Get an ammeter and a socket. Put the ammeter "in row" (NOT parallell! :) with your power circuit and connect it to the socket. Now you can measure the amperage flowing through the line. (Before start a process that consumes 100%CPU and do something graphic intensive work, e.g. a GL-game, start your sound etc. The power consumtion should be as high as possible). Becase "P = U * I" you can now calculate the electrical power by multiplicating the amperage and the voltage. But be warned. If you put on your computer, the momentary power-consumtion could be much higher than the value you have calculated. This method is only good for pre-calculating your bill for your electricity company. :) If you really wanna be shure that the power-supply in your car is sufficient, you should buy an inverter, that is strong enough for the worst case (like Brendon Walker has recommended). cu lukas -- ** PGP-key available on keyserver pgp.mit.edu ** Please don't sign your public mail unless your PGP-key is available for everyone!
