The Caframo Limited True North Space Heater is more like a standard space heater, useful in large vans and RVs. It’s mountable and takes a standard 120v AC jack so it’s easy to set up.
Unlike many portable heaters, it offers a range of temperatures instead of just two or three. It puts out enough heat to temporarily replace a broken heater, which can be a lifesaver in the right circumstances.
Don’t let the name Golf Cart Heater fool you. This heater works well in cars, especially for frozen windshields. It features an oxygen depletion system, porcelain coated reflector and a pilot wind guard. The ergonomic design fits into any standard cup holder. It delivers 4,000 British thermal units (Btus) for up to five-and-a-half hours on one propane tank.
The propane-powered Mr. Heater Buddy is an excellent choice for those who need auxiliary heat but lack access to 120v power. It can heat up to 225 square feet, more than enough for large vans and RVs.
One drawback: It should only be used where it can be securely placed. It runs off one-pound propane tanks and can be modified with an adapter for larger tanks.
Yes, portable car heaters can be an effective way to warm up your vehicle’s interior, confirms Bialaszewski. “The portable units provide targeted heat directly inside the car, helping raise in-cabin temperatures,” he explains. They are designed to supplement the built-in car heating system, especially in situations where the standard heater may not provide enough warmth, such as in very cold weather or during emergencies.
While portable car heaters are generally designed with safety features, there is still a potential risk of fire if they are not used properly. Common causes of fire hazards include overheating, electrical malfunctions or using incompatible power sources. To minimize the risk of fires, it’s crucial to follow the manufacturer’s instructions for installation and usage, including any safety guidelines provided.
Choose a portable car heater based on your vehicle’s size. According to Bialaszewski, smaller units around 1,000-1,500 watts work well for sedans and coupes; while larger 2,000+ watt heaters are ideal for SUVs, trucks and vans with more cabin space to heat. Match the heater output to your needs.
“Most portable car heaters plug into the 12V outlet/cigarette lighter port in your vehicle and draw power directly from the car battery,” says Bialaszewski. Some models offer battery power as well for flexibility. “Just be mindful of runtimes so you don’t drain your car battery,” he warns.
To heat your car without a functioning heater, use blankets, layers and hot water bottles for insulation. It’s smart to keep hand warmers and an emergency sleeping bag in your vehicle as well. Park in the sunlight for natural warmth, do light exercises to generate body heat and crack a window slightly for ventilation. In case of persistent heating issues, try these repair tips or have your car’s heater inspected by a professional.
