I'm looking for a power inverter to use it primarily to power up a vacuum cleaner in the car.
The vacuum is 550 Watts.
There are power inverters 600+ watts, but they are a bit more expensive and looks like they cannot be plugged in to the cigarette socket (only to the battery directly, which is not practical for cleaning at all).
But there are other inverters which are, for example, 400 watts continuous / 700 watts peak.
So I would like to know what that 'peak' characteristic is and also can I use the 400/700 watt inverter to power up my 550 watts vacuum.
