CENSTECH GY-A835 Portable Evaporative Air Cooler, 900 ml

Portable: The CENSTECH GY-A835 is a compact, USB-powered evaporative air cooler with fan, mist, cooling and night-light functions. Its listing describes a tabletop unit for personal use, with three speeds and a 900 ml water tank. It adds moisture to the air, so it is better understood as a personal cooler than a replacement for conventional room air conditioning.

At a glance

Four functions listed: fan, humidifier, evaporative cooler and night light.
Three fan speeds and two mist modes, with a claimed boost mode.
USB-powered operation and a 100 cm USB cable are stated in the listing.
The 900 ml tank is claimed to provide up to 10 hours of cooling. That duration is a manufacturer claim, not an independently confirmed runtime.
