The Best Car and Truck Heaters | Buying Guide

When you need a little something extra in your car or truck during colder months, a portable vehicle heater might just be your answer! These small heaters can augment vehicle heating, spread heat in larger vehicles, and help get you to the ideal level of comfort on the road. They’re also great at defrosting windshields fast!

If you’re reading this, you’re probably curious about the best models out there, and you’re in luck! We’ve researched the top car and truck heating units on the market to bring you the best choices, so don’t get left in the cold.

Note that any products that plug directly into a lighter outlet just won’t pack enough punch to warm you up, so that’s why the products we recommend require light installation.

Ready to find the right model for you? Let’s take a look!

IXAER Car Heater

IXAER Car Heater

Coming in at 800 Watts, the IXAER Car Heater is essentially a ceramic space heater powered directly from your vehicle. Great for defrosting and defogging, this small but mighty heater is easy to install and is a highly versatile car or truck heating solution.

One of its main advantages is the near-instant heating that it provides. While you might have to wait a while for your vehicle’s primary heating to kick in, the IXAER Car Heater works right when the engine turns over. That means less time being uncomfortable in your rig.

Happybuy Diesel Parking Heater

Happybuy Diesel Parking Heater

For anyone with a larger vehicle they spend a lot of time in like an RV or camper van, we highly recommend looking into a parking heater to keep things warm and comfortable while the vehicle is off. Specifically, look for a model that has an external exhaust hose so you don’t have to worry about carbon monoxide poisoning.

If you sleep overnight in any vehicle during the winter, Happybuy’s Diesel Parking Heater might be just what you need. Installation is relatively straightforward for those who’ve done modifications to their vehicles already (and if not, you’ll find plenty of help on YouTube). While it does run on diesel, it also comes with a separate fuel container if your vehicle uses another kind of fuel.

This model blows some serious heat and lasts for a while and performs well at altitude.
