Hi there,
i was wondering if it's safe to charge my x220 while in car using one of those 12v o 220v inverters/converters or it' not a good idea?

No problem -- just make certain the inverter is rated to put out at least 75 Watts continuous, i.e., you could manage with a unit half the size of what you show, if "compactness" matters to you, such as:

well, the one i have says upto 150watts but i am not sure if contiunuesly. BTW can I damage the laptop if wattage not enough or too much?
