Zero Breeze Mark 2 Portable Air Conditioner: Is the Outdoor Air Conditioner Solar-Powered?

An RVer or an outdoor enthusiast might be excited about a portable air conditioner that runs on solar power. The Zero Breeze Mark 2 portable air conditioner can indeed be a perfect choice for them. Though not featuring a direct solar powering option, you can use the solar output to operate it someway.

Zero Breeze Mark 2 is basically a battery-powered portable AC unit. It can work up to three to five hours on its fully charged inbuilt battery pack, which has a 24V supply, however. There are different ways you can charge the battery from a solar output.

The Zero Breeze is a true air conditioner, not a cooler of any kind. It needs no water or ice to cool down a variety of outdoor space like RVs, campervans, trailers, boats, remote cabins, and more.

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 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.

Zero Breeze Vs CoolingStyle

CoolingStyle is a Hong Kong-based firm that offers one of the coolest portable air conditioners in challenge to Zero Breeze Mark 2. It is a 1700 BTU AC unit with a compact and handy profile of 8.5 x 10.6 x 15.7 inches.

Unveiled on Kickstarter back in 2019, it could attract 267 backers to collect as much as $100k and bring the project to life. It has three cooling levels and a 55 sq feet cooling capacity.

The 6.5KG device features other useful functions like dual USB ports for charging your phones and an LED light for regular lighting as well as emergency SOS signaling. It carries a price of $550 but is not available in the USA.

Zero Breeze Vs EvaPolar

EvaPolar is a leading maker of incredible portable air coolers, not air conditioners. It offers a range of cheaper and 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.

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

Final Thoughts

That has been our take on the Zero Breeze Mark 2 portable air conditioner.

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.
