A survey of smaller angle grinders on amazon says they're typically 6-7.5 amps, which is about 700 watts.
A car battery can certainly deliver this much current (they can typically do stuff like 6600 watts for short periods of time) but few inverters can do this much (a "regular" one is probably around 100 watts, and you can get others that do more. A 750 watt inverter can be had for only $50!). You'd have to clip it directly to the battery directly, since cars typically have a fuse on the cigarette lighter that will certainly not let 700 watts through.
How far is it from an outlet?
Surely some burner around there has a generator or deep cycle marine battery and high capacity inverter you could borrow!
