Across 10 speed settings, the Defender EMKN-2986HSR uses a 12V 4.5Ah battery for 1500 RPM airflow. Remote control inputs manage the 2.5 to 28-hour backup window during grid failures. This model swaps the previous 12-inch blade for a 16-inch diameter. Under the hood, the battery voltage doubles from 6V to 12V.
