What to Look for When Choosing the Best Portable AC for Your Car 

When comparing different portable AC options, finding a unit that ticks all your boxes can sometimes be challenging. Consider what’s important to you and prioritize those to help guide your decision-making process. 

Below, we’ll cover a few factors you can look at when comparing portable air conditioners.

Cooling Power

How much cooling power does the unit offer? Comparing the BTUs of different units can help determine how much cooling power they have. The EcoFlow WAVE 2 offers 5100 BTUs of cooling power and 6100 BTUs of heating. 


Where do you plan on taking your portable air conditioner, and what do you plan to use It for? 

Besides using it in your car, do you also want to take it camping or have it cool down hot rooms in your home during the summer? 

If you’re looking to keep the unit in one place, installation versatility might not be a significant factor for you. But if you want to use your portable air conditioner for multiple purposes, convenient installation is essential to consider. 

Is the unit you’re considering able to set up in minutes? 

Is it easy to move between spaces and get it up and running again once you’ve transported it?

EcoFlow WAVE 2 ticks both boxes. 

Available Charging Methods

What charging methods will you have available when you use your air conditioner? 

While AC charging capabilities are great, will they be an option for you on the road? 

If DC car charging capabilities better meet your needs, ensure the portable air conditioner you’re considering provides it. 

If you’d also like to use a portable AC for camping, a unit that supports charging with portable solar panels might be more your speed. 

Ease of Installation

Installation can be frustrating, especially if you want to be able to use your portable air conditioner for multiple units by moving it from one space to another. If you don’t want to fuss with installation, opt for an AC that offers easy or no installation.

Noise Level

Do you plan on using your unit overnight or near other people who might be disturbed by its noise? 

Consider a unit with a Sleep Mode option that runs quietly. 

For example, the EcoFlow WAVE 2 can run as quietly as 44 dB in Sleep Mode.


Cost is always an essential factor to consider as well. Obviously, some portable AC units will come at a higher price than others. You need to balance what you’re looking to spend with the available features and quality that the device offers. 

Frequently Asked Questions

Can You Use a Portable Air Conditioner in a Car? 

Portable air conditioners are a great option to use in a car, RV, van, or truck to keep things comfortable when the temperatures begin to drop or climb. Make sure that any installation and charging is possible in your vehicle, or opt for a compact unit that doesn’t require installation. 

Can I Run a Portable AC Continuously in My Car? 

Whether or not you can run a portable AC in your vehicle continuously depends on several factors. The primary considerations are battery life (if any) and charging methods. Look for an AC unit with several charging options like DC and solar — so you have an off-grid option that won’t drain your car battery when you’re not moving.
