The 18-Volt LXT Lithium-Ion Job Site Radio (model XRM05) delivers rich sound and increased compatibility in a more compact size. It is a perfect addition to the workshop or job site. It's part of Makita's expanding 18-Volt Lithium-Ion system, the world's largest cordless tool system powered by 18V Lithium-Ion slide-style batteries. Makita 18-Volt Lithium-Ion batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger. The XRM05 is MP3 compatible for iPod and MP3 players, and delivers rich stereo sound from 2-powerful 3 in. side-firing speakers. It is engineered to stand up against harsh job site conditions with protective bumpers, and features dust and water-resistant construction for increased durability. The radio can be powered by Makita 14.4-Volt, and 18-Volt LXT Lithium-Ion batteries (all sold separately).
