The Magna-Mat is a 3ft by 4ft mat that rolls up for storage. When unrolled and placed on the ground it absorbs the natural magnetism of the earth and through the use of a coil of wire in the Mat and a Flux Capacitor and attached Magnetron it converts the earths magnetic floatation into a 12 Volt Direct Current enough to power 10 of the new
LED lights that you retrofit to your camper or it can charge your 12 volt
battery in a period of 9 ½ hours.
