Lenovo ThinkPad Docking Station Review
Upgrade your workspace with the Lenovo ThinkPad Docking Station. Revel in 13 versatile ports, dual 4K support, & seamless multitasking. Is it your next must-have?
A Lenovo ThinkPad dock sold by Koncept, not by Lenovo directly. The dock itself is the Lenovo 40AF0135US — a ThinkPad Hybrid USB-C with USB-A dock that connects to modern USB-C laptops and older USB-A laptops using included adapter cables. The “hybrid” means this dock does not require Thunderbolt or even USB-C on the laptop. A ThinkPad from 2016 with only USB-A connects to this dock through the included USB-C to USB-A cable. A current ThinkPad with USB-C connects through the USB-C to USB-C cable. Both get the same ports, monitors, and peripherals. This is a renewed unit with a 1-year warranty from Koncept, an included 135W Lenovo power adapter, an HDMI cable, a DisplayPort cable, and a microfiber cleaning cloth.
Fourteen ports: two DisplayPort 1.2, two HDMI, one USB-C 3.1 Gen 2 (10 Gbps), three USB-A 3.1 Gen 2 (10 Gbps), two USB 2.0, Gigabit Ethernet, stereo/mic combo audio, and Kensington lock slot. 135W power supply included. 1.05 lbs. Windows 10+ and ChromeOS 134+.

40AF0135US Lenovo Docking Station Dual Monitor Hybrid USB-C with USB-A - Thinkpad Dock with 135W, HDMI & DisplayPort Cable (40AF0135US)
Hybrid Connection: USB-C and USB-A Laptops
Most docks require USB-C on the laptop. The Lenovo 40AF0135US includes a USB-C to USB-A cable that connects laptops without USB-C to the dock. An older ThinkPad T450 with only USB-A ports connects through that cable and receives USB peripherals, Ethernet, and display output (resolution and capability depend on the USB-A port’s bandwidth). A newer ThinkPad with USB-C connects through the USB-C to USB-C cable at full speed. The hybrid approach means one dock covers both generations of ThinkPads at the same desk.
For IT departments refreshing docking stations before all laptops have been replaced, the hybrid dock bridges the transition. The old laptops work today. The new laptops work when they arrive. The dock stays.
Four Video Outputs: Dual DP and Dual HDMI
Two DisplayPort 1.2 and two HDMI provide four video output ports. The dock supports up to two monitors simultaneously. DP 1.2 runs up to 4K@60Hz per port. The two HDMI ports add connectivity for monitors with HDMI inputs. The package includes one HDMI cable and one DisplayPort cable, so two monitors can be connected immediately without buying additional cables.
Note: the original version of this review listed DP 1.4 and HDMI 2.0. The correct specification is DP 1.2. Lenovo’s official specifications for the 40AF0135US confirm DP 1.2. The ports drive dual 4K@60Hz through DP 1.2 on ThinkPads that support it, but DP 1.4 features like HDR and DSC are not available at the DP 1.2 specification level.
Five USB Ports at 10 Gbps, Two at 2.0
One USB-C and three USB-A at 10 Gbps Gen 2. The USB-C port also delivers 5V 3A for phone charging. The USB-A ports include Always-On USB, meaning they charge devices even when the laptop is in sleep mode or the lid is closed. Two USB 2.0 ports handle keyboard, mouse, and wireless receivers.
Five 10 Gbps ports is a generous count for this class of dock. For connecting multiple external SSDs, USB-C accessories, and fast peripherals simultaneously, five Gen 2 ports provide the bandwidth without bottlenecking.
135W Power Supply Included
The original Lenovo 135W adapter comes in the box. This is not a third-party charger. The 135W adapter powers the dock and charges the laptop simultaneously. 135W covers ThinkPad E-series (45-65W), L-series (45-65W), T480s (65W), and X1 Extreme (135W) at full speed. The included adapter matches the X1 Extreme’s maximum draw, which means every ThinkPad on the compatible list charges at full speed through this dock.

Where This Dock Fits in Lenovo’s Lineup
Lenovo’s ThinkPad dock lineup includes: the 7-in-1 USB-C travel hub (minimal, portable), the Travel Dock (dual 4K, compact), the ThinkPad USB-C Gen 2 Dock (this unit, 40AF0135US, hybrid USB-C/USB-A), the ThinkPad Universal Thunderbolt 4 Dock (TB4, vPro, HDMI 2.1), and the ThinkPad Thunderbolt 4 Workstation Dock (300W, P-series workstations). This dock sits in the middle — more ports and power than the travel options, but USB-C Gen 2 rather than Thunderbolt 4. For the Thunderbolt 4 upgrade, see the Lenovo ThinkPad Universal Thunderbolt 4 Dock review.
Who This Dock Is For
ThinkPad owners who need a full desk dock that connects to both USB-C and USB-A laptops, with a 135W Lenovo adapter, five 10 Gbps USB ports, dual display, Ethernet, and audio: The hybrid connection covers old and new ThinkPads at the same desk. Renewed at a lower price than new. Cables and adapter included in the box. 1-year warranty from Koncept. For Lenovo’s current TB4 dock, see the ThinkPad Universal TB4 review.
Non-ThinkPad owners, Mac users, or buyers who need a new-condition dock with Lenovo warranty: Compatible devices list ThinkPad models only. macOS not supported. Renewed condition with Koncept warranty, not Lenovo. For universal docks, see the docking stations hub page.
Final Verdict
The Lenovo 40AF0135US is a ThinkPad desk dock with hybrid USB-C and USB-A connectivity, sold renewed by Koncept with a 1-year warranty, an original 135W Lenovo adapter, and both display and host cables in the box. Fourteen ports with five at 10 Gbps, four video outputs, Gigabit Ethernet, audio, and a Kensington lock. The hybrid connection bridges older USB-A ThinkPads and newer USB-C models at the same desk setup. DP 1.2 rather than 1.4 limits advanced display features but delivers dual 4K@60Hz on supported ThinkPads. For IT teams deploying standardized desks across a mixed-age ThinkPad fleet, this renewed dock provides Lenovo hardware at a reduced price with everything needed in the box to connect two monitors on day one.

Docking Station Intelligence
The standards are confusing by design. These three panels decode what manufacturers won’t explain clearly. Applicable to every docking station.
The USB-C Confusion Matrix
The USB-C connector is the single greatest source of buyer confusion in docking stations. The physical plug looks identical whether it carries USB 2.0 at 480 Mbps or Thunderbolt 5 at 120 Gbps — a 250x difference in capability hidden behind the same shape. Manufacturers exploit this by labeling everything "USB-C compatible" without specifying which protocol runs through it. Two docks can look identical on the outside and behave completely differently once you plug them in.
The hierarchy matters because it determines everything: how many monitors your dock can drive, how fast files transfer, whether your laptop charges while docked, and whether you need third-party drivers. Here is the real capability ladder, from slowest to fastest:
The practical takeaway: if your laptop has Thunderbolt 4, buy a Thunderbolt dock. If it only has generic USB-C, verify whether it supports DisplayPort Alt Mode before buying anything with multi-monitor claims. Our buying guide walks through verification steps for every major laptop brand.
Power Delivery: What the Watts Mean
Power Delivery (PD) determines whether your docking station can charge your laptop while you work, or whether you need a separate charger cluttering your desk. The math is simple but rarely explained: your laptop draws a specific wattage under load, and the dock must match or exceed it. If the dock delivers less than your laptop needs, the battery slowly drains even while plugged in — defeating the purpose of a docking station entirely.
Most ultrabooks need 45–65W. Standard business laptops need 65–100W. Gaming and workstation laptops can demand 100–140W or more. The dock’s advertised PD wattage is the maximum it can deliver to your laptop — but this drops if you charge other devices (phones, tablets) through the dock simultaneously. Always leave a 15–20W margin above your laptop’s requirement.
Check your laptop’s original charger wattage — that’s your baseline. Our FAQ covers how to find this for every major brand.
Native Display vs DisplayLink: The Hidden Factor
This is the decision most buyers don’t know they’re making. When a docking station outputs video to your monitors, it uses one of two fundamentally different methods: native (the dock passes your laptop’s GPU signal directly to the monitor) or DisplayLink (the dock compresses video over USB and a software driver renders it). The difference is invisible in marketing materials but profoundly affects your daily experience.
Native output through DisplayPort Alt Mode or Thunderbolt uses your laptop’s actual graphics hardware. There is zero added latency, full DRM support for streaming services, no CPU overhead, and no driver to install. DisplayLink, by contrast, adds 5–15ms of latency (noticeable in video calls and cursor movement), blocks DRM content on connected monitors (Netflix, Disney+ show black screens), consumes 3–8% of your CPU constantly, and requires a driver that Apple’s macOS security updates occasionally break.
DisplayLink exists for one reason: Apple Silicon base chips (M1, M2, M3) can only drive one external display natively. If you need two or more monitors on a base MacBook Air or 13” MacBook Pro, DisplayLink is your only option. For everyone else — Windows users, Mac Pro/Max chip users, Intel/AMD laptops — native is always the better choice.
Native (Alt Mode / Thunderbolt)
DisplayLink (USB compression)
The bottom line: if your laptop supports native multi-display output, always choose a native dock. DisplayLink is a workaround, not an upgrade. See our glossary for detailed definitions.
