Works great and handles everything.
Color: Black
Works great. I plug in a standalone video camera for meetings, a keyboard & trackball, and monitor with a couple of other slots open, like for a portable CD-ROM/DVD player. One plug into the laptop and everything is connected. Initially, I bought another hub, but that one didn't consistently work. This one does. In a month of heavy use, I've had no issues with it at all.

Helped transfer data from Samsung Galaxy S21 with broken screen.
Color: Black
Helped me transfer data from a Samsung Galaxy S21 with broken screen. Simple put USB C end into phone , grab HDMI cable and plug into hub , then plug HDMI end into a monitor. Then grab a wireless keyboard & mouse and plug dongle into hub. Your phone will output to monitor and you can transfer data via Smart Switch using keyboard & mouse. Will only work if phone is unlocked I found on S21.

good so far!
Color: Black
Seems to work fine so far. The last one - different brand - had a bad connection and Im hopefully as I do always find Anker to be of good quality.

Best Charging Block Around!!!!!!!!!!!!
I’ve been using this Anker charging block for a bit now, and its great. First off, it’s just really stylish—it has that clean, premium look that blends right in with your other devices, but you can feel it's packed with some serious, heavy-duty tech. ​Having three ports on one block changes the game completely. You can plug in multiple items at once without losing speed. When you pair this block with a solid high-speed cord, the charging performance is incredible. Just this morning, I hooked up my phone and my monitoring app showed it was pushing an absolute peak of 4,800 mA straight to the battery. It juices everything up incredibly fast without getting hot. If you want something compact, well-built, and professional that just gets the job done every single time, this is the one to get.

Great product!
Bought this as a gift for a friend, and he loves it! It was a great replacement for what he had before, and was such great value! Built well, performs well, is compact, and is perfect for on-the-go use. Great replacement for carrying around multiple blocks for multiple devices. Might have to get one for myself...
