Does the Zero Breeze Battery Powered Portable Air Conditioner Really Work?

Does the Zero Breeze Battery Powered Portable Air Conditioner Work?Camping is really supposed to be all about enjoying nature and roughing it. However, there are some of us that just cannot resist the comforts of home. Now more than ever there are some great opportunities to take some of these along with you for your comfort. Can you believe that air conditioning may be one of them?

There is a certain segment of the population that just cannot wait for camping season to begin. For many, the chance to get away from it all for a few days or weeks means having to wait until winter has finished and the dog days of summer begin again. When those hot humid days start coming we cannot wait until we can unpack the tent and get at it! One of the parts of tent camping that sucks is the very hot mornings when the sun starts to beat down on your tent and you are forced to get up early no matter what. Well, those days are officially over! The all new Zero Breeze Battery Powered Portable Air Conditioner has just changed the face of camping forever!

The Claim
The claim is that by using the Zero Breeze Battery Powered Portable Air Conditioner you can have the luxury of A/C no matter where you are or where you are going. The totally portable unit can deliver enough A/C power to chill out a 50 sq ft. room or tent or even camper van or some other type of vehicle that may not have a/c or may require the vehicle to be running when the a/c is in use and you don’t want that.

The Hype
The majority of the hype that the Zero Breeze Battery Powered Portable Air Conditioner has generated stems from the Kick starter Campaign that they successfully started in order to raise money to get the project green lit. The initial campaign was set up to generate $100,000 but to date they have raised almost a ½ Million. Not too shabby indeed!

The Cost
The cost of a Zero Breeze Battery Powered Portable Air Conditioner is a very reasonable $399.00. When you look at the price of regular a/c units or even the portable ones that you can take from room to room the price for the Zero Breeze is right there with them. No it will not cool an area quite as large of some of those but it does offer you options that the larger electrical powered units cannot fulfill and that is the portability.

The Commitment
Other than making sure that the batteries are fully charged with power there is very little in the way of commitment necessary for the Zero Breeze Battery Powered Portable Air Conditioner. It is small enough to store in a trunk or a small shelf in the garage when not in use.

As someone who absolutely loves to camp but absolutely hates the mornings in a tent when the sun starts to beat down on the vinyl and you feel like you are in a sweatshop in a third world country or in a broiler getting cooked like a chicken this product is truly a godsend. That fact that you can take this with you whenever you are going out into a really heated area or suffering from the extreme heat we have seen around the world in the past few years is truly revolutionary in nature. The Zero Breeze Battery Powered Portable Air Conditioner will not just keep you cool when you need it most but the built in USB Charger will also let you make sure that your cell phone remains charged when you are out in the woods camping or spending a day on the water boating or wherever your adventures take you. The unit also has a built in Bluetooth Speaker so you can crank the tunes while getting cool and if the sun happens to go down while you are partying, no worries because the unit also has a built in LED light as well.

Final Zero Breeze Battery Powered Portable Air Conditioner Review

In addition to the excellent features listed above the Zero Breeze Battery Powered Portable Air Conditioner also has 3 separate settings for the level of coolness and the fan output as well so there will be comfort for every conceivable situation you may find yourself in when out of doors. Simply put, the designers have really thought outside of the box and come up with a truly great and innovative product.

Our Recommendation
For anyone who loves being outdoors but is susceptible to the at times over powering heat this Zero Breeze Battery Powered Portable Air Conditioner is for you. Small children and babies are much more likely to succumb to the heat and having one these can make the difference between enjoying the time outdoors of having to pack it in and head into cooler climes. Buying a Zero Breeze will not only make you cooler, it will make you so much “cooler” than the other guy. For some other great camping ideas check out this camping cookware.

is there any reason this could not be used indoors?


E K March 13, 2017 at 12:46 pm

It can’t possibly work indoors. Air conditioners transfer heat from indoor air to a fluid and then exhaust it to the outdoors. If it is exhausting back into the same room, that room will not cool down. It’s daft.


Ahmed April 7, 2017 at 2:30 pm

Well they claim to vent the air out using a clip-on pipe, which seems consistent enough


Ed October 24, 2017 at 11:35 pm

Not to be picky and I’m not yet familiar with this device, but I have to note that they did show a coiled ducting for inside use, if you had watched closely.


KL May 5, 2018 at 4:27 am

Could also be using thermo-electric cooling like peltier devices on CPUs in computers They still need to be vented BUT no compressor or refrigerants at all. 100% solid state.


david June 8, 2018 at 5:47 pm

KL, not true. Even their spec page claims rotary compressor and Dupont R134a refrigerant.


runaway June 23, 2017 at 6:03 pm

How long does the charge last?


Alberto Knox April 27, 2018 at 5:23 pm

If you duct the hot condenser air outside it would work … kinda. It claims a power of only 1100BTU. That is very little air conditioning, and it’s not cheap. For about 1/4 the price you can get a small window air conditioner with 4-5 times the cooling power that plugs into a wall socket. Even that is a small air conditioner though.

Be aware the $399 price does not include the battery, which costs more than the air conditioner.


Geraldine Lippincott July 30, 2018 at 10:14 pm

Sure, if you don’t mind a pool of water on the floor.


david October 20, 2018 at 1:40 pm

The air conditioner does not work at all. Mine arrived after a 18 month wait and did not cool down anything. It did not work. I have been in constant contact with their customer service department and although they say they will replace it it has been a year and no new unit or refund. Do Not Purchase, unless you like throwing your money away


DC April 24, 2017 at 3:47 am

I’ll bet it is just a portable swamp cooler, consider how little power it uses. Works OK in the desert, but not effective in high humidity environments. It is way overprice for a simple small swamp cooler.


Nerg Norfle May 21, 2017 at 7:30 am

Nope. Guess again. It’s based on a rotary compressor.


Geraldine Lippincott July 30, 2018 at 10:16 pm

But what they don’t tell you is their manufacturing is shoddy. My unit does not drain through the drain tube.Water pools on the underside of the unit, and support seems to be non-existent.


Juan C Gonzalez February 6, 2019 at 4:45 am

hi I used silicone sealer all the way around the water outlet tip. That was the end of my water under the machine! Created a perfect seal.


Rob May 19, 2017 at 6:16 pm

Can we buy it yet or not?


Jessica May 21, 2017 at 4:54 pm

We have been waiting on ours to arrive since March and still have not gotten them. We ordered two but are starting to regret it.


Where did you buy July 13, 2017 at 5:43 pm

Please let me know where you buy this. I want one for my dogs when we go places they can be cool


Jonny August 17, 2017 at 3:25 pm

HI Praxis, looking to buy one, I will pay you 100 bucks more than you paid, Thanks, see email


Roger June 1, 2018 at 2:04 pm

Got my Zero Breeze last August.
Short story…It does work… However I had hoped to use it to cool my VW Van while driving, it just doesn’t put out enough. So really doesn’t work for me.

Would be willing to sell.



Neil June 3, 2018 at 5:53 am

Hey Roger, do you think it puts out enough to cool at night? I’m planning to use in an suv

Keri Anthony July 2, 2018 at 2:02 pm

Man, Im so glad I read your review, I have a 1970 VW bus I was going to get this for, wont do it now, Thanks

Chris July 7, 2018 at 6:19 pm

Hey Roger I am in Columbus I am interested to buy your zero breeze

Ryan July 23, 2018 at 2:30 pm

Hi Roger,
can you sell your Zero Breeze unit to me?
I am in China. It will be highly appreciated if I can have your positive reply.
Send email to me.

best regards!

James t grosslight March 5, 2019 at 5:00 pm

Looking to buy a zero breeze

Vu Au April 25, 2019 at 3:34 am

Roger,you still have your unit? I’m interesting in buying it from you. 601-259-9922 thank

Vu au April 25, 2019 at 3:30 am

Will buy one from you Jessica.


adsr May 31, 2017 at 4:04 pm

So this “review” is basically retyping the feature list from the campaign without having any contact with an actual specimen? I guess so, there’s no word on the actual performance plus they aren’t sending them yet I think.


Jim May 31, 2017 at 6:10 pm

Jessica, has the company contacted you with an update on your order? Someone needs to ask the simple question? does it cool or not? A simple bench test would be nice. Set the unit in real conditions say around 90F and check the temp with an Infrared Thermometer……Now thats the question, what the temp on the cool side outlet….Hey if it works im in…….. I did see one video where the temp was checked with an infrared thermometer at 85F and the cool side outlet was 47…..Thats awesome if true…Im surprised that the company hasnt hit on this point yet…its an AC unit forget about the other stuff for now……


Christopher Rinebold November 30, 2017 at 9:29 pm

Commenting as an experienced HVAC-R engineer for the past 30+ years. The unit is designed to cool 50 square feet. That’s just under 2 cubic yards. Or 5’x5’x2’. Humm, says nothing about insulation or outside temperature. I’m sure it will help. Would have liked to see a demo on how low the temperature gets in a tent when it’s 90 outside after factoring the oven effect of the tent. Good for thought, you can make ice in a freezer when it’s sealed close. High insulation value and air tight.That’s colder then this unit gets. But leave the door open on a freezer and it will never get cold enough to freeze. I really need to see the comments from customers after they ship these out. Until then i think there are too many variables against customers being satisfied.


Bill Smith December 23, 2017 at 9:59 pm

Christopher, you are wrong. The article says (as you indicated) “50 square feet”, not 50 cubic feet. You indicated in your comment that 50 square feet is “just under 2 cubic yards”. That doesn’t make sense. Actually, 50 cubic feet is just under 2 cubic yards.


Jim Braun July 3, 2018 at 11:19 pm

The Temperature difference across the evaporator coil is not enough to determine capacity, you must also be given the quantity of air flowing in CFM (cubic feet per minute). A freezer can develop temperature differences of 70 degrees (from 90 to 15) but would make no noticeable difference in the room if the door were left open. Also I doubt that the 1,100 BTU/hr rating is accurate – AC manufactures use weighted ratings meaning the 1,100 BTU value is the effective cooling power over a 24 hour period if the AC unit were left on for the entire 24 hours with the normal heat load being very low most of the day (morning & night). Fact is Roger’s reply about this device not cooling a VW bus says volumes about the actual capacity. A VW bus has only about 200 cubic feet of space which is a tiny volume. A 15 x 15 std. room has 1,800 cubic feet and requires about a 12,000 BTU (weighted) unit for cooling on a 90 degree day. The device is nothing more than a personal fan – one person can expect to be cooled if it is pointed directly on him or her. Thanks Roger! Like Keri I was thinking about the Zero Breeze for an old SUV also


Pete June 3, 2017 at 8:25 pm

Love to buy one for the sailboat but waiting for some customers reviews.


Adam June 4, 2017 at 2:37 pm

Have you used the product ? Judging by the article ( press release ) you haven’t and this shouldn’t say review. Useless website


Craig Ruth June 19, 2017 at 5:39 am
Craig Ruth June 19, 2017 at 5:15 am

Love to give feedback but at this point it seems to be vaporware.Live and learn.


Lucy grafton June 26, 2017 at 2:13 pm

We bought a zero breeze and would like to know when it will be here. June 29 2017


Richard Chase July 13, 2017 at 1:51 am

I ordered one on Kickstarter. My backer number is under 200. It appears only 10 or so units have been delivered thus far. A second larger batch has been promised but no one has one yet. Reviews on the Kickstarter comments section from those that have received one claim some level of cooling; ranging from a 12 degree temperature drop (input temp to output temp) to a 30 degree drop. The variance seems to be from the fact the first batch had some admitted quality control issues. Additionally no one has received a battery yet. They claim that’s because they are 500Wh lithium ion batteries that they needed to ship my sea instead of by air and that they should be arriving soon. We’ll see. I’ll post an update here if/when mine arrives and how it works.


Richard Chase August 4, 2017 at 10:06 pm

Mine arrived today. It’s part of a second batch of 150 units. There is another shipment of 600 that is supposed to ship sometime this month (August)

The unit is a little louder than expected but It seems to work pretty well. I measured the input and output air temps. After running for 15 minutes it cooled input air at 82 to an output temp of 56. The exhaust air was over 100. The power draw when running was 156 watts when running on AC power. The battery did not ship with the unit and is supposed to arrive in the next month or so.

The airflow is about the same a car air vent (one vent) running on high.

I do not think this could substantially cool a hot car, but I do think it could make a difference in a tent in the evening when camping.


Jerry August 6, 2017 at 2:44 pm

Thanks for Richard sharing. May I know is that can powered by 12v battery like car battery ?


billy sharpstick August 7, 2017 at 2:55 pm

Mine was delivered today(8/7/2017). I measured 76F in, 64F out and 110F exhaust. Twelve degrees differential is considered acceptable minimum for AC units.
This is similar technology to portable AC units, but smaller. Bear in mind that two duct portables are better than one duct. Two duct units pull in outside air to cool the unit and exhaust back out(typically through a window). Single duct units exhaust the air out the window, but require ventilation so outside (hotter) air can be drawn in to replace that air.
I might try to build a curtain/tent around the bed with just the cool air duct blowing into it, and the intake vents outside in the main tent or camper area. That still requires some ventilation for air exchange, but might concentrate the cool air by the bed.
At any rate, 1100 btus are not adequate to completely cool off a cabin tent size space in hot weather.


Jonny August 17, 2017 at 3:21 pm

Hi Billy,
Let me know if you would like to sell your unit. I will give you a hundred dollars more than you paid. email me would be great if you catch this post. Thanks


Praxis August 10, 2017 at 8:37 am

Mine has come in, and it works like a smaller than usual window air conditioner unit. When running off of 12 volts, got a battery array already setup, it uses very little power. The unit does put out heat in large amounts so remember to vent that heat elsewhere or to put it to use. The air it shoots out the vent does a very good job on cooling yourself off. Doesn’t really do much to lower the ambient temperature, but it does keep it from elevating. So if you have the battery power for it, you can run it at night to pre-cool your camper or tent or even your room and then when the sun is up, KEEP your tent/room cool. Just remember to keep it level or it’ll make ALOT of noise. Definitely for someone needing a better option for their camper who doesn’t want to spend hundreds on petrol/propane gas. Not so much for a large apartment, maybe a small tiny new york hideaway hole type.


Deb August 13, 2017 at 7:55 pm

Don’t buy this if you want it for a vehicle. It’s a huge disappointment and they didn’t send a car adapter as promised when we first donated.
It’s just a flat out lie!
I’ll never back a Kickstarter again. Twice we’ve been burned.


Jonny August 17, 2017 at 3:22 pm

Hi Deb, let me know if you would like to sell your unit. I will pay you a hundred dollars more than you paid. Thanks, see email


Patrick Boyd December 5, 2017 at 7:35 pm

I paid 600 plus dollors for this system and still dont have one Why


ROBERT January 28, 2018 at 3:08 am

This unit could be perfect for my teardrop camper looking forward to availability.


Jesse Turnipseed February 15, 2018 at 3:18 am

Bill 50 square feet is a measurement of two-dimensional area. There isn’t any height in sq ft only length and width. So it would be logical to assume that 50 cubic feet are the measurement of area needed to calculate since no three-dimensional object can occupy a two-dimensional space. And Bill don’t be a dick


Em Turner February 20, 2018 at 3:54 pm

Mine arrived 18 months after ordering, and thankfully just before Hurricane Irma hit us here in Florida. For the five days we were without power after the storm passed, we used a combination of electric fans powered by our gas generator and the Zero Breeze to keep our family room as cool as possible.

We vented the exhaust with a homemade window insert (we hadn’t had time to order one pre-storm) and placed the unit on a level table. In 95+ degree heat with no other relief, it obviously wasn’t strong enough to cool the room (that was not the expectation) but it did help keep that air that was moving cooler than it was without it.

I’ll be doing an experiment this weekend at my son’s regatta–the first real test of its power for camping purposes. We’ll be in the Sarasota sun all day, and I’ll be trying the unit inside a 1-x10 tent with a camping attachment that will enclose the space completely. I sewed a vent hole into the back of the tent structure for the exhaust. We have an external inverter battery that will power it since batteries cannot be ordered until everyone how initially ordered on gets theirs. Fingers crossed!


Steven June 5, 2018 at 4:23 am

Thanks for posting this I was curious about how the heat was exchanged. The venting of the heat exhaust creates the dreaded vacuum effect. Which draws in more warm air from outside which needs to be called and the more you use it you’re fighting a vicious never ending battle of causing the problem the machine is trying to solve.

This is why these are extremely inefficient and the worst performing and most power consuming air-conditioners on the market relative to their ability.

That said it’s still better than nothing and they work pretty well when the temperatures aren’t too high and cooling demand is small.

I’d still get one it’s better than nothing there’s nothing like it on the market. But it’s good to know that a cheap $99 window AC is better, just not portable.


Sandy February 26, 2018 at 11:27 pm

I would like to order a zero breeze but not sure how long it will take to get it. Does anyone know that since it’s been out for a year at least if it’s easier to get…or are they still filling the older orders.


Theodore Vincent March 29, 2018 at 10:18 pm

I own a zero breeze, I was running it on my car battery. It failed. I believe the refrigerant leaked out of the system.

I will sell it to anyone who is willing to pay $600 and shipping from San Francisco.

It is complete, I have the box, but support is asking me to send videos of the unit not working. It is obvious the refrigerant leaked I could smell it I saw it mist out and now everything works except the A.C. compressor.

They are probably too backed up to fix it…


Monique May 15, 2018 at 10:43 pm

I’d love to use one of these for a 3 to 6 month period and note variable differences. That is free of charge. I need something soon so spending that much with no reliable receipt date…is Zero Breeze trying to deter buyers? Why would anyone pay in full with no quick and reliable receipt? I would accept one to use foc. As for now I’m taking my money to some company that can deliver….soon!!!


Zero Breeze August 15, 2018 at 1:36 pm

Keith June 18, 2018 at 3:09 am

This AC unit did not work for us and the battery did not work at all. We tried to cool our small van and it did not even come close as a matter of fact the temperature went up. We contacted the customer support only one e-mail. They said they will not take returns!!!! So I am stuck with a really bad product and no help from the company. Very poor customer service. I told them I would tell every one I can how bad they are. So be sure this is what you want because they will not take it back!!!!!!


BYRON June 28, 2018 at 10:01 pm

do u think it would cool a small airplane


Geraldine Lippincott July 30, 2018 at 10:13 pm

Not sure, it will pull some moisture out of the air, lowering humidity, but you’ll have a pool of water on the floor and customer service will do nothing.


Zero Breeze August 15, 2018 at 1:32 pm

Hi Geraldine Lippincott
Could you show us the video so we can help you? Our support team email is:


Zero Breeze August 15, 2018 at 1:30 pm

How many square feet of area?


Zero Breeze August 15, 2018 at 1:26 pm

Hi, Keith
Could you send the battery didn’t work video to we’d love to help!
Most of the reason for not working are caused by wrong use.


dumbfounded June 2, 2019 at 12:42 pm

Hey zero breeze, what does square footage have to do with it? What does cfm mean to you ? You can’t possibly compare a tent, nor air plane, nor van, to a room with an 8′ ceiling. And what’s with telling people they can cool the outdoors??? Perhaps zero breeze should market these, claiming they will stop global warming!!! Lol.


Aswin July 5, 2018 at 1:12 pm

Really dissapointed.
I thought I landed to a real review of this product. Turn out this is just a marketing traps.
No temperature measurement, no stress-test, no figures of power usage…. just NOTHING.

Geraldine Lippincott July 30, 2018 at 10:11 pm

Leaks, and you’ll get no help from company. they just suggest to jack up the end where it leaks.


José A. Polo October 15, 2018 at 5:39 pm

Garbage. It’s a total deception. The machine is very heavy, it does not cool, it only blows air. The battery lasts less than two hours. They do not accept returns. Attention to the customer is only by email. Do not let them deceive you. I have already filed a complaint with the Better Business Bureau against this agency.


Rick Brown October 23, 2018 at 4:30 am

Am in Australia. Happy to buy a unit here with Australian warranty. I need for my boat using a 240v Honda EU22i geni. and cooling a very small cabin through a window on the deck so condensation runs away and the unit is drawing and exhausting from outside.

Aussie Race


Camper sydney December 12, 2018 at 1:05 pm

Still waiting for mine to arrive in Sydney. Late arrival. Didn’t arrive when it was supposed to, so stayed in hotel. $480 down so they offered $100 off if I buy a new one. Hopefully it turns up soon. Below average service so far. Let me know if your one arrives Rick and how it works in your boat. I’ll be using in camping van. Fingers crossed.


David Swingle March 31, 2019 at 4:22 am

not sure if this has been addressed. The company advertises it as an outdoor air conditioner, ive sat outside in 90 degree heat fishing with the zero breeze sitting on a camping table next to me keeping me cool and comfortable. the 50 square feet thing is just an anecdote. it was never meant to cool a room or space no matter how small. its meant to keep you cool outside in the heat. it works great for that. outdoor AC, awesome!


alex April 1, 2019 at 1:16 am

Don’t buy this folks, its claiming to break the fundamental laws of thermodynamics (shockingly, it cannot). Air conditioning works in one specific way: absorb heat from inside and move that heat outside. Given that this product has no exterior piece to move the heat outside.. it doesn’t cool anything. In fact, it will actually make the area warmer by powering a compressor and fan without any external exhaust..


Roy May 8, 2019 at 2:41 pm

Battery is defective upon receipt. Zerobreeze made empty promises to send a replacement battery but never did. Pls be mindful and not support such dishonest people.


Rick June 7, 2019 at 1:54 pm

My experience…ordered product, with battery backup, paid for 5 day shipping. Received product a month later. They did refund my 5 day shipping fee. Started unit and it only blows room temp air. All lights and indicators operate as advertised. Contacted zerobreeze about the problem via email (only way to communicate with them in China). Their web site says they will respond within 24 hrs. 5 days later they asked for photos/videos showing to problem. I complied, sent detailed videos back to them. 10 days later I have not heard anything from them in spite of multiple follow up emails. The product might actually be ok (of course mine doesn’t work at all) but customer service is absolute garbage. If they ever get back to me I’ll post the outcome. As of now I only have an $800.00, very low volume, room temp fan and no idea if I will ever hear from the seller again.


CPL June 25, 2019 at 3:59 pm

Same experience as Rick – total crap. Has not worked from day 1. Met the demands for video after video of the machine NOT blowing air any cooler than ambient room, even after it running for over 45 minutes as the pathetic, delayed email responses demanded. Now I am not getting responses to the request for return shipping instructions to get a refund for this non functioning machine. I am 6 weeks into the heat, down $1,199, and have no cold air from this hunk of junk.
