Moment’s SuperCage offers a comprehensive upgrade for phone videographers by integrating a full USB-C hub into a rugged aluminium cage, enabling simultaneous power, storage, and external monitor connections , but at a premium price.
Moment’s SuperCage is a more ambitious answer to mobile video than the usual phone frame. Rather than acting as a simple shell with mounting points, it builds a USB-C hub into the rig itself, turning a compatible handset into something much closer to a compact production tool. The company says the design is aimed at users who need power, external storage, monitoring and audio connections at the same time, a requirement that quickly exposes the limits of a phone’s single port.
According to Moment, the cage routes the phone through a custom ribbon cable into a hub mounted in the base of the frame. That hub provides 100W USB-C power delivery pass-through, a 10Gb/s USB-C 3.2 connection for external storage, a full-size SD 4.0 card slot, HDMI output at up to 4K60, separate 3.5mm microphone and headphone jacks, and an additional USB-C port. In practice, that means a user can record to an SSD, monitor on an external display, listen through headphones and keep the phone charged at the same time.
The hardware itself is built around an aluminium cage with continuous NATO rails, multiple threaded mounts and an Arca-compatible base for faster switching between tripod heads and gimbals. Moment also uses an adjustable clamp that can slide to suit different camera layouts, which matters on phones where lens positions vary widely between models. The SuperCage is listed as compatible with recent iPhones, including the iPhone 17 Pro series, as well as Samsung Galaxy S22 to S24 and Google Pixel 7 to 9.
The main drawback is cost. The cage alone is priced at $199, while handles, a cheese plate and cables are sold separately, pushing a full setup far higher. Moment offers bundles, including one with Bluetooth handles, and broader retailer listings echo that this is a premium accessory rather than a cheap add-on. Even so, for creators who already rely on a phone for video, the SuperCage is notable because it addresses the bottleneck that matters most: connectivity.
