This portable cooler features a water-cooling system with ice cubes for an 8–10°C drop and a 3-second cooling blast, yet runs as quietly as 30 dB for undisturbed sleep. Set the 1, 3, or 6-hour timer to auto-off, while the filter traps dust and the large 470ml tank with ice compartment provides long-lasting humidified refreshment. Touch controls offer simple, responsive operation in a sleek design.
