Why Choose GDMINLO Metal Plates?

If you rely on a magnetic car mount daily, the right metal plate makes the difference between an unstable phone and a secure, hands-free setup. GDMINLO plates balance strength and discretion: they’re strong enough to hold through bumps and turns, while remaining thin and easy to conceal under or inside a case.

Driver-Friendly Benefits

  • Quick, secure mounting and removal for safer driving.
  • Multiple plates let you keep one in the car, one on a work phone, and spares for family devices.
  • Low profile preserves wireless charging compatibility when used with compatible cases (test with your device).

Installation & Placement Tips

  1. Clean the phone or case surface with an alcohol wipe; let it dry completely.
  2. Peel the 3M backing and position the plate centered behind the phone or inside the case where your mount makes contact.
  3. Press firmly for 30 seconds to secure the adhesive; allow 1–2 hours for full bond strength.
  4. Test mount strength before driving; move plate position slightly if alignment with your mount isn’t optimal.

Tip: If you use wireless charging often, place the plate slightly off-center or test with your specific charger—some setups remain compatible, others may require removing the plate before charging.

Frequently Asked Questions

Will these plates work with all magnetic car mounts?

Yes — the plates are designed to be universally compatible with magnetic mounts (dashboard, vent, and other styles). For best results, match plate placement to the magnetic contact on your mount.

Can I remove the plate without residue?

These plates use strong 3M adhesive that’s intended to be secure. They’re not designed for frequent removal; if you do remove a plate, some adhesive residue may remain depending on the surface. Use an adhesive remover if necessary.

Does the plate interfere with wireless charging?

Because the plates are metal, they can interfere with wireless charging in many phones. If wireless charging is important, test charging after installation or place the plate in a location that avoids the phone's charging coil.
