One reason I chose Omnidesk specifically was because of the Powerclamp. I use the HDMI input a lot with older laptops, so I don't need to dig around behind my monitor any more. Same for the network cable, which I used when doing backups to the network.
I bought a Pixel 6 phone, and if you use the included Google cable, it charges the phone. It's only 15W (Google charger is 30W), so it's not a super fast charge, but does the job in about 2 hours for my new phone. Older USB C cables won't work.
