This adapter is unique in that it supports reverse charging + video on the same port. I use this with an LG monitor (60W PD) and an M1 Pro Mac. At first, I had connectivity issues: hub was disconnecting and reconnecting every few seconds. I followed advice to update the firmware on the hub, but that didn't solve the issue. Turns out, my monitor also needed a firmware update. Once I updated the monitor firmware, it stabilized and has been working great ever since.

Works perfectly with Macbook Air M2 - power, audio, video, sleep/wake, in clamshell mode!

My monitor has a USB-C video input that supports power delivery - so I was supposed to be able to charge my laptop with the same connection that goes to the monitor. Have had trouble finding an unpowered hub that actually supports all this without any hiccups, but according to all the specs I knew this was supposed to be possible. But this one does! Now I can connect my apple laptop to my monitor, keyboard and mouse, and run in clamshell mode or with the laptop open, and it charges, wakes from sleep, does all the things I want. It also sends audio to the monitor (as it should). And I only need one USB-C connection to my laptop to do all this. Note: I just got this hub so I don't know about longevity, and I haven't tested transfer speeds from all the ports on the hub, because that's not a big concern for me.

So far, so good. It's a USB-C hub, Anker has been doing USB hubs and power supplies for many years

I've always been impressed with Anker products, and great customer service! I do feel like they are starting to abandon the Android side of things recently, and the selection of cables has declined. USB-A cables seem to be discontinued, as well as USB-B. I did have a really great CSR experience a while back. I had bought a Lithium Ion car battery jumpstarters, and had not used it for several years. I needed it one night, and the cables to connect to the battery had failed. Couldn't start my car. Even though the warranty was expired, and the product was even discontinued, they shipped me (at their cost) a replacement set of cables. Now a loyal customer.

good on 16-inch MacBookPro and ThinkPad but not 13-inch MacBookPro; intermittent USB 3.2 connections

UPDATE 2025-NOV - lowering to 3-stars: Found that only the 2nd USB-C from the right is truly USB 3.2 compliant. Using the same SSD and same USB-C 3.2 cable, only the 2nd port from the right connects at 10Gbps speeds for RTL9210B-chipset enclosure SSDs (and I have tested with 4 different ones). The other 2 ports on this Anker adapter are intermittent, sometimes they connect the SSD as USB 3.0 and sometimes it connects as USB 2.0, for the same SSDs. The odd thing (as possible workaround) is that if we use a USB-C to USB-A female adapter and then use a USB-A to USB-C cable to the same SSD, it now connects at USB 3.0 speed on any of the ports, but transfers only at 5Gbps throughput. Another annoying thing is, this Anker adapter, even after the firmware upgrade, still intermittently "sleeps" or "goes offline" and disconnects from the laptop (does this on both my MacBook and ThinkPad). It does automatically reconnect after a few seconds, but very annoying, and can possibly corrupt drives that are connected when it happens. ORIGINAL REVIEW - 4 stars: USB-C hub is fast, able to transfer 5+ Gbps to SSD. Video display quality is OK for 1440p (when it works). DisplayPort video worked on ThinkPad and 16-inch MacBookPro, but not on 13-inch MacBookPro; connecting to a USB-C connected monitor (video worked without this Anker adapter). USB-C cable length to host computer is long enough. Worth the $30 price I paid ... yes; it served the purpose of having a USB-C hub while still being able to use the USB-C port for DisplayPort video; overall good design.
