Designed for in-car phone mounting
The C221 is designed for vehicles with circular or round air vents — the rotatable clamp adjusts to fit inner diameters between 40mm and 70mm, with a minimum vent depth of greater than 34mm. The high-tenacity PC clamp is lined with silicone padding on all contact surfaces to protect the vent from scratching or deformation during clamping. The 10×2 N52 magnet array provides strong magnetic phone attachment. For MagSafe-compatible iPhones (12–16 series), the phone attaches directly via the magnetic array. A magnetic ring sticker is included in the box for use with phones that are not MagSafe-compatible — apply the sticker inside the case or between case and phone to enable magnetic attachment. The mount is not stated as Apple MFi certified in source documentation. No certifications listed. Curated by Aetheo for in-car phone mounting.
Key features
Circular vent compatibility — 40–70mm inner diameter, greater than 34mm depth
The C221 clamp is designed for circular or round air vents specifically — it is not designed for standard rectangular or blade-style vents. The rotatable adjustment mechanism sets the clamp to the vent's inner diameter between 40mm and 70mm. The vent must also be greater than 34mm deep for the clamp to seat securely. Verify your vent's shape, inner diameter and depth before purchase. Specific vehicle model compatibility examples are listed in the source, including certain Mercedes-Benz, BAIC, Jeep, Ford and Honda models — this is not an exhaustive list; verify fit with your vent profile.
N52 10×2 magnet array — MagSafe-compatible design
The holder face uses a 10×2 N52 magnet array. For MagSafe-compatible iPhones (iPhone 12–16 series), the phone's built-in MagSafe magnet ring aligns with the C221's magnet array for direct magnetic attachment. The C221 is described as MagSafe-compatible in design — it is not stated as Apple MFi certified or Apple-licensed in source documentation. The magnetic attachment enables portrait and landscape orientations.
Magnetic ring sticker included — for non-MagSafe phones
A black ring-shaped magnetic sticker is included for use with phones that do not have a built-in MagSafe magnet ring (Android phones, older iPhones). The sticker is applied inside the phone case or between case and phone — it enables magnetic attachment to the C221's magnet array. The sticker does not affect wireless charging compatibility; verify with your specific case and phone before applying.
PC and silicone construction — rotatable clamp
The clamp body is high-tenacity polycarbonate (PC) for rigidity and resistance to breakage. Silicone padding on the contact surfaces protects the vent from scratching or pressure damage during clamping. The rotatable adjustment ring is turned to set the clamp diameter to match the vent opening. Once tightened, the clamp holds the vent securely under vibration.
Best for
- Vehicles with circular air vents — inner diameter 40–70mm, depth greater than 34mm
- MagSafe-compatible iPhone 12–16 users who want magnetic in-car mounting
- Non-MagSafe phone users — magnetic ring sticker included for broad compatibility
- A clean, cable-free in-car phone mount without blocking the display
- Vehicles such as certain Mercedes-Benz, BAIC, Jeep, Honda and other models with circular vents
