This looks like a possible alternative to the Endless Breeze. Cheaper but at 12" in diameter should shift a similar amount of air. But it only comes with crocodile clips for 12 volts so you would probably want to add a suitable 12 volt plug. The reviews are a bit misleading as they mostly refer to another version sold with a solar panel.
