How to Use Mini Mat in The Car?
To use the mat in the car, you need to purchase an inverter device converting 12V or 24V (depending on your car) into 110V. The continuous wattage of the converter should be at least twice more than that of the mat. For the mini mat, it should be min 200-300W.
This device Power Inverter Car Adapter should work fine if your car fuse protecting the car electric outlet has enough amperage to use the inverter.
Please make sure you do not activate the car seat heater while using your mini mat in the car to avoid overheating it.
