Host connection The documented upstream protocol and connection limits. Connector shape is not protocol support. A backward-compatible connection may lose some features.	40 Gb/s Thunderbolt host path; USB and other host configurations have separate display limitations.

Maximum documented host charging The host charging limit for the reviewed package, not the power supply rating. The host must accept the offered power. A model sold in multiple revisions needs package-specific evidence.	90 W Source · 2026-10-11 OWC: Thunderbolt Go Dock US/International productChecked 2026-10-11.

Charging conditions Revision, host and rated-versus-certified qualifications. Do not promise full charging under every workload or substitute the adapter wattage.

Ethernet conditions Host and driver qualifications for the network port. A physical network connector is not proof that the port works over every upstream connection.	A rated network link is not a measured file-transfer result; the host, driver, switch and cabling remain dependencies.

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.	Use the manufacturer host/display matrix. GPU, operating system, display mode and any adapters control the usable simultaneous arrangement.

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.	Verify the exact computer and required display adapters.
