Best Portable Car Heater Buying Guide

Here are a few tips that will enable you to make the most of your purchase.

Type Of Heater

There are three common types of portable heater, electric, propane fuel heaters, and those that can be connected to your vehicle. Each has its advantages.

However, the ones that connect directly to your car are the most practical to use. Not only do they require a one time set up, but they are also better adapted to work in a vehicle.

Take, for example, a propane heater. In no time at all, it will use up all of the oxygen in your car. When this happens, you will be forced to wind down your windows, letting all the cold air in to start warming it up again.

While electric models are great, time is money. You have to park your vehicle, and wait, just to get your vehicle “charged up.”

Installation Location

Another important factor to familiarize yourself with is the location where your preferred unit is to be installed.

First, consider the dimensions and the suitability of your best portable car heater choice to fit in such space. Secondly, consider if you would like to drill holes in, for example, your car roof?

Bear this in mind, and you will be all smiles knowing that you made the best decision.

Output Ability

The output of any heater is measured in British Thermal Units (BTUs). While several units offer you a very large number, for example, 32,000 BTUs, that does not make it the best space heater.

For any vehicle size, 4,000 BTUs, on average, will do the trick. Buying a unit with much larger capacity, unless it can be set to 4,000 BTU’s, or unless you drive a luxury bus, for example, will have a negative toll on your vehicle battery.

Fog And Frost Defrost Options

If your preferred choice is a supplementary heater, then, you probably do not need to worry about this option. If, however, it is to be your primary heater, then you do need to bear this in mind.

A heater that is only designed to warm certain parts (e.g., your back, hips, and thighs) will not be able to get fog off your windscreen.


The truth is that portable car heaters are very inexpensive. However, after making a checklist of the features you prefer, you then need to compare the prices. But remember to look at product warranties.

If a product costs 25 USD more, for example, and offers you a far longer warranty, we suggest that it should be your preferred choice. Dealing with a manufacturer that backs his product with a good warranty is a great way to ensure you have a worry-free purchase.

So, What’s The Best Portable Car Heater?
