If you're ready to invest in one of the best portable space heaters, there are a few things you should know. First, the lightest models usually weigh less than 5 pounds, making them easy to carry from room to room. They are also typically quieter than their full-size counterparts, a plus when you want to stay warm without the added noise.
But, even small space heaters have a wide range of capabilities, most importantly, how much space they can heat. In your search, you'll find some models that can heat up an entire room, while others are designed for warming up a targeted space a few feet away. As a rule, you'll need around 10 watts of power for each square foot you want to heat, so keep this in mind as you shop.
And, because space heaters can pose a hazard if not used properly (they are the second leading cause of home fires behind cooking, cites one report), you'll want to find a heater designed with safety features. Most of the options below have features like automatic shut-off and tip-over protection that are specifically designed to protect your home. Note also that even the safest space heater on the market should never be left unattended or on while you sleep at night.
With that in mind, here is a detailed look at some of the best portable space heaters to keep you warm.
