Belkin INC004 Review 2026 - 11-in-1 USB-C Dock Specs

Name: Belkin Connect USB-C 11-in-1 Multiport Dock
Brand: Belkin
SKU: INC004btSGY

The Belkin INC004 is a compact USB-C dock for laptops that need legacy display outputs and basic desk ports without Thunderbolt pricing. It turns one USB-C connection into HDMI 1.4, DisplayPort 1.2, VGA, Gigabit Ethernet, SD and microSD readers, three USB-A ports, a 3.5mm combo audio jack, and a USB-C Power Delivery input. Belkin lists the host link at 5 Gbps and the video side at up to 4K, but the details matter. The HDMI and DisplayPort ports top out at 3840 x 2160 at 30Hz for a single display, not 4K at 60Hz. Windows MST hosts can use multiple displays, but Belkin's own support table drops dual display to 1080p at 60Hz and triple display to 720p at 60Hz. macOS uses SST behavior, so it is better treated as a single-display Mac dock unless mirrored displays are acceptable. Power is also pass-through: the dock accepts up to 100W USB-C PD, uses about 15W itself, and can pass up to 85W to the laptop when paired with a suitable charger.

Pros & Cons

What We Like

Wide port mix with HDMI, DisplayPort, VGA, Ethernet, SD, microSD, USB-A, audio, and USB-C power input
Passes up to 85W to the laptop when used with a 100W USB-C charger
Built-in USB-C host cable keeps the desk setup simple
Wedge shape can sit under the back of a laptop and route cables to the rear
Includes both SD and microSD readers, which many newer USB-C docks omit

What Could Be Better

4K display output is limited to 30Hz
Workaround: Use 1080p or 1440p monitors for smoother 60Hz output, or choose a Thunderbolt or USB4 dock for 4K60.
Multiple-display support depends heavily on the host laptop and is limited on macOS
Workaround: For multiple independent Mac displays, choose a DisplayLink dock such as the Belkin INC007 or a Thunderbolt dock matched to your Mac's display limits.
USB-C port is power input only and does not add a downstream USB-C data port
Only two USB-A ports run at USB 3.0 speed, and the third is USB 2.0
Workaround: Use the USB 3.0 ports for storage devices and reserve the USB 2.0 port for a keyboard, mouse, or receiver.
No included power adapter, so full 85W laptop charging requires a separate 100W USB-C charger
Workaround: Pair the dock with a 100W USB-C PD charger if you need the maximum pass-through charging output.

Compatibility

Windows

Supports MST for multiple displays on compatible USB-C hosts with DisplayPort Alt Mode. Maximum resolution depends on the number of attached displays.

macOS

Works for USB, Ethernet, charging, card readers, audio, and display output, but Belkin's Mac support table uses SST behavior. Treat it as a single-display or mirrored-display Mac dock.

ChromeOS

Belkin lists Chrome OS support and compatible Chromebook models. Display output still depends on the host USB-C video capability.

Android

Belkin lists USB-C smartphones and tablets as compatible devices. Features depend on the phone or tablet's USB-C video and power support.

Known Issues

USB-C hosts without DisplayPort Alt Mode

Video outputs will not work

MacBooks needing multiple independent external displays

Extended multi-display support is limited

High-refresh 4K monitor setups

4K output is limited to 30Hz

USB-A only computers

Not compatible as a full dock

6.8 /10

Our Verdict

Good

The Belkin INC004 is useful when you want one small stand-style dock to cover old and new connectors. HDMI, DisplayPort, VGA, Ethernet, card readers, USB-A, audio, and 85W pass-through charging in one travel-friendly wedge is a practical mix, especially around $99.99 from Belkin. It is not the right dock for every desk, though. The 5 Gbps USB-C connection, 4K30 display ceiling, and host-dependent MST behavior make it a poor fit for high-refresh monitors, gaming, creative video work, or Mac users expecting two independent displays. Digital Camera World liked the broad port coverage and sturdy design, but also called out the lack of Thunderbolt, limited USB-C expansion, and slower USB-A ports. That lines up with the way this dock should be bought: as a flexible port expander for office work, presentations, and mixed legacy displays, not as a high-bandwidth workstation dock. If you need predictable dual or triple extended monitors, Belkin's DisplayLink-based INC007 or a Thunderbolt dock is a safer buy.

Frequently Asked Questions

Does the Belkin INC004 support dual monitors?

Yes, but the result depends on the computer. Belkin's Windows MST table lists dual displays at 1920 x 1080 at 60Hz. Its macOS SST table lists HDMI plus DisplayPort at 3840 x 2160 at 30Hz, but Mac users should expect mirrored-display behavior rather than the flexible extended desktop you get from DisplayLink or Thunderbolt docks.

Can the Belkin INC004 charge my laptop?

Yes. The dock supports up to 100W USB-C PD pass-through, but it uses about 15W to run the dock. With a 100W charger connected, Belkin says the laptop can receive up to 85W. The dock requires at least a 65W USB-C power supply for powered use.

Does the Belkin INC004 require drivers?

No DisplayLink driver is required because this is a native USB-C dock. Video output uses DisplayPort Alt Mode, MST on compatible Windows hosts, and SST behavior on macOS. That also means the laptop's USB-C video capability matters more than it would on a DisplayLink dock.

What ports are on the Belkin INC004?

The dock has HDMI 1.4, DisplayPort 1.2, VGA, Gigabit Ethernet, SD 3.0, microSD 3.0, two USB-A 3.0 ports, one USB-A 2.0 port, a 3.5mm combo audio jack, a USB-C PD input, and a built-in USB-C host cable.

Is the Belkin INC004 a good dock for MacBooks?

It is fine as a MacBook port expander for charging, USB accessories, Ethernet, card readers, audio, and one external display. It is not the best choice for multiple independent Mac displays. For that, look at a DisplayLink dock such as the Belkin INC007 or a Thunderbolt dock that matches your Mac's native display support.
