Mount Ulanzi SK-23 electronic suction phone holder with 1/4" thread (model SB10665)

Ulanzi SK-23 electronic suction phone holder is a compact mounting solution that secures smartphones to smooth surfaces using an electronic suction mechanism. Designed for mobile filming, streaming, timelapse and hands-free phone positioning, the holder includes a standard 1/4" threaded attachment point that allows integration with tripods, articulating arms, camera rigs and other accessories. The device is intended to provide a stable platform for a phone while enabling quick attachment and release on glass, metal and other non-porous surfaces.

Advantages

The electronic suction control delivers consistent suction force without manual pumps, reducing setup time and ensuring repeatable attachment strength. A built-in 1/4" mounting thread enables direct connection to many tripods and arms, simplifying integration into existing camera or streaming setups. The holder’s compact footprint and secure clamping mechanism keep the phone steady for filming, time-lapse sequences and live streaming, while preserving access to charging ports and camera lenses on most phone models.

Suitable for

• Mobile filming and vlogging on windows, cars or smooth surfaces
• Live streaming and video calls where stable, hands-free positioning is required
• Timelapse photography using a fixed, non-porous mounting surface
• Integration with tripods, articulating arms or rig systems via 1/4" thread

How to use

Place the suction pad against a clean, smooth surface and activate the electronic suction control according to the product’s power method. Adjust the phone clamp to fit the device securely and orient the phone in portrait or landscape as needed. Use the 1/4" threaded point to mount the holder on a tripod or arm when additional height or articulation is required. To remove, deactivate the suction control and gently lift the release tab or edge of the pad to break the seal before detaching the phone.

Usage recommendations

For reliable adhesion, ensure the mounting surface is clean, dry and free from dust or oils. Avoid porous, textured or uneven surfaces. Check that the phone is securely clamped and balanced before use, especially when mounted on moving platforms such as vehicle windows. Follow the manufacturer’s instructions for powering the electronic suction system and observe any weight limits for safe operation.
