Useful car fan features
- Oscillation - the fan oscillates from side to side. Ensures air circulation in a larger space.
- Heating - works faster than the car heating, so it speeds up defrosting and defogging of the windscreen in winter.
- Speed ??settings - some models allow you to regulate the airflow (typically two speed settings).
Mounting and power supply
Most fans include mounting holes for screws. If you do not want to have holes in your dashboard, you can use a strong double-sided tape. When it comes to power supply, car fans get their power from the car cigarette lighter receptacle. 12V models are deisgned for normal personal vehicles, 24V models are for trucks and some vans.
