Portable Wired Network Adapter

The Zebra B2B048 adds a Gigabit Ethernet port to any device with a USB 3.0 socket. It suits ultrabooks, tablets and point-of-sale terminals that ship without a built-in RJ45 connector. The adapter draws power from the USB bus and requires no external supply. Driver support is provided by the host operating system.

USB 3.0 Bandwidth Limit

The USB 3.0 interface caps real-world throughput below the theoretical 5 Gbps link speed. Protocol overhead and host-controller scheduling typically reduce sustained rates, so the adapter cannot guarantee full 1 Gbps line-rate under heavy load. Cable quality and port power delivery also affect stability on longer runs.

Single RJ45 Port Constraint

Only one Ethernet connection is available per adapter. Systems that need simultaneous wired uplinks or link aggregation must use additional adapters or a multi-port dock. The single-port design also means failover between two physical networks is not possible with this unit alone.

Questions about this item

Should I choose this B2B048 model for a USB 3.0 port?

Yes, the B2B048 is built for USB 3.0 and delivers up to 1 Gbps wired throughput on that interface.

What does the 1 Gbps rating mean when I plug it into my laptop?

It provides a full gigabit Ethernet link over USB 3.0, so large transfers and POS traffic run at wired speeds without Wi‑Fi drops.

Does the USB 3.0 connection limit the gigabit port in practice?

No, USB 3.0 bandwidth exceeds 1 Gbps, so the adapter can sustain the rated Ethernet speed without bottleneck.
