Review on 🔋 Powerful 12V Car Fans: Cooling Air Fan with Cigarette Lighter - Low Noise, 360° Rotatable for Truck, Boat, Van, SUV, RV by Kelly Jones

Update: crash after 4 months. They started to wear out, making noise and wiggling fast, and one side failed first before the other failed! 24/7 job in Vegas, hot weather for a month, airflow in my parked van with the windows open in the yard! It bakes in the sun and I rarely use it so I set up 2 sets and leave the windows ajar to let the sun's energy flow. The front one comes in handy when I go outside with the AC on. Minus one star because they're starting to make an off-center rotational balance noise that might bother some. They're working there now, I think it's actually more than a month 24/7.
