Question about Jackery Explorer 1000 Pro

"The fan has several levels, with the lowest level starting at less than 100W (I can't say for sure). I have also noticed that it is not only dependent on the power but also on the ambient temperature, i.e. the ventilation starts sooner in warm weather. However, it can be said that the ventilation is quite quiet, apart from the maximum ventilation when charging with approx. 700W."

At 400 watts the Venti runs very quietly, at 800 watts it is clearly louder. I have installed the 1000 pro in the bus. 2 solar cells (180 watts each) feed the Jackery. We cook with induction and the Dometic fridge is always running. The Jackery is usually so quiet that we never hear it. We are delighted with the 1000 pro.

In my case it is about 2000 watts (induction hob). The fan only starts up for a long time when charging from the can. You can only hear the fan quietly outdoors. I can't say exactly when it starts up. In any case, it doesn't bother me.
