CalDigit TS4 vs Kensington SD5700T - Thunderbolt 4 Dock Comparison 2026

CalDigit TS4 vs Kensington SD5700T: Two Premium Thunderbolt 4 Docks

The CalDigit TS4 and Kensington SD5700T are both premium Thunderbolt 4 docking stations aimed at users who want a single-cable desktop setup with dual-display support, laptop charging, and lots of downstream connectivity.

The difference is that they prioritize different things. The CalDigit TS4 focuses on maximum connectivity and higher-end specs. The Kensington SD5700T leans more toward office and enterprise use with a 3-year warranty, Chromebook certification, and security-minded extras like dual lock slots.

The short verdict: the CalDigit TS4 is the better dock for most buyers. It has a higher score in our reviews, more ports, faster Ethernet, more charging power, and more card-reader flexibility. The Kensington SD5700T is still a solid pick if you care most about Chromebook certification, a longer warranty, or built-in speakers.

Quick Specs Comparison

Design and Desk Fit

Both docks are compact desktop units with external power supplies and included 0.8m Thunderbolt 4 host cables, but they appeal to slightly different buyers.

The CalDigit TS4 uses a premium aluminum enclosure and is positioned as a high-end dock for power users on Mac and Windows. The Kensington SD5700T also uses an aluminum chassis, but its appeal is more office-focused. Its product positioning emphasizes dual Kensington lock slots for physical security, a compact lightweight body, and official Chromebook certification.

A small but practical difference is built-in audio. The Kensington SD5700T includes built-in speakers in addition to its 3.5mm combo jack, while the CalDigit TS4 focuses on port variety and gives you separate combo, headphone, and microphone connections.

Design winner: Tie, with different strengths. The TS4 feels more premium and feature-dense, while the SD5700T brings more office-friendly extras like lock slots and built-in speakers.

Ports and Expandability

This is the category that decides the comparison for many buyers.

CalDigit TS4 port advantage

The CalDigit TS4 delivers 18 total ports, including:

• 3 Thunderbolt 4 downstream ports
• 3 USB-C 3.2 ports
• 5 USB-A 3.2 ports
• 1 DisplayPort 1.4 output
• 2.5 Gigabit Ethernet
• SD and microSD UHS-II card readers
• Three 3.5mm audio ports

That makes it one of the most complete Thunderbolt 4 docks in the category.

Kensington SD5700T strengths and limits

The Kensington SD5700T has 11 total ports, including:

• 3 Thunderbolt 4 downstream ports
• 3 USB-A 3.2 ports
• 1 USB-A 2.0 port
• 1 Gigabit Ethernet
• 1 UHS-II SD card reader
• 1 3.5mm combo jack

That is enough for a clean desk setup, but it is clearly less flexible than the CalDigit. The biggest missing piece is video output convenience. The SD5700T has no dedicated HDMI or DisplayPort ports, so every external monitor needs a USB-C adapter. The TS4 is not perfect here either because it only gives you one built-in DisplayPort output and no HDMI, but it still offers more built-in flexibility.

The CalDigit also wins on networking and media-reader flexibility. Its 2.5GbE port is faster than the Kensington’s 1GbE, and it adds a microSD reader the SD5700T does not have.

Port winner: CalDigit TS4. More total ports, more USB expansion, faster Ethernet, more audio outputs, and more built-in display convenience.

Display Support

Both docks support dual 4K@60Hz displays, and both require an M1 Pro, M1 Max, or later Mac if you want dual external monitors on macOS.

The Kensington SD5700T has more ambitious single-display specs on paper. Its YAML lists support for:

• Single 8K@60Hz with DSC enabled
• Single 8K@30Hz without DSC
• Single 4K@120Hz
• Dual 4K@60Hz
• Dual 1080p@120Hz

The CalDigit TS4 lists:

• Single 8K@30Hz on Windows
• Single 4K@60Hz
• Dual 4K@60Hz

So if your decision is based strictly on listed peak display modes, the Kensington has the stronger spec sheet. In real use, though, the main outcome for most people is the same: both are premium Thunderbolt 4 docks that handle dual 4K monitors.

Display winner: Kensington SD5700T on listed peak specs, tie for typical dual 4K use.

Power Delivery and Charging

The CalDigit TS4 delivers 98W of host charging. The Kensington SD5700T delivers 90W.

That 8W difference is not huge for lighter laptops, but it matters more if you use a 15-inch or 16-inch machine under sustained load. Kensington’s own editorial notes in the YAML acknowledge that 90W may not fast-charge larger laptops as effectively as the TS4.

Both docks require external power and both are fully plug and play with no drivers required.

Charging winner: CalDigit TS4. It offers more headroom for demanding laptops.

Compatibility

This is a closer category than the raw score suggests.

The CalDigit TS4 supports macOS, Windows, ChromeOS, and Linux, and its review content strongly emphasizes excellent Mac support and regular firmware updates.

The Kensington SD5700T also supports Windows, macOS, ChromeOS, and Linux, but it has one standout compatibility advantage: it is officially Works With Chromebook certified. That makes it especially appealing for ChromeOS users who want a dock with explicit validation.

Both docks share the same major Mac limitation: base M1, M2, and M3 MacBooks are limited to one external display, which is a host limitation rather than a dock problem.

Compatibility winner: Tie overall. The TS4 is stronger for broad premium Mac and Windows use, while the SD5700T has the clearer Chromebook story.

Pricing and Value

At MSRP, the two docks are very close:

• CalDigit TS4: $379.99
• Kensington SD5700T: $369.99

That makes the TS4 only $10 more expensive at list price, which is a very small gap considering the extra ports and faster Ethernet. On spec value alone, the CalDigit is the better deal.

The Kensington fights back with a 3-year warranty compared to the TS4’s 2-year coverage. If you are buying for an office rollout or want the longest support window, that matters.

Still, the overall value case favors the CalDigit because the price difference is so small while the hardware difference is much larger.

Value winner: CalDigit TS4. The SD5700T’s longer warranty is nice, but the TS4 gives you substantially more dock for nearly the same money.

Verdict: CalDigit TS4 Wins for Most Buyers

The CalDigit TS4 wins this matchup because it is simply the more capable dock on the facts that matter most to most buyers. It has a higher review score, more ports, faster Ethernet, more charging power, more audio connectivity, and more card-reader flexibility, all while costing only slightly more at MSRP.

The Kensington SD5700T is not a bad dock. It is a good Thunderbolt 4 option if you care about Chromebook certification, a 3-year warranty, built-in speakers, or dual lock slots for office security. But for overall capability, the CalDigit pulls ahead.

Choose the CalDigit TS4 if:

• You want the most ports and expandability
• You need 2.5 Gigabit Ethernet
• You want both SD and microSD UHS-II readers
• You want more charging headroom for larger laptops
• You want the highest-scoring overall dock in this comparison

Choose the Kensington SD5700T if:

• You want official Works With Chromebook certification
