Also: What is Thunderbolt, and how is it different from USB-C?

Housed in a compact aluminum case no larger than a deck of cards, the Thunderbolt 4 Hub Slim Pro packs a powerful punch. It's a fully functional Thunderbolt 4 hub that includes a 96W Power Delivery upstream host port for charging, a USB-A 3.2 Gen 2 port capable of data transfer speeds up to 10Gbps, and three downstream Thunderbolt 4 ports. These ports support up to 15W of charging power, 40Gbps data transfer rates, and video output of up to 8K to external monitors.

This hub has earned a place in my laptop bag over the past few weeks because I get pro-grade features out of a dock that before wouldn't have been portable at all. When at home or the office, this hub can drive my dual displays and a selection of USB-C devices with ease -- and it looks stylish in the process. 

Also: I turned my laptop into a desktop PC and I've never been more productive

When out and about, I find it small enough to put in my bag along with my laptop, and it replaces my need to carry a separate charger -- the 96W of power it delivers to my MacBook Pro is good enough that I can leave my 140W MacBook Pro charger at home -- and I can connect any number of accessories to my laptop. 

I have a no-compromise, professional setup that's portable and will cope with whatever I throw at it. 

It's important to note that Macs equipped with the base model M1, M2, or M3 processors support only one external monitor when connected to this hub. This limitation is crucial for users to consider when planning their workspace setup with these specific Mac models. 

Thunderbolt hubs tend to get warm during operation, especially when charging devices or transferring data. This Thunderbolt 4 Hub is no exception; it does warm up under use. However, based on my experience, the hub safely and effectively dissipates heat. The hub's specifications list standard operating temperatures as 86-122
