    Bump Down An Inverter's Wattage?

    OK Guys, (and gals )

    I have a 400w continuous inverter , the only thing is, is that i will be powering only a laptop with it . Is there any way for me to bump it down to something more like 100 watts or so?

    Please let me know.


    Thanks!!!

    Invertors only "use" as much as you're drawing. (plus a little overhead to make the invertor work) It -WILL- drain your battery overnight if left on, as is the nature of most car appliances. However, the 400w Continuous is simply referring to the maximum output that the invertor can sustain. that particular invertor you're using could power, oh say... a 13" television -and- dvd player?

    If it was cheap and you can't return it, I say stick with it.

    (Power equals current times voltage)

    And remember, power is a measurement of work, in this case, the work done by the current and the voltage.

    The inverter _is_ the car appliance. If the inverter is left on it will drain your battery.

    Think of power just like Horse Power of a car. If you are idling around the neighborhood at 25 MPH in your 300 HP mustang are you really using 300 HP? No your using about 20 HP. If you Floor it and get up to 7000 RPM are you using 300 HP? Yes you are maxing out the HP of your Car. The same is true for power of electronics. You don't alyways need 300 HP, but isn't nice to know it is there if you have to pass someone? If your car always used 300 HP you would get 7 miles to the gallon everywhere you go, and your engine would wear out pretty quick.
