Our take
Belkin F4U090btBLK is a compact four-port USB-C data hub with two USB-C and two USB-A connections. It suits peripheral expansion where laptop charging, video and a larger upstream bandwidth are not needed.
A USB-C laptop owner who wants four mixed USB data connections in a small travel hub and does not need charging or monitor output..
It is not for a laptop that must charge through the hub, a monitor attached to a downstream USB-C port, Ethernet/card workflows, or several devices needing independent 5Gbps links.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Belkin documents two USB-C and two USB-A peripheral data ports.
- The 2.5-inch host cable folds away for compact carrying.
- The maker states that 5Gbps is shared and that its USB-C ports do not provide video.
What to weigh up
- All four ports share the 5Gbps host link.
- No laptop pass-through charging is supported.
- The historical ASIN is associated by a reseller but not verified as a current Amazon offer.

Full review: how the features affect your choice
What the features mean for you
Choose it for a mix of USB peripherals
Belkin's four-port layout pairs two USB-C connections with two USB-A connections. That can help a laptop owner use newer USB-C accessories alongside an older keyboard, mouse or storage device. The host cable is built in and folds away. This is a data expander, so check both the accessory connector and the laptop host port before choosing it. The four connections do not include HDMI, Ethernet or card readers; compare the full layout if the desk needs those functions as well.
Share the USB bandwidth across devices
Belkin describes speeds up to 5Gbps shared across the connected ports. That is the stated interface ceiling, not a measured rate available to each device at once. Several active drives or transfers can share the host link, so use the computer's direct port for a single device when maximum bandwidth matters more than expansion. The count of four physical data sockets is useful for convenience but does not mean four independent 5Gbps channels.
Do not count on video or laptop charging
The maker says the hub does not support pass-through charging, and its downstream USB-C ports are for USB peripherals rather than monitor output. The host uses the integrated USB-C cable for data. If you need to charge the laptop while connected or add HDMI/DisplayPort, select a hub whose official specification includes those functions. The downstream USB-C shape should not be confused with a display-capable host connection or a power input.
Confirm the code and exact current offer
Belkin's support page identifies the F4U090 family; an indexed reseller record connects B09BC4JCH3 with F4U090btBLK. The current exact Amazon offer was not inspected. Search by the full SKU and compare the two-and-two port arrangement and short foldaway host cable. Do not confuse this mini hub with separate Belkin multimedia products that include charging or displays. The saved ASIN is a historical clue, not a claim about today's offer.
Account for the very short host cable
Belkin lists a 2.5-inch cable that folds into the hub body. That keeps the accessory compact for travel, but it also limits how far the ports can sit from the laptop. Check the physical layout of nearby plugs and the room needed for wider USB devices. A short integrated lead will not place a hub across a desk or behind a monitor. If cable reach is important, compare a cabled model and verify its length in the exact listing rather than expecting an extension from this design.
Keep the role of each downstream port clear
The two USB-C sockets are documented as peripheral data ports, and Belkin says they do not output video. The two USB-A connections provide additional data access, while the host cable connects the hub to the computer. The four-port count is therefore useful for mixed USB devices but does not turn the accessory into a display dock or charging station. Map the data and power needs of each planned device before buying, especially if a phone or external drive expects to receive power through its USB connection.
Choose the mini hub only when its omissions fit
F4U090btBLK may suit a portable setup that needs four USB data sockets and can accept shared bandwidth and a very short host lead. It is a poor match when a laptop must stay charged, a monitor should connect through USB-C, or wired networking and card imports are part of the same job. Those omissions distinguish this simple hub from a fuller dock. Check the full SKU and exact port face in the tagged search; the saved source does not establish a current offer or a new revision's configuration.
