Anker 11 in 1 Docking station as a Starter.
This is an entry level addition to a PC. If more ports needed then the 14 in 1 or a powered Hub.

Works as intended
I've been into emulators lately and this is a great HDMI out with charging capabilities to go with your high speed charging brick. Doesn't work for everything, but I can attest it works with the AYN Thor and a Google Pixel 8 Pro, and presumably higher end Pixels. Both have emulators and both come thru my TV just fine. Also works with Kodi. I tried to use wired controllers, but quickly figured I'm better off going Bluetooth on that route. I haven't tried file transfer or anything because all that mattered to me was getting it to the big screen. I'd rather have a docking stand for my needs, but freedom and flexibility isn't a bad thing for this device at a decent price and cheaper than a dock.

Versatile hub adds the ports my Mac lacks
This 7-in-1 USB C hub from Anker has made it easy to connect my laptop to all the devices I need. The HDMI port consistently outputs 4K video at 60Hz, while the USB 3.0 ports and SD/microSD slots transfer files quickly without errors. I appreciate that the pass-through charging allows me to power my MacBook while using the hub, and the unit itself feels solid and well made. It's truly plug-and-play, with no drivers to install, and it greatly expands the limited port selection on modern laptops. The only minor drawback is that the hub can get a little warm under heavy use, but overall it's a reliable, convenient accessory that I feel confident recommending.

Awesome USB-C Hub
My new MacBook Air has USB-C ports only, so I recently upgraded to this USB-C hub, a 7in1 Multi-Port USB-C Adapter, and it has completely solved all of my port needs. With the two USB-A ports, I can still use my old memory sticks, without replacing them, as well as two USB-C ports, all making moving files, movies and pictures, with ease. I needed something fast and reliability, and this little device delivers on both fronts. One of the USB-C ports it a power passthrough, which works great for charging device, like my MacBook Air. It is very easy to use, just plug and play, making it compatible with the MacBook Air. Also has a built in card reader, and a HDMI port, pretty much covering all your port needs. If you are looking for a well built, reliable, fast, and compact USB-C hub that can everything, this is the one to get. Highly recommended!

Good value and best of all - it works
This did the job I wanted it to. Expanded the ports when my laptop just ran out. No delay or ANY issue no matter what I plugged where and after a little figuring out where things went (not difficult) its performing very well. As far as value, its great. I always evaluate something by if I would purchase it again. Yes I would. if you need it, get it and set it up and move on with less worry about port capacity.
