puck but has a phone case with no built-in ring. Not useful on its own, since it isn't magnetic, so a bare phone or a silicone case won't gain anything from it.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Lets magnetic mounts and wallets work on a case with no ring
  • Thin enough to hide under most hard cases
  • Three included for spares or more than one device
What to check first
  • Only works on smooth, hard case backs
  • Adds no hold at all if the case is silicone or uneven
  • Needs about 24 hours to set before use

Performance notes

The ring carries no magnetic charge of its own; it is a metal disc that a separate magnet grips onto, which is why it must sit directly on the case rather than loose in a pocket. Because it adds ferrous metal close to the phone rather than a magnet, it should not interfere with wireless charging through a compatible case.

Frequently asked

Questions about the Tenoc 3 x Black

Common buyer questions answered straight from the product spec data - no fluff, no "it depends".

Does the Tenoc metal ring make my phone magnetic on its own?

No, it carries no magnetic charge; it strengthens the pull of your own magnetic charger, wallet, or mount once attached to the case.

Will it stick to a silicone phone case?

The maker says no, it needs a smooth, flat TPU or PC case, since silicone and uneven surfaces won't hold the adhesive.

How long before I can use it after sticking it on?

Wait about 24 hours after applying it, per the product's install instructions.
