In detail: Evapolar evaCHILL Personal Air Cooler
The Evapolar evaCHILL belongs to the family of personal evaporative air coolers, a compact and affordable alternative to a conventional portable air conditioner. The principle is simple: a built-in fan draws the surrounding air through an EvaBreeze cartridge made of basalt fibre, soaked with water drawn from an 800 mL tank. As this water evaporates, it lowers the temperature of the air being blown out, with no compressor or refrigerant gas, for natural cooling within a radius of about one to one and a half metres.
Its USB power supply, rather than a standard mains plug, means it can be connected to a computer, a USB wall outlet or a power bank (at least 5V/2A), for immediate setup on any desk with no dedicated outlet nearby. Its power draw stays minimal, 7.5 W maximum according to Evapolar, up to 100 times less than a conventional portable air conditioner. The 800 mL tank provides up to 9 hours of continuous runtime, depending on which of the four fan speeds is selected.
With its ultra-compact footprint (17 x 17 x 17 cm, about 770 g), the evaCHILL sits on a corner of a desk, a bedside table or a countertop without taking up space. It suits strictly individual use: unlike a portable air conditioner, it does not cool an entire room but only the space close to the unit, in the direction of the airflow. The EvaBreeze cartridge also traps large dust particles, a welcome purifying bonus.
The limitation most often mentioned by users concerns effectiveness in already humid air: like any evaporative technology, cooling loses intensity above 60% relative humidity, worth knowing before buying, especially in an oceanic climate or during stormy summers. The average buyer rating (3.6/5 from several thousand reviews) reflects this dependence on local climate conditions, with some users in humid climates left disappointed with the result.
For desk, bedside or on-the-go use in a dry to moderately humid climate, without the budget or setup of a genuine portable air conditioner, the Evapolar evaCHILL remains an economical, quiet and easy-to-carry stopgap solution.

Frequently asked questions: Evapolar evaCHILL Personal Air Cooler
It draws in the surrounding air through an EvaBreeze cartridge soaked with water drawn from an 800 mL tank: as this water evaporates, it lowers the temperature of the air blown out, with no compressor or refrigerant gas, giving a cool airflow within a radius of about 1.5 metres.
A portable air conditioner uses a compressor to genuinely lower the temperature of an entire room, whereas an evaporative cooler like the evaCHILL only cools a personal space close to the unit, with far lower power consumption.
The 800 mL tank provides up to 9 hours of continuous runtime depending on the fan speed selected, easily enough to cover a full workday or an entire night.
No: its power draw does not exceed 7.5 W, compared with several hundred watts for a conventional portable air conditioner, which also means it can be powered from a simple power bank or a computer's USB port.
Less so than in dry air: like any evaporative technology, its effectiveness decreases above 60% relative humidity. This is the main limitation reported by users in an oceanic climate or during stormy summers.
