Heading out in your RV is all fun and games until the sun decides to turn your cosy home on wheels into a mobile sauna. If you’re searching for the best portable air conditioner for a caravan in Australia, the reality is that not all units are created equal. Especially when you factor in power draw, space and whether you’re running off-grid.
Some are designed to cool people, not rooms. Others can actually bring down the temperature inside your van, but at the cost of higher power demands and more setup.
Below, we break down five portable aircon options so you can figure out what actually suits your setup. We’ll start with this quick summary table, but you can scroll down for more details about each portable air conditioner.

The best portable air conditioner for a caravan in Australia depends on your setup. Lower-draw units like the Kings Portable Air Conditioner and the EcoFlow WAVE 3 are popular for off-grid use, while larger caravans typically need higher-capacity systems to cool the entire space.
Most portable air conditioner units will not have enough grunt to lower the temperature in a large caravan, hence a built-in system will usually be required. However, if you have the option to close off your bedroom area from the rest of the caravan, then one of these portable options could still be a workable choice.
BTU measures how much heat an air conditioner can remove from a space. A higher BTU rating generally means more cooling power, but in a caravan, insulation, airflow, direct sun and the size of the space all matter. A portable unit may work well in a compact caravan, camper trailer or van build, but it won’t perform like a full rooftop air conditioner in a large rig.
Best for: Camper trailers, swags, rooftop tents and small caravans with a suitable power setup.
The Kings Portable Air Conditioner has quickly become one of the more talked-about options in the touring space, mainly because of the price and low power draw.
Unlike personal cooling units, this is designed to cool small enclosed spaces, making it a much more practical option for camper trailers, tents and compact caravans.
With around 5100 BTU of cooling power and a relatively low 500–600W power draw, it’s one of the more realistic options for travellers looking to run air conditioning off a battery and inverter setup. That said, you’ll still need a decent system behind it, with Kings recommending a 2000W inverter or higher.
It runs on 240V power and includes ducting and adapters out of the box, so you can set it up for different environments depending on your camp setup.
Like most compressor-style portable air conditioners, it does require venting, and performance will depend heavily on the size of the space you’re trying to cool.
It’s not designed for large caravans or motorhomes, but in smaller spaces, it can take the edge off the heat and make sleeping far more comfortable.
Best for: Rooftop tents, swags and very small enclosed spaces (like a teardrop caravan).
The KickAss 400W Portable Air Conditioner is aimed squarely at travellers who want a compact, low-draw cooling option that can realistically run off a modest off-grid setup.
With around 3100 BTU of cooling capacity and a max power draw of roughly 430W, it sits below larger units like the Kings or EcoFlow options in outright performance, but makes up for it with efficiency and portability.
This makes it a good fit for small, well-contained spaces like rooftop tents, swags and tiny campers, where even a small drop in temperature can make a big difference to comfort.
It also comes as a complete package, with ducting included and simple touch controls via an LED display, so setup and operation are fairly straightforward.
Like all portable compressor-style units, it still requires venting, and you’ll need to account for start-up power, which can spike higher before settling into normal operation.
It’s not designed to cool a caravan or larger enclosed space, but for lightweight touring setups chasing a more realistic off-grid cooling option, it ticks a lot of boxes.
Best for: Small to medium caravans, van builds, and travellers wanting both cooling and heating in one portable unit.
The EcoFlow Wave 3 Portable Air Conditioner is the latest evolution in EcoFlow’s portable cooling lineup, and it’s clearly aimed at travellers who want something more capable than personal cooling units without jumping straight to a full rooftop system.
This unit doesn’t just cool – it also heats, making it a more versatile option for year-round travel. With 6100 BTU of cooling and 6800 BTU of heating, it’s designed to handle small to medium enclosed spaces like caravans, camper trailers and van builds.
EcoFlow claims it can drop the temperature by around 8°C in 15 minutes, or warm things up just as quickly when the weather turns, which makes it one of the more powerful portable options in this category.
Like the rest of the Wave range, it’s built around flexibility. You can run it on mains power, or pair it with EcoFlow’s add-on battery and broader ecosystem for off-grid use. With the optional battery, you’re looking at up to 8 hours of runtime, depending on conditions.
Control is handled through the EcoFlow app, where you can adjust temperature, monitor battery levels and even receive alerts when the unit needs attention – like draining the water tank.
It’s not a cheap option, and it still requires venting like most compressor-style units, but for travellers chasing a more complete portable climate solution, it’s one of the most feature-packed options currently available.
Best for: Personal cooling when sitting or sleeping in one spot.
The Coolzy-Pro Personal Portable Air Conditioner is designed to keep things simple, offering a plug-and-play cooling solution without the need for ducting, installation or window kits.
Unlike traditional portable air conditioners, the Coolzy-Pro doesn’t aim to cool an entire room. Instead, it creates a focused stream of cool air, effectively cooling the person sitting in front of it rather than the surrounding space.
This makes it a practical option for caravans, tents or small areas where you’re staying relatively stationary, like when you’re sitting at a dinette or sleeping in bed.
One of the big advantages is its low power consumption. Drawing around 300–340W, it’s significantly more energy-efficient than compressor-style units, making it easier to run off smaller off-grid setups with the right inverter.
It also comes with a few added features over the base model, including three fan speeds, temperature control and a remote, giving you more flexibility in how you use it.
That said, it’s important to set expectations. This isn’t going to bring down the temperature inside a caravan – it’s designed for personal comfort, not space cooling.
Best for: Off-grid camping setups, tents and small spaces where portability and battery use are priorities.
The Zero Breeze Mark 3 Portable Air Conditioner is designed with portability and off-grid flexibility in mind, offering a more self-contained solution compared to traditional portable air conditioners.
With 5280 BTU of cooling capacity, it sits in a similar performance range to units like the Kings, but differentiates itself with a more compact and lightweight design, coming in at around 10kg.
Like the EcoFlow Wave 3, one of the standout features of the Zero Breeze Mark 3 is its ability to run on battery power (sold separately), with support for solar charging and vehicle inputs, making it a strong option for travellers who want cooling without relying on mains power.
It also includes a dual-hose venting system, which improves efficiency compared to single-hose designs, helping it cool small enclosed spaces like tents, swags and compact campers more effectively.
The Mark 3 also adds heating capability, multiple operating modes, and an active drain system that automatically manages condensation, reducing some of the usual setup hassle that comes with portable units.
While it offers a lot of flexibility, it’s still important to understand its limitations. While Zero Breeze doesn’t specify a fixed room size, its output and design place it firmly in the small-space category. Like most portable units, it’s best suited to small, well-contained spaces, rather than larger caravans or motorhomes.
Yes, but the right unit depends on the size of your caravan and your power setup. Some portable air conditioners are designed for personal cooling, while others can cool small enclosed spaces.
For small caravans and camper trailers, options like the Kings Portable Air Conditioner, Zero Breeze Mark 3 and EcoFlow WAVE 3 offer stronger cooling than personal coolers. For direct cooling, the Coolzy-Pro may be enough.
Yes, but you’ll need enough battery capacity and a suitable inverter. Some units also offer add-on batteries or solar charging options.
Usually not. Portable air conditioners are best for small caravans, camper trailers, van builds, tents and compact spaces. Larger caravans generally need a rooftop air conditioner.
BTU measures cooling capacity. The higher the BTU, the more heat the unit can remove, but caravan size, insulation and outside temperature all affect performance.
