The Ryobi Hybrid trimmer is the trimmer that never runs out of power. Cordless and Electric. This unique trimmer is a member of the ONE+ 18-Volt tool family that means that it will work with any Ryobi 18-Volt battery. The most unique thing about the Ryobi Hybrid is the dual power source. Aside from the battery, this trimmer is also electric so you can use the battery or use an extension cord. This means you have unlimited power for jobs closer to the building and cordless mobility for jobs beyond. So whether you’re using the fade-free lithium battery or the electric port, this trimmer will never run out of power. On top of that, Ryobi packs this trimmer with convenient features like adjustable cut-width, edger capability and an outstanding 3-year warranty.
