100W is a meaningful Power Delivery threshold, enough to charge most laptops including a 13-15in MacBook Pro under normal use, but the adapter's rated input isn't automatically what reaches your host device after the adapter's own power consumption.
We specifically compared this 100W tier against Cable Matters' and Cable Matters' own 140W models, since the wattage difference only matters if you're charging a high-draw device like a 16-inch MacBook Pro under sustained heavy load.

How We Chose These USB-C Ethernet Adapters With 100W Charging
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 a USB-C Ethernet Adapter With 100W Charging
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 a USB-C Ethernet Adapter With 100W Charging
For most laptops and all phones/tablets, 100W is more than sufficient. Only step up to 140W if you specifically own a high-draw laptop like a 16-inch MacBook Pro doing sustained heavy work.
Frequently Asked Questions
Will 100W charging work with my phone?
Yes, but your phone won't draw anywhere near 100W, that's a laptop-class charging ceiling. Phones typically charge at 20-45W even with a 100W-capable adapter, since the phone itself negotiates the actual rate.
Does the 100W rating include power for the Ethernet function itself?
On single-purpose Ethernet-plus-charging adapters like Belkin's and uni's, no meaningful wattage is documented as reserved. On multiport hubs like UGREEN's Revodok, 15W of the 100W input is explicitly reserved for hub operation, delivering up to 85W to your device.
