We should be upfront about this one: HP's current standalone USB-C Ethernet adapter catalog verified through Amazon's product data is limited to a single confirmed model, HP's official G2 Gigabit adapter.
Rather than pad this list with unverifiable products, we're covering the one HP adapter we could confirm. If you want more current options at similar business-grade quality, our Lenovo and Dell OEM adapter guides, or the broader Gigabit Ethernet Adapters guide, offer deeper product pools.

How We Chose These HP USB-C Ethernet Adapters
Each pick was assessed across 5 criteria weighted for real-world use.
- 5G/5G/10G) and, where published, the specific Realtek, Marvell, or other controller chip driving it, rather than assuming USB-C connector shape implies a speed tier.
- 2 Gen 2 vs Thunderbolt/USB4) and confirmed OS support, since several products in this cluster have real exclusions (Android, Nintendo Switch, older Apple silicon).
- Favored listings that publish honest real-world throughput or explicit host-speed caveats over ones that only quote the theoretical link rate.
- Weighed braided cable construction, aluminum housing, and reinforced connectors, since these adapters see frequent plug/unplug cycles in daily use.
- Prioritized real differences like Wake-on-LAN, PXE boot, PD passthrough wattage, and multiport expansion over marketing language that repeats across nearly identical adapters.
What to Look for in an HP USB-C Ethernet Adapter
Key buying criteria so you get the right fit the first time.
USB-C is a connector, not a speed
A USB-C port can carry anywhere from 1Gbps to 10Gbps of Ethernet depending on the adapter's chipset and your host's actual USB generation. Check the exact Ethernet speed and required USB mode before assuming any USB-C adapter matches your needs.
Multi-gig speeds need a fast enough USB port
0 (5Gbps) port will not reach its rated Ethernet speed. 2 Gen 2 (10Gbps) port or Thunderbolt/USB4 host.
Check OS and driver requirements before buying
Most Gigabit adapters are driver-free on Windows, macOS, and ChromeOS, but multi-gig adapters often need a manufacturer driver on Windows or specific Linux kernel versions, and some models exclude older Apple silicon chips entirely.
Confirm your specific device isn't excluded
Several adapters in this cluster explicitly do not work with Nintendo Switch, Android, or specific Mac chip generations. Read the compatibility list carefully rather than assuming a USB-C connector guarantees your device will work.
A CAT6 cable matters as much as the adapter
Even a genuine Gigabit-capable adapter will fall back to slower speeds over an old CAT5 cable. Use CAT6 or better for Gigabit, and CAT6A for 5G/10G speeds, to actually realize the adapter's rated performance.
PD passthrough wattage isn't automatically usable
An adapter rated for 100W or 140W Power Delivery passthrough only delivers that much power if you also supply a charger and cable rated for it. The adapter's rating is a ceiling, not a guarantee, without the matching charger.
How to Choose an HP USB-C Ethernet Adapter
A Note on This Brand's Product Pool
HP's G2 adapter is a genuine first-party business accessory with a standard 1000Base-T Gigabit rating, but the retail listing itself publishes minimal detail on drivers, PXE support, or extended compatibility beyond basic port classification.
If you need explicit PXE Boot or Wake-on-LAN documentation for an HP business deployment, verify directly with HP's own support and driver pages before purchasing, or consider Dell's PXE-documented alternative.
Frequently Asked Questions
Why does HP only have one verified USB-C Ethernet adapter on Amazon?
HP's broader accessory catalog includes more networking products through its direct enterprise channel, but Amazon's currently accessible product data for HP-branded standalone USB-C Ethernet adapters is limited to this one confirmed G2 model.
