Operation is simple and completely silent, if not a kind of "boing" inconsequential has power.
The 2 types of plug US / France (with earth) are output but the power cable has a French socket + earth 2 records.
Of course, these are windings on the inside and it is very heavy (> 5 lbs): it is better not to foresee the move too.
Finally, a small note in my electrician: it is advised to foresee a converter 1.5 has 2x more wattage than the most greedy device has power (for example, for a device is 100W, predict a converter 150 to 200W, or more). I have such a KitchenAid American 900W plugs into a 2000W inverter.
Cheers!
