External rating	Not checked yet	4.4 out of 5 from 156 ratings · B&H Photo · Checked October 23, 2026.
Host connection The documented upstream protocol and connection limits. Connector shape is not protocol support. A backward-compatible connection may lose some features.	Thunderbolt 4 at up to 40 Gb/s. Belkin lists Thunderbolt 5, 4 and 3 and USB-C hosts, but full Thunderbolt 4 data, display and 96 W charging performance needs a Thunderbolt 4 or USB4 host.

Maximum documented host charging The host charging limit for the reviewed package, not the power supply rating. The host must accept the offered power.

Charging conditions Revision, host and rated-versus-certified qualifications. Do not promise full charging under every workload or substitute the adapter wattage.	Up to 96 W to the host from the supplied 150 W power supply; the supply rating is not laptop charging power. Peripheral outputs: 15 W on the downstream Thunderbolt 4 port, 30 W on the USB-C port and BC1.2 on the 10 Gb/s USB-A ports.

Display arrangement Documented display paths and host-dependent limits. Check exact resolution, refresh rate, host GPU and simultaneous-screen requirements. Do not add alternative connectors together.	Outputs: Thunderbolt 4 downstream, two DisplayPort 1.4 and one HDMI. Windows triple display runs one screen at up to 4K@60Hz and two at up to 4K@30Hz, first plugged, first served; DP 1.4 and DP 1.2 hosts are capped lower and extend only via DP #2 and HDMI. macOS supports at most two extended displays.The product-page technical specifications list HDMI 2.0, while the page FAQ and the sales sheet list HDMI 2.1; both state 4K@60Hz.

Built-in DisplayLink documented Whether DisplayLink is established as part of the dock itself. An optional external adapter does not become a built-in feature. Unknown does not mean absent.	Not verified We have not verified this value. It is not a confirmed no or zero. Check the original source or ask the manufacturer if it affects your choice. No explicit built-in DisplayLink declaration or denial was verified for this exact dock. Native display guidance does not settle every optional adapter.

Host and software requirements Important software, host and configuration conditions. Check the current manufacturer support page for the exact computer; no installed compatibility or security certification is claimed.	Belkin lists Windows, macOS and ChromeOS support.

Power arrangement and supplied equipment Built-in or external power and reviewed package contents. Confirm the regional mains cord before buying; a global product page is not a checked US checkout.

Questions to check before buying	The HDMI output is listed as HDMI 2.0 in the product-page specifications and as HDMI 2.1 in the FAQ and sales sheet; both state 4K@60Hz. This record is the Connect Thunderbolt 4 Dock INC030, not the older Pro Thunderbolt 4 Dock INC006, which has a different port set and charging rating. Display limits depend on the host and are not installed-system tests.	Read the source notes for the exact package and operating conditions.
