    Everyone agrees that the 60,000 watt claim is likely ludicrous. It is a 24 volt inverter by the way.

    A 750 mcm cable could possibly handle the voltage for several seconds? As memory serves....that cable has almost four times the mass of a 4/0 cable.

    What kind of cable are used on electric chairs? They have to be huge.
    Copper handles Amps
    Insulation handles Voltage

    Electric chairs use voltage, the human body resistance requires more voltage, only takes 10mA to stop the heart

    and from the intertubes:
    "The first execution used a voltage of about 1,700, although it was not officially recorded. The voltage has tended to increase over time and in the modern era the voltage is usually 2,000 to 2,200 volts at seven to twelve amps."

    So get a step up transformer 1:10 hook it up to this Power Jack and finally there will be a use for it, an electric chair....... because it's doubtful it can do what they claim.

    Doubtful indeed. Yet at ~155 pounds, it is likely to be quite powerful. Copper windings are not cheap.

    Don't forget to look for the bag of sand, hear the Chinese are moving their real estate one bag at a time.

    At that price I highly doubt the windings are even made of copper.

    It was $1000 at Amazon...seems to have disappeared. Don't think I have seen windings that are not copper.

    My comment was sarcasm, but you never know.
    Maybe copper clad aluminum.
    This entire thread was meant to be on a sarcastic note, at least from my angle.

    There is a "bag of sand" ballast in orbit right now.  The payload internals changed, and weight was added to keep things balanced per the original plan.  Sand got a free flight into space.  Carefully washed and bagged so as to not outgas anything.
    And I think some clone brand of test equipment installed iron weights in their gear to more closely emulate HP gear in the 80's

    Oh yes, aluminum windings are common.  Usually discovered about 3 years in, as they start to fail at the splices.

    I still have a special ache in my back from lifting those HP Spec Ans, Sig gens, and Network Anylyzers. :)

    UPS really outdid themselves this time. Appears to have been dropped about two feet. Look at the large bolt head at the bottom of the unit. Some of the racking busted loose. Weighs 102 pounds instead of 150. The coil is wrapped.....could indeed be aluminum instead of copper for weight and dollar savings.

    Seemed decent enough until UPS got a hold of it. Electronics are often not built to be dropped. The handling was so severe that I wonder if the government got a hold of it.

    Yes....I gambled on it for a few reasons.
