Are you freezing in the room or office during winter??
A portable heater is like a box full of summer in the winter time. It does more than warm you and your surroundings, it helps chase away the winter blues.
Sitting comfortably at your desk, or standing confidently at the garage work bench, suddenly winter doesn’t seem so long. You’ve got heat and you’re going about your usual business with a better attitude than you would sitting or standing there with chattering teeth.
