Magnetic mount hold: Pixel 8 Pro on hollow aluminum treadmill consoles

Part of our guide on phone mount for 2 inch squat rack tube

Learn what to check, what to buy, and how to install a magnetic mount that actually holds a Pixel 8 Pro on a hollow aluminum treadmill console—without damaging your phone or the treadmill.

How hollow aluminum consoles change the magnetic picture (consolidated explanation)

Aluminum is non-ferrous, so it does not become magnetized by a magnet the way steel does. In a hollow aluminum console that means there is no underlying ferrous backing for the magnetic field to anchor to; additionally, the air gap created by a hollow cavity increases the distance and path the magnetic field must cross to reach anything ferrous (like an added metal plate). The result is an effective reduction in the magnetic coupling compared with mounting on steel or iron-backed surfaces.

This is not a single fixed percentage reduction in hold strength that applies in every case. The effective loss depends on console wall thickness, how deep the hollow cavity is, any internal bracing or components that might be ferrous, and how the mount and plate make contact. Because manufacturers publish holding force ratings measured on steel or flat ferrous plates, you must treat any 'hollow aluminum' number as an estimate derived from those steel ratings and from user reports and practical tests.

Put simply: don’t assume a mount rated for a certain force on steel will deliver the same force on a hollow aluminum treadmill console. Use that steel rating to calculate a margin—pick a mount with a higher steel rating to compensate for expected loss—and verify in-place before running at high speed.

What holding-force numbers mean and how to treat them

Manufacturers typically quote holding force measured against a flat steel plate. When you see a number like '3 kgf' or '4 kgf', that is the measured attraction to ferrous material in ideal conditions. Because hollow aluminum is not ferrous and often increases distance, treat these published numbers as the starting point, not the final answer. The other half of this decision is charging and holding on treadmill consoles.

For practical selection, a common approach used by experienced users and reviewers is to target a mount with a steel-surface rating high enough to leave a safety margin after accounting for case thickness, treadmill vibration, and expected movement. A recommended steel-surface rating range for Pixel 8 Pro on hollow aluminum consoles is roughly 3–5 kgf—higher for thicker cases or more vigorous running. This range is an evidence-informed estimate based on manufacturer specs (steel tests) and aggregated user experience; it is not a guaranteed performance figure on every console.

If you want to be conservative, choose a mount toward the upper end of that range and verify the hold in a controlled test (walk and jog at the speeds you use) before relying on it in regular workouts.

Case, plate, and charging considerations (condensed)

Phone weight, case thickness, and where you place a metal plate matter. The Pixel 8 Pro weighs about 213 g (per Google product specifications). A thin plastic or silicone case (around 2 mm or less) transfers magnetic force with much less attenuation than thick rugged or metal-backed cases. If you use a metal plate, placing it inside the case (between case and phone back) concentrates the magnetic connection while keeping the plate from scratching the phone and preserving the case appearance. It helps to understand treadmill console phone mount issues before going further.

Wireless charging and sensors: many phones (including the Pixel line) have a wireless charging coil and sensors located on the phone’s back. Placing a metal plate directly over the charging coil can block or reduce wireless charging and may interfere with back-mounted sensors. To avoid this, place the plate off-center or use a plate specifically designed to allow wireless charging. If you want the greatest safety and minimal interference, use a thin plate inside the case and test wireless charging afterwards.

Warranty and device safety: attaching adhesive plates inside a removable case is generally low-risk for the phone and less likely to void warranties. Gluing metal plates directly to the phone’s back or making permanent alterations to the phone or its original case could violate warranty terms or damage finishes. Always check your phone and treadmill warranties and the terms from the case manufacturer before applying permanent adhesives.

• Pixel 8 Pro weight: ≈ 213 g (Google specs).
• Prefer plates inside a removable case to avoid direct adhesive on the phone.
• Avoid placing plates over charging coils; choose plate placement to preserve wireless charging.

Practical mount and plate recommendations (specific examples)

Below are example products and product types that meet the criteria discussed. I list them as examples—verify the vendor’s published holding test method and steel-surface rating and test the final setup on your treadmill before regular use. We cover picking magnetic holders for heavy phones in its own article.

1) Pitaka MagEZ Mounts (example: Pitaka MagEZ Car Mount or MagEZ Magnetic Dashboard Mount). Pitaka’s MagEZ line uses multiple neodymium magnets and is designed to work with a corresponding thin MagEz plate or magnetic case. These mounts are commonly reported by users to provide strong hold for heavier phones when paired with the recommended plate. Check the product’s listed steel-surface holding force and customer reviews for treadmill use.

2) Spigen Mag Fit / Spigen Magnetic Mount Kits. Spigen sells small plates and mounts that pair with cases; their hardware is widely available and designed to be thin enough to allow charging in many configurations. Spigen’s product pages usually include compatibility notes and usage guidance; look for models that offer multi-magnet arrays.

3) Mechanical or hybrid options: iOttie and Nite Ize Steelie solutions. If you prefer a backup or a mechanical clamp, consider a hybrid mount that uses magnetic holding plus a mechanical cradle or clamp (for example, iOttie’s Easy One Touch is a mechanical solution; Nite Ize Steelie uses a ball and socket combined with plates). These reduce reliance on pure magnetism on non-ferrous surfaces. People in this spot often ask about magnetic pouch for treadmill frame phone as well.

When selecting, look for mounts that either (a) include a thin adhesive metal plate intended for placement inside a case, or (b) explicitly state compatibility with aftermarket thin plates. Avoid mounts that depend entirely on adhesive bonding to the console itself for primary security.

Installation and damage/warranty warnings (important)

Do not glue metal plates or strong adhesives directly to the treadmill console without checking the treadmill manufacturer’s guidance. Adhesives can remove paint or surface coatings, leave residue, or cause long-term cosmetic or structural damage—particularly on thin aluminum skins. If you need a more secure attachment to the console itself, prefer non-destructive methods such as clamp-on mounts, straps, or pads that use friction rather than permanent adhesives.

For the phone and case: placing an adhesive plate inside a removable case is the safest way to avoid direct phone modification. Placing a plate directly on the phone’s outer surface can trap debris under the plate, scratch finishes, block wireless charging, and may violate the device warranty depending on the manufacturer’s terms. Check Google’s Pixel warranty and the case maker’s guidance if you are unsure.

If you choose to use adhesive metal plates, follow these safe-install practices: clean the case interior before applying, place the plate away from wireless charging coil and camera module, press firmly and allow the adhesive to cure per manufacturer instructions, and keep proof of purchase and any removal instructions in case you need to return the phone or case.

Final checklist before you run

1) Confirm Pixel 8 Pro weight from your device docs (≈ 213 g) and the case weight you will use.

2) Choose a mount with a steel-surface holding rating in the 3–5 kgf range (estimate) or higher for rugged cases and stronger running.

3) Use a thin metal plate inside your removable case when mounting to a hollow aluminum console; avoid sticking metal directly to the phone or console if you want minimal risk to finishes or warranty.

4) Test mount security at walking speed, then jogging speed, before trusting it at full workout intensity.

5) Prefer clamps, straps, or hybrid mechanical mounts if your console is extremely thin or has large cavities.

Questions people still ask

Recommendations are based on published manufacturer holding ratings (measured on steel), industry practices for magnetic mounts, and aggregated user experience. Exact performance on hollow aluminum consoles varies; test in place.
