Not all vehicles have multizone air conditioning systems that help people and/or pets stay comfortable when they’re seated in the back. That’s where the dual-head Auto Cooling Fan from Zone Tech could help. Attached to the front-seat headrest supports or any flat surface using the supplied 3M adhesive tape, the unit’s two adjustable two-speed fans can be individually rotated in any direction and at just the right angle to supply a cooling breeze in summer, or warm air in winter (when the car’s ventilation system is on the heat setting, of course). The eight-foot-long cord plugs into the vehicle’s 12-volt receptacle. Purchase the Auto Cooling Fan for about $20 from
