Australian customers awarded Coolzy best portable air-conditioner for 2022.
Coolzy produces more intense local cooling than traditional portables.
Coolzy is the only truly portable cooling solution.
Coolzy is much quieter, smaller, lighter, and provides the lowest cost, most environmentally responsible cooling solution in the world.
Read more to understand why Coolzy is able to provide the best portable cooling solution.

A wall-mounted split air-conditioner creates 12,000 BTU every hour, enough to cool a 12 square metre room by 10 – 12 °C (18 – 22 °F).
1,000 BTU cooling per spare metre.
The wall unit cools room air and transfers heat to an outdoor unit with a compressor and fan.
The fast-moving cool air mixes with room air and spreads through the room.
The air-conditioner draws about 900 – 1,200 Watts electricity.

A normal portable room air-conditioner creates 12,000 BTU cooling every hour and draws about 1,200 Watts electricity.
However, it provides much less room cooling, only 3 – 4 °C (5 – 7 °F).
Why?
A: About 2,700 BTU offsets heat radiating from the hot exhaust pipe.
B: About 6,500 BTU offsets heat from outside air sucked into the room. This air replaces the room air sucked into the machine and pumped outside through the pipe.
C: Only 2,600 BTU remains to cool the 12 square metre room: 220 BTU per square metre, one quarter the room cooling from the split AC.
(numbers change slightly, depending on temperature, humidity, window kit installation, door opening, building structure, and the characteristics of the aircon model)

Coolzy creates about 3,500 BTU cooling every hour and uses only 340 Watts electricity.
Coolzy focuses the cooling on one or more people nearby, over 4 square metres maximum floor area. That’s nearly 900 BTU per square metre, so the cooling is four times more intense compared with a portable AC.
The small amount of warm air rises to the ceiling, just like warm air from your kitchen refrigerator. It escapes through the open window (or doorway).
The cool air jet provides up to 3,000 BTU per square metre cooling intensity at one metre distance.
The apparent cooling inside the optional Igloo tent is 8 – 12 °C (14 – 18 °F), much the same as with a split air-conditioner, but with 70% – 80% less electricity.
Now consider size, weight, noise and the total cooling cost.

Coolzy is smaller, much lighter, and easy to carry. You can use it anywhere, even outside in sheltered places.
A normal ‘portable’ air-conditioner is too large and heavy to carry without help, and must be near a window or doorway.
A ‘portable’ air-conditioner makes about the same noise as a kitchen juicer. It is too loud for most people to sleep with.
Coolzy makes much the same sound as an electric fan, ideal for sleeping.
When and where do you need cooling?
A split air-conditioner is great for cooling a crowd.
However, using a split AC all the time costs more than most families can afford, and you install one for every room where you need cooling (or heating in winter).
Coolzy is great for one or two people sleeping.
Coolzy is fine for chatting or watching TV together.
Coolzy is great for working at a desk or in a large space like a warehouse.
Coolzy allows cooling and privacy.
There’s no need to be in the same room as everyone else to be cool.
Coolzy is the only truly portable cooling solution.
What’s the total cost?
For nine months cooling, Coolzy costs just $400 a year including purchase repayments and electricity.
For nine months cooling, each single split air conditioner costs about $1,400 – $2,000 a year including purchase repayments, installation, and electricity.
A portable air conditioner provides much less cooling, and still costs $800 a year, of which 80% is the cost of electricity.
Coolzy is the least expensive, simplest, most sustainable cooling solution.
