Kensington SD5700T Review 2026 - Specs, Pros & Cons

Name: Kensington SD5700T Thunderbolt 4 Dual 4K Docking Station
Brand: Kensington
Price: 369.99 USD
Availability: InStock

The Kensington SD5700T was one of the first Thunderbolt 4 docking stations to hit the market, announced in late 2020 and shipping in early 2021. Built by a company best known for its laptop locks and enterprise accessories, the SD5700T brings that same security-minded, office-ready approach to its dock design, complete with dual Kensington lock slots and a sturdy gray aluminum chassis. With 11 ports, 90W of USB-C Power Delivery, and support for dual 4K@60Hz displays via its three downstream Thunderbolt 4 ports, the SD5700T covers the essentials for a single-cable desktop setup. It also has built-in speakers, something you rarely find on a docking station and useful for quick video calls or casual audio without external speakers. The dock is also one of the few Thunderbolt 4 docks to earn official "Works With Chromebook" certification from Google, making it a strong candidate for ChromeOS users alongside the expected Windows and macOS support. At its original MSRP of $369.99, it sat in the premium tier, though street prices have since dropped to a more competitive $250-290 range. The SD5700T does not include dedicated HDMI or DisplayPort outputs, so you will need USB-C to HDMI or DisplayPort adapters to connect monitors, which adds cost and complexity. Despite this limitation, the dock delivers reliable Thunderbolt 4 performance with a generous 3-year warranty backing it up.

Pros & Cons

What We Like

3-year warranty, the longest in the Thunderbolt 4 dock category
Official 'Works With Chromebook' certification for ChromeOS users
Built-in speakers, a rare feature among docking stations
Dual Kensington lock slots (Standard + Nano) for physical security
Three Thunderbolt 4 downstream ports for daisy-chaining or displays
UHS-II SD card reader with 312 MB/s speeds
No drivers required, true plug and play across all supported OSes
Compact, lightweight design at under 1 lb

What Could Be Better

No dedicated HDMI or DisplayPort output, adapters required for every monitor
Workaround: Purchase USB-C to HDMI or USB-C to DisplayPort adapters. Budget $10-20 per adapter.
90W Power Delivery trails CalDigit TS4's 98W, may not fast-charge 16-inch laptops
Workaround: Use the laptop's own charger alongside the dock for power-hungry 16-inch models.
No microSD card reader
Workaround: Use an external USB microSD reader, or use a microSD-to-SD adapter.
Only 11 ports total, significantly fewer than CalDigit TS4's 18 ports
Front USB-A port is USB 2.0 only (480 Mbps)
Workaround: Use this port for peripherals that don't need high bandwidth (mouse, keyboard, phone charging). Use rear USB 3.2 Gen 2 ports for storage devices.

Our Verdict

Very Good

The Kensington SD5700T is a solid, well-built Thunderbolt 4 dock that checks most of the boxes for home office and enterprise users alike. Its 90W Power Delivery is sufficient for most ultrabooks and 14-inch laptops, the three Thunderbolt 4 downstream ports provide flexible connectivity, and the UHS-II SD card reader is a welcome addition for photographers and content creators. The built-in speakers are a genuinely useful bonus. They will not replace proper desktop speakers, but they are perfectly adequate for video conferencing and notification sounds. Kensington's 3-year warranty is the longest in its class, especially in a managed office environment where the dual lock slots also add real value. However, the SD5700T falls short in a few areas. The lack of any dedicated video output means every monitor connection requires an adapter, which feels like an oversight for a dock at this price. The 90W power delivery trails the CalDigit TS4's 98W, which matters if you have a larger 16-inch laptop. The 11-port count, while respectable, is outclassed by the CalDigit TS4's 18 ports, and there is no microSD card reader. If you need a Thunderbolt 4 dock with strong ChromeOS support, enterprise security features, and a generous warranty, the SD5700T is an excellent choice, particularly at its current street price. But if raw port count and maximum power delivery are your priorities, the CalDigit TS4 remains the better investment.

Frequently Asked Questions

Does the Kensington SD5700T have HDMI or DisplayPort?

No, the SD5700T does not include any dedicated HDMI or DisplayPort outputs. It uses its three downstream Thunderbolt 4 ports for video output. You will need USB-C to HDMI or USB-C to DisplayPort adapters (sold separately) to connect monitors. This is the dock's most notable limitation compared to competitors.

Does the Kensington SD5700T work with Chromebooks?

Yes, the SD5700T is one of the few Thunderbolt 4 docks with official 'Works With Chromebook' certification from Google. It is fully compatible with Chromebooks running ChromeOS 91 or later that have a Thunderbolt 4 or USB-C port.

Can the Kensington SD5700T charge a MacBook Pro?

Yes, the SD5700T delivers up to 90W of power via USB-C Power Delivery through the Thunderbolt 4 host connection. This is enough to charge a 14-inch MacBook Pro during normal use. For the 16-inch MacBook Pro, 90W will charge the laptop but may not keep up under sustained heavy workloads. Apple recommends 140W for maximum performance.

How does the Kensington SD5700T compare to the CalDigit TS4?

The CalDigit TS4 offers more ports (18 vs 11), higher power delivery (98W vs 90W), 2.5GbE networking (vs 1GbE), and a dedicated DisplayPort output. The SD5700T counters with a longer warranty (3 years vs 2), built-in speakers, Chromebook certification, and dual Kensington lock slots. The CalDigit TS4 is the better dock for power users, while the SD5700T may appeal more to enterprise and ChromeOS users.

Does the Kensington SD5700T support dual monitors?

Yes, the SD5700T supports dual 4K@60Hz displays via two of its three Thunderbolt 4 downstream ports. You will need USB-C to HDMI or USB-C to DisplayPort adapters for each monitor. On Mac, dual display support requires an M1 Pro, M1 Max, or later chip. Base M1/M2/M3 Macs are limited to one external display.
