The powerful, high volume, Endless Breeze portable 12-volt fan from Fan-tastic Vent uses an automotive type motor and twelve inch blade operating at three speeds. The air movement of up to 900 CFM (cubic feet per minute) is the equivalent of a constant 10 mph wind.
Standing only fourteen inches tall on retractable legs and less than four inches deep it travels and stores easily and weighs under five pounds. Endless Breeze can be powered by any 12-volt power source with its attached 12 volt plug and cord such as automotive lighter outlets, connecting jumpers to any 12 volt battery, or you can plug in your Endless Breeze in a *110 volt AC, 5 AMP converter.
Maximum current draw is three amps. Endless Breeze is equipped with an innovative pet friendly Swing-out Hanger Arm that allows easy attachment of the fan to the side or front of your pet crate. That allows you to cool your pet before, between and after playing fetch or while traveling. A steady breeze is also an effective method to discourage mosquitoes that don’t like flying in a breeze and to blow the bugs away on hot muggy nights.
Reviews on Amazon.com of the product are mostly favorable. Complaints are that it’s mostly plastic and flimsy. But most say it moves a lot of air and has been dependable. It sells for about $70.
