Review: Great Used Product! Used with T460 - I purchased a used-like new option from the seller Abe’s Electronics Center. I was a bit nervous that the product might not be in great shape with being used but wanted to save some money. This option was about half the price of a new one. Well, it paid off! The one I received was packaged like a brand new one. It included the key for locking the dock and a power cable. Everything was brand new. Based on what I can tell, the only reason that it was marked as used was due to a few scratches that are barely visible which probably occurred during manufacturing. Everything else indicates that this was probably never used. I just wanted to put that out there in case anyone else is considering a used option to save some money. It was worth it! In regards to the dock itself. The dock works great! I wanted to use two monitors in addition to my Thinkpad T460 but the laptop only has one HDMI outlet. The doc has one HDMI and two Display Port outlets. I didn’t have any Display Port cables but ordered some that came quick. They are a great option and provide amazing resolution to my two 27 inch monitors. It also has an option for an Ethernet cable which is really nice if you want to get better speed while docked. I use this computer for work and the dock has not affected the speed or functionality of my computer. My laptop clicks right into place seamlessly making it really easy to use. It also comes with a key to lock the dock so that you don’t accidentally undock it. I don’t think that you would be likely to undock it accidentally since the release button is out of the way but it’s nice to have the added security/peace of mind. Another added bonus is that it keeps constant power to the laptop and my laptop stays charging. So when I need to move somewhere else, it is fully charged up. Unfortunately, I was only able to use this for about three weeks before my work decided to upgrade my laptop to an HP. Even though it was only three weeks that I got to use it, I would recommend this to anyone that has a Thinkpad. It’s really a game changer in my opinion! If you are looking to add a few monitors, simplify your setup, or minimize the amount of cables you have to unplug when moving your laptop, I highly recommend this! Review: An astonishing value - I've been a Thinkpad user for decades. There are certain aspects of the brand that just work for me. The dull black plastic looks good after years, the clunky look is durable and timeless, the keyboards are almost always very pleasant and easy to type on, even on an airplane, and these docks. This dock looks very similar to the one I had 15 years ago for my IBM built thinkpad. I'm using this with my pair of T440 laptops, cheap old laptops that have excellent keyboards and are a steal to buy refurbished. though it's not listed in the compatibility list, it works flawlessly. The laptop slides very easily onto the dock, even with the extended life battery, and pops off very smoothly, without a click or any real mechanical noise. It's a nice improvement over the older docks. You get tons of USB ports, an HDMI port, a few other video ports. Truthfully the T440 isn't powerful enough to support a bunch of screens anyway, but you could run a pair if you wanted, and there are much more powerful laptops compatible with the dock. For the low price of this product, you get a really convenient way to connect a desk of accessories, and the T440 didn't have a normal HDMI port anyway. If this is compatible with your Thinkpad, it's a really good bargain and I found no defect with the way the laptop docks (some reviews for some docks complain about design flaws, but this model doesn't seem to have them. ## Features - 3x USB 2.0 and 3x USB 3.0 - 2x DisplayPort 1.2, 1x DVI-D, 1x HDMI 1.4 and 1x VGA (max two displays, including laptop screen) - Comes with ThinkPad US AC adapter (90W) Does not support ThinkPad T460p quad-core models with discrete graphics.

(I think this is for want of PCI-E bandwidth; my TB docks are dual 4k but the laptop's TB3 lane is only 2x.) My first complaint about this thing is that it didn't actually come with a slim-tip AC adapter. Instead, it came with the old barrel-type and a very short adapter cable. That adapter cable caused problems for me, but I only noticed the problem after I had dropped and stepped on it, so that may not be Lenovo's fault at all. The problem is that due to slight tweaks or a will o' the wisp, the power would get cut to the device, and when it powercycled, my monitors didn't come back. I picked up a very cheap, third-party, aftermarket slim tip adapter with decent reviews, and I've had no problems of that kind since. LIMITATIONS: For multi-monitor use, the bandwidth limitations on the two DisplayPort ports on the dock allow only 3840x2160@30Hz each. This can be troublesome if your monitors use more bandwidth than that. Both monitors I have hooked up are that way: one is 3840x2160@60Hz and the other is 2560x1440p@165Hz. This means that with both plugged into the dock, sometimes only one will show up or give any output, but this can be worked around. Additionally, each DisplayPort port is paired with another video port of a different type, and only one of each pair can be used together. So it supports only two monitors. I have had no success daisy-chaining standalone MST hubs to try to add a third monitor, but I have only tried with one so far. LINUX QUIRKS You will need a recent Linux kernel for this to work. I'm running Linux 5.3 on NixOS. Additionally, sometimes a monitor will not show up in the KDE graphical display management tools, even though it is visible in the output of `xrandr -q`. Even when the graphical display is broken, however, VTs pretty much always work. So I have gotten my monitors to behave by instructing xrandr to set the resolutions and refresh rates from the virtual terminal, then quickly switching back. My shell is Fish, so the command in my specific case is this: sleep 10s; xrandr --output DP2-1 --mode 2560x1440 -r 60; xrandr --output DP2-2 -m 2560x1440 -r 60 and then switching back to the VT of the display server. OTHER NOTES: The laptop runs really hot most of the time when it's closed and pushing as many pixels as it can on the two external monitors. ## Frequently Bought Together - Lenovo ThinkPad USA Ultra Dock With 90W 2 Prong AC Adapter (40A20090US, Retail Packaged) - AVACON 4K DisplayPort to HDMI 6 Feet Gold-Plated Cable 2 Pack, Uni-Directional DP 1.2 Computer to HDMI 1.4 Screen DisplayPort to HDMI Adapter Male to Male Black - ViewSonic VX2452MH 24 Inch 2ms 60Hz 1080p Gaming Monitor with HDMI DVI and VGA inputs,Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/1325490-thinkpad-usa-ultra-dock-with-90w-2-prong-ac-adapter](https://www.desertcart.tn/products/1325490-thinkpad-usa-ultra-dock-with-90w-2-prong-ac-adapter) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-08*
