4 Portable Car Heaters to Have On Hand for Emergencies

Most cars generate enough heat under normal operation to keep occupants warm and defrost the windshield. However, in some locations or emergency situations, it’s just too cold for the engine to do the job. If that’s the case, be prepared with one of the best car accessories during emergencies: a portable car heater.

Buying a Portable Car Heater

When choosing the best portable car heater for you, consider:

• What size is your vehicle? A heater that’s too big will cook you in a sedan, and one not big enough won’t provide relief in an SUV.

• What do you need it for? A heater to defrost the windshield quicker can be a lot smaller than one you depend on to keep you alive.

• How is it powered? Some smaller heaters take a standard 12V car plug. Others need more wattage and require a direct line to the battery. There are also heaters that run off propane instead of electricity.

Best Portable Heater for Seats

If your car lacks heated seats, add them with the HealthMate Velour 12V Heated Seat Cushion. You’ll never again experience the sensation of being blasted with hot air while your back freezes against cold cloth or leather. This product fits most standard car seats.

Pros:

• Easily removable;
• Powered by 12V DC outlet;
• High/low/off temperature control
• Max temperature of 114 F;
• Soft and durable velour;
• Lumbar support.

Best Portable Heater for Vans or RVs

Pros:

• Mountable with a standard 120V AC jack;
• Automatic thermostat maintains selected temperature;
• Automated anti-freeze setting;
• Dual overheat protection;
• Five-year warranty.
