DM18RL Battery Adapter — Dewalt 20V Max to Ryobi 18V, USB 5V 2.1A

Extend your tools’ runtime with a practical, simpler setup

The DM18RL Battery Adapter bridges Dewalt 20V MAX XR lithium packs to Ryobi 18V ONE+ tools. Built with a lightweight yet sturdy ABS shell, this adapter helps you repurpose existing batteries on the job site or in the workshop without adding bulky chargers. It’s a smart, no-nonsense solution for keeping tools running when you’re short on power options, all while maintaining a compact footprint that travels well between projects.

What it is and what it does

Designed to convert compatible Dewalt 20V Li‑ion cells into an 18V platform for Ryobi 18V tools, the DM18RL also features a built‑in USB output. This means you can power a small device while you work, though it does not charge the tool battery itself. The adapter supports a range of Dewalt 20V MAX XR batteries and Ryobi 18V ONE+ batteries, giving you flexible options on site or in the shed.

• USB Output: DC 5V 2.1A (max) for charging phones, tablets, or other small devices
• Versatile compatibility: works with Dewalt 20V MAX XR packs and Ryobi 18V ONE+ tools

Real‑world use cases and benefits

Imagine you have Dewalt cells but primarily use Ryobi 18V tools on the project. The DM18RL helps you maximize those existing batteries, potentially extending run‑time on your Ryobi tools without investing in new packs. Its simple design keeps installation straightforward, while the rugged ABS construction adds a layer of durability for busy workdays. This adapter aims to support your workflow by offering flexibility rather than promising results, so you can evaluate it as a practical option for your toolkit.

• Extended runtime on your Ryobi 18V tools using your current Li‑ion packs
• Compact, durable design that’s easy to handle on site
• Simple to install or remove between tasks
