hmm so if you run you generator the inverter on that is going to blow up also?
yes you should never run a higher draw than your altanator can handle.. and if the car is running you will never have to worry about drawing down your car batery. Also Car/truck altanators are designed to run 100%, thats why we have voltage regulators to prevent them from frying your batteries.. but you did raise a valad point.. if you try run over your altanators rating you can suck down your battery as it will act as a reserve.. also you could overheat your voltage regulator and cause some problems but most likely.. you will blow a fuse long befor then. We used to run a welder off the truck battery.. now you want to see something that will suck a battery down LOL
*disclamer* sometimes stuff fails when it shoulden't, the world is a imperfect place.. so of course if you can aford to get a genarator and such, "the biger the better" applies here.. but if you can't use some comen sence.. don't obver size your draw for your power supply weather it be a car or a generator.
Read the sticker on the inverters you buy.. when it says 600 watts is that continuios or peek (don't worry Adam the one you got was continuios something like 1300 peek) so if it says 600 continious stay under that to be safe.
