Things to Consider When Buying a Best Portable Car Heater

When selecting a portable car heater, there are several things that you need to consider. From the voltage required to the weight and the size, we have listed some of the basic factors that you need to consider when buying a portable car heater.

1. Type

  • 12V Portable Heaters: The safest and best alternative to the factory heater are the 12V heaters which are specially made for use in the car. They usually work after drawing power from the car after plugging in the cigarette lighter socket of the car. The portable car heaters should have an inline fuse for safety and should be wired directly to the battery.
  • Residential Portable Heaters: These heaters can be used in the car, but they are not designed for enclosed and small spaces. Also, it can be fatal by causing a fire as the manual asks to keep inflammable objects far from the heater. One more issue with the residential portable heater is the required wattage.
  • Portable Propane Heaters: These heaters come with a higher risk of suffocation and fire. Therefore, they should not be used in such enclosed spaces as cars.

2. Power

Power is a crucial feature when you are considering any portable car heater. This also depends largely on the size of the car you are using. For instance, a 12V portable car heater is sufficient for small cars but does not work well for larger cars or motorhomes.

3.Weight

As you need to carry the portable heater around, the heater must be lightweight. The lightweight structure of the portable car heater will allow you to carry it easily from the car to your house and back without any fatigue. The lightweight design will also make it easy for you to store when not in use.

4. Size

Before investing in any portable car heater, you need to check its dimensions. This is a very crucial step as you need to see if the portable car heater fits easily inside the car. It will become a useless investment if the heater is not suitable to use in the car.

5. Functionality

You need to decide why you need a portable car heater. Whether you need to keep the whole car or RV warm or for the windscreen to melt the frost or a heated cushion that is capable of warming your whole body. Different portable car heaters are suited for each function, so you can choose the one you need accordingly.

6. Compatibility

You need to make sure that the 12V lighter port in your can handle the portable car heaters. These heaters mostly use the lighter port to draw the power from your car. If the lighter port is not sufficient then you will need an inverter to draw power.

Best Portable Car Heaters: FAQs

1. Are portable car heaters safe?

Ans: If the portable car heaters are used properly, they are extremely safe. For example, many 12V car heaters have an inline fuse for safety. However, residential heaters, even portable ones, are not safe for the car.

2. Do portable car heaters work well?

Ans: The portable car heaters that are charged by the cigarette lighter outlet cannot suffice for the full heating system of the vehicle while a 12V charger by a battery is more able to provide warmth with an inline fuse. A universal heater that relies on coolant is the best attendance, but they are expensive and very difficult to install.

3. Are propane heaters suitable for cars?

Ans: No, using propane heaters in the car is a very bad idea, especially with the windows closed. Along with the harmful propane exhaust, they also emit water vapour and moisture. Therefore, without proper ventilation, the oxygen levels might be reduced and pose a fire risk.

4. How to heat the car without a car heater?

Ans: You can heat the car without a car heater by carrying a blanket or keeping a hot water bottle. If you want to keep the whole car and not just yourself, you can use portable car heaters, but they are not as powerful as the air conditioning system. Further, the car can get heated up quickly if you park under the sun for long hours.

5. What kind of portable car heater is the best for your car?

Ans: This answer depends on various factors. Your car size generally decides the power that you need for the car heater.

6. Can portable car heaters be used in any vehicle, whether parked or stationary?

Ans: Certainly, portable car heaters are compatible with most vehicles equipped with a cigarette lighter socket or a suitable power source. However, it’s crucial to verify the heater’s specifications and compatibility with the specific vehicle before usage. While these heaters can be used in parked or stationary vehicles, precautions such as ensuring proper ventilation and avoiding leaving the heater unattended for an extended period should be observed. Generally, these heaters are most effective to use while driving.

7. Can a portable car heater be used when the engine is off?

Ans: Yes, you can use the heater with the engine off, particularly if it’s powered by a separate power source like a power outlet or a battery pack. Suppose the heater relies on the car’s electrical system without the engine running. In that case, it’s important to note that it may draw power from the car’s battery, potentially leading to battery drain. Therefore, it’s advisable to be mindful of the power source and the capacity of the car’s battery to ensure optimal performance and prevent any issues.

Conclusion

Portable car heaters are a good backup if your car’s main heater breaks down. They aren’t as powerful but can be helpful. Replacing a car’s heating system is costly and takes a lot of work. So, a 12V 150W portable car heater should be enough for the winter. If you’re still wondering as to what’s the best portable car heater out there, then the below final top picks are what we would recommend.
