Yes, thats the type of inverter I was talking about. (Although I have a US version, of course.)
I have a similar one that is 200 Watt with 2 outlets plus a USB outlet. It's great to use in the car while traveling, for charging camera batteries, cell phones, laptop computers, whatever you need to charge. it eliminates the need to buy a special car charger for each item.
My laptop charger cord is long enough that the laptop can lie safely in the back floorboard while charging.
