A USB-C hub that fits on a keychain yet delivers full desktop-level connectivity has arrived, and at a price that makes it impossible to ignore. The latest addition to Benfei’s lineup of compact expansion tools is a three-port powerhouse: a 4K/60Hz HDMI output for monitors or TVs, a USB-A 3.2 port capable of 10Gbps speeds for high-end storage, and a USB-C passthrough with 90W charging to keep devices powered while in use.
The hub’s most striking feature isn’t just its performance—it’s its size. Designed to clip onto a keyring, it’s one of the smallest USB-C hubs on the market, making it ideal for travelers, remote workers, or anyone who needs a portable solution for connecting peripherals on the fly. The build quality leans toward practicality, with a metal reinforcement loop for durability and an 18-month warranty that covers virtually any failure without questions asked.
For power users, this hub eliminates the need to carry a separate dongle for HDMI, a bulky adapter for USB-A devices, or a dedicated charger. Whether you’re hooking up an external monitor in a coffee shop, transferring files from a high-speed SSD, or charging a laptop while using it, the hub consolidates everything into a single, pocket-sized accessory.
The specs that matter
- Display: 4K/60Hz HDMI output (supports up to 4K resolution at 60Hz refresh rate)
- Storage: USB-A 3.2 Gen 2x2 (10Gbps bandwidth, compatible with NVMe SSDs and high-speed flash drives)
- Power: USB-C passthrough with up to 90W charging (supports most modern laptops and tablets)
- Portability: Keychain loop for easy carrying; ultra-compact form factor (fits in a pocket or on a keyring)
- Warranty: 18-month unconditional coverage
- Price: $14 (down from $17)
What sets this hub apart from others in its class is the balance of speed and versatility. The 10Gbps USB-A port isn’t just for legacy devices—it’s fast enough to handle modern NVMe SSDs, making it useful for professionals who need to transfer large files quickly. Meanwhile, the 90W USB-C passthrough ensures compatibility with most high-wattage laptops, including gaming and workstation models. The 4K/60Hz HDMI output, while not pushing the limits of modern displays, is more than sufficient for most use cases, from business presentations to casual media consumption.
That said, there are tradeoffs. The hub lacks additional features like Ethernet or SD card slots, which some users might find limiting. The design also means no room for extra ports—if you need more than three connections, you’ll still require additional adapters. But for the vast majority of users, this hub covers the essentials without the clutter.
For those who prioritize portability and efficiency, this is a standout choice. It’s particularly well-suited for remote workers, digital nomads, and creatives who need to switch between devices frequently. The $14 price point makes it a no-brainer for anyone who’s tired of lugging around multiple adapters or dealing with incompatible ports.
Availability is currently limited to select retailers, with the hub priced at $14—a significant discount from its usual $17 listing. Given its compact size and feature set, it’s likely to remain a popular choice for users who demand convenience without sacrificing performance.
