Key Features

What makes Hi-Cooler special?

No Greenhouse Gases

Hi-Cooler utilizes a water evaporation cooling system, which is 600x more powerful than water cooling. This water evaporation system will not generate hot air or any other greenhouse gas during the cooling process, making it one of the most eco-friendly air conditioning options currently on the market.


Hi-Cooler is powered by a standard, swappable battery. With its power usage of <10 Watts, which is just 1% of traditional air conditioner power usage, energy costs are substantially reduced. In addition to a standard battery, Hi-Cooler can also be powered by a USB 3.0 charger, further reducing any battery costs.


Hi-Cooler is small enough to sit in the palm of your hand, or stand as a small accessory on your desk. In addition to its small size, because it is battery powered, it does not need to be plugged into an outlet in order to function. You can put it in your purse, or even your trouser pockets, to bring to your destination.


Unlike traditional air conditioners, which are extremely dehydrating after long periods of cooling, Hi-Cooler’s water evaporation method provides a hydrated cooling, and therefore, softens the skin and moisturizes the eyes and throat.

Case Studies

We tested the cooling capabilities of Hi-Cooler in both outdoor and indoor settings. The following results were recorded using an AZInstrument 8918-Thermo-Hygro-Anemometer.

In all cases, the water tank built into Hi-Cooler is sufficient for providing 20-30 mins of emission-free, low energy consumption cooling.

Outdoors: 32°C to 26°C

In an early testing at an outdoor park, recorded at 31.3 degrees Celcius, Hi-Cooler was able to lower the surrounding air temperature to 25.6 degrees Celcius in approximately 2 mins.

Indoors: 27°C to 22°C

When tested indoors, Hi-Cooler was able to provide cool air in a room, recorded ambient at 27 degrees Celcius, to 22 degrees Celcius in approximately 2 mins.

Where to Use

Hi-Cooler was created because air conditioning has become a necessity, rather than a luxury, within today’s global warming climates. Hi-Cooler’s eco-friendly, portable and hydrating cooling design means that its application spans across residential and industrial uses, and is suitable for both the young and old.

Go in-depth about how Hi-Cooler functions
Hi-Cooler is a reinvention of the traditional Evaporation Air-Conditioner to increase the evaporation efficiency to the highest level.

In the new system of Hi-Cooler, we remove the pump and media, and replace the open mouth water tank with a sealed water tank that build-in a mister. Then we carefully control the size of water molecules, amount of water molecules and the air flow so that the evaporation reach the highest efficiency. Therefore we can use minimal water to provide maximum cooling power.
