No annoying "Disk not ejected properly" messages!
Color: Space grey
I use these with MacBook Airs, both Intel and Apple M3, and they stay connected. Previous —cheaper—dongles kept disconnecting with no apparent moving of the computer or the dongle. I'd get the annoying "Disk not ejected properly" message repeatedly, meaning I'd have to remove the dongle plug, reinsert it, and hope that the external device showed up on the computer and stayed connected. These always stay connected and seem to work well for the external devices I use. I think it's in the plug: with the Acer, I hear a distinct little click when the plug is fully inserted—perhaps some subtle locking mechanism the cheaper dongles did not have.

Instantly addressed a defective unit
Color: Space grey
2nd EDIT: Not only did the company offer a refund, they also generously shipped me another unit, and it works just as it should! They gave fast responses when the first unit gave me issues, and addressed it as well as you possibly could. I would use them any time! EDIT: the company quickly reached out and offered a full refund as a result of a faulty product. For me, that goes a long way. I have plenty of ACER products and normally have no issues with them. could have just been a faulty single product. Very bummed. For the first 2 hours of use it worked great. When it’s just USB-C to HDMI connected it works fine, but the second I go to plug my Mac in, while using the HDMI to stream to my monitor, the screen begins flashing every second or two on both my Mac, and the monitor. The flashing screen is happening at the same time the Mac keeps making its “chime” that the charger is connected, over and over again. Clearly something is going on that the charging is not staying active. whenever the charger is first connected it causes a quick(ish)black screen, which I could live with if it just happened right as I plugged the charger in… but when the charger KEEPS thinkings it’s just getting plugged in over and over, and keeps flashing, it kind of makes the product useless. And I’ve already thrown the box away so I guess I’m stuck with a product that doesn’t work. Super bummer.

Beyond Impressed
Color: Space grey
I recently picked up the Acer 7-in-1 USB-C Hub and I have to say, I am beyond impressed with its performance and functionality. As someone who frequently uses a laptop for both work and personal tasks, this little device has completely changed the way I connect my peripherals and external devices. What I Love: Compact Design & Build Quality: Despite packing so many ports into such a small form factor, the Acer USB-C Hub is surprisingly lightweight yet feels sturdy. The sleek aluminum finish not only looks professional but also helps keep things cool during extended use. It’s incredibly portable and fits easily in my bag alongside my laptop. Wide Range of Ports: This hub includes 7 different ports, which is a dream for anyone who needs to expand their connectivity. It includes: HDMI port (4K support) for connecting to external monitors or TVs, USB 3.0 ports (two) for fast data transfer or connecting peripherals like keyboards, mice, or external hard drives, SD and MicroSD card readers (perfect for photographers or videographers), Ethernet port for reliable wired internet connections (a must for stable work-from-home setups), USB-C power delivery port for charging your laptop while using the hub. Whether you're using it for office tasks, media consumption, or creative work, this hub has you covered. Plug & Play: I’m a huge fan of how easy this hub is to use. There’s no need for extra drivers or software. Simply plug it into your USB-C port, and it’s ready to go! My MacBook, Windows laptop, and even my tablet all recognized the device instantly without any issues. Fast and Stable Performance: I’ve tested the data transfer speeds using both USB drives and external hard drives, and the speeds are consistently fast. The HDMI output worked seamlessly, delivering crisp 4K video to my TV without any lag or glitches. The Ethernet connection is a lifesaver when I need a stable internet connection for remote work or video calls. Affordable Price: Considering the versatility and quality, the price of this hub is a steal! Many hubs in this range only offer a handful of ports, but Acer’s 7-in-1 gives you a full suite of connectivity options at a great value. A Couple of Notes: Heat Management: During extended use, the hub can get a little warm, especially if you're using the HDMI output or transferring large files. However, it never got hot enough to be a concern, and it hasn’t impacted performance at all. Compatibility: While it works perfectly with laptops that have a USB-C port with power delivery, make sure your device supports it for full functionality. I haven’t had any issues with my devices, but it’s always a good idea to check your specs. Final Verdict: The Acer 7-in-1 USB-C Hub is an absolute game-changer for anyone looking to maximize their laptop’s connectivity. It’s a perfect solution for professionals, creatives, and anyone who needs to connect multiple devices without the clutter of extra adapters. I highly recommend it to anyone who wants to simplify their tech setup while maintaining top-notch performance! If you're looking for a versatile, high-quality USB-C hub, this is the one to get.

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.
