Eernest,
How do you attach an dc/ac converter to an alternator? Or is there something that I could buy to run it through the car's cigarette lighter?
Actually, depending on the model that you buy, I seen some on the internet that just clamp to the pos & neg battery terminals, like jumping a car battery with cables.
They also have some smaller units that plug into the cigarette lighter, but those would be too small to power an electric chain saw. The inverters that do power a chain saw ran around $179.oo to 250.oo price range, but its a handy item to have to run any electric power tool when you without electricity or even to keep a pellet stove running in a power outage or your central oil burner , for that matter.
Back in the 1970 is see one that bolted up to the back of the altinator & I suspose that
www.jcwhitney.com has a bunch for sale. also look at

If you are going to use it for an electric chain saw , read the lable of the saw & look for the wattage the saw uses, if you cant find that,look for the current in amps or amperage and the voltage Vac
P=E x I
power,in watts= voltage x amperage
You need to buy a dc to ac inverter that is powerfull enough to supply the tool you want to opperate & have some extra capacity left so that you dont end up frying a too small of an output inverter.
If something happens to slow down or stop the chain from spinning free,(like getting the chain & bar pinched by a colapsing wood cut) the chain saw motor pulls more current to try to handle the heavier mechanical work load. This is reflected back to the inverter as a demand for more watts output & if the inverter does not have enough extra watts (not built heavy duty enough to take it) then the inverter may fry its circuits trying to put out more juice than it was designed for.
They say that it has trip out breakers to disconnect it before it fries itself & maybe that works to save the unit & maybe it don't cut off soon enough & the inverter fries.
If you buy the next larger size, you have a chance of not ruining the inverter because it is more heavy duty.
My best advise is if you think you are going to use it a lot, by the biggest one you can afford
as it will power many more tools,lights. appliances ,radio or tv than a smaller one could.
Also, do some serious compairison shopping, you could save 50-75 dollars.

here is another internet site for dc to ac inverters. I dont know what is a good price to pay so you have to compair prices & wattages.
The higher the wattage output, the higher the price & the more heavy duty so compair units of the same wattage output to other make units of the same wattage output.
good luck, very handy item to have. If some one see it,someone steal it from you,so keep locked in trunk.
