## Overview
The DESOFICON USB C Ethernet Adapter is a compact 2-in-1 accessory that adds a wired RJ45 network port and a USB-C pass-through charging port to any USB-C device. Supporting 10/100 Mbps Ethernet, it’s designed for users who need a stable internet connection without relying on Wi-Fi. Weighing just 20 grams, it’s easy to carry in a pocket or laptop bag. Compatibility extends across a wide range of USB-C devices: iPhone 15 series, iPad Pro (2018 and later), Samsung Galaxy S and Note series, Google Pixel, OnePlus, and many laptops. No driver installation is required — just plug in and the adapter is immediately recognized.

## Connectivity & Compatibility

## Product Info
It sits in the entry-to-mid range for USB-C network adapters. The 2-in-1 design — combining Ethernet and charging in one compact body — offers decent value for casual users, though it lacks higher-speed (1 Gbps) support and fast-charging PD ratings. Warranty details are not explicitly stated; returns are handled via ’s standard policy. The package includes only the adapter itself.

## Best Use Cases
iPhone 15 users tired of slow Wi-Fi: Directly plug into your iPhone 15 for a wired connection during streaming, gaming, or video calls. The pass-through charging port ensures your phone stays powered. Travelers and remote workers: In hotel rooms with Ethernet jacks, this adapter provides a more stable connection than shared Wi-Fi. Small size makes it easy to stash in a bag. * Mobile streamers or live content creators: Reduce latency and packet loss by switching from Wi-Fi to wired Ethernet. The 100 Mbps limit is sufficient for most streaming services. Not recommended for: users with gigabit internet plans who need full-speed wired performance, or those requiring USB-C Power Delivery above 15W for laptops. In those cases, look for a USB-C to 2.5GbE adapter with PD 60W+ support.
