Giochem B-3 Lightning Ethernet Adapter

The Giochem B-3 is a wired network adapter that connects iPhone and iPad models to an RJ45 Ethernet cable through a Lightning port. It draws power directly from the host device and requires no external supply or driver installation. The 3.3 ft cable links the adapter to the network port for a stable wired connection.

Suited for iOS users needing reliable wired internet

This adapter serves owners of compatible iPhone and iPad models running iOS 10.0 through iOS 15 who want a wired alternative to Wi-Fi. It is not for devices that use USB-C instead of Lightning, nor for Android phones, Windows tablets or laptops that lack a Lightning port. Buyers needing gigabit speeds or Power over Ethernet support should look elsewhere.

10/100 Mbps throughput for everyday tasks

The link operates at 10 Mbps or 100 Mbps, which comfortably handles web browsing, email, video streaming and video calls on supported iOS devices. It runs out of headroom for large local file transfers, high-bitrate 4K streaming or server-grade workloads that demand gigabit bandwidth. The 25 g weight and short cable keep the kit portable for travel or office use.
