Ulanzi phone suction mount SB9881 — MagSafe-compatible glass suction holder for smartphones

Ulanzi SB9881 is a suction cup phone mount designed for secure attachment of MagSafe-compatible smartphones to glass and other smooth surfaces. The mount uses a vacuum-based suction system to hold the phone in place on windows, mirrors or other flat glass panels. It is intended for hands-free filming, navigation, video calls and similar everyday tasks where a stable, compact holder is required.

Advantages

The SB9881 provides a stable, low-profile connection between a MagSafe-capable phone and a glass surface without requiring permanent fittings. Its vacuum suction mechanism creates a reliable grip on smooth glass while the MagSafe-compatible interface keeps the phone aligned and easily attachable. The compact design minimizes obstruction of the view through a window and allows quick repositioning or removal when not in use.

Suitable for

• Hands-free navigation in a vehicle with a glass windshield or passenger window
• In-car or home video calls where the phone must be mounted on a window or mirror
• Filming or time-lapse recording using a window as a mounting point
• Temporary mounting on glass surfaces for monitoring or reference viewing

Key specifications

• Mounting method: vacuum suction cup for smooth glass surfaces
• Compatibility: designed for MagSafe-capable smartphones and accessories
• Attachment orientation: supports vertical and horizontal placement depending on phone alignment
• Material: durable plastic and rubber components for suction sealing and phone interface
• Design: compact, low-profile holder suitable for windows and mirrors

How to use

Clean the glass surface to remove dust, oil or moisture before positioning the suction mount. Align the suction cup on the desired smooth glass area and press firmly to expel air, then engage the vacuum lock if the model includes a locking mechanism. Attach a MagSafe-compatible smartphone by aligning the phone’s magnetic interface with the holder until it snaps into place. Verify secure contact before driving or recording and remove the phone by pulling it away from the magnetic interface and releasing the vacuum lock to detach the suction cup.

Usage recommendations

For optimal performance, use the mount on flat, clean glass surfaces and avoid textured, curved or treated glass that may reduce suction strength. Regularly check the suction and magnetic contact before use, and avoid exposing the holder to extreme heat or direct prolonged sunlight which can affect suction performance.
