Review of the Best 12-volt car heater

1. Review of RoadPro RPSL-681 Direct Hook-Up Ceramic Heater

We are starting our review with one of the most unique car heaters out there. It is made especially for heating trucks and it is one of the biggest heaters available right now.

So, it is perfect for heating up any pickups, tractors or trucks. Remember that you need to connect it to the car battery directly to power it up. 

It would be a great solution for expedition trucks too, if that’s your choice of vehicle for overlanding.

It is a 12 V heater which needs at least 25 amp in-line fuse. It is advised that you should install this heater in a suspended position.

So, you should not place it on the dashboard or the floor of your vehicle. However, as it comes with a 15 feet cable, you will be able to install it with ease following the instruction manual.

All the required hardware to install it comes in the package. It is pretty intuitive to use it.

There is a switch to turn it on or off. Added to that, you will find a dial to control the level of the heat inside your vehicle easily.

So, if you need to cool the temperature down a bit or vice versa, you can do that. There is also a swivel base at the bottom of the heater. So, you can set up the direction of the air flow to your liking without any issues.

What Previous Buyers Said?

One particular buyer said that he bought this heater for his dad’s pickup - and it is working perfectly. Another buyer said that she bought it for heating up their truck cabin.

She installed it effortlessly and it heats up the vehicle in minutes. Most of the buyers were happy with it.


  • Emits hot air immediately
  • Can heat up large areas adequately
  • Comes with a robust build quality


  • Some might face difficulties to install it as it needs to be hooked up directly to the battery

2. Review of Cabin Heater AH-200

This one comes from the famous Aqua-Hot brand. Aqua-Hot is one of the industry leaders in the RV heating industry.

They are well known for offering car/RV heaters of top quality. This particular car heater is not any exception at all.

It comes with some useful features which can come in handy to keep you warm.

For instance, it has a max of 6000 BTUs/hour. This heater has a fan output of 200 CFM. All these means, this can heat up a small cabin efficiently.

Additionally, it heats up so fast and doesn’t take a lot of space as well. Due to its compact size, it can be used as a portable car heater as well.

The installation process is easy. It comes with a mounting bracket which can be rotated up to 180-degrees. 

You can also lock the rotation. There is a switch which can be used to turn it on or off. Also, you can increase/decrease the level of heat with that switch as well.

This is a water-based 12V DC heating system. From our observation, we can tell you that, it will be a perfect choice for side-by-side UTVs, and any other small cabin compartment vehicles.

What Previous Buyers Said?

The majority of the previous customers praised the efficacy of this car heater. In fact, some of them also stated that it is one of the best 12-volt car heaters for ATVs and UTVs.

  • The temperature level can be controlled


  • When the fan is at 100%, there might be a bit of noise

3. Review of RoadPro RPSL-581

RoadPro is behind some of the best 12 Volt car heaters. However, in the case of the RoadPro RPSL-581, they may have done a poor job. It’s true that this is a feature-rich defroster, but it's just not car heater.

The manufacturer did not design this product to heat a car, only to defrost your windscreen apparently, but people are trying to purchase it as a heater. Big mistake.

But, the problem with this heater is that it can’t carry out the task of keeping the vehicle warm. And, that is why we don't recommend it to our readers.

We have included this one on our review of the best 12 Volt car heaters so that you can avoid spending money on it.

What Previous Buyers Said?

In short, almost all of the buyers were disappointed with it. Some said this is a waste of money while others said this was one of the worst purchases of their life..

So, you can see that it is far from the best 12 Volt car heater. So, if you are not short on budget, there are other great options out there for you.


  • Offers various features for a portable car heater
  • The price is not that high


  • Can’t produce enough heat even for a small cabin
  • Installation is cumbersome
  • It cannot defrost the windows as well

4. Review of Peak PKCOJ5 12V Heater and Fan/Defroster

This is another portable car heater which comes with lots of features. Yet, this one has plenty of drawbacks that it should not be on your wish list.

This 12 Volt car heater can be powered with a cigarette lighter plug. 

It has a foldable handle for adjusting the position freely. And on the back, there is a 360-degree rotary holder with which it can be mounted with ease.

However, this one also has the same drawback as the last one we talked about. It doesn’t produce enough heat to keep you warm in the cold temperature.

Again, don't buy it to use it as a heater because it can't do the job.

What Previous Buyers Said?

The overall feedback of the previous buyers about this car heater was negative. One buyer said it produces barely any heat at all.

Another person reported that it stopped working after a month. And, another customer told that it blew out the fuse on his lighter. So, we would tell you to keep away from this car heater.

  • The design is attractive
  • Great build quality


  • Can’t produce enough heat
  • Users are usually unhappy with this product

Types of Car Heaters

Mainly, there are 3 types of car heaters. They are fan-forced car heaters, convection car heaters, and radiant car heaters respectively. Let’s elaborate…

Fan-Forced Car Heaters

This is the most common car heaters you will see. Matter of fact, almost all of the car heaters we have talked about in this post are of this kind.

This type of heaters actually works like a typical fan. It will take the normal air from the environment and will pass it through a heating element.

As a result, the cold air will be turned into hot air. And, the fan will circulate the hot air into the room. This tends to be cheap and easy to operate.

On the other hand, the fan might make a tad bit of noise while blowing the air out at the high setting.

Convection Car Heaters

As the name suggests, this type of car heaters uses the convection method to heat up your car. It will convert the cold air to hot air of the surroundings.

During that period, the hot air will rise up and will create a void for more cold air to enter. Over time, the cold air will turn into hot air and the environment will be filled up by hot air.

If your vehicle is sealed up, then it will be wiser to use convection car heaters. Also, as this type of heater completes a cycle over and over to generate hot air, it will take a lot of time to heat up your vehicle using this type of car heaters.

And, that is one of the main reasons, we haven't included them in this review of the best 12-volt car heaters.

Radiant Car Heaters

This type of car heaters uses infrared radiation to heat up the air. It will heat up the area where the infrared radiation will hit.

Due to this process, it is better to use this heaters to warm up any specific object. So, it is not a good idea to use radiant car heaters to keep a big area warm.
