I haven't had a problem with it yet and I've been doing it for quite a
few years now... Regardless, I also have an 8Ah battery pack that I
built that has a lighter plug on it also... I usually use it to power
my PDA w/GPS so that I'm not completely dependent upon the internal
batteries in it... Sometimes I'll also use it to power my laptop, but
considering the fact that the laptop probably takes 50W, the 8Ah
battery would give me less than 2 hours of full power use out of it...
If I leave the display on the laptop closed except when I need to
refer to the moving map on it, I suspect that it will last quite a bit
longer... All in all, I tend to prefer not to leave these plugged into
the aircraft's lighter port...
