Staying warm can be such a hassle in the wintertime. It seems like everywhere you go, you feel uncomfortably cold. I find this to be a hassle particularly when I’m driving in my car. Everyday when I climb in my car, I crank up the heater but it takes a while to turn on. When it finally does, I’m usually close to my destination so I barely feel the heat.

When I bought a portable car heater, I felt so much better. My drives felt warmer and more comfortable. Instead of sitting in the cold waiting for the car’s heater to kick on, I had my portable car heater that warmed me up. It worked to make me feel a lot safer and more comfortable from the warm air.
