Adhesive Thin Metal Plates (4 Pack) for Magnetic Mounts

Best for: users who want a compact set of spare metal plates with strong adhesive and straightforward usage. This kit includes two rectangular plates and two round plates to fit various back surface areas on phones or cases.

Buying Guide
What to consider when choosing a magnetic plate kit
- Compatibility: ensure plates work with your magnetic car mount and with your device’s back surface, whether phone-only or phone-in-case.
- Plate shape and size: rectangle vs. round plates affect where they can be placed on the device for best magnetic alignment.
- Adhesive quality: strong, automotive-grade or 3M adhesives tend to provide longer-lasting adhesion; consider reusability if you switch devices often.
- Non-magnetic plates: many kits include non-magnetic metal plates that work with magnetic systems; magnets are in the mount, not the plate.
- Thickness and weight: ultra-thin plates minimize added bulk and keep devices comfortable in pockets or purses.
- Number of pieces: larger packs save time for multiple devices, cases, or replacements.
- Installation surface: clean, dry, and smooth surfaces maximize adhesive performance and reduce residue on removal.
Frequently Asked Questions
- Do these plates contain magnets themselves? No, most kits provide non-magnetic plates that work with magnets in mounts.
- Will these plates affect wireless charging? Some users report compatibility improvements when used with proper alignment; select ultra-thin or well-placed plates to minimize interference.
- Can I use plates on any phone case? Most cases work, but thick or textured cases may reduce adhesion or alignment accuracy.
- Are replacement plates available if I switch devices? Many kits include multiple plates; additional replacement packs are often sold separately.
- Is installation permanent? Adhesive-backed plates are designed for a secure bond, but you can remove with careful peeling and odor-free adhesive removers.
- Which kit is best for a family with multiple devices? A larger pack (like 8 or more plates) offers flexibility for several phones and cases.
