(Steam Deck Verified) Works like a charm on Dual QHD 2560x1440 (1440p)
This could be one of those reviews where I tell you how well this works for work Zoom Meetings and the Monthly TPS Excel reports. But my primary concern was the Steam Deck my secondary concern was being able to see more work. Luckily it worked for both. The Steam Deck is capable of pushing to both 1440p monitors without any issues. I don’t have many AAA games, but if it helps: Hogwarts Legacy ran at full speed on auto detect (medium) graphics. No ghosting, no tearing, no lag. I tried No Man Sky for something with very high particle and blooming. Still ran like a champ. Mafia Definitive Edition runs like Estes Kefauver at a meeting of Murder Incorporated. If it runs on the Steam Deck this hub can push it… Remember my monitors are only QHD 1440p. One laptop worked amazingly. 1440p Zoom Calls, Excel Spreadsheets as far as the eyes could see. BOTH EMAIL AND CHAT OPEN ON THE SAME SCREEN! *Car salesman roof slap* This baby has so many pixels. The other laptop didn’t support video over USB-C nor Power Delivery. The USB hub worked very well as a USB hub though. The USB ports are all fast and reliable. My USB 3.x devices have varying speeds. I don’t think any device measured the full through put, but given the equipment I have to work with (it could be the equipments fault) I am happy with a 4.8 out of 5. Using the power delivery port on this hub will allow you to charge attached devices. Steam Deck charges, Laptops with USB-C Power Delivery charge. Laptops without power delivery will not charge. The ports with pictures of keyboards, please plug your USB Keyboard and Mouse in these ports. These ports are USB 2.0. They will run slow if any other devices are plugged into them. If your device does not support Thunderbolt, Alt HDMI, or Displayport over USB-C, You will not be able to use the video ports.

Great product, had an issue, they took care of it.
Purchased this to allow me to run one cable to a laptop and have monitor/power/external accessories all connect easily. After a few days I noticed my monitor would disconnect and I would need to unplug and replug the device. Reached out to Anker support and they responded quickly to help diagnose and then sent a replacement unit very quickly. Was seriously impressed with the support and follow up. Item has been working perfectly since - makes a great clean setup.

Worked like a Charm.
So satisfied. I’ve tried using extenders with usb hubs because the cable is too short for my Dj set up but the extenders don’t work. Not sure why. This one worked perfect with my own Dj tech tools green cable.

Does its Job!
In about a year of use I can say that it is a very functionable hub. All of the ports work but now recently I have had some issues in connectivity. Now the USBs, HDMI, are all fine but recently the ethernet is inconsistent as well as the pass through USB-C to charge the laptop. Those 2 ports for me are starting to not always connect but simply unplugging and replugging is a temporary fix and sometimes I just go to the original charger to charge the laptop or plug ethernet directly to the laptop. If the ports or the hub all fail then that will change the review down the line but everything else works.

Great hub. Highly recommend.
I have owned this hub for almost a year and I has been super solid. The best part is the thunderbolt cable that connects it to your computer is removable and replaceable. It has a nice long cable, but if it is too short just buy a longer Thunderbolt cable. Via a single Thunderbolt connection I have my Surface Pro 11 connected to duel 32" monitors, ethernet, power, external storage, and a keyboard/mouse dongle. I would highly recommend. Anker is my go to for this kind of product.
