  • Long battery life
  • Lighter and smaller than other portable ACs

Cons

  • Expensive
  • Loud

When you find yourself needing more cooling than what a fan offers and a regular air conditioner is just not possible, then consider getting a portable AC unit. And if you’re in the market looking for one, here’s a product you might want to check out – the Zero Breeze Mark 2.

Mark 2 is a follow-up on the highly successful crowdfunding campaign, Zero Breeze, which received more than US$1,600,000 of funding on both Kickstarter and Indiegogo. After 3 years, the same company released the second version, which received around US$905,000 through crowdfunding.

How is it different from the previous model and how does it compare to other portable air conditioners in the market? Let’s find out with this review. Can’t read the whole thing? Click on any of the links below to skip to that section.

Overview

Air conditioners are one of the best inventions ever. With the extremely high temperatures, such machines are a lifesaver. However, there are times when installing an air conditioner isn’t always practical, especially if you’re living in an apartment. And with the size, functionality, and weight of existing portable air conditioners, going outdoors is out of the question – well, until now.

Zero Breeze Mark 2 is a portable air conditioner that may just be the solution for your summertime heat problem. It is smaller and lighter than most traditional portable air conditioners, which makes it easier to carry on your trips and adventures. Plus, it’s a true AC – which means no water or ice is required.

In terms of price, however, the Zero Breeze Mark 2 is expensive. The Basic package, which does not include a battery, already costs US$949 on the company’s website. The Plus, which comes with 1 battery, costs US$1399 while the Plus Extra with 2 batteries costs a hefty US$1799. This is a lot pricer than some of the top portable ACs around. To give you an idea, the Whynter ARC-14S costs US$521, evaCHILL at US$99, and the No products found..

Zero Breeze Mark II See Through

Features

Multiple Power Options

The Mark 2 runs by either a battery or wall power. If you are near a wall outlet, say in your home or cabin, then you can just plug the 240W power adapter and immediately start cooling the area. However, if you are going outdoors and no outlet is available, then you can use the unit’s battery. Each battery can run an impressive 3 to 5 hours, depending on the mode of your choice. If you didn’t purchase the Zero Breeze battery, you can also use your own 24V battery supply.

Cooling Effect

The most important feature of an air conditioner is its cooling effect. Regardless if it’s battery-powered or portable, it won’t be of use if it can’t bring the temperature down.

With the Mark 2, it actually does work. Without putting in water or ice, this portable AC can spit cold air instantly. However, keep in mind that the Mark 2 isn’t a regular AC unit that’s designed to cool your entire home. With its 2,300 BTU rating, it may even have a hard time cooling down a cabin, especially during the daytime when the temperature is at its peak.

But for smaller and sealed spaces (20-40 sq. ft.), the Mark 2 can impressively deliver quick and more sustained cooling. In fact, it can drop the temperature up to 30°F lower than the ambient temperature in just 10 minutes. Also, under more favorable instances (if the insulation is very good or it is nighttime), the Zero Breeze 2 can be a good cooling option for a cabin.

Extension Pipe

An extension pipe is included in the Mark 2, which you can use to quickly blow cold air towards you. This is perfect for compact spaces so the unit won’t be restricted by its placement.

Dump Protection

In case of complicated outdoor environments, the Mark 2’s built-in dump protection mechanism will turn off the device to prevent any damage to the system.

Dual-Hose Heat Dissipation Pipe

The Mark 2 can quickly transfer heat out of an enclosed space through its dual-hose heat dissipation pipe. This allows the device to cool a space more efficiently.

Noise Level

One of the things people look out for in an air conditioning unit is its noise level. And it’s perfectly understandable since you’d want to be able to sleep comfortably while it is on. With Mark 2, however, that’s not exactly the case. Its rated noise level is 52dB, which is about the same noise your fridge makes. That’s bearable, in theory. But if you’re in a small tent with the unit in the highest setting, the noise would be much louder and almost deafening. Thankfully, Mark 2 has a Sleep Mode, which is quieter and perfect for nighttime and sleeping.

Multifunction

Now, the Zero Breeze Mark 2 isn’t just an air conditioner. It’s also a fan with a light, making it great for hot summer getaways.

The Zero Breeze Mark 2 has a lot of significant improvements from its predecessor. For one, it is more powerful with a higher BTU rating of 2,300 compared to Mark 1’s 1,100 BTU. The newer model also has 2 hoses from one and can now cool much faster.

Compared to other portable ACs, Mark 2’s BTU may seem quite small. The LG Dual Smart Portable Air Conditioner has a 10,000 BTU and the Whynter ARC-14S has 14,000 BTU. Both, however, are pretty huge, do not work without a wall outlet, and are equipped with wheels. Compared to more similar products – in terms of size – Zero Breeze is superior. For instance, the evaChill has a 340-1,190 BTU, while the evaSmart has 340-1,360 BTU.

24V Power Adapter Specification

The 24V power adapter is necessary if you want to use the unit without the battery. This will give you unlimited cooling time. If you’re going to use the battery, you will have to attach it to the unit with another cable. To charge the battery, you will then have to disconnect it from the unit and attach it to another huge AC adapter. Now, this isn’t complicated at all. But it does mean you’ll have a lot of gear to deal with.

Mark 2’s portable battery takes 4-5 hours to charge fully. You can use a wall outlet or if you’re outdoors, you can use in-car charging or solar panels. Unlike its predecessor, you can also use the battery to charge your other devices via USB ports. You can even use it for your power-hungry laptop, which is pretty great.

Zero Breeze Mark II Camping Use

Aesthetics

The biggest feature of the Mark 2 is its design, particularly its portability. Unlike most “portable” air conditioners in the market, the Mark 2 does not have any wheels. It does have a handle, which you can use to move the unit from one point to another. If you purchased the battery, you can combine it with the AC and carry them as one unit. It will be heavy, but still manageable even with one hand.

While the Mark 2 is larger than what we expected, it is still a lot smaller and lighter than anything we’ve found – except for the Evapolar products.

Conclusion

Compared to its predecessor, the Mark 2 has more features, functions, and power. With its cooling efficiency, long battery life, and design, Zero Breeze Mark 2 is a true portable air conditioner. While it is a bit heavy and larger than we’ve expected, it is still among the most portable yet powerful units you will find. So overall, this is the best portable AC for travel, camping, fishing, trailer, and your RV.

Keep in mind, however, that the Zero Breeze Mark 2 isn’t perfect. It is loud and expensive. Plus, it’s only ideal for smaller areas. But as far as portable ACs are concerned, the Zero Breeze Mark 2 is a great choice to keep you and your beloved pet cool during extremely hot weather conditions – that is, if you’re willing to overlook the hefty price tag.
