DIY 12v Space Heater (w/2 heating elements!) 150F(65C) dual fans, AC/DC power solar/batt/car options

Homemade 12v Space Heater with 2 heating elements! (for twice the power of the original!). Made using 2 12v PTC ceramic "ripple" heating elements. for on & off-grid use. Lots of ways to run it (12v battery, 12v solar panel, auto 12v power socket or AC). Temps up to 150F(65C)! smooth and quiet with a strong airflow. It's become my 'go to' desktop heater this season.
