Need more USB-C ports AND passthrough power?
Style: 4-in-1 USB-C Hub
This hub is very handy if you need to use multiple USB-C peripherals but still need passthrough power for your laptop, 65 watts in my case. I have not experienced any noticeable difference in transfer speeds or heat. Typical Belkin high quality, all the ports are tight and connections feel secure.
I want to note that this unit will NOT allow HDMI functions via USB-C. I still need to plug my external display directly into the other USB-C port on my laptop.
The only downside is that the surface of the hub is a high gloss black, which will scuff like crazy the first time you toss it into your backpack or set it on the table. Does not at all effect functionality but can be annoying for some. Otherwise, this is now one of my essential daily tech accessories.

Reduced Connecting To Desk Setup from four plugins to one.
Style: 8-in-1 USB-C Hub
Works great! Plugged in Ethernet, HDMI, USB-C power, and a USB-A Hub containing KBD,Mouse, two phone chargers, and worked first try without any configuring. Now only one plug to connect when the laptop is brought to the desk. Perfect!

Lots of slots to power devices all at once
Style: 7-in-1 USB-C Hub
Well made, good price, outlets precision sized so cords don't droop or fall out. Overall about as a compact as it could be. Enough power to plug into iPad and power phone, hearing aid charging box , and AA battery 4 slot charger.
Worth paying a little more for more slots.

Be aware of bad units being sold right now.
Style: 4-in-1 USB-C Hub
These USED to be a 5 star product from me, I've lost count how many I have purchased and included built into my products I manufacture. All of 2025 NO ISSUES at all, battle tested in the photo event industry buy some very large companies I have as clients. Come 2026 and the last two batch orders I have purchased I have had to replace 10 of them within a 2 month window, all for different customers because they stopped working in a short amount of time. Something happened in the Belkin manufacturing of these hubs in the past 3 months and I have lost my confidence in the stock that is available right now, I have moved to another HUB manufacturer for my products. I even tried calling Belkin quietly to make them aware of this issue and could not get anyone who cared that they had bad units being sold. So now it's to be very public about this issue and to let people know to be aware there ARE bad units in circulation of these hubs. ALWAYS have a backup on hand just in case! Sorry Belkin, you need to have a better process to receive feedback from other manufacturers that use your products in theirs. I hope I can regain confidence again someday.

Nice portable USB hub.
Style: 4-in-1 USB-C Hub
Nice little hub - output is 40 w though so a slow charger if using it to charge a phone off of a computer.
