Benefits of Stand-Alone Automobile Heaters

When winter is coming, it is time to make sure that your vehicle is in the proper condition. It is time to check the tire pressure, change the coolant, and have your winter oil changed. You also need to test your heater to make certain that it is working too. Car heaters are one of the elements that can fail over the summer. If this happens, it could cost you from $300 to over $1,000 to fix, depending on the model and the problem. Besides, some luxury model vehicles come with seat warmers, but this can cost you thousands. You can purchase a heated seat cushion for a much lower amount and get the same benefit. Let’s take a look at some of the top stand-alone heaters available.

Things to Watch Out for in Automobile Heaters

A heater is a simple device. A heating element of some type either heats up the seat itself or heats air and blows it into the cabin with a fan. However, there are some things that you want to consider when choosing one.

  • Automatic Off Timer. This is something that you will not think about until the unfortunate occurs. Regardless of the type of warmer that you choose, make sure that it has an automatic timer to turn it off. Otherwise, you can forget to turn the warmer off, and it will drain the battery.
  • Power Source. Make certain that the warmer plugs into a 12V battery and will work with your vehicle. Most warmers manufactured in the United States will be the correct voltage. Some are made for RVs, semi-trucks, golf carts, or boats, and they might have a different power rating, so be sure to check this.
  • Automatic Temperature. Make sure that the warmer you choose has an automatic temperature control that allows you to set the temperature. Otherwise, you will have to keep adjusting it continues to stay comfortable.
  • Quick Warm-Up. Find out how long it takes the unit to warm up. You don’t want to have to wait for the seat to warm up too long on cold days.
  • Universal Fit. If you buy a seat cushion heater, make sure that it has a universal fit. Some of them are only made for certain makes and auto models. You also need to check that the straps are strong and will keep the cushion securely in place.

Technical Terms

A stand-alone heater is a simple item, but you still might encounter some terms while you are shopping that you might not know.

BTUs. This stands for British Thermal Units. This is a term that describes the amount of heat the unit puts out. One BTU is the amount of heat that it takes to raise one pound of water by one degree Fahrenheit. The more BTUs, the better the heating element in the unit. This can have an effect on how quickly it warms up and the highest temperature that it will reach.

Massage. Some seat warmer cushions have massagers. These are little spheres that move around and give you a back massage to relieve tension. Some also have a vibrating massage.

Maximum Temperature. The maximum temperature is the highest the heater will go. For safety, you should never buy a cushion that warms to a temperature above 140 degrees Fahrenheit.

Types of Stand-Alone Heaters

There are several different types of stand-alone heaters, and they all serve different purposes. Here are the most common types.

Window Defrosters. They are small heaters that sit securely on your dashboard. They usually do not heat very high and are only meant to defrost the windshield. They cannot be expected to do a good job of warming the entire cabin.

Seat Cushion Heater scheme
  • Seat Cushion Heaters. Seat heaters stand for a pad that fits over your regular seat. The heat in a similar way to an electric blanket to keep your back warm. Some of them have massagers too. They do not do much for warming the entire cabin temperature of the car, but they will provide some radiant heat. They deliver the heat to where it is needed the most. They work similarly to heated seats that come in luxury vehicles.
  • Back Seat Heaters. These heaters work similarly as any home heater that you use to heat a room. They are usually small and can be placed in the front or back seat. This is an excellent option if you have a heater that is not powerful enough the keep rear-seat passengers warm.

Here are some of the most Frequently Asked Questions about automobile heaters.

Are stand-alone automobile heaters safe?

For the most part, stand-alone heaters are safe when used properly, and some common safety precautions are taken. For instance, make sure that the heater is sitting level and in a place where it cannot be knocked over or have beverages spilled on the warmer. Also ensure to keep flammables, like paper, away from them. On some units, the surface can become very hot, so make sure to use caution around children.

How big of heater do you need?

The size and type of heater that you choose will depend on the size of your vehicle and your needs. For instance, if you travel with someone in the back seat, you will want a warmer that is large enough to provide them comfort too.

What is the power source?

The majority of heaters come with a plug that you insert into your cigarette lighter. Some are battery-powered, and others use a tiny container of propane as the heat source.

Will it drain the battery if left on?

If you have an electric heater that plugs into the cigarette lighter, it pulls power directly from the battery. If you forget to turn it off, it is the same as leaving your headlights on. Make sure to choose one that has a timer that will shut the unit off after 30-90 minutes, in case you forget.

Our Best Choice

This review gives you many great choices when it comes to an alternative heat source for your car. Out of all of them, we like the SNAILAX massage seat cushion. It was the most comfortable, heated quickly, and the massage feels great. You would pay thousands of extra dollars for a massaging, heating, and a cooling seat on a new automobile. This is an excellent alternative.


Whether you need a stand-alone heater because yours is broken, or because you simply want the comfort of a heated seat, the most important factor is finding the one that suits your needs best. The least expensive is not always the best choice. When it comes to alternative heating sources for your vehicle, the options in this review are all less expensive than repairs or the cost of these amenities in a new automobile.
