I've always been a huge Anker fan. Their products are of great quality and I've never had any issues with them. So when I was buying a new Macbook Pro and wanting to set up a docking station setup for my desk I specifically looked for an Anker dock. One of the most important things to me was the ability to make my desk as minimalistic and clutter-free as possible. This dock is different from most in that it plugs directly into the 2 lightning ports without using a dongle/cord. That allows for a clean and solid connection and mount. It is a little more expensive than the others with less connections, but it had what I needed and was the cleanest. I bought the prior version because the newer version is $10 more and only has a lightning audio output which would only be useful for corded Apple earbuds I believe. I didn't need that. It also has the ability to have power pass through which allows you to plug your charger into one of the USB-C ports and when you dock it instantly starts charging. Here's what I have plugged into mine: - HP monitor in HDMI (had extra laying around) - Logitech webcam into one USB - Anker 60W charger - Pebble USB-C speakers (these are awesome and use the USB-C for both power AND audio output eliminating the need for another 3.5mm aux cord. This is crucial because it allows you to dock the laptop and have everything functional with the single dock rather than have to plug an extra cord in as well) I also have an Apple Magic Mouse and Magic Keyboard which are Bluetooth rather than USB wireless so they do not need a spot on the dock. This setup has worked seamlessly and is so much more ergonomic for long Zoom workdays on a larger monitor than staring at your laptop screen all day. It also gives you the flexibility of a laptop by being able to undock and take your computer anywhere. It really is the best of both worlds. Great work by Anker yet again!

Love it

Style: 7-in-2 4K@30Hz

The color and finish are almost a perfect match for 2020 space gray MacBook Pro. I don't have a great eye for colors, but I'd say it is a smidge darker. It is only a couple of millimeters higher than laptop body when in place, but not noticeable since it is slightly curved upwards. It truly looks like it belongs there. I returned another type due do HDMI issues (popping and flickering) and so far this one is very good. (I think I have a 1080p monitor. It is set to 60Hz.) It get medium-hot, but not at bad at all. You won't be placing your hands or arms there. I really wish it had an Ethernet port. Edit, 9 months later: Tried to use the microSD and SD card slots for the first time. They don't work. Way too late to return. Disappointing. Dropped review by one star. Edit 2: Raised by a star again. Anker saw my last edit and sent me a replacement. Works perfectly. I use this every day (just rarely for microSD cards, which is why I never noticed). I tried putting the old one and new one on (one has to be upside down) but I can't use the two HDMI ports together and had to stick to one from this hub and another dedicated HDMI dongle. Anker might want to consider making this so it can fit on either side of Mac and be flush both ways. If you could hook up two and use the HDMI ports on both, I could do away with 2 dongles (HDMI and an additional USB hub).

Saved Me From Buying A New Monitor

Style: 7-in-2 4K@30Hz

The MacBook Pro I use does not have an HDMI port for an external monitor. I had been using another hub that included an HDMI port which worked fine, but after 4 years it started wearing out. I didn’t immediately know this was a problem. My monitor had been flickering for some time, and eventually stopped working altogether. After much troubleshooting with inconsistent conclusions, I made the decision to try this hub. It works beautifully. My monitor started right up when I plugged it in. The hub fits right into the two USB-C ports on the left side of the laptop, and matches the computer. It makes a snug fit, so feels very secure. It includes all the ports I need. With 2 USB-C ports, I didn’t lose the two that are used to receive the hub. I like the fact that it feels like a part of the laptop and doesn’t connect like a dongle. Really happy with the product, and I didn’t have to replace my monitor.

Great little hub for MacBook Air!

Style: 7-in-2 4K@30Hz

I reviewed many before buying this one, and it suits my needs perfectly! I run my MacBook Air in clamshell mode, lid closed most of the time driving a 43” 4K tv as my my main monitor when used at home, and the hdmi port supports 4K so you can happily run in 3840x2160 mode. Just make sure you get an hdmi cable that has the bandwidth to support 4K I.e. hdmi 2.1! The dock fits closely to side of MBA and plugs into both usb-c ports so you have full power delivery. It feels a high quality design, nicely engineered and takes up so little room in a MacBook slipcase!

Highly recommend.

Style: 7-in-2 4K@30Hz

The best travel hub I’ve ever received. Hardy and works incredibly well when I’m on the go literally has downsized the number of charging bricks and other peripherals/dongle. I need to carry with me. It makes it very easy to use the TV in your hotel as a second monitor.
