How does an evaporative cooler differ from an air conditioner?

It cools by blowing air over water and ice, adding moisture to the air. It does not use refrigerant or vent heat outdoors, so it lowers the temperature only a few degrees and works best in dry air.

How long does the tank last?

The 600ml tank gives up to 6 hours of runtime, less on the highest speed. You refill from the top and can add ice cubes for colder air.

Can I use it in a humid room?

Evaporative cooling depends on dry air, so it does little in a humid room. In muggy conditions it works mainly as a fan and humidifier.

Does the timer turn it off automatically?

Yes. The timer can be set to 2, 4 or 8 hours, then the unit shuts off on its own.

What comes in the box?

The cooler unit itself. Check the listing for any included accessories such as a power adapter before buying.

Can it cool a whole room?

No. It is a personal cooler meant to sit close to you, on a desk, nightstand or tent floor, and cool the air in its immediate path.

Our take on the Portable Air Cooler 4-in-1

The AsterOutdoor Portable Air Cooler 4-in-1 is a small evaporative cooler that also works as a fan, a humidifier and a seven-color night light. It has a 600ml top-fill tank that takes ice cubes, three fan speeds, a 2/4/8-hour timer and up to 6 hours of runtime. It suits a desk, bedside table or tent where a full-size swamp cooler won't fit. Against larger evaporative coolers it moves far less air and holds much less water, so expect spot cooling of the air right in front of it rather than room-wide relief.
