Inside is a Realtek RTL8156BG controller, an updated chip UGREEN pairs with low power draw and reduced heat so throughput stays steady during sustained transfers rather than tapering off. If your router or switch already supports 2.5Gb, this adapter upgrades an older…

Frequently Asked Questions
Will this actually give me 2.5Gb speeds on my home network?
Only if the other end supports it. The adapter tops out at 2.5Gb, but you need a 2.5Gb-capable switch or router on the other side; on a 1Gb network it falls back to Gigabit.
Does it work with a MacBook Pro or MacBook Air?
Yes. UGREEN lists MacBook Pro and MacBook Air among supported devices, along with Dell XPS, Mac Mini, iPad Pro, and iPad Air.
Can I use it with an iPhone or iPad?
UGREEN lists iPad Pro, iPad Air, and iPhone 17, 16, and 15 Pro and Pro Max as compatible, so wired Ethernet on a USB-C iPhone or iPad is supported.
What chipset is inside, and does it overheat?
It uses an updated Realtek RTL8156BG. UGREEN specifies low power consumption and reduced heat dissipation at full 2.5Gb speed for stable sustained performance.
Is it durable enough to keep in a laptop bag?
The housing is aluminum with a reinforced design, and the ports are built to resist repeated plugging and unplugging.
