Best Portable Air Conditioners for RVs: ZeroBreeze Vs EcoFlow Wave Vs IcyBreeze Vs Evapolar

A camper or an outdoor enthusiast might be fancying a full-fledged and real outdoor air conditioner that runs on portable power. The Zero Breeze Mark 2 portable air conditioner has been a fine choice for a long time. EcoFlow Wave is a rather new model with a much better cooling option.

The Zero Breeze doesn’t have an option to run directly from a solar array, but you can operate it from a solar-based power station. Meanwhile, the Wave has a built-in solar charging option, which you can use to charge its optional add-on battery at a rate of up to 200 watts.

Until the release of Wave, there have not been many competitors to Zero Breeze as a true portable air conditioner. Besides these two, we only have some brands like IcyBreeze and EvaPolar with some water-based cooling solutions that also work on batteries.

Update 1: As a piece of happy news for those who are looking for a Zero Breeze competitor, EcoFlow, the leading vendor of portable solar power stations, has announced a new product.

Called EcoFlow Wave, it is a 4000BTU air conditioner with the EcoFlow battery tech in the DNA. It is expected to have an official release in the second week of May 2022.

Update 2: EcoFlow Wave comes with an add-on battery of 1008Wh capacity, which can power the device for up to eight hours, which includes around three hours of cooling time and five hours in fan mode. You can also run it on EcoFlow’s Delta Max and Delta Pro with a DC cable for more cooling time.

That is, you don’t need to buy it with the add-on battery if you are already an owner of Max or Pro.

Update 3: EcoFlow Wave pricing details are announced. The Wave alone has got an MSRP of $1499, and it comes at $2299 with the add-on battery. But both the Wave and bundles have got limited quantities of Super Early Bird, Early Bird, and Pre-Order units for early comers at a discount of up to 40%. Thus, Wave has a price of $899 and Wave with the add-on battery comes at $1399 for the 100 units each.

Zero Breeze Mark 2 is basically a battery-based portable AC unit. It can work up to three to five hours on its fully charged inbuilt battery pack, which offers a 24V supply.

As a true AC, the Zero Breeze needs no water or ice to cool down the outdoor spaces like RVs, campervans, trailers, boats, remote cabins, and more. Meanwhile, both Evapolar and IcyBreeze work with cold water.

Zero Breeze Vs IcyBreeze Vs Evapolar Portable Air Conditioners

If you are looking at buying a portable cooling system, these three brands are the much reliable options.

Zero Breeze offers you a real portable air conditioner, while the other two brands have got water-based air coolers.

EvaPolar is the cheapest brand for you to get a portable air cooler. It has got its product line with a price of around $100, whereas IcyBreeze has its more powerful air coolers with a price of around $300.

For a Zero Breeze, you need to spend around $2000, by the way.

Anyway, let us have a look at all the products in detail in our take on the Zero Breeze Vs IcyBreeze Vs Evapolar Portable Air Conditioners below.

Zero Breeze Mark 2 Portable Air Conditioner

Zero Breeze is an amazing technology innovator that is known for its engineering in slimming down high-power appliances to small, compact, and portable solutions.

Mark 2, as its name implies, is the second-gen of its much-frenzied portable air conditioner for camping and RVs.

Specs-wise, it is a 240W low-power air conditioner. It runs on a regular AC wall outlet with the included adapter or the built-in 24V 35Ah/840Wh lithium-ion polymer battery pack.

Of course, with a Zero Breeze, you no longer need to keep your gas generator running to cool down your outdoor living spaces. By the way, the brand has its solar generator, ElecHive 2200 with a dedicated 180W outlet for Mark 2.

Anyway, with 1/5 of the power of a regular air conditioner, you can run a compact and handy AC in your outdoor spaces like a campervan, RV, tent, boat, houseboat, and more.

It can produce a decent cooling of 2300 BTU. Thanks to its powerful compressor, it is enough to reduce the outlet air temperature by 20°F/11°C in below ten minutes.

Zero Breeze Mark 2 History

Zero Breeze had its birth back in 2016. The first-gen Mark 1 outdoor AC unit attracted millions of people across the world as it was launched on Kickstarter. It could collect $574k from nearly 1200 backers to become the world’s first portable air conditioner.

Mark 1 was actually a portable AC with a combination of a night light, a Bluetooth speaker, and a phone charging station. It could cool a space of 50 sq ft down to 44 ℉ in a few minutes.

The team Zero Breeze upgraded its portable AC to Mark 2 in 2019.

Obviously, the new model received a lot of new features to come out to be a better and more reliable battery-powered air conditioner.

Launched on Indiegogo, it could gather nearly 1M USD from over 1000 backers. Currently, we have Zero Breeze Mark 2 available at a price of around $1400.

How Solar Power Runs Zero Breeze Mark 2

There is no way you can recharge Mark 2 with a solar panel directly. However, you can charge its battery pack from a solar output in two methods.

The first is to use the optionally available DIY cable that comes up with a GX16-4 connector. This can help you easily transfer power from a 20V-36V solar output to the dedicated Mark 2 battery. The cable costs you $20.

The second option is to use a solar chargeable battery to back up Mark 2’s battery pack. In this case, you need to use the recommended cables and connectors as per the output and voltage of the secondary battery you want to connect.

If you have got a 24V battery, the same cable with the GX16-4 connector is fine. If the battery is a 110/220V unit, you will require Mark 2’s own AC/DC adapter to establish the connection.

For another voltage, the brand offers an exclusive transformer to make sure the Mark 2 battery gets 24V. We have all the required accessories and their specs in the table below.

Zero Breeze Mark 2 and ElecHive 2200

ElecHive 2200 is Zero Breeze’s entry into the portable solar market. This is a midrange 2400Wh solar-based power station for all your off-grid and emergency power needs.

It comes with an industry-leading 2200W inverter and a variety of charging outlets, including four AC sockets and multiple DC and USB outlets.

The notable thing with ElecHive in connection with Mark 2, as said above, is its integration of a dedicated 24V connector to run the air conditioner off the grid.

That means you get yet another way to recharge the portable AC from a solar source.



ElecHive 2200 comes with a 12-30V, Max 240V MPPT Anderson input to let you charge it from a solar panel. The brand also offers a four-fold solar charger with higher conversion.

With the maximum solar output, you can charge ElecHive 2200 fully in four hours and utilize the backup to run your Mark 2 in the wild.

How Cold Does It Get?

Zero Breeze Mark 2 portable air conditioner is not meant to cool a full room like regular ACs.

It can ideally cool the areas in front of its fan to realize a personal comfort zone for one or two to sleep or escape from simmering summertime heat. The air in front of Mark 2 will be having a 10F lower temperature than the ambient climate.

Price and Availability

Zero Breeze Mark 2 has a base price of about $950, as of writing this. With a unit of the battery, it costs $1400. You get the product in multiple bundles with and without batteries.

A two-battery bundle is available at $1800. Getting it with two battery packs is a cool idea for outdoor use. When you use one battery, you can keep the other one in charge.

Zero Breeze Competitors

There are actually not many competitive models to Zero Breeze Mark 2. Though a handful of innovators introduced some models, the challenges in portable air conditioning seem to have eventually set back their efforts.

Anyway, we would like to have a go-through of some of the models that could challenge Zero Breeze Mark 2 in the portable air condition market.

IcyBreeze Portable Air Conditioner

IcyBreeze is an innovator of portable air conditioners and coolers. Apart from multiple variants of its water-based evaporative air conditioners, IcyBreeze offers a Golf Cart Cooler Rack and a handful of other products for RVers, campers, and other outdoor enthusiasts.

The brand offers its portable air conditioner in two variants; IcyBreeze V2 Pro and IcyBreeze Platinum.

Both variants are not ideal replacements to the traditional air conditioners, and also not to the Zero Breeze Mark 2 air conditioner. They are actually water coolers that are capable of cooling down smaller spaces like RVs, camping tents, and more with the consumption of less power.

The IcyBreeze is also a cooler with a generous room of 38 quarts. You can use the space to store your food and beverage items fresh.

When it comes to the air conditioner, the machine features a three-speed, high-performing fan to quickly cool down your outdoor spaces. The built-in 12V battery gives it a life of up to 6 hours on the lowest fan speed.

To add to its portability, the air cooler features large wheels, ergonomic handles, and more. The outer shell of the machine is made of durable and solid plastic for longer life.

Zero Breeze Vs EvaPolar

Next, we have EvaPolar.

EvaPolar is a leading maker of incredible portable air coolers, not air conditioners. It offers a range of cheaper and more reliable evaporative coolers for outdoor use. Most often, Zero Breeze is compared to EvaPolar’s coolers.

As you see, a cooler is indeed a totally different product. It works by using water or ice to cool down the air just in front of its outlets. EvaPolar has got multiple variants of its much-touted air coolers for outdoor life, RVs, campervans, small cabins, and more.


Links To Buy: EvaChillEvaLight PlusEvaSmart

EvaCHILL is one of its best-sellers and is the base variant of its series. It is an ultra-portable air cooler that you can easily take anywhere by holding on to its handle. A removable water tank lets you ensure cooling for up to nine hours on a single refill.

As a 7.5W machine, you can charge it from a power bank, a power socket, or even from a laptop USB port. It has a limited cooling capacity of 340 to 1190 BTU per hour in a coverage area of up to 2 to 2.5m² just ahead of its fan.

EvaPolar EvaChill features a size of 6.69 x 6.69 x 6.77 inches and it weighs just below one kg.

EvaPolar also offers two top variants to the model. EvaLight and EvaSmart are the models with 10W and 12.5W capacities. They can respectively cover an idea of 2 to 5 m² and 2.5 to 3.5m² with the BTUs of 340 to 1190 and 340 to 1360 per hour.

What to Buy?

In the comparisons, Mark 2 is surely the best pick for someone who is looking to buy a portable AC. Though a bit pricy, Mark 2 is worth trying. Listening to all former complaints, the company has engineered the new Mark 2 with the latest technologies and better cooling.

By the way, EvaPolars and IcyBreeze, as you see, are not true air conditioners, but air coolers. If you want an air conditioner, Zero Breeze is your choice. To run a cooler, you need to refill the water in it in a while. Plus, as you see in the specs, EvaPolar coolers offer far lesser BTUs compared to Mark 2.

EcoFlow Wave Air Conditioner

EcoFlow Wave is a 4000 BTU portable air conditioner with an add-on battery of 1008Wh capacity. You have it with a built-in solar charging option apart from the other typical charging options such as a wall socket, carport, and more. But with a solar panel of 200W, you can charge its add-on battery directly.

Moreover, EcoFlow also avails Wave without the add-on battery. In that case, you can run it on the brand’s Delta Pro or Delta Max via XT150 cable.

You can also run it from any other power station, including the other EcoFlow models via their AC sockets, but running it with Delta Pro and Max via XT150 cable makes it 28% more efficient.

EcoFlow Wave Air Conditioner Review


You don’ need to worry about the condensation water from Wave.

The brand has designed an evaporative system to drain the water from condensation with the heat from the compressor in places with humidity above 70%. That means, it will leave no water behind and it doesn’t also store water in a tank requiring you to empty often.

The portable air conditioner is indeed a super cool product with its tiny size, portable design, and easy-to-use profile. You can carry it in your RV and trailer and keep it cool throughout the night.

With the included add-on battery, Wave can run up to eight hours and you can achieve more runtime using either Delta Pro or Delta Max. The brand has it on sale individually with and without the battery, and in bundles with the EcoFlow’s flagship power stations.

Final Thoughts

That has been our take on the Zero Breeze Vs IcyBreeze Vs Evapolar Portable Air Cooling Solutions.

We have covered all the aspects of the device and compared it against its top competitors. It is not much practical to run an air conditioner directly on solar power as it requires more power. It is where Mark 2 is a fine choice you can charge from a solar source though in an indirect way. Share your thoughts in the comments below.
