The Best Portable Car Heaters
While it may not be a conventional portable heater that you may be used to, the HealthMate Velour 12V Heated Seat Cushion is portable and has heating capabilities. The heating may be more direct than standard car heaters in that it heats your back and bottom at the same time. If your vehicle doesn’t have heated seats, this cushion is a simple and rather inexpensive fix to warming up your body quickly. It’s lightweight as well and can be brought along with you easily as it can be folded up and carried from car to car.
The seat cushion has a maximum heating temperature of 114 degrees and three control settings so you can set it to your preferred temperature. It’s a universal device as well that is built to function in cars, trucks, SUVs, and even boats. However, the cushion may take some time to fully heat up. A few minutes ought to do it though. You will also have to deal with power cords running through the vehicle to the cigarette lighter. This can be annoying to tiptoe over and can pose a tripping hazard.

The Tseipoaoi 12V Diesel Heater is an innovative diesel-powered heater that’s designed to be permanently installed in your van, car, truck, boat, or even a bus or RV. It has a high thermal conversion rate, so it packs a punch when it comes to how much air it puts out. It features an easy-to-read LCD control that measures heat in Fahrenheit, remote control operation, and a 10-liter diesel tank. Installation accessories and instructions are included as well.
Plus, it can be used to defog the car’s windows or mirrors if it’s cold, raining, or snowing. The heater is also economical, ergonomic, and easy to install. Oil quantity, temperature, and wind speed can all be easily controlled via the included remote. You can also choose to preheat your engine’s coolant to help minimize engine wear and tear in frigid temperatures. The downside of this fan is that even though it is fairly straightforward to install, it’s still much more complicated and less portable than a simple 12-volt plug-and-play heater, although it can be switched out from one vehicle to the next. It’s also quite pricey compared to some of our other recommendations.

The KVW Portable Electronic Car Heater is an ideal compact and easy to use choice for those looking to stay warm in their vehicles. It’s a multifunctional machine that is designed to be universal, so it works with small compact cars and even heats up larger buses or minivans, as long as you have a functioning 12-volt power supply in your vehicle. It’s capable of producing up to 150 watts and is made out of durable ABS plastic. It’s great for defrosting or demisting your windows and windshield, but a simple flip of the switch allows you to use it as a cooling fan as well.
However, its best features are its three main air outlets. The air is split between the three openings to better disperse the heat. This provides a much wider range, so you and the car heat up more efficiently. It’s rated to completely heat a car in around one minute, but larger cars may vary. It features a built-in fuse with an automatic safety shut-off and 360-degree rotating support. As an added bonus, it isn’t priced too high and is set at a comfortable budget-friendly price range. However, it is smaller than you would think and may take a while to properly heat up once you turn it on.

Plus, it can even be hung from the ceiling or a handle as well.
It’s a universal mounted heater that connects directly to the battery for maximum output and efficiency. However, while it may not be the most expensive portable heater, it’s not cheap. It’s priced somewhere in the middle. Another thing is it just doesn’t seem to put out all that much heat. It does get warmer but is anything but hot.

You can also disable the automatic shut-off feature if you want continuous warmth on longer rides. The automatic thermostat ensures that you feel a constant, unfluctuating temperature. There is some complaint about the length of the cord on the temperature controller being too short and the buttons being very small, making it difficult to control, but overall, this seat cushion is a great product for the price.

Plus, it’s built with advanced anti-overheating technology so it shuts down if it gets too hot (158-degrees Fahrenheit or 70-degrees Celsius). It will even start again once it cools down.
The tech goes further by preventing it from breaching 286-degrees Fahrenheit. However, the one thing we don’t like about this specific heater is its price. For its size, it seems expensive, but you can’t beat the heat it produces. Also, it can get rather hot and should not be left nearby anything that can catch fire.

Best Portable Car Heater Buying Guide & FAQ
There are lots of different car heaters out there and not all of them will be suitable for your car because not all products are made equally. You will find that some heaters have been specially designed for the inside of your car whereas others are more suited to larger vehicles such as RVs. Below we look at the features you should look for when purchasing a car heater and talk about why we really need them. We’ll look at how you can maintain your car heater if you already own one and look at all the ways in which you can keep warm inside your car during winter.

Features to Look for in a Portable Car Heater
What should you look for when buying a car heater?
You’ll need to have a good think about why you need a car heater before purchasing one. The reason for this is so that you purchase the right type and not something totally unsuitable and unsafe for your vehicle. Do you need a heater to help defog your windscreen during the colder months or are you looking for something that will keep you warm? Do you own a car or an RV? The size of your vehicle will have an impact on the size of the heater that you purchase and also the type. Write down a list of reasons why you want to purchase and keep this handy when you go shopping. Heaters that are designed for backseat passengers are often very different from those designed for icy car windows.
So you’ve found the perfect car heater and you’re ready to purchase – perfect! Problem is the voltage doesn’t match the voltage from your car. Don’t make this mistake! Check to see how the car heater is powered – is it from the cigarette socket or is it powered a different way? Checking to see that it is compatible with your vehicle is one of the most basic things you can do.
Some larger, more powerful heaters are unsuitable for cars and vice versa. Make sure that you have an idea of what you want the heater for and if it’s a larger vehicle then jot down the size of the area that you would like heated. Often, larger heaters will inform you how much square footage the heat can cover.
The efficiency percentage will give you a good idea how much heat from your portable car heater will be utilized and not wasted. As you won’t be using a flame heater you will find that most heaters are pretty efficient but do have a look to make sure that the percentage is at least 95% or above.
When using a portable heater in such close quarters it’s absolutely vital that you check the safety features. Look for Oxygen Depletion Sensors (ODS) as well as accidental tip-over safety shut offs for added safety.
Do you simply just plug the heater in and switch it on or do you need installation hardware to fix it into your vehicle? How confident are you doing this and do you have the right tools and equipment or are they included? Check, check check!
If you’re looking for a super budget option then look for heated car seats and heated blankets. These provide a great deal of comfort whilst keeping you warm and toasty. If budget is not an issue then buy the safest most robust heater you can afford.
Benefits of Portable Car Heaters
Visualize this…you’re in your car, it’s freezing cold and you can see your own breath. The windows are completely frozen and you can hardly feel your fingers. A portable car heater is such a practical thing to have handy for times like this. In a matter of minutes your windshield can be clear and the inside of your car is warm and toasty so you can go on your merry way.
If you live in a cold country or have particularly brutal winters that leave you shivering in your seat then you will be well aware of the benefits of a portable car heater. It’s just not comfortable spending time in a cold car and this is greatly exacerbated each and every time you step into your car during a particularly harsh winter. Why sit in the cold waiting for your engine to warm up when you can get your portable heater working – in many cases, almost instantly.
Keep Family Warm in Larger Vehicles
If you own a large car or an RV then you will probably already be aware that the heat from the front of the vehicle rarely reaches the back. Rather than have freezing passengers, shivering away on the back seats, crank up the heater and give your vehicle a blast of hot air to warm everyone up.
How to Maintain Your Car Heater
As you cannot rely solely on a portable car heater you will need to make sure that your internal car heater is in healthy conditions all year round. But how can you do this? Firstly, recognize that although it’s going to be winter soon, the health of your air conditioning system is a vital aspect of this. Believe it or not, during winter your air cooling system is working in overtime trying to defog and defrost your windows! Make sure that you test your defogger regularly to check for any issues. Perhaps it’s time to recharge the system or check for a leak in the hose? If you’re not comfortable doing this then of course you can seek professional help. As for checking your heating system, make sure you do this before the temperature really drops. Does everything seem to be running ok? Ask your mechanic to perform periodic radiator coolant flushes and refills and always make sure you check the quality and quantity of antifreeze in your vehicle.
To check your heating system you should turn on your heating system. Make sure you turn it onto the highest setting and then set the fan speed to high. Check all the settings: floor, dashboard, windscreen, etc If there isn’t enough heat being produced then there are likely problems. Low coolant levels could be an issue in this case. Make sure you top up your antifreeze levels but check thoroughly for internal leaks in the system, hose cracks, damaged water pipes, and leaks in the radiator cap.
On a more basic level, check for dust and blockages in the vents. Never underestimate how dirt can affect your vehicle’s functions!
Safety Tips When Using Portable Car Heaters
The safety precautions that you need to take when using a portable car heater isn’t dissimilar to those associated with a household portable heater; it’s mostly just common sense:
- Keep away from water – heaters + water = danger!
- Make sure you’re using the right type of heater for your vehicle
- Purchase a heater with a tip-over feature in case the heater falls for any reason
- Thermostat — make sure your heater has one!
- Plug heater into the correct power outlet
- Shut on/off when you’re not using it
- Regularly inspect the fuses/wires etc
How to Keep Yourself Warm In Your Car During Winter
There are many different ways that you can keep warm in your car during winter.
Why not try the following:
- Portable car heater – most sensible option!
- Electric blanket – instead of a portable heater, why not try a special heated blanket which has been designed for the car? Not only will you be warm but comfortable too.
- Heated car seat – perfect for winter mornings. Adjustable heated car seats will keep your body warm throughout your journey.
- Use hand warmers – you know that point when you enter your freezing car and you can’t feel your fingers? Well, portable hand warmers are absolutely perfect for getting feeling back in your hands.
- Park in garage – this way your vehicle is less likely to frost up.
- Cover your windshield – a good way to prevent your windshield from icing up.
- Drink coffee (or tea) – never underestimate the power of a warm beverage!
Best Portable Car Heater FAQ:
Not all. You will most definitely have to do your research before you choose which heater to buy. Make sure that the heater you purchase has a safety certificate and has been specifically designed for use in a vehicle. Check to see that it is compatible with your vehicle and also check to see if you can use them in moving vehicles. There are lots of heaters on the market and not all have been manufactured to the same standard unfortunately. Don’t risk your safety by opting for the cheapest you find. Look for reputable brands that will fit your vehicle’s spec.
Some do, some don’t. As we’ve mentioned before, not all portable car heaters are made the same. In fact, they differ quite greatly. Some portable car heaters are operated directly from the heater whereas others will benefit from a remote control.
Again, there is no one specific answer to this question. A good heater will warm up the car in a matter of minutes and some can even warm up in seconds but this depends on a number of different factors. The main factor is the power point. If the heater is being plugged into your car then it might need time to warm up.
