Vento Smart Fan
Description
The Vento Smart Fan helps keep your car dramatically cooler while parked. Using powerful ventilation, it continuously removes trapped hot air and replaces cabin air every 30 seconds, helping reduce interior temperatures by up to 40°F, making it a great option for mild to moderately hot weather.
Designed for everyday convenience, Vento installs in seconds with a secure suction mount and runs directly from your vehicle with built-in low-voltage protection. Just lower window, fan starts automatically.
Smart connectivity lets you monitor temperature and system status from anywhere using cellular connectivity or Bluetooth. You will also receive instant alerts if temperatures rise or power is interrupted, giving you extra peace of mind while you are away from your vehicle. An external temperature display helps others clearly see that your dog is safe and comfortable inside.
Estimated shipment in late November 2026.

Specifications
Fit and requirements
A sealed car is an oven. Vento opens a valve.
Sunlight through glass heats the air faster than the cabin can shed it. Vento's solar fan runs a constant exchange with outside air, so the cabin tracks close to ambient instead of climbing past 140°.
Check the car from the checkout line.
Vento runs on its own by default. The app is there when you want the number.
Three steps, once. Then never think about it again.
Clip it to the glass
Lower the window, seat the vent on the frame, raise the window. Nothing is drilled, taped or wired.
Plug it in
Run the cable to your 12V outlet, or to a power bank that stays in the car. Either way, one connection.
Lower your window
Auto mode reads cabin temperature and scales the fan on its own. You do not touch it again.
Plug in once. Charge while driving. Stay powered while parked.
Two setups, depending on whether your 12V outlet stays live with the engine off.
Direct vehicle power
For vehicles with an always-on 12V outlet.
Portable battery, left connected
For vehicles where the 12V outlet turns off with the ignition. The battery stays in the car, wired between the outlet and Vento.
The battery never has to come inside. Leave it plugged into both ends and it tops itself up on every drive.
You've already tried the other four things.
A number anyone walking past can read.
The outward-facing display shows live cabin temperature and fan state, so a passerby can tell at a glance the car is actively ventilated.
TESTED BY REAL OWNERS
Questions before you preorder.
Is Vento an air conditioner?
No. Vento increases airflow and replaces the cabin air roughly every 30 seconds. It cannot cool below the outside temperature and it cannot guarantee a safe cabin temperature under all conditions.
How do I know if my 12V socket stays live when parked?
Turn the vehicle off, plug the included cable into the cigarette lighter socket, and check the LED on the power plug. If it stays lit, your socket is always live. If not, use an external battery or power station, or switch the vehicle to an accessory mode that powers the socket.
Do I have to lower more than one window?
Yes. Lower the window with Vento installed and at least one window on the opposite side of the vehicle about 5 inches (13 cm), so air can move through the cabin and the vent flap can open completely.
How do I stop the fan?
Raise the window with Vento installed until it is fully closed. The vent flap closes automatically and the fan stops. You may need to slide the unit slightly forward or backward so the flap moves freely.
Does remote monitoring work when the window is closed?
No. Remote temperature monitoring and alerts are active only while the window is lowered and Vento is operating. With the window fully closed and the fan stopped, monitoring and alerts are disabled.
Will it drain my car battery?
Vento has built-in low-voltage protection and stops drawing power before the vehicle battery reaches a level that would prevent starting.
When does it ship?
This is a preorder. Estimated shipment is late November 2026, and you have 30 days from delivery to return it for any reason.
