I notice my Vector 1090A says it wants 120AC and 335 input watts. It also
has some sort of compensation for lower voltage and will still work.

I now use this with a generator or shore power. Can I also put my cheapo
400 watt inverter on the truck's battery and plug in the Vector to charge
my trailer batteries? (truck engine running). (I don't know the sustained
wattage of the inverter but maybe at least 335??)

I am assuming the Vector would do its usual, and be better than using the
other two ways to charge from the truck: booster cables battery to battery
or using the towing cable.

You'll have to try it to see if your 400 watt inverter really will
handle the load. But yes, you can indeed plug the Vector to an
inverter.

I did that very thing recently when I found the battery in my 68 Fury
dead. It was sitting right beside my GMC MD truck that has a 1500
watt inverter permanently mounted. It was easier to hook up the
Vector and a short extension cord than to muck around with anything
else. It worked just fine.

The Vector doesn't care what waveform it receives. In fact, it'll run
on DC if the voltage is anywhere from about 140 to 200 volts. I'm not
suggesting anyone try this but..... I have tested mine after looking
the PCB over.

Little known fact outside the electric vehicle world: Most switchmode
power supplies, particularly those that handle 120 and 240 without a
switch or jumper change, work just fine on DC. Many folks with EVs
with pack voltages between about 140 and 300 volts DC are using
switchmode power supplies to provide the vehicle's 12vdc for
accessories.
