CIO Co., Ltd. released the "CIO Cerberus" on September 18, 2026, a cable organizer that gathers three retractable USB-C cables into a single dedicated cradle[1]. Designed to tidy up the tangle of charging cables that tends to build up on a desk, it lets users pull out a cable only when needed and tuck it back in once they are done, and it is priced at 7,480 yen (tax included)[1].
Born From a Self-Made Gadget on monograph
The CIO Cerberus originated from an idea by Hidetaka Horiguchi of "monograph," a media outlet covering everyday goods[1]. It began in 2024, when Horiguchi shared a YouTube video of a device he had built himself: three retractable USB-C cables bundled together so they could be managed under a desk and pulled out only when needed, which he named "Cerberus"[1].
The idea of tidying up cluttered cable setups struck a chord, and the video's comment section filled with requests to turn it into a real product[1]. CIO shared that enthusiasm and began developing the product together with Horiguchi, aiming for a design where users could "pull it out quickly when needed and have it return to its place once finished," resulting in the CIO Cerberus now on sale[1].
Three Cables in One Cradle, Pulled Out With One Hand
The cradle holds three retractable USB-C cables together, consolidating the charging cables used around a desk for smartphones, tablets, and laptops into a single spot; users pull one out only when needed and tuck it back once finished[1].
To make cables easy to grab even when the unit is mounted under a desk, CIO paid close attention to how the USB-C connector itself is handled. Flicking the connector upward from below with a finger raises it to roughly 60 degrees, and CIO's own guide-cut shape on the cable outlet makes it easier to find and pull the connector by feel in spots that are hard to see, such as under a desk[1]. Inside the cradle, a guide structure holds each of the three reels in place, with magnets pulling them back into position[1].
The built-in USB-C cable measures about 67cm on the reel side and about 11.6cm on the fixed side. It supports USB Power Delivery 3.0 for charging at up to 100W, covering everything from smartphones and tablets to compatible laptops (DisplayPort Alternate Mode is not supported)[1]. According to CIO's Amazon.co.jp product listing, it also supports USB 2.0 data transfer at up to 480Mbps, useful for moving files between a laptop and a smartphone[2].
A Two-Way Mounting Design for On-Desk or Under-Desk Use
The bottom of the cradle has a built-in magnet, so it can be mounted directly on surfaces that attract a magnet, such as steel desks. For wooden desks or other surfaces where a magnet will not work, 3M double-sided tape is included, allowing the cradle to be mounted under a desktop so the cables stay out of sight during everyday use[1].
Each of the three reel units can also be detached individually from the cradle, and at under 6cm on each side, they are compact enough to fit in a palm. Users can pull out a single unit to carry in a gadget pouch or bag for business trips, working at a cafe, or bringing to meetings[2].
Standalone "CIO SnapReel Cable" Also Launches
The retractable USB-C cable used inside the Cerberus is also sold on its own as the "CIO SnapReel Cable." It is a one-pull retractable cable that extends only as far as needed and retracts with a single tug once you are done, priced at 2,400 yen (tax included) and available in the same black and white color options as the Cerberus[1].
Summary
The CIO Cerberus turns a self-made idea that went viral on YouTube into a real product, developed jointly by CIO and the original creator. It brings three retractable USB-C cables together in one place, supports charging at up to 100W, and offers the flexibility to be mounted either on top of or underneath a desk. It is priced at 7,480 yen (tax included) and has been on sale since September 18, 2026.
