Summary

The Defender OSK-2912 operates as a 12-inch cooling unit using AC or DC power. A 6V 4.5Ah lead-acid battery provides 3 to 18 hours of operation. Under the new configuration, speed settings jump from 3 to 9 compared to the older OSK-2910 version.

Key Features

1. 9-Speed Variable Control: 1100 RPM peak speed across nine distinct settings. Matches airflow intensity to ambient heat levels.
2. AC/DC Dual Power Mode: Automatic switching between wall outlet and internal battery. Keeps air moving during frequent load shedding.
3. Overcharge Protection: Integrated circuit halts power flow at full battery capacity. Stops lead-acid cell swelling or premature degradation.
4. 0.5 Hour Timer: Mechanical shutdown toggle for 30-minute intervals. Prevents unnecessary battery drain during sleep.
5. 6 Months Warranty: Manufacturer coverage for internal component failure. Protects against motor defects or charging circuit malfunctions.

Frequently Asked Questions

Runtime varies from 3 to 18 hours based on the speed setting. High RPM usage depletes the 4.5Ah lead-acid battery quickly.

Is it AC/DC operated?

The unit functions on both direct wall power and internal battery. It automatically charges while plugged into an active power source.

How many speed settings does it have?

This model includes 9 variable speed settings for precise air control. It offers 6 more speed levels than the previous 2910 version.
