Data sheet
A fan does not have the same function as an air conditioner. It does not lower the temperature of your room. The feeling of freshness provided by the fan comes from the air blowing on the micro-droplets of water due to perspiration, which we have on the skin. By evaporating, these micro-droplets cool us down.
Yes, our table fans consume very little energy. There will of course be an impact on the autonomy of your laptop, but it remains acceptable.
If your product works with a remote control or touch buttons, this is probably not possible. On the other hand, for fans with mechanical buttons or dimmers, it is normally possible. Before plugging it into a timer or a connected socket, you can do a simple test: turn on your fan, unplug it for 30 seconds and see if it starts again by plugging it back in.
A fan will only circulate the ambient air, whereas an air cooler will also help to lower the temperature in your room by a few degrees by humidifying the air.
If the appliance whistles, it is time to clean it: dust may be accumulating inside the appliance. Start by cleaning the grille on the back using a vacuum cleaner. If the whistling noise persists, undo the screws and remove the grille. Vacuum the interior grille and wipe it with a soft cloth if necessary.
