Great in theory, but unfortunately it doesn’t really work like that.
Can a 12-volt
heater keep my car warm?
The amount of electrical power you would need to keep the interior of your car warm – or even just warmer – is so much that you would be continuously blowing fuses in the cigarette lighter’s circuitry, and possibly even damaging those circuits.
The good news is that there are still lots of ways 12-volt heaters can help. If we just shift our focus a little and think creatively, there are 12V heaters which can keep you toasty warm in cold weather, and even make winter driving safer!
What kind of 12-volt car
heater should I buy?
There are three basic categories we should consider:
- Hard Wired Heating – connects directly to your battery, but can really put out heat
- Personal Heating – that is, a 12-volt electric seat warmer or electric blanket
- Windshield Heating – doesn’t really keep you, or your car’s interior, warm, but may keep you alive
Hard wired heaters are much more difficult to install, requiring direct connection to your car’s electrical system and in-line fuses, as well as running copper piping and mounting the
But if you get one designed for a car, and have a professional install it properly, a hard-wired 12-volt car
Personal heaters are a great way to keep warmer when you’re driving, and without the hassle of difficult installation – or any installation at all, for that matter. They simply plug into the lighter socket and you’re good to go. They are also nice if the driver and passengers have different temperature preferences.
These would include seat warmers and electric blankets, both of which are amazingly effective direct heating products. Seat warmers are good for the driver and all the passengers (you need one seat-warmer for each person), while blankets are better for passengers – after all, you don’t want to get too comfortable and drift off to sleep when you’re driving.
Windshield heaters are small, low output devices that do little or nothing to warm the driver, passengers or cab of the car. What they do, though, and often quite well, is defrost the windshield and keep it clear in extreme situations – or at least one of them does…
If your car’s heating system is adequate but doesn’t always do the best job at defrosting the windows, the limited visibility can be dangerous, and a windshield

In our 2021 Buyer’s Guide to the best 12V heaters for your car, we will look at these basic categories, including one bonus category included because it is a really amazing product (and because I got quite hungry while writing this article):

What is the best 12-volt windshield
heater for cars in 2021?
We are going to start our 2021 buyer’s guide for cigarette lighter heaters with the most problematic type of
And why are they so problematic? Well, we have tried many different dashboard heaters and researched lots more, and there is only one possible conclusion: none of them is any good!
These apparently clever and often cool-looking gadgets promise to sit easily on your dashboard and keep your windshield frost-free, and maybe even heat up the car’s interior as well.
In truth, though, they do none of that. What they do is make pathetic little whirring noises, put out almost no heat, or even air, do absolutely nothing to clear the front window, in fact even reduce visibility by blocking your view and – to add injury to insult – often blow fuses in your car’s electrical system.
We had totally given up on the idea when we came across the nifty little Vosarea, which is not only the best car
Looking like an oddly misshapen hairdryer, the Vosarea 12 volt heater actually puts out some hot air, enough to help you warm up and defrost your front windshield. You can use it on your hands and feet, too, if they’re a little numb from long driving sessions.

The Comfier 12 volt seat warmer is safe, with a UL listed overheat thermostat and automatic shut-off, and it has a three stage shut-off timer as well. The control panel is easy to read and easy to use, and will not be too distracting – it is still recommended, though, that you do not adjust your Comfier seat
