    Is there a spec sheet on what the maximum wattage inverter I could run off of my Gen 4 prius? So far I've run my TSW 1K inverter with an angle grinder, jig saw, belt sander, and a 100 watt per channel stereo amplifier.

    The power tools were all old Craftsman brand that maxed out around 450 Watts, even under load. Thank you.

    Does a Gen 4 Prius have V2L from the traction battery? Or are you using the 12v lead acid battery to power the inverter?

    .....just a swag but they probably fuse the DC-DC converter at 100a.
    I wouldn't go much above a 1000w inverter, which has been done many times here in the forum.

    MAYBE 1500w if you carry a spare fuse..... :D

    Good Luck!
