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.
