A metal plate for magnetic mount is a thin steel or iron attachment that gives a phone, tablet, or GPS device a firm connection point for a magnetic holder. The right plate should fit discreetly inside a case, bond reliably to a smooth surface, and provide enough metal area for the mount’s magnet to grip without adding unnecessary bulk.

We compared all ten products by examining pack quantity, plate shape and dimensions, stated thickness, adhesive system, mounting scenarios, and device compatibility. The list covers small four-piece kits, large multi-plate sets, round discs, narrow strips, and square sheets for car vents, dashboards, walls, and other magnetic accessories.

Each review highlights the feature that makes a particular option most useful, while also noting relevant limitations such as MagSafe incompatibility, case bulk, or the need to position a plate carefully. Ratings reflect the supplied customer feedback, and current prices can change, so shoppers should confirm the latest listing before purchasing.

1. WixGear X4 Metal Plate Set – Best Overall Flexibility

Mount Metal Plate with Adhesive for Magnetic Cradle-Less Mount by WixGear - X4 Pack 2 Rectangle and 2 Round (Compatible with Magnetic mounts) (Black)4.6Editor scoreCheck price on Amazon
WixGear X4 Metal Plate Set
Four-piece mixed-shape set
Two rectangles, two round
Strong adhesive backing
Universal device compatibility

The WixGear X4 is a compact four-piece set with a 4.6 customer rating, combining two rectangular plates with two round ones. That mixed-shape format is unusually versatile for a small kit because it can suit magnetic cradles designed for either a broad plate or a circular attachment point. The plates are intended to work with magnets for phones, cases, and other compatible devices.

Pros

  • Mixed shapes support varied mounts
  • Compact enough for phone cases
  • Easy peel-and-stick installation
  • Works across multiple device types

Cons

  • Only four plates included
  • Wireless charging may be affected

Its main strength is installation flexibility. Each plate carries adhesive backing that can be applied directly to a phone or case, or positioned between the device and case for a more discreet appearance. The broad compatibility claim covers phones and cases using magnetic mounting systems, while the rectangular and round options let users select a geometry that better matches the magnet they already own.

The principal limitation is the small quantity. Four plates are enough to replace or configure a few devices, but shoppers with several phones, tablets, or frequently changing mounts may prefer a multi-pack. Placement also matters: a plate installed over a phone's wireless charging area can interrupt that function, so the case or an appropriate section of the device should be chosen carefully.

This is a strong budget-oriented choice for a first magnetic mount, a mixed collection of devices, or a replacement kit covering both round and rectangular magnet designs. It offers the core functionality without unrelated components, making it a practical entry point for users who want simple adhesive metal mounting plates.

Two Shapes Expand Mount Compatibility

Including both round and rectangular plates reduces guesswork when the dimensions of a magnetic cradle are unknown. A broad rectangle can support a larger contact area, while the round discs can be more appropriate for circular magnetic attachment points or devices with limited flat space.

A Discreet Placement Option

Because the adhesive plates can sit between a phone and its case, users can often conceal the metal while preserving the magnetic connection. Directly attaching a plate to the outside of a case is another option when the mount requires a clearly accessible surface.

2. 24-Pack Rectangular Steel Plates – Best for Multi-Device Setups

24 Pack Adhesive Metal Plates for Magnetic Mount, 2.3x1.1in Metal Strips for Magnets, Rectangular Steel Sheets for Non-Steel Vents (0.02 in)4.6Editor scoreCheck price on Amazon
24-Pack Rectangular Steel Plates
Twenty-four iron plates
2.3 by 1.1 inches
0.02-inch sheet thickness
Works on non-steel vents

This 24-pack of 2.3 by 1.1-inch rectangular iron plates carries a 4.6 customer rating and is built for users who need more than one magnetic attachment point. Each plate is only 0.02 inch thick, allowing it to fit discreetly inside a phone case without creating the pronounced bulge associated with thicker metal accessories.

Pros

  • Generous 24-piece quantity
  • Slim profile fits inside cases
  • Useful for non-steel vents
  • Supports phones, tablets, GPS

Cons

  • Rectangular shape only
  • Avoid placing over charging area

The set is particularly useful for magnetic car mounts, wall mounts, and phone holders because it provides ample spare plates for several devices or for replacing pieces that have been exposed to heat and wear. Its adhesive backing is described as strong and removable without sticky residue, giving users flexibility when changing devices or cases.

Another notable application is a non-steel vent. Aluminum and plastic vent structures cannot provide the same magnetic attraction as steel, so adding a small iron plate can create a suitable connection surface. The stated versatility also extends to tablets and GPS devices, although the plate still needs a clean, smooth bonding area and the target magnetic accessory must be compatible.

This is the most practical selection for a household, work fleet, or collection of devices that regularly uses magnetic mounts. The large quantity, slim profile, and useful rectangular shape outweigh the lack of round discs. Buyers should still confirm the mount geometry and keep the plate away from a wireless charging coil if charging and magnetic holding are needed simultaneously.

A Spare Plate for Every Setup

Twenty-four plates make it easy to prepare several phones, tablets, or GPS devices without repeatedly reusing a single adhesive piece. Spare plates are also helpful for replacing one that has accumulated debris or lost adhesion after prolonged use.

Slim Enough for Everyday Cases

At 0.02 inch thick, these iron sheets can be hidden between a device and its case. That keeps the magnetic surface available while minimizing the extra depth that users may notice in their pocket or when handling the device.

3. SALEX 16-Pack Black Plates – Best Discreet Car-Mount Upgrade

SALEX Replacement Metal Plates Set 16 Pack for Magnetic Car Mount. Kit of 16 Magnets for Back of Phone Case. Black Rectangular Iron Stickers Without Holes Discs. 3M Adhesive Backing Steel Sheets.4.5Editor scoreCheck price on Amazon
SALEX 16-Pack Black Plates
Sixteen black steel plates
2.56 by 1.77 inches
0.02-inch sheet thickness
3M adhesive backing

The SALEX set includes 16 black rectangular steel plates and has a 4.5 customer rating. Each plate measures 2.56 by 1.77 inches, or 65 by 45 millimeters, and has a stated thickness of 0.02 inch, or 0.5 millimeters. The low-profile construction is intended to sit between a phone and its case rather than project noticeably from the back.

Pros

  • Large 16-piece replacement set
  • Black finish blends with cases
  • Hides easily inside cases
  • Supports many device brands

Cons

  • Not magnetic by themselves
  • Some wireless charging interference

We may earn a commission when you buy through this link, at no additional cost to you.

Its 3M adhesive backing is the defining installation feature. The plates can be attached to a phone, tablet, GPS unit, rugged case, or battery cover, allowing a magnetic car, wall, or case mount to pull against the added metal surface. The black finish also makes external placement less conspicuous, although hiding the plate inside a compatible case remains the cleanest visual result.

The product title and description use the word magnets loosely, but the actual components are iron or steel plates without built-in magnetism. They work only when paired with a genuine magnetic mount. Buyers should also note that an adhesive plate covering a wireless charging region can interfere with charging, so placement needs to account for the device's charging layout.

This kit is well suited to drivers who want replacement plates in black, use a magnetic cradle regularly, and prefer a larger rectangular contact area. It balances quantity, low thickness, and a broad device list, making it a strong choice for a car-focused magnetic mount installation.

A Low-Profile Plate for Cases

The 0.02-inch steel sheet is slim enough to hide between a phone and a compatible case. This preserves magnetic attraction without producing the deep rectangular block that some thicker accessories create.

Black Discreet Appearance

A matte-looking black surface can blend more naturally with many black cases than a bright silver plate. If the plate must remain outside the case, its dark finish also reduces visual distraction.

Four-Piece Rectangle and Round Set
Four black metal plates
Two rectangular, two round
Rectangles measure 4.5 by 6.5cm

This four-piece black metal plate set is a straightforward option for adding a magnetic connection point to a phone or case. It has a 4.5 customer rating and includes two rectangular plates measuring 4.5 by 6.5 centimeters and two round plates with a 4-centimeter diameter. The mixed format gives buyers more choice than a kit containing only one shape.

Pros

  • Useful mixed-shape selection
  • Large rectangular plate area
  • Simple adhesive installation
  • Suitable for phone cases

Cons

  • Only four pieces included
  • May interfere with wireless charging

The adhesive allows a plate to be attached directly to the back of a phone or positioned between the phone and its case. Once the plate is bonded, a compatible magnetic mount can attract the metal and hold the device in place. The relatively large rectangles may offer a useful contact area, while the round plates can fit holders designed for circular metal discs.

There are two important limitations. First, the plates contain no magnets, so they do nothing on their own and must be used with a magnetic holder. Second, the listing explicitly warns that placing a plate on the back of a phone may disable wireless charging, particularly if it covers the charging coil.

This set is best for users who need only a few replacements and want both rectangle and round formats. It is particularly appropriate for a compatible phone case, a magnetic car cradle, or a holder whose magnet has a circular attachment area. The small count limits its value for large multi-device fleets, but the shape variety makes it convenient for occasional use.

Match the Plate to the Magnet

The circular discs are useful when a holder expects a disc-shaped steel target, while the larger rectangles suit mounts designed around a broad flat surface. Matching the shape improves the chance of balanced contact between the mount's magnet and the plate.

Protect Charging Compatibility

Because the plate can interfere with wireless charging, place it where the charging coil is not positioned. A compatible case interior or a non-charging section of the device may provide a better bonding surface.

Scosche Large Plate Kit
Two large black plates
Automotive-grade adhesive
Protective film and wipes
Three-year limited warranty

The Scosche MagicMount large plate kit has a 4.6 customer rating and is designed around secure attachment for larger phones. Its two large, black metal plates use automotive-grade adhesive, creating a substantial magnetic connection point for compatible car or home phone holders. The plates are not magnets themselves; they provide the iron surface that a magnetic mount can attract.

Pros

  • Large plate supports firm attachment
  • Adhesive designed for temperature changes
  • Protective film reduces residue risk
  • Includes cleaning supplies

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.

Temperature resistance is an important strength. The product information specifically describes the adhesive as suitable for heat, cold, and daily use, which makes the kit relevant to dashboard and windshield environments where ordinary household adhesive may perform less predictably. Cleaning wipes and a protective film are included, giving users the tools needed to prepare the bonding surface and reduce the possibility of residue or surface damage.

The instruction to place the plate directly on the phone or outside the case reflects an important practical point. A plate hidden under a thick or textured case may not sit close enough to the mount's magnet for a strong hold. The product is also explicitly not compatible with MagSafe, so buyers already relying on MagSafe do not need a conventional replacement plate.

This premium kit is best for drivers with larger phones who want a large, dedicated metal target and a carefully supported installation. The two-piece count is modest, but the included preparation materials, large contact area, and automotive-oriented adhesive make it a refined choice for a single primary device or a small two-device setup.

Prepared Surface Improves Adhesion

The included cleaning wipes help remove oils and residue before the plate is pressed into position. The protective film can create a smoother barrier between the adhesive and the device or case, supporting cleaner removal later.

A Larger Target for Larger Phones

A broad plate gives the magnet more surface to engage, which can be valuable with a heavier device. Positioning the plate on the outside of the case also reduces the gap that would otherwise weaken the magnetic connection.

6. GradCap Ultra-Thin Discs – Best Minimal-Profile Disc Option

GradCap Magnetic Phone Mount Metal Plates, 4 Packs Ultra Thin Metal Discs4.4Editor scoreCheck price on Amazon
GradCap Ultra-Thin Discs
Four circular manganese-steel discs
0.02-millimeter profile
3M double-sided adhesive
One-year warranty included

GradCap offers four ultra-thin metal discs designed for magnetic phone mounts, and the set carries a 4.4 customer rating. Each disc is made from manganese steel with a stated thickness of 0.02 millimeters, making this one of the slimmer configurations in the comparison and especially useful for users who dislike the bulge created by thicker plates.

Pros

  • Exceptionally thin construction
  • Four discs for multiple devices
  • Works across common mount types
  • Quick tool-free installation

Cons

  • Lower customer rating
  • Circular shape may not suit all mounts

We may earn a commission when you buy through this link, at no additional cost to you.

The discs use 3M double-sided tape to adhere to a phone or protective case. Once installed, they are compatible with magnetic air-vent, dashboard, and windshield holders as well as magnetic tripod stands used for recording, photography, and selfies. Installation is tool-free and is described as taking one to two minutes, which makes the product convenient for temporary or frequently changed setups.

The tradeoff is that every plate in the pack is circular, so it is not as adaptable to a mount designed for a rectangular target. The set also does not include magnets, and it is presented for non-MagSafe phones. Users should ensure that the disc lies flat and that the device's wireless charging area is not covered if they need to charge while using a magnetic setup.

This is a sensible choice for a car owner who values an almost invisible profile, uses a disc-compatible magnetic cradle, and wants four backups at once. It falls short of the highest-rated kits but stands out in thinness and quick installation. For a matching circular mount and minimal case bulk, it delivers a focused purpose.

Minimal Bulk for Car Use

The 0.02-millimeter discs can be tucked into a case with very little added depth. That is useful for drivers who frequently remove and replace a phone and do not want a thick metal target affecting the way the device sits in their hand.

Useful Beyond the Car

The same adhesive discs can support magnetic stands used for photography, recording, or everyday viewing. Their small round shape is particularly convenient when a device must be moved among several compatible stands.

7. 24-Pack Narrow Magnetic Strips – Best for Flexible Installations

24 Pack Adhesive Metal Plates for Magnets, Ultra-Thin Strips 2 x 0.96 Inch4.3Editor scoreCheck price on Amazon
24-Pack Narrow Magnetic Strips
Twenty-four iron strips
2 by 0.96 inches
0.02-inch profile
Adhesive and screw options

This 24-pack of 2 by 0.96-inch iron strips has a 4.3 customer rating and offers unusually broad installation flexibility. The strips are 0.02 inch thick, use a strong adhesive backing, and can be applied to smooth surfaces such as wood, plastic, glass, or walls. They are also useful with magnetic LED lights, phone mounts, and vent covers.

Pros

  • Narrow shape suits varied spaces
  • Twenty-four spare strips
  • Supports adhesive or screws
  • Works beyond phone mounts

Cons

  • Lowest rating in comparison
  • May interfere with wireless charging

We may earn a commission when you buy through this link, at no additional cost to you.

A defining feature is the choice between peel-and-stick and screw installation. Pre-drilled holes allow a strip to be secured with a screw when a more permanent mechanical attachment is preferred. That makes the plates useful beyond ordinary phone cases, particularly for fixed installations or surfaces where a user wants additional security beyond adhesive alone.

The narrow rectangular format is the main attraction and the main constraint. It can fit into confined areas where a larger plate would be awkward, but some magnetic mounts require a broad, flat target for reliable engagement. The listing also says the profile allows seamless wireless charging, while another listed use warns against placing a plate over a charging area; in practice, placement should still be selected with the device layout in mind.

This set is best for experimenters, installers, and owners of magnetic LED lighting or non-steel vent covers who want many inexpensive spares. It may be less suitable as a premium replacement plate for a single high-end phone mount, where a larger dedicated target and support-focused kit could be preferable.

More Than a Phone Accessory

The strips can create a magnetic target for compatible LED fixtures and vent covers as well as phones and GPS devices. This makes the 24-piece pack useful for home, workshop, and vehicle projects that require several small steel surfaces.

Choose the Right Installation Method

Adhesive is convenient for a removable setup, while the pre-drilled holes allow screws for a fixed surface. Users can select the method that best matches the location and how frequently they expect to move the device.

8. 24-Pack Square Steel Plates – Best Balanced Plate Shape

24-Pack Square Steel Plates
Twenty-four square iron plates
1.6 by 1.6 inches
0.02-inch sheet thickness
Non-steel vent compatible

The 24-pack of 1.6 by 1.6-inch square iron plates combines a 4.6 customer rating with a balanced shape that works well for many magnetic mounts. Each plate has a stated thickness of 0.02 inch, allowing it to sit discreetly inside a case while leaving enough flat metal for the mount's magnet to engage.

Pros

  • Balanced square contact area
  • Generous replacement quantity
  • Slim case-friendly profile
  • Strong adhesive backing

Cons

  • Square shape only
  • Requires a compatible square-friendly mount

We may earn a commission when you buy through this link, at no additional cost to you.

The square format is a useful middle ground between a large rectangle and a small disc. It offers a broad, even surface without the elongated outline of a strip, and the stated application for non-steel vents makes it especially relevant to cars with aluminum or plastic vent assemblies. The same adhesive-backed approach also supports wall mounts, phone holders, tablets, and GPS devices.

The plates are described as durable iron with adhesive that provides a firm bond and allows clean removal. As with every conventional replacement plate in this category, the plate itself is not magnetic, and it must be used with a holder that contains a magnet. The small square dimensions may also be less suitable for a holder designed around a much larger rectangular steel target.

This set is an excellent all-around choice when the exact plate shape of the mount is unknown or when a balance between compactness and contact area is wanted. The 24-piece count, 4.6 rating, and thin square design make it particularly practical for multi-device users and for adding magnetic attachment points to non-steel vent covers.

A Balanced Shape for Magnetic Contact

The square profile gives the magnet a flat, centered area to attract. It can be easier to align than a narrow strip and less cumbersome than a larger rectangular plate, making it a versatile middle option.

Useful for Non-Steel Vehicle Vents

Aluminum and plastic vent parts are not inherently magnetic. Bonding one of these iron plates to a clean vent surface gives a compatible magnetic accessory a place to attach while keeping the plate small enough for a crowded dashboard.

Scosche Universal Plate Kit
Large and small black plates
Automotive-grade adhesive
Protective film included
Limited three-year warranty

The Scosche MAGRKI MagicMount kit has a 4.6 customer rating and includes both large and small black metal plates. That size combination is one of its most useful distinctions, allowing a user to fit a smaller phone or a more compact device with the small plate while giving a larger phone a broader magnetic target. The kit also includes 3M adhesive, protective film, and a user manual.

Pros

  • Two plate sizes included
  • Supports large and small devices
  • Protective film supports clean removal
  • Strong for car and home mounts

Cons

  • Not compatible with MagSafe
  • Large plate may affect smaller cases

We may earn a commission when you buy through this link, at no additional cost to you.

The automotive-grade adhesive is intended to create a lasting connection in a vehicle, including hot and cold conditions. The large plate is positioned on the phone or outside its case to reduce the gap between the magnetic mount and the metal, while the small plate offers a more compact alternative. Placement directly on the outside of the case can also help when a case's material or thickness interferes with attraction.

The protective film is a thoughtful addition because it creates a smooth barrier between the adhesive and the device or case. According to the product information, this helps with removal without residue or damage. Buyers must still allow the adhesive to set for 24 hours before attaching the mount, and the product is explicitly not compatible with MagSafe.

This is a strong recommendation for anyone using more than one device size or needing a durable replacement plate for a car or home magnetic holder. The two-size arrangement is more versatile than a uniform pack, while the included protective materials and support make the installation process more considered than a basic adhesive-only kit.

Two Sizes for Different Devices

A small plate can be less conspicuous on a compact phone, while the large plate gives heavier or larger devices more surface area. Having both in one kit reduces the need to purchase separate replacement styles.

Allow the Adhesive to Set

The installation guidance calls for waiting 24 hours before using the mount. This gives the automotive-grade adhesive time to establish a stable bond and improves the likelihood of a consistent magnetic connection.

24-Pack Matte Black Plates
Twenty-four matte black plates
Rectangular steel profile
0.02-inch thickness
Car and wall mount use

This 24-pack of matte black rectangular steel plates has a 4.4 customer rating and focuses on providing many replacement targets in a subdued finish. The product title lists a 2.55 by 1.77-inch size, while the bullet information describes the plates as 2.88 by 1.77 inches. Buyers should therefore verify the exact dimensions shown on the live listing before ordering for a particularly tight case or narrow mounting area.

Pros

  • Large 24-piece quantity
  • Discreet matte black finish
  • Slim enough for inside cases
  • Works for phones and tablets

Cons

  • Only includes one shape
  • Dimension listing varies

The 0.02-inch thickness is the main functional feature. It allows the plate to fit inside most conventional phone cases without creating much additional volume, and the smooth edges are intended not to scratch the device or the user's fingers. The black matte finish offers a less conspicuous appearance than silver metal, especially on a dark case.

The adhesive backing is designed to hold firmly while permitting clean removal when needed. Plates can support magnetic car stands, wall-mounted holders, and phone stands, including uses on non-steel surfaces. The kit is also stated to be suitable for smartphones, tablets, and GPS devices, which broadens its value beyond a single phone mount.

This set is a practical choice for users who need many black replacement plates or want to prepare several devices at once. Its quantity and understated finish are strong advantages, although the lack of shape variety and inconsistent dimension wording make it less convenient for projects requiring a precisely known plate size.

A Discreet Black Surface

Matte black can blend with a dark case or a black phone more naturally than a bright silver plate. This is helpful when the plate must remain outside the case or be visible inside a transparent design.

Plenty of Replacements on Hand

Twenty-four plates are enough to cover several devices while keeping extras available for replacement. A large reserve is also useful for users who cycle among cars, desks, and home magnetic stands.

Buying Guide – How to Choose the Best Metal Plate for Magnetic Mount

Choosing a metal plate for magnetic mount requires balancing the holder's geometry, the device's case, the bonding surface, and the environment where the device will be used. The most important details are plate size, thickness, adhesive, and magnetic-system compatibility.

Confirm Magnetic Holder Compatibility

These products are generally iron or steel plates without built-in magnets, so they only work when paired with a holder that contains a genuine magnet. Some listings use the word magnet loosely, but a non-magnetic plate cannot attract another plate by itself. Check whether the holder accepts a round disc, a square sheet, or a broad rectangular target, and make sure the chosen plate creates enough overlap with the magnetic area.

Select the Right Plate Dimensions

Plate dimensions influence both magnetic engagement and case fit. A broad rectangle can support a larger or heavier device, while a compact disc may be easier to hide in a small case. Square plates offer a balanced contact area, and narrow strips can work in confined locations. Measure the available space between the device and case before ordering, and check the seller's stated dimensions carefully because one listing contains conflicting width information.

Consider Plate Thickness

Most options in this guide use an ultra-thin profile of approximately 0.02 inch, although one disc is listed at 0.02 millimeter. Thin plates are easier to conceal between a phone and its case and are less likely to interfere with handling. A slightly thicker plate may provide more rigid contact, but it can create a noticeable bulge. For a magnetic mount, keeping the metal close to the magnet is generally more important than adding substantial thickness.

Evaluate the Adhesive System

Look for adhesive described as 3M, automotive-grade, or designed for heat, cold, and daily use if the plate will be mounted in a vehicle. The surface should be clean, smooth, and free of oils before application. Some kits include cleaning wipes and protective film, while others provide only peel-and-stick plates. Adhesive performance also depends on the material underneath, so textured plastic, fabric, and heavily curved surfaces may bond less reliably.

Account for Wireless Charging

A metal plate can block the electromagnetic field used for wireless charging if it overlaps the charging coil. Some product descriptions claim compatibility, while others explicitly warn against covering the charging area. The safest approach is to place the plate in the case, on an appropriate section away from the coil, or on the outside of the case where charging hardware does not pass beneath it.

Choose the Appropriate Pack Size

A four-piece set is sufficient for a single phone, a couple of cases, or a mixed-shape replacement. Larger 16-piece and 24-piece packs are more useful for families, business devices, frequent replacement, or installing magnetic LED lights and vent covers. Quantity should be matched to the number of devices and mounting locations rather than treated as the only measure of quality.

Match the Plate to the Application

Car and home phone mounts are the most common uses, but some plates also suit magnetic LED lights, tripods, photography stands, GPS devices, tablets, and wall holders. Non-steel vent surfaces such as aluminum or plastic may require an added steel target. Consider whether the plate is intended to sit inside a case, outside it, or directly on another accessory, because each location affects adhesion and magnetic reach.

How to Use and Care for Your Metal Plate for Magnetic Mount

Begin by cleaning the selected bonding area with the included wipe or a suitable cleaner, then allow it to dry completely. Decide whether the plate will sit between the device and its case or attach to the outside. Remove the adhesive backing, align the plate, and press it firmly in a consistent position without touching the adhesive surface afterward.

Allow the adhesive to bond before using the magnetic mount. The Scosche installation guidance specifically recommends waiting 24 hours, and following a similar settling period is sensible for other sets as well. Keep the plate clear of dirt, lint, and fingerprints during installation because contamination can reduce adhesion and interfere with the smooth contact needed for magnetic attraction.

For ongoing care, inspect the plate periodically and clean both its surface and the corresponding area of the holder. Avoid bending the thin steel sheet, and do not drag the device across a hard mount surface, as the edge of the plate could scratch the device. When changing cases or devices, peel the plate away slowly and store it flat to help prevent warping. If wireless charging is needed, remove or relocate the plate to a position that does not cover the charging coil.

Frequently Asked Questions

Are these metal plates magnetic?

No. The plates in this guide are made from iron or steel but do not contain built-in magnets. They create a magnetic connection only when placed near the magnet in a compatible phone holder, car mount, wall mount, or other magnetic accessory. A plate cannot hold a device by itself.

Can I put a metal plate inside my phone case?

Yes, and it is a common way to conceal the metal while keeping it close to the device. Make sure the case is not excessively thick or textured, and verify that the plate is placed on a flat, clean area. It should also sit far enough from the wireless charging coil to avoid charging interference.

Will a metal plate stop wireless charging?

It can if the plate covers the wireless charging coil. The effect depends on the device, plate placement, and charging system, and the product descriptions give mixed guidance. For the safest result, place the plate inside the case but away from the coil, or use the outside of the case where the charging hardware is not located.

Are these replacement plates compatible with MagSafe?

Not in the conventional sense. The two Scosche kits explicitly state that they are not compatible with MagSafe, and the other products are standard adhesive iron or steel plates rather than a MagSafe accessory. A device with a built-in magnetic system can still use a conventional magnetic mount, but the plate will not reproduce MagSafe's alignment or accessory ecosystem.

What size metal plate should I choose for a car mount?

Choose a size that overlaps the mount's magnet and fits inside the available case space. Large rectangular plates suit many larger phones, square plates offer balanced coverage, and round discs work best with disc-compatible holders. Measure both the magnetic area and the case interior before ordering.

How long should I wait after attaching the plate?

Waiting 24 hours is the clearest guidance provided by the featured Scosche kits. Giving the adhesive a full day helps it establish a stable bond before repeated magnetic attachment or removal. Users can follow the instructions included with their specific product, especially when the plate will be exposed to heat or cold.

Can I use these plates on a non-steel car vent?

Yes. Several sets specifically identify aluminum and plastic non-steel vents as suitable applications. The iron or steel plate provides the magnetic target that the vent itself lacks, but the surface must be clean, smooth, and firmly bonded before attaching a magnetic vent cover or phone mount.

How do I remove a plate without leaving residue?

Peel the plate away slowly rather than pulling sharply, especially when it has been mounted for a long time. Kits that include a protective film can make removal cleaner because the film acts as a barrier between the adhesive and the device or case. If the plate is permanently installed, gently warming the adhesive may help, but avoid exposing the device to excessive heat.

Final Thoughts on Choosing the Best Metal Plate for Magnetic Mount

The WixGear X4 stands out for its balanced four-piece mix of round and rectangular plates, while the 24-pack rectangular and square iron sets provide excellent value for multi-device users. For a more refined installation, the Scosche large-plate and universal kits add strong adhesive, protective preparation materials, and support, with the universal kit offering both large and small plate sizes.

Prioritize compatibility with the existing magnetic holder, the available space inside the case, and the bonding surface. Match the plate shape and dimensions to the magnet, keep it away from the wireless charging coil when necessary, and allow the adhesive to set before putting the device into daily use. These details matter more than the number of pieces in the pack.

Customer ratings, product availability, and prices can change, so confirm the current listing and final specifications before buying. In particular, verify the dimensions of the matte black 24-pack because its title and bullet points list different widths. Checking the live product page can also reveal updated package contents, compatibility notes, and installation instructions.
