Yes, you can use a portable air cooler outdoors, for example on a covered patio or under a tent, but the effect is smaller than indoors because the wind blows the cool air away. Make sure the device is dry and stable, out of reach of rain and splashes, and place it close to yourself. An air cooler works best in warm, dry air.
Does an air cooler work just as well outdoors as indoors?
An air cooler cools by evaporating water and blowing that cooler air towards you. Outdoors, there is no enclosed space to cool down; the cooling is limited to the immediate vicinity of the device, and the wind quickly disperses the cool air. So you will mainly notice the effect if you are sitting right next to it, for example at a table on a sheltered patio. In warm and dry weather, the evaporative effect is greater than in stuffy, humid air. Read more about this in how an air cooler works in high humidity.
What to pay attention to when using it outdoors?
An air cooler is an electrical device with a water tank. Therefore, keep it out of the rain and away from a garden hose or sprinkler, and place it on a stable, flat surface so that it does not fall over and the tank does not empty. Preferably use it under a canopy, parasol, or tent. Do not place the device in direct sunlight and only refill it with clean water. Make sure the electrical parts and the charging port stay dry and charge the device indoors.
| Situation | Suitable? | Tip |
|---|---|---|
| Covered patio or veranda | Yes | Place it close to the seating area, out of the wind |
| Tent or caravan awning | Yes, with precautions | Keep the device dry and stable |
| Open garden with a lot of wind | Limited effect | Place it sheltered and close by |
| Rain or wet grass | No | Use indoors or under cover |

Direct answer: yes, you can use a portable air cooler outdoors on a covered, windless patio or under a tent, as long as it is dry and stable. The effect is smaller than indoors and it works best close by and in dry, warm air.
