Power adapter Lenovo 15W with DC-in and RJ45 Ethernet port 04X4337

The Lenovo 15W power adapter with DC-in connector and integrated RJ45 Ethernet port is a compact solution that combines power delivery and wired network connectivity in a single unit. It is designed to supply stable 15W power to compatible Lenovo devices while offering a built-in Ethernet interface for reliable LAN connections. The adapter reduces the need for separate network dongles and power bricks in constrained workspaces.

Advantages

This adapter integrates power and network functionality into a single compact module, saving desk space and minimizing cable clutter. The built-in RJ45 port provides a stable wired connection that can be faster and more consistent than wireless alternatives, particularly in office environments or locations with congested Wi‑Fi. The 15W output is suitable for low‑power Lenovo devices and peripherals, and the DC‑in connection ensures a direct, reliable power supply.

Suitable for

• Compact laptops and thin clients that accept a 15W DC input
• Office workstations where a stable wired Ethernet connection is preferred
• Remote or hybrid work setups with limited desk space and fewer adapters
• Environments requiring a simple, combined power and LAN solution for travel or hot‑desking

Key specifications

• Output power: 15 watts
• Power connection type: DC‑in connector
• Network interface: integrated RJ45 Ethernet port (10/100 Mbps typical for similar adapters; check device compatibility)
• Form factor: compact adapter combining power and network functions
• Compatibility: designed for use with compatible Lenovo devices that accept the adapter's power and network interfaces

How to use

Connect the adapter to a compatible Lenovo device using the DC‑in connector, then plug the adapter into a suitable power source. Use a standard Ethernet cable to connect the RJ45 port on the adapter to a router, switch, or wall Ethernet outlet. Confirm that the connected device recognizes the wired network interface in its operating system network settings. If required, install any vendor‑provided drivers or updates to enable full Ethernet functionality.

Usage recommendations

Use the adapter on a stable surface and avoid exposing it to liquids or extreme temperatures. Verify device compatibility before use and keep firmware or driver software up to date to ensure reliable Ethernet performance. For secure connections, use managed network equipment and standard network security practices.
