Yes true, the fan runs constantly and is also not very quiet, but perfectly acceptable for the gelegenliche benefits in the camper. To have opened without the device, I suspect that the stylish aluminum housing is not really cooling support (Aluoberseite is only loosely connected with the rest of the housing, so that no good heat dissipation possible), and the fan must therefore constantly run along. If you set the device to the rear or the footwell of the motor home, the running noise does not bother. Ideally suited for EeeBook, as well as tablet, shaver or cell phone; more consumers were not plugged in.
Negative: No rubber feet, therefore Virbationen be like to transfer on slippery ground, and no max. Power rating noted.
Quality design when the machine stops, it has a great value for money
