A portable automated vent cover includes a drive system, a telescoping tube, a vent cover plate and a collapsible mobile tripod. The drive system preferably includes a drive motor, a gear box, an up-relay and a down-relay. The telescoping tube includes an outer support tube, an inner cover tube and a rack gear. The rack gear is attached to the inner cover tube. The vent cover plate is secured to a top of the inner cover tube. The drive motor drives a pinion gear through the gear box.

Electrical power is controlled by either the up-down switch or a controller and sent to the drive motor through either the up-relay or the down-relay. The collapsible mobile tripod is attached to a bottom of the outer support tube.
