Magnetic dashboard car holder Joyroom JR-ZS311 (grey) for smartphones

Joyroom JR-ZS311 is a magnetic dashboard car holder in grey designed to secure smartphones in a vehicle. The compact mount attaches to the dashboard using a 3M nano adhesive base and holds devices with a magnetic plate system. The holder features a rotating head for adjustable viewing angles and is made of ABS+PC materials. It is compatible with a wide range of phones from approximately 4 to 7 inches and includes metal plates and accessories for devices without built-in magnetic alignment.

Advantages

The JR-ZS311 offers strong neodymium magnets that provide stable support for smartphones and can hold heavier devices when the metal plate is correctly positioned. Its low-profile magnetic base minimizes visual obstruction while keeping the device accessible. The included accessories — metal phone bases, protective covers and cleaning kit — allow fast installation and secure mounting on different dashboards without permanent modification. The 360° rotating head enables flexible portrait or landscape orientation for navigation, calls and media.

Suitable for

• Hands-free navigation and GPS use while driving
• Making and receiving calls safely
• Viewing media or following maps in portrait or landscape
• Vehicles where a compact, non-permanent mount is required
• Phones without MagSafe when using the supplied metal plates

How to use

Clean the intended dashboard surface with the supplied cleaning kit and wait until it is dry. Remove the protective film from the 3M nano adhesive base and press the holder firmly onto the dashboard for several seconds to ensure a secure bond. Attach the appropriate metal plate to your phone or inside the phone case following the supplied instructions, then place the phone onto the magnetic base. Adjust the angle using the rotating head to the desired portrait or landscape position. To remove or reposition, gently peel the base away from the dashboard according to the adhesive manufacturer’s guidance.

Usage recommendations

For best performance, place the metal plate centrally on the phone or case and avoid placing magnetic plates over wireless charging coils. Regularly check the adhesive bond and clean contact surfaces to maintain stability. Do not rely on the mount to secure a phone during sudden heavy impacts; remove the device if safe handling is compromised.
