CoolingAce Personal Evaporative Cooler

CoolingAce is a personal evaporative cooler — small enough for a desk or nightstand and powered by any USB port. It pulls air through a water-dampened cartridge, so the air reaching you comes out cooler and a touch more humid than the dry, hot room around it.

CoolingAce is an evaporative cooler, not an AC unit: It cools the pocket of air in front of it — not a whole room — and works best in dry heat. In very humid weather the effect is gentler.

• Runs off any USB port (laptop, wall plug or power bank)
• Top-fill water tank — hours of cooling per fill
• Multiple fan speeds, quiet operation
• Light enough to move room to room
