SmallRig Mobile Video Cage for iPhone 17 Pro Max Flagship Edition 5543

Professional Mobile Video Cage

The SmallRig 5543 is a flagship expansion cage built specifically for the iPhone 17 Pro Max. It combines a protective phone case, an aluminum alloy cage frame, and a TPU bumper into a single kit for professional video recording, live streaming, and short film production. The cage weighs 7.2 oz and uses lightweight PC, TPU, and aluminum alloy materials. It is designed for mobile creators who need a robust platform to mount accessories like handles, microphones, and lights while keeping the phone fully operational.

Thermals Noise and Power Access

The open, hollowed-out frame design allows unrestricted airflow around the iPhone 17 Pro Max during extended recording sessions, helping to manage device temperature passively. Because the cage adds no active electronics, fans, or power draw, it introduces zero noise and does not affect the phone's battery consumption. Full access to the charging port is maintained, so users can connect external power banks or wall adapters for continuous operation without removing the device from the rig.

Upgrade Path and Limitations

This cage replaces makeshift mounting solutions such as adhesive cold shoes or universal clamp rigs by providing integrated 1/4"-20 anti-twist threads, cold shoes, and quick-release interfaces for secure, wobble-free accessory attachment. It upgrades basic phone cases by adding a T-mount backplate and a 17mm threaded lens backplate, with optional 67mm magnetic filter support available separately. It is not suited for users who require a waterproof housing, a built-in battery pack, or a cage compatible with other phone models.
