Powered by a 58-Volt, 5.2Ah, lithium-ion rechargeable battery, the all-new Jonsered backpack blower is capable of incredible high-velocity air speeds up to 150 MPH and airflow up to 750 CFM to easily handle the toughest blowing tasks like clearing wet, heavy leaves, grass, and other stubborn debris. The battery-powered, brushless motor provides the power, performance, and runtime typical of traditional gas-powered equipment — without the hassle of mixing and storing fuel or harmful emissions. With a built-in battery power meter, it's easy to monitor power usage, and the handle-mounted, easy-to-view battery power indicator guarantees you'll never run out of power mid-task. Other impressive features include instant push-button starting with no pull cord, variable speed control, digital cruise control, and integrated power boost technology. It has an ambidextrous design that works for left- or right-handed users, and also features a heavy-duty frame; contoured, adjustable shoulder straps; and padded, load-reducing harness for optimal fit, superior comfort, minimal strain, and reduced fatigue for users of any size. Powerful, comfortable, versatile, easy-to-use, and super-quiet, it's ideal for year-round clean-up for homeowners and small business owners with 1/2-acre yards and larger.
