Each rectangle measures 1.77 by 2.56 inches, and each round plate has a 1.57-inch diameter. The adhesive-backed plates are designed to adhere to the outside or interior of a phone case, giving the mount's magnet a surface to attract. Their black finish also makes them relatively inconspicuous on dark cases.
The main trade-off is charging compatibility. The manufacturer warns that a plate attached to the back of a phone or case may disable wireless charging and suggests removing the case during charging. It is also important to understand that these pieces are not standalone magnets; they need a magnetic phone mount to provide the holding force.
This set is a strong recommendation for a driver or household that wants several replacement plates without committing to a very large multipack. The range of shapes, straightforward installation, and generous count make it especially suitable for users who own multiple phones or need spares for a car, home, and work setup.
Useful Shape Selection
Mixing round and rectangular options makes the set adaptable to compact mounts, larger cradle assemblies, and phones with different amounts of usable back surface. Users can also keep a spare plate in a case or travel bag without taking up much room.
Simple Case Installation
The plates can be applied to the back of a phone or case, although placing one between the phone and case can reduce visual bulk. Cleaning the bonding surface before application helps the adhesive establish a more consistent connection.

2. WixGear Metal Plate 4 Pack – Best Compact Multi-Device Set
WixGear Metal Plate 4 Pack
Four total mounting plates
Two rectangular, two round
Strong adhesive backing
Black universal plates
The WixGear Mount Metal Plate 4 Pack offers a compact way to add a magnetic attachment surface to a phone, tablet, or case. Its 4.6 rating and mix of two rectangular and two round plates make it useful for users who need a few functional replacements rather than a large service kit.
Pros
- Compact four-plate quantity
- Multiple shape options
- Suits several device types
- Quick adhesive installation
Cons
- Fewer spares than larger sets
- Wireless charging placement matters

The product data emphasizes compatibility with magnetic phone and cradle-less mount systems. Each plate has a strong adhesive backing, and the simple peel-and-stick process can be used directly on a device or case. This makes the set practical for replacing a damaged plate or preparing more than one device for magnetic mounting.
Its smaller quantity is the principal limitation. Two plates of each shape leave less room for mistakes, multiple cases, or several mounting locations. The mounting surface must also be clean and suitably smooth, while users should keep any plate positioned away from a wireless charging sensor if they rely on that charging method.
The WixGear set is a sensible option for someone who needs a small, focused supply of universal metal plates. It particularly suits owners of a magnetic car mount who want a few spares or need to equip two devices without buying a much larger bundle.
Flexible Device Coverage
The product is presented as compatible with a range of phones and magnetic systems, making it a practical general-purpose kit. Its value lies in offering both larger rectangular and smaller circular contact areas for different mount designs.
Quick Replacement Setup
A compact four-piece kit is useful when a plate has peeled away or scratched. Keeping one shape in each case provides a practical backup without requiring a large storage footprint.

3. Scosche MagicMount Replacement Kit – Best for Durable Car Mounting
Scosche MagicMount Replacement Kit
Two large metal plates
Automotive-grade adhesive
Cleaning wipes included
Not MagSafe compatible
The Scosche MagicMount Replacement Metal Plate Kit stands out for users who want a dedicated automotive mounting solution. It carries a 4.6 rating, includes two large metal plates, and describes its adhesive as automotive-grade for use through changing heat, cold, and daily driving conditions.
Pros
- Designed for temperature variation
- Large contact area
- Includes cleaning supplies
- Backed by limited warranty
Cons
- Only two plates included
- Not compatible with MagSafe
We may earn a commission when you buy through this link, at no additional cost to you.
The plates attach to a phone or the outside of a case and provide the ferromagnetic surface required by a magnetic phone holder. Scosche states that the kit works with dashboard, windshield, CD-slot, and vent mounts. Cleaning wipes and a user manual are included, making the installation package more complete than a simple loose set of stickers.
The manufacturer recommends placing the plate directly on the device or outside the case, then waiting 24 hours before attaching the magnetic mount. It is also explicit that the kit is not compatible with MagSafe. That limitation matters for buyers who want a plate that can double as part of a MagSafe-style accessory arrangement.
This is an excellent choice for a car owner who values documented adhesive resilience and large replacement plates. The two-piece count is modest, but the installation guidance, included supplies, temperature-conscious construction, and limited three-year warranty justify considering it for a primary vehicle mount.
Automotive Temperature Readiness
A car dashboard can become substantially hotter than the surrounding environment, while a parked vehicle may also experience cold conditions. The automotive-grade adhesive is specifically presented as capable of maintaining its bond through those temperature changes.
Careful 24-Hour Installation
The recommended wait time allows the adhesive time to settle before the plate receives the repeated pull of a magnetic mount. Following the cleaning and placement instructions can improve consistency, especially on smooth glass or plastic surfaces.

The set combines wide rectangular strips with circular iron plates, all using double-sided adhesive. Product information describes them as rust-free steel pieces with protective liners, and notes that the larger construction is intended to improve holding strength. The variety makes the kit useful for phones, tablets, GPS units, and portable monitors.
The product data is unusually detailed but somewhat dense, so buyers should identify the relevant plate dimensions before installation. A larger metal area can improve magnetic engagement, but it may be less suitable for small phones or tightly fitted cases. The manufacturer also advises keeping the plate away from the wireless charging sensor.
The volport set is a strong recommendation for a multi-device household or a driver who wants spares for several mounting positions. Its broad mounting range and ten-piece count offer more flexibility than small four-piece kits, provided users select an appropriate size and maintain awareness of charging placement.
Multiple Mounting Configurations
The mix of strip and disc geometry can suit cradle-style holders, vent mounts, and stands with different magnetic contact patterns. This variety is useful when a single plate shape does not sit well within the available area on a case or device.
Useful Spare Coverage
Ten pieces provide enough inventory to equip several devices or retain replacements after a plate becomes damaged. A spare can be particularly valuable for a frequently used car mount, where repeated attachment and removal may place more stress on the adhesive edge.

Adhesive-backed installation
The S-07N Adhesive Thin Metal Plates set offers a small, uncomplicated package for equipping a phone or case with magnetic-mount compatibility. It has a 4.5 rating and includes two rectangular plates measuring 4.5 by 6.5 centimeters and two round plates measuring 4 centimeters in diameter.
Pros
- Compact four-piece format
- Rectangles and discs included
- Easy installation process
- Fits inside suitable cases
Cons
- Limited spare inventory
- May interfere with wireless charging
We may earn a commission when you buy through this link, at no additional cost to you.
The manufacturer states that the strong adhesive can be used on the back of a phone or between the phone and case. Placement inside a compatible case can make the plate less visible and preserve a cleaner exterior, while the supplied shapes offer options for different mount geometry and device sizes.
The main concern is wireless charging. The product information specifically warns that attaching a plate to the back of a phone or case may disable wireless charging. It is also worth remembering that the plates have no magnetism of their own and function only when paired with a suitable magnetic holder.
This set works best for a user who has one phone, one case, and one primary mount. Its compact dimensions and mixed shape selection make installation flexible without filling a drawer with replacements, but people managing several devices may prefer a larger multipack.
Discreet Case Integration
Placing the plate between the phone and a sufficiently roomy case can keep the exterior looking largely unchanged. Users should check the case's interior dimensions first to ensure that the plate will lie flat.
Compact Shape Options
The round plates can fit around smaller attachment areas, while the rectangular pieces offer a broader face for cradle-style magnets. Having both shapes is useful when one mount geometry does not cooperate with a particular case.

6. SALEX Replacement Plates 16 Pack – Best Extensive Replacement Kit
SALEX Replacement Plates 16 Pack
Sixteen total mounting plates
Rectangular steel construction
3M adhesive backing
0.5 millimeter thickness
The SALEX Replacement Metal Plates 16 Pack is a comprehensive backup kit for people who use magnetic mounts regularly or want plates for several phones and cases. Its 4.5 rating, large inventory, and 3M adhesive backing distinguish it from smaller four-piece sets.
Pros
- Generous sixteen-piece inventory
- Very thin steel profile
- 3M adhesive construction
- Suitable for many device types
Cons
- Rectangular-only plate format
- No stated round-disc options
We may earn a commission when you buy through this link, at no additional cost to you.
Each plate measures 2.56 by 1.77 inches and is 0.02 inch, or 0.5 millimeter, thick. That low profile can help the steel sheet fit discreetly inside a case, and the product description states that the edges are designed not to damage fingers or a device. The rectangular format is consistent throughout the set.
Because the package contains many identical rectangular pieces, it may not satisfy someone seeking a mixed assortment of shapes. The listed thickness should also be considered alongside very slim cases, where even a small plate can create a noticeable step. Placement behind a battery cover, inside a rugged case, or between a device and case may be more practical than attaching directly to the phone.
The SALEX kit is an excellent choice for a multi-phone household, a collection of cases, or anyone who wants an ample supply of thin replacement plates. The sixteen-piece count makes it particularly attractive for equipping more than one mounting location, while the 3M backing and low-profile dimensions support discreet daily use.
Large-Scale Spare Supply
Sixteen plates allow users to prepare several devices without repeatedly reusing the same adhesive surface. This is helpful for families, shared vehicles, or a user who replaces cases frequently and wants a ready plate for each one.
Low-Profile Case Fit
At 0.5 millimeter thick, the rectangular sheets are designed to avoid excessive bulk. Buyers with tight-fitting cases should confirm that the interior can accommodate the sheet without forcing the case closed unevenly.

7. 24 Pack Metal Strips – Best for Non-Steel Vent Mounts
24 Pack Metal Strips
Twenty-four narrow metal strips
2.3 by 1.1 inches
0.02-inch thickness
Non-steel vent support
The 24 Pack Adhesive Metal Plates for Magnetic Mount is built around narrow rectangular strips and a high plate count. Its 4.6 rating and two-shape dimensions make it an interesting choice for multiple vehicles, many magnetic mounts, or replacement stock for frequently used cases.
Pros
- Highest plate count listed
- Narrow strips suit tight spaces
- Useful for non-steel vents
- Designed for easy application
Cons
- Narrow shape may cover less
- Charging compatibility requires care
We may earn a commission when you buy through this link, at no additional cost to you.
Every strip measures 2.3 by 1.1 inches and is 0.02 inch thick. The small profile is intended to fit discreetly inside a phone case and the strong adhesive backing is described as allowing removal without sticky residue. The product data also specifically identifies aluminum and plastic vent surfaces as a use case for the plates.
Narrow strips may provide less contact area than larger rectangular plates, and their suitability depends on the shape and strength of the mount's magnet. Although the product description notes wireless-charging-friendly positioning, users should still keep each strip away from the charging coil. The set is also all rectangular, with no round option included.
This 24-piece set is a strong recommendation for users who need many inexpensive-format spares or whose vent mounts attach to non-steel surfaces. Its narrow dimensions are especially useful where a full-size plate would be awkward, while the large count supports extensive multi-device coverage.
Support for Plastic Vents
Plastic and aluminum vent slats do not inherently provide the same magnetic attraction as steel. An adhesive strip can create a localized ferromagnetic surface that gives the mount's magnet something to grip.
High-Volume Replacement Flexibility
Twenty-four pieces make this set useful for several cars, several cases, or a user who wants to avoid running out of replacements. The individual strips also remain easy to store in a glove compartment, desk drawer, or travel kit.

DSTELIN 12 Pack
Twelve total mounting plates
Six rectangular, six round
Strong adhesive tape
Black universal design
The DSTELIN Smartphones Metal Plate 12 Pack is a balanced multipack that gives buyers six of each plate shape. Its 4.6 rating, even shape distribution, and strong adhesive tape make it well suited to users who need replacements for multiple phones, cases, or magnetic mounting positions.
Pros
- Equal shape selection
- Twelve useful mounting pieces
- Simple adhesive installation
- Works with magnetic holders
Cons

We may earn a commission when you buy through this link, at no additional cost to you.
The rectangular plates measure 1.77 by 2.56 inches, and the round plates have a 1.57-inch diameter. They can be attached to the exterior of a device or case using the included adhesive, providing the metal surface needed by a magnetic mount. The black finish helps them blend into common dark cases.
The manufacturer warns that a plate on the back of a phone or case may disable wireless charging, so the product should be positioned or installed according to the charging requirements of the device. Users should also remember that the pieces are not magnets on their own and need a compatible magnetic cradle or holder.
This set is a strong recommendation for a household with more than one phone or for a driver who prefers keeping multiple spares. Compared with the smaller four-piece set, the twelve-piece configuration offers better shape coverage and a useful buffer without reaching the size of the largest multipacks.
Useful Equal Shape Balance
Six rectangles and six discs give users equal flexibility without deciding which shape is most important. The user can compare both against a mount's magnet geometry and keep the better-performing shape for each device.
Practical Spare Supply
A dozen plates make it easy to equip a second case or replace a worn piece. Because adhesive plates may be exposed to repeated handling, keeping a few unused spares is a sensible habit for frequent mount users.

Great 1 Universal 12 Pack
Twelve total mounting plates
Six rectangular, six round
3M adhesive backing
Paper-thin profile
The Great 1 Universal Metal Plates set is notable for its paper-thin construction and focus on a clean, low-profile attachment. It has a 4.5 rating and includes six rectangular and six round plates, giving users an ample selection of shapes for magnetic car mounts.
Pros
- Very low-profile construction
- Smooth rounded plate edges
- Removes without sticky residue
- Convenient one-hand mounting
Cons

- Exact dimensions are not supplied
We may earn a commission when you buy through this link, at no additional cost to you.
The manufacturer highlights 3M adhesive for a stable, long-lasting hold and describes smooth edges intended not to scrape the user's hands. It also states that the plates install and remove without leaving sticky residue on a phone or case. The thin construction can make the device feel nearly unchanged when a plate is hidden inside a compatible case.
Exact plate dimensions are not included in the supplied product information, so checking the current listing is important for buyers with tightly fitted cases. Because the plates are magnetic-mount accessories rather than charging components, positioning should still be chosen with the device's wireless charging area in mind.
This set is a strong recommendation for users who prioritize a nearly invisible profile and straightforward removal. It is particularly useful for anyone who changes cases often, since a spare plate can be moved to the next case without leaving adhesive behind on the device.
Virtually Invisible Plate Profile
A paper-thin plate can disappear inside a compatible case, preserving the exterior appearance while providing a magnetic surface. This is useful for users who want the functional benefits of a mount without a visibly bulky attachment.
Smooth One-Hand Handling
The product data emphasizes smooth edges and easy handling. This helps keep the installation comfortable and reduces the chance that a raised edge will catch a fingertip while attaching or removing the phone.

10. OWLKELA 10 Piece Set – Best Silver Multi-Size Option
OWLKELA 10 Piece Set
Ten total mounting plates
Four rectangular, six round
3M adhesive backing
Silver surface finish
The OWLKELA 10 Pcs Mount Metal Plate set provides a varied assortment of silver rectangular and round plates. Its 4.5 rating and 3M adhesive construction make it a credible option for users who want enough replacements to cover several phones or magnetic mounts.
Pros
- Two plate sizes included
- Protective film must be removed
- Strong 3M adhesive
- Works with multiple devices
Cons

We may earn a commission when you buy through this link, at no additional cost to you.
The package includes four rectangular plates intended for larger phones, tablets, and GPS devices, plus six smaller round plates for compact devices or smaller magnetic systems. The ultra-thin design is intended to remain nearly invisible, while the smooth surface is described as helping protect the phone from scratches.
One important installation detail is the blue protective film on the silver plate. It must be removed before the plate is attached; leaving it in place can prevent both proper bonding and direct metal contact with the mount. The plates should also be placed away from the wireless charging sensor.
The OWLKELA set is a good recommendation for users who want multiple sizes without a large twelve- or sixteen-piece inventory. It is particularly useful for a mix of larger navigation devices and smaller phones, provided the protective film is removed and the plates are positioned thoughtfully.
Two Sizes for Mixed Devices
The four rectangular plates offer a larger bonding and contact surface, while the six round plates suit smaller devices or compact mounts. This combination is useful for a driver who alternates between a phone and a GPS unit.
Remove the Protective Film
The blue film protects the silver surface during shipping and storage, but it must be peeled away before adhesion. Checking for the film immediately after opening prevents a failed first installation.

Buying Guide – How to Choose the Best Adhesive Metal Plates for Phone Mounts
The best adhesive metal plate depends on the mount's magnet, the device and case dimensions, the installation environment, and whether wireless charging is important. Use the following factors to narrow the options before ordering a replacement or multipack.
Plate Shape and Surface Area
Rectangular plates generally provide a larger, more continuous surface for a cradle-style magnet, while round plates can fit compact holders, small spaces, and cases with limited flat areas. The two formats are not interchangeable for every mount because the magnet's shape and footprint determine where the plate must sit. A broad plate can improve magnetic engagement, but it may not fit neatly within a thin case or a particular camera surround. A small round disc can be easier to position but may not deliver the same holding area as a larger rectangle.
Mount and Device Compatibility
These products are generally intended for magnetic phone mounts rather than every magnetic accessory on the market. A universal mount may work with a rectangular plate, a round disc, or both, but the holder's magnetic face should be checked before installation. Device size also matters because a plate that extends beyond the back of a small phone can look unbalanced or interfere with the case. Tablets, GPS units, and larger phones may benefit from more surface area and stronger adhesive, while a small handset can often use a smaller disc.
Adhesive Type and Durability
Strong adhesive is essential because a magnetic holder creates a sustained pull at the plate's center. Several products in this guide specify 3M adhesive, while the Scosche kit describes its adhesive as automotive-grade. Adhesive brand alone does not reveal every performance characteristic, so installation conditions remain important. A clean, dry bonding surface usually produces a more consistent result than applying the plate over dust, moisture, or textured case material. Heat, cold, vibration, and repeated removal can all affect how long a bond lasts.
Profile Thickness and Case Fit
A low-profile plate is less noticeable and can be hidden between the device and case. Several options measure 0.02 inch, or 0.5 millimeter, while one product describes a paper-thin construction. The smallest stated thickness does not automatically make a plate compatible with every case. Interior clearance, camera bumps, battery covers, and the phone's own curvature can affect whether the case closes comfortably. Users who prefer a nearly invisible installation should compare the plate dimensions with the available space inside the case.
Wireless Charging Clearance
Wireless charging requires an unobstructed path between the charging pad and the device's charging coil. A metal plate positioned over that coil may prevent charging or reduce the apparent effectiveness of the setup. Several manufacturers explicitly warn against this placement, and the Scosche kit is not compatible with MagSafe. Buyers who depend on wireless charging should identify the coil location and position the plate toward the upper or lower portion of the device where appropriate, provided it remains within the mount's magnetic field.
Pack Quantity and Replacement Needs
Pack size should reflect the number of devices, cases, and mounting locations in use. A four-piece set is enough for a single phone and a spare or two, while ten- to sixteen-piece kits suit households with multiple devices or vehicles. The 24-piece strip set offers the largest inventory and can be useful for non-steel vent applications. More plates are not always better if the shapes do not match the mounts, so buyers should estimate how many useful pieces they need rather than focusing only on the total count.
Installation Surface and Location
The adhesive will usually perform better on a smooth, rigid surface. Phone backs and many cases provide suitable faces, but textured, soft, or flexible materials may not create a reliable bond. Vent slats deserve special attention because plastic or aluminum does not attract a magnet on its own; a small plate attached to the slat can create a better magnetic contact area. The product must also remain within the magnetic mount's attraction zone without preventing the vent from opening or closing fully.
Included Installation Accessories
Some kits include more than loose metal pieces. The Scosche set provides cleaning wipes and a user manual, and it includes a protective film intended to reduce damage and residue. The volport set includes clear protective liners. These extras can improve the installation process by giving users a clean surface and clear handling instructions. Other multipacks are simpler and focus on quantity, which may be preferable when a buyer already knows how to install a plate and wants a larger inventory.
How to Use and Care for Your Adhesive Metal Plates for Phone Mounts
Start by choosing the correct shape and confirming that the plate is a replacement accessory for the magnetic mount in use. Clean the back of the phone or the intended case location with a suitable cleaning material, then let the surface dry completely. Position the plate where the mount's magnet will make full contact while keeping it away from cameras, buttons, ports, and the wireless charging coil.
Peel away the protective liner or film, align the plate carefully, and press it into place with even pressure. Avoid touching the adhesive after positioning it. For products that specify a settling period, such as the Scosche kit's 24-hour recommendation, wait before attaching the magnetic mount so the bond can establish under less immediate stress.
For care, remove the phone from the mount before lifting it away rather than pulling sideways against the adhesive. If a plate must be removed, peel it slowly and clean any residue from the case. Store unused plates in their original packaging, and replace a plate if the adhesive edge lifts, the surface becomes contaminated, or the mount begins to shift under normal use.
Frequently Asked Questions
Are adhesive metal plates for phone mounts magnetic themselves?
No. The plates in this guide are generally non-magnetic steel or iron pieces that provide a surface a separate magnet can attract. They need a compatible magnetic phone mount to hold a device in place. Calling them magnetic plates is common shorthand, but the mounting force comes from the holder's magnet rather than the adhesive plate.
Where should I place the metal plate on my phone?
Place it on the back of the phone or case where the mount's magnet will make solid contact. It should be flat, away from raised camera areas, buttons, and ports, and positioned outside the wireless charging coil. If the case has enough interior room, placing the plate between the phone and case can reduce visible bulk.
Can I use these plates with wireless charging?
You may still use the plates, but they must be positioned away from the wireless charging sensor. A metal plate over the charging coil can disable wireless charging. Users should check the device manufacturer's charging guidance and confirm that the plate does not interfere with the intended charging position.
Will an adhesive plate fit inside my phone case?
It depends on the case's clearance and the plate's dimensions. Thin rectangular plates may fit between the phone and a roomy case, but textured or tightly fitted cases may not close evenly. Compare the plate thickness and footprint with the case interior, and avoid forcing the case closed around the installed plate.
How do I remove a plate without damaging the case?
Remove the phone from the magnetic mount and peel the plate away slowly at a shallow angle rather than pulling it sharply. If adhesive remains, clean the surface according to the case manufacturer's guidance. Some products claim residue-free removal, but results can vary with the case material, how long the plate was installed, and environmental exposure.
Can one metal plate work with different magnetic mounts?
A universal plate may work with multiple magnetic mounts, but the magnet's size and shape still determine how well it contacts the plate. A broad rectangle often suits a cradle, while a round disc may work better with a compact circular magnet. The device also needs enough surface area to remain balanced and secure.
How long should I wait after applying the plate?
The supplied Scosche instructions recommend waiting 24 hours before using its plates with a magnetic mount. Other products do not state a specific waiting period, but allowing time for the adhesive to settle is still sensible. Avoid pressing or loading the plate immediately after installation.
What should I do if a magnetic mount keeps slipping?
First check that the plate is flat, clean, and fully bonded to the device or case. Inspect the plate edge for lifting and confirm that the mount's magnet is contacting the broad face of the plate. If the adhesive has been contaminated or stressed, install a fresh plate and allow it to settle before use.
Final Thoughts on Choosing the Best Adhesive Metal Plates for Phone Mounts
The DSTELIN Universal 8 Pack is the most balanced budget-oriented option, offering four rectangles and four round plates with straightforward adhesive installation. The Scosche MagicMount Replacement Kit is the editor's choice for car use because of its automotive-grade adhesive, large plates, included cleaning supplies, and documented temperature considerations. The SALEX 16 Pack stands out for users who want a generous, thin replacement inventory with 3M adhesive backing.
Prioritize the shape and size of the mount's magnetic face, the dimensions of your phone or case, and the need for multiple spares. Also decide where the plate will sit relative to the wireless charging coil before applying it. For frequently used vehicle mounts, a documented automotive adhesive and a plate large enough for solid contact deserve extra attention.
Product ratings, availability, and prices can change over time, so review the current listing and confirm the included quantity, dimensions, adhesive instructions, and charging guidance before ordering. Those final checks will help ensure that the selected plates work with the mount, device, and installation location you actually use.
