Quad Lock is a two-part system: a case on your phone and a mount on your car, handlebar, desk or boat. The case clicks into the mount with a twist and locks, so the phone stays put over bumps. The newer MAG line adds magnets for easier alignment and works with MagSafe-style wireless charging.
The case is the part people get wrong. It has to match your exact phone model, and it's what you'll use every day, so start there.
Step 1: get the exact case for your phone
Quad Lock MAG cases are model-specific. The iPhone 13 and iPhone 13 Pro, for example, are close in size but have different camera bumps, so their cases are not interchangeable. The same goes for Pro vs Pro Max vs Plus, and for Galaxy S24 vs S24 Plus vs S24 FE.
- Check your model in Settings, then About (iPhone: Settings, General, About).
- Pick the case that names your exact model: 12/12 Pro, 13, 13 Pro, 14, 15, 16 and 17 families, Galaxy S23 FE, S24 Plus, S24 FE, and Pixel 9, 9 Pro and 9 Pro XL are all listed below.
- If your phone isn't listed, or you want to keep your own case, the MAG Universal Adaptor sticks to the back of almost any phone or case and makes it work with Quad Lock MAG mounts.
Step 2: pick a mount and add charging
Pair the case with the mount for where you'll use it: car dash, vent or windshield; motorcycle or bicycle handlebar; or a desk or wall. Quad Lock states that its MAG cases also work with its standard (non-MAG) mounts, so an older mount you already own will usually still fit.
For charging on the go, the MAG Wireless Charging Head replaces a standard mount head so the phone charges while it's locked in. In the car, the Quad Lock Wireless CarPlay Adaptor turns wired Apple CarPlay into wireless, a nice pairing if you want to drop the cable entirely.
Motorcycles: protect your camera
High-frequency vibration from motorcycle engines, especially high-power engines, can damage the optical image stabilization in modern phone cameras. Apple publishes a support note about this. If you ride, use a vibration dampener between the mount and the handlebar, and avoid mounting directly to the bars of high-power bikes. Bicycles and cars are not a concern.
Other mounts worth knowing
- Boats: Scanstrut ROKK Mini mounts are built for marine use with rail or screw-down bases. Scotty's post-mount holder is a favorite on fishing boats and kayaks.
- Magnetic car mounts: Scosche MagicMount and Mob Armor MobNetic use strong magnets for one-hand placement. Some models charge too.
- Waterproof holders: for pool, lake and beach days when splash protection matters more than a hard lock.
