Highlights of the Zero Breeze Mark 2 Portable Air Conditioner

When it comes to the highlights of the Zero Breeze Mark 2, creating a long list isn’t hard.

Camping trips are perhaps the most ideal time to use the portable air conditioner. That’s because it’s so versatile. Whether you’re a tent or an RV camper, you’ll be pleased to know that it excels in either situation.

More specifically, it can save you money if you’re an RV camper as well. Don’t worry about running the vehicle’s AC or purchasing a window unit. You can simply keep the Mark 2 nearby and have it running for you. Not only will this save you money from purchasing a window unit for your RV, but you’ll also save the life on your vehicle’s battery by not always having it running.

Other less obvious uses include using the Mark 2 while in cabins, while fishing, or even in a small room. If you’re thinking “How in the heck could you use it while fishing?” You’d be surprised.

Many fishermen, such as catfishermen, will hunker down in one spot for an evening or even an entire night. Commonly, these fishermen will use open-ended tents or weather-protection pods to guard themselves against the elements while they’re out.

While these units are great for protection against the window, rain, and other debris, they aren’t going to make your stay any cooler. Some of the best fishing occurs both in the night and day, both of which are susceptible to grueling heat depending on where you’re located. Take the discomfort out of your favorite activity by running a Zero Breeze Mark 2.

Why suffer any downsides when enjoying your passion? Take it away with this portable air conditioner. You’ll also find that the Zero Breeze Mark 2 is incredibly portable. And, not just a “fake” portable air conditioner like so many other brands specialize in. If you do a simple Google search, you’ll find tons of air conditioners that are labeled as portable. However, they’ll weigh up to, if not in excess, of 50 pounds.

That’s not portable. That’s an air conditioner with a carrying handle attached. The Zero Breeze Mark 2 weighs a little bit more than 15 pounds, making it a truly portable air conditioner. You can bring it with you wherever you go.

Are you taking a hike a couple of miles out before setting up? Carrying this with you won’t be difficult.

Other highlights of the Zero Breeze Mark 2 include:

  • Able to cool the area within 10 minutes of operation
  • The battery will last up to five hours and is easily rechargeable
  • Able to drop the temperature around it down to a chilly 30 degrees for maximum comfort
  • Able to be charged conventionally or through your car or solar power
  • The air conditioner and battery can be combined into a single unit, making it that much easier to take with you wherever you go
  • Is roughly have the size of other traditional portable air conditioners

Specs Behind the Zero Breeze Mark 2

Specs Behind the Zero Breeze Mark 2This section is dedicated to the nitty-gritty information that we all value so much. Keep reading to find out how this information translates to you.

Here are the specifications behind the Zero Breeze Mark 2:

  • Four working modes, including Cool, Fan, Sleep and Super Cold
  • Four speed levels to adjust to whatever conditions you’re in
  • Rated at 52dB(A) for sound
  • 650W cooling capacity
  • 24V DC Rated Voltage
  • The cooling rated input is 240W
  • Unit is 20” L x 10” W x 11” H
  • 5 pounds in weight
  • IPX4 moisture protection
  • Dual house vent hose exhaust configuration

So, what do all of these technical specs mean to you? Here’s the breakdown.

The four working modes are essentially the functions of the Mark 2. You can have it set to a light cooling mode, as a generic fan, or as a super cold fan. Of course, a sleep mode is also functional.

This means you can adjust the unit to work in whatever scenario you’re in. If you simply want a light fan, you got it. Is it 100 degrees outside and you’re wanting to get nice and icy before bed? Throw it on super cold. The versatility with the Mark 2 goes a long way.

Four levels of wind speed mean that you can adjust the AC’s fan speed at four different levels. Again, this is a large factor in why the Mark 2 is such a versatile portable AC unit.

The 52dB sound level means you can expect the Mark 2 to work relatively quietly. Keeping the tent cool is great, but it’s not worth a loss of sleep if you’re kept up by constant humming and drumming. The Mark 2 will comfortably cool your area as you drift into slumber.

In terms of size, the Mark 2 is ergonomically designed to fit in most spaces. Whether you want it in a tent, pod, RV, car, or anywhere else, chances are that you’ll be able to fit it into most spaces.

Of course, weight is a large reason why this unit is so portable as well. 16.5 pounds is incredibly lightweight when it comes to air conditioning units. Most other standard window units will weigh upwards of 30 pounds if not more than 50. Why spend money on something that you can’t move yet produces the same effect as the Mark 2?

On the downside, the Mark2 does take quite a bit of power to charge and the battery doesn’t last exceptionally long. This isn’t so much of an issue if you’re near a power supply, but it’ll likely need to be conserved if you’re venturing out into the wilderness.


  • Extremely lightweight, making it a truly portable air conditioner
  • IPX4 moisture protection means you won’t have to worry about light rain or moisture developing onto it overnight
  • Four working modes to tackle whatever situation you find yourself in

  • Relatively quiet for the amount of cooling it generates
  • Able to cool its entire area within 10 minutes
  • Able to drop the surrounding temperature to 30 degrees, making it ideal for those who love to get snug
  • The ergonomic design will allow you to fit this AC into the most convenient spaces


  • The battery only lasts for five hours when not plugged into a power outlet
  • Requires quite a bit of power to fully charge efficiently

Here is a list of items you can expect to arrive when you purchase the Zero Breeze Mark 2:

  • The air conditioning unit
  • A 24v output 240W power adapter
  • An 80cm drainage pipe
  • An 80 cm front air outlet duct

The Difference Between the Zero Breeze Mark 2 and Mark 1

The Difference Between the Zero Breeze Mark 2 and Mark 1If you’re an owner of the Zero Breeze Mark 1 or believe that the Mark 1 may be a better purchase in terms of cost-effectiveness, you may be on the fence about purchasing the Mark 2. Don’t be. The Mark 2 is better in every way when compared to the Mark 1.

The biggest difference between the two is the cooling BTU associated with each unit. The Mark 1 is rated at 1,100 BTU/hour while the Mark 2 is rated at 2,300 BTU/hour. Yes, this does mean that Mark 2 requires more energy output to achieve its function.

However, you’ll reap plenty of rewards. Not only will the Mark 2 cool the area around it to a much lower temperature, but it’s also much more efficient. The Mark 1 takes between 30 minutes to an hour to achieve the correct temperature. You can expect the Mark 2 to do the same thing but in only 10 minutes.

The area that each cover is also significantly different. Ideally, you can use the Mark 1 in a two-person tent. With the Mark 2, you can cover a three or even four-man tent quite comfortably. This range also extends outside of tents. Cars, small rooms, weather-protection pods, and even a cabin’s sleeping quarters can all easily be cooled with the Mark 2. You won’t get the same level of cooling with the Mark 1.

On the downside, the Mark 2 does weigh a few pounds more than the Mark 1. However, this is only a few pounds difference and won’t impact the portability of the Mark 2 at all. The Mark 1 also comes with a 3W Bluetooth speaker for your enjoyment. The Mark 2 doesn’t come with any speaker. But, we’re talking AC units here, not speakers.

Overall, the Mark 2 outshines the Mark 1 in almost every category that matters when it comes to quality air conditioning units. The Mark 1 had a great run, but the new, true champion has arrived.

Where Can I Use My Zero Breeze Mark 2?

Where Can I Use My Zero Breeze Mark 2Ideally, the Zero Breeze Mark 2 will be used in a tent while camping. However, it’s great for so much more than that. Here are some ideas of where you can get a lot of good use out of a Mark 2.

  • Using the Zero Breeze Mark 2 in a Trailer

Everyone loves camping. But, some love camping while still keeping the amenities and comforts of modern-day life. And, there’s nothing wrong with that.

Instead of purchasing a clunky, heavy window unit for your RV or trailer, consider purchasing the Zero Breeze Mark 2. Because of its strength and ability to cool an area quickly, it’s a great air conditioner for your trailer or vehicle.

Don’t spend all the time, effort, and money on a low-grade window unit. The Mark 2 gets the job done more effectively and while still being portable and usable outside of your trailer.

  • Using the Zero Breeze Mark 2 in a Pod

Weather-protection pods and makeshift shelters are a popular option for those who love spending time in the wilderness. They protect you from the elements while still being able to enjoy the backcountry joys you know and love.

But, even the best pods and shelters won’t protect you from the grueling heat that may occur in the Summer. Use the Zero Breeze Mark 2 to fight off unbearable temperatures even when you’re out in the middle of nowhere.

  • Using the Zero Breeze Mark 2 in Your Room

Buying a portable air conditioning unit for your room may seem a bit silly. Why spend the extra money on a portable unit if you’re just going to have it in your room all day every day? The answer is you shouldn’t.

However, if you’re someone who can make frequent use of Zero Breeze Mark 2 AND need an AC unit for your room, this is going to be your best bet.

It gets the job done both inside and outside, saving you money in the long run by making it possible to get the best of both worlds in one purchase.


At the end of the day, the Zero Breeze Mark 2 is the only portable air conditioning unit you’re going to want to have by your side in the outdoors. Between its versatility and portability, it’ll be the highlight of every camping trip or outdoor adventure you find yourself on.
