Our Verdict
This is our top personal cooler. Smart control, very low power use and USB power make it easy to use at a desk, in a car or on a camping trip.
It cools one person within a few feet and works best in dry air, so it is not a substitute for a room cooler or air conditioner.

Design
Evapolar’s patented evaBreeze cartridge, made from long-lasting basalt fibers, cools and humidifies the air. You feel the breeze within 3 to 5 feet in the direction of airflow.
It has a removable water tank and a full-spectrum LED light, and it is compact enough for a desk, nightstand or tent.
Controls
You can run it from the mobile app or through smart home services, so it fits into routines with your other devices.
It consumes only 12.5W and can be powered by USB from a power bank, laptop or car outlet rated at 2.5A and 5V.
Placement Tips
Place the cooler near an open window or door, or with a window cracked on the far side of the room, so dry air can come in and humid air can escape. Aim the airflow at where you sit, sleep or work rather than into a corner.
Evaporative coolers work best in hot, dry weather. On humid days, switch off the pump or water mode and run the fan alone, since adding more moisture to damp air makes a room feel sticky rather than cooler.
Running Costs and Care
An evaporative cooler draws far less power than an air conditioner, so running costs are low. Budget for water and an occasional replacement pad instead of a big electricity bill.
Drain and rinse the tank regularly so water does not sit stale, and clean or replace the cooling pad as the maker recommends. Before storing the cooler for winter, run the fan without water so the pad dries completely and does not grow mildew.
How It Compares
Against the Evapolar evaCHILL, the evaSMART adds app and smart home control and a full-spectrum light.
Against the Arctic Air Pure Chill 2.0, the evaSMART adds smart control and USB power, while the Arctic Air uses even less power and costs far less.
