    When your crank your engine to start, the computer resets itself and has to restart. Kind of like when you have a power outage for a second, your home computer reboots. Some power supplies allow the computer to run the 2-3 seconds it takes to start up the vehicle.

    Part of that statement is true but I don't think you explained it fully.

    When you start your car you get a voltage drop. If you car has a proper working charging system then your voltage should not drop below 10.5V. This is a voltage level that a lot of inverters use as a cutoff point. Obviously your computer gets no power when the inverter input voltage drops that low and causes it to turn off which will make the computer turn off. So, this is where the reset on cranking term comes in.

    Just an FYI. I've used invereters for all my computer setups in my cars and have never had issues with the computer rebooting.

    Some cars actually disable all accessory power while the engine is cranking. The only thing being powered are the required items to get the vehicle running, ie. starter, ignition electrical system, etc.

    Ahh very true statement. This is why you should, if you want to, wire the inverter directly to the battery to avoid the problem.

    Hnrm...I have an Unorthodox underdrive pulley so my alternator tends to charge at lower voltage than normal, eventually resulting in my voltage dropping to around 9 when cranking.

    My understanding is that the inverters automatically shut down once they get below a certain voltage...what would happen if that was disabled (if it could be disabled at all)? Would the inverter only put out fewer volts or would it cause some other trouble?

    Does this happen with the 150w opus DC-DC unit($190.00, it think)

    Why would someone pay 190 when they can get a cheap inverter and it will do the same!

    whats the difference

    thanks

    The Opus supplies (and Sproggys for that matter) do not have this problem.
