HP USB-C to RJ45 Adapter G2

The HP 4Z527AA is a portable USB-C to RJ45 network adapter that adds a wired Ethernet port to laptops and tablets lacking a built-in jack. It supports 1000Base-T Gigabit Ethernet over twisted-pair cabling with a 128 MB/s data transfer rate. The compact, plug-and-play design requires no external power and fits easily in a travel bag.

For mobile workers needing reliable wired access

This adapter suits professionals who need stable, low-latency connections for video calls, large file transfers or managed-network access in offices, hotels or co-working spaces. It is not for users whose devices only offer USB-A ports unless a separate USB-C hub is used. Buyers requiring multi-gigabit speeds beyond 1 Gbps or multiple simultaneous Ethernet ports should look at a docking station or desktop NIC instead.

Gigabit headroom for everyday workloads

The single 1000Base-T port comfortably handles 4K streaming, cloud backups, VPN traffic and typical office workloads without saturating the link. It runs out of headroom when aggregated throughput exceeds 1 Gbps, such as sustained multi-gigabit NAS transfers or link-aggregation scenarios. The USB-C interface and 128 MB/s rate keep latency low for responsive remote-desktop and VoIP sessions.
