This article covers Kensington Microsoft Surface Dock.
Overview
The Kensington SD4845P is a purpose-built docking station designed exclusively for Microsoft Surface devices. A single USB-C cable connects your laptop to up to three external displays while simultaneously delivering 85W of Power Delivery charging. This dock carries the "Designed for Surface" certification, meaning it was developed in direct collaboration with Microsoft to ensure seamless compatibility. It supports a wide range of Surface devices including Surface Pro 11, 10, 9, 8, 7, X, Surface Laptop, Surface Go, and Surface Laptop Studio. With dedicated HDMI 2.0 and DisplayPort 1.4 ports, you can build a multi-monitor setup without needing any dongles or adapters. The dock supports up to dual 4K@60Hz displays or triple 1080p@60Hz displays, making it a solid choice for productivity-focused users.
Connectivity & Compatibility
The SD4845P offers one USB-C 3.2 Gen 2 port (up to 10Gbps), three USB-A 3.2 Gen 2 ports (up to 10Gbps each), with one USB-A port supporting BC1.2 fast charging at 5V/1.5A. A Gigabit Ethernet port provides stable wired networking, and a combo audio jack handles headsets or speakers. Compatible devices include any Surface model with a USB-C port: Surface Pro 11/10/9/8/7/7+/X, Surface Laptop, Surface Laptop Studio, Surface Go, and Surface Laptop Go. Note that Surface Book series and older USB-A-only Surface devices are not supported.
Product Info
Launched in 2022, the Kensington SD4845P remains a current product positioned in the mid-to-high-end segment. Its key differentiator is the Surface-specific certification and dedicated video ports, which eliminate the need for additional adapters. The dock measures 19cm wide, 8.5cm deep, and 2.7cm tall, weighing approximately 400g. A mounting stand is included, allowing vertical or horizontal placement on your desk. Kensington backs this dock with a 3-year warranty and lifetime technical support. It is also TAA-compliant, making it suitable for government and enterprise deployments.
Best Use Cases
Remote Workers & Home Office Users If you use a Surface laptop as your primary machine and need multiple monitors at home, this dock is an excellent fit. One USB-C cable handles charging, video output, and peripheral connections, keeping your desk tidy. However, if you own a Surface Book or an older Surface without USB-C, look elsewhere. Creative Professionals Photo editors and video editors who need expansive screen real estate will appreciate the dual 4K@60Hz capability. The dedicated video ports ensure stable, high-resolution output. That said, heavy 3D rendering workloads may be limited by the Surface device's integrated graphics rather than the dock itself. IT Administrators in Enterprise & Education With TAA compliance, a 3-year warranty, and lifetime support, the SD4845P is well-suited for bulk deployments. The Designed for Surface certification minimizes compatibility headaches across a fleet of Surface devices. The main trade-off is price: it costs more than generic USB-C hubs, so budget-conscious organizations may want to compare alternatives.
Things to Consider
This dock is strictly for USB-C equipped Surface devices. It will not work with Surface Book or older USB-A-only models. Also, triple-display output is limited to 1080p@60Hz; for 4K resolution, you are limited to dual displays. The included USB-C cable is only 1 meter long, which may restrict desk placement options. Consider using a longer certified USB-C cable if your setup requires more distance. Key competitors include Microsoft's own Surface Dock 2 (which uses the proprietary Surface Connect port) and universal Thunderbolt 4 docks like the CalDigit TS4. The Surface Dock 2 offers native compatibility but lacks USB-C video output, while the CalDigit TS4 provides more ports and faster speeds at a higher price point without Surface-specific certification. Overall, the Kensington SD4845P is a reliable, Surface-focused docking solution that excels at multi-monitor productivity and 85W charging. It is a strong choice for anyone deeply invested in the Surface ecosystem.
