    Can i wire an inverter like this

    i have a 400/800 watt chicago electric dc-ac power inverter i bought used on ebay. i cant find any specs on it or wiring schematics. im gonna put it in my car to run my laptop.
    i have a 400 watt amp running my subs. ive got a 4 ga. wire ran to it which is really overkill. so im wondering if i can get away with wiring the amp and inverter together on that wire...split it with a distribution block...then have 8ga wire going to each one.
    as long as it doesnt pull too much current through the 4ga wire it would work i think. the reason i want to is i dont want to run another wire from the battery. and im just gonna run my laptop on it, not huge loads.

    has anyone ever tried this?

    The only way to be sure is to calculate the power draw of both the amp and the inverter. Max load of both would be 400 + 400 watts = 800 watts.

    Watts = Volts * Amps, so 800 = 12 * A. Amps = 66 amps, or 33 amps on each 4 gauge wire. The 12 volt.com says you can get away with a wire run of up to 12 feet at that amperage for 4 gauge.

    The actual max load is probably less since when the car is runnng it outputs closer to 14 volts.

    Do yourself a favor and power your laptop with an auto power adapter (or DC power adapter - same thing).
    Battery charging systems and laptops don't play nice together in many cases.
    Have you looked in the FAQ yet?
    How about the Wiki?

    Good point. No real need for the inverter when you can buy a power adaptor for about the same price.
