Amazon.com Product Description:
The Whistler PP300AC 300-watt power inverter provides electrical power from your car, truck, recreational vehicle, boat, or any other deep-cycle battery source. Just plug it into the cigarette lighter to convert 12-volt power to household AC power and run business and household appliances far from the nearest electrical source. This 300-watt inverter is good for use with radar detectors, laptops, and small TVs. It can recharge batteries for laptops, cell phones, and camcorders. The automatic shutdown feature will warn you when the battery is getting low, then shut down before draining the battery, so you can start your vehicle.

Be sure to check the wattage requirements for the appliance you want to use before selecting a power inverter.

Rating : - makes too much noise
I just used this item today for the first time. The fan makes so much noise you would not use it in your car. It would be very annoying. I plan on returning it as soon as i can.
