TP-Link Ethernet Splitter 1 to 2, 1000 Mbps High Speed Dual-Port Internet Splitter, Compatible w/ Cat8/7/6/5e/5, USB-C & Ethernet Cables Included, Aluminum Case, Plug and Play for Routers & More EH210

It's a touch chunkier the ugreen one, but I have a little USB-powered 3 port switch "splitter" like that (although it was $15, so no pricier than the 5 port.) The advantage of it over the 5 port switch is it's like 1/4 the size and less than 1/4 the weight, and it's USB powered vs. needing its own brick. It loves with the travel router in my work travel electronic bits bag, because the GL.inet travel router (Beryl AX) only has one LAN port, and I sometimes want to be able to have both my personal laptop and work laptops wired to it.
