    The car has everything off (radio, etc), only the engine is on. It's a Ford Fiesta 2002.
    Input Voltage of the inverter: 10-15 V
    Nominal power: 300 W
    Maximun power: 350 W

    May the power is from the power supply?

    Thanks for your quick answers

    yes that could be. your battery could be about dead. also depending on where you are gettin power from. is it connected directly to the battery? or some line you cut into?

    well the alternator is what recharges your battery. and if that is not fit then it will drain your battery and eventually lead to your engine being dead on the side of the road because battery is dead and can not get enough juice from alternator to keep running. Like I have found out with my past two vehicles(with no computer) :OP . No its no big problem just something to keep in mind. You can always take it in and test it if it is a major consern to you. I dont know what the problem with the inverter is. I get the same problem when I take my laptop/inveter with me in my mothers car, but it does not do it in mine. Also I have just gotten a new alternator. Im sorry im lost there... um I just bought these145 watt psu when i get them ill prob want to sell the other two. I dont know if that
    would be a reason why, just another to keep in mind. Sorry bro im at a loss right now. Any one else???
