Supercage - Mobile Cage with Integrated USB-C Hub

Moment SuperCage — pro gear for a video-production side career

The gist: A modular phone rig with a built-in USB-C hub, aimed at remote professionals turning phone filmmaking into an income stream — course creation, freelance video, or a serious YouTube channel.

• Six accessories, one hub: Connects an external mic, headphone monitoring, a full-size SD card, HDMI output, and power through the cage base — no more juggling separate dongles for a client shoot.
• Modular NATO rail system: Continuous rails and an Arca-compatible base let you build out a rig with lights, a boom mic, or a monitor as a client project scales.
• Durable build: Reviewers found the materials solid and the phone mount extremely secure, important for gear you're relying on for paid work.
• On-location backup: The full-size SD slot lets you offload footage in the field without hauling a laptop to a shoot.

AppleInsider's review called the SuperCage the ultimate iPhone filmmaking accessory for build quality, though it flagged the bundled USB-C cable as stiff enough to complicate cable routing.

Best for: Remote professionals building a video production or content-creation income stream who need a reliable, expandable rig. Skip it if: you only record occasional webinars — a simple tripod and mic will do at a fraction of the cost. Runs ~$199 — check the current price before buying.
