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.

Good Multipurpose Hub, Some Limits on Power Draw
I use this with a Dell Latitude 7430 with a 65W charger, and it works fine as a docking hub. The only problem I've encountered is when rebooting, the boot will pause with a warning message to tell me that the laptop may encounter reduced performance because it isn't able to receive the full 65 watts. I don't get that warning if I'm not running the power supply through the hub.
Otherwise, if I just use the hub as a port extender everything is fine. It has a compact design and is reasonably lightweight. It would be ideal for travel.
Like my other Anker hubs, it's well constructed and doesn't feel cheap although it's good value for money.

I don't know how I ever lived without it.
I'm very happy with this device. My laptop doesn't have an ethernet port and only has one USB-C SuperSpeed port, so I bought an ethernet to USB-C cable to connect my ethernet switch to the Anker and into my laptop's USB-C port, and it works great. I don't need a fast internet connection for the things I do, so my service is only a 50mbps symmetrical up/down connection, and that's what I get even while transferring files from my external between other devices, charging my phone, and using composite devices.
I bought the Anker 100W Compact and Foldable USB C Charger for it and it charges my S24 extremely fast.
It's very well built, yet super lightweight. I love the sleek, slender design. It's the perfect size to easily slide into a pocket, store in a desk drawer, or keep handy in a laptop case or backpack.
Using it is easy. Just plug it into your computer and plug your devices into it. Just make sure you have a power supply for it if you're charging or powering other devices, using external storage, or running anything else that taxes USB power.
I have had ZERO connectivity issues with it — no random disconnect/reconnect blips, no failed transfers for huge amounts of data that have taken up to 45 minutes, no static his or crackle when my headset is running through it... no problems at all. It's actually kind of spooky now that I think about it... I can't recall a time I've ever had a similar device that didn't have some nuance that got under my skin, like a loose connection, random disconnections, having to reinstall the drivers all the time, or having to troubleshoot just to get it connected for the first time.
The most stress I've put it through was with my keyboard connected, ethernet running through it, my S24 charging and transferring about ~20gb of pictures and videos to my 2T external HD at the same time that my laptop was transferring about ~500gb of media and documents to the HD, too, and I was surprised by how warm it DIDN'T get.
My only complaint is trivial and unique to my situation — I wish output cord was longer. About six inches would do. My laptop sits up on an adjustable stand that clamps to my desk, and the end where the output cord is hangs a few inches off of my desk. This puts extra stress on the USB-C port and can wear it out faster or damage it.
I haven't had a use for the HDMI port yet, but I eventually will. I use all of the other ports for my work and personal devices, though. These include: a 2tb external hard drive; a Poly Blackwire 3320 Series headset; a dongle for a wireless mouse/keyboard combo or a wired keyboard and a dongle for a wireless mouse; my Galaxy S24 charges and transfers files through it super fast; I have several thumb drives ranging from 20gb to 512gb that I regularly use; I recently bought an RCA/S Video-to-USB converter to digitize old home movies I plug into it, too.

Anker wins again.
Worked well for usb hub but hdmi was not reliable. Disappointed because usually Anker products are good quality. UPDATE: Anker voluntarily offered a refund so my faith in Anker has been fully restored.
