HF has a "700w" inverter that runs from a car battery. It is "700 watts
continuous for up to 30 minutes" and has "Auto battery cables and 30 amp
fuse". Is this new physics? Old physics held that 12v at 30a was 360w
and you couldn't have more watts out than watts in. This is even worse
than "Sears horsepower".

My guess is that the 700W continuous is inflated. Perhaps you should
play it safe and get this model

400W, and a 40A fuse...
