How much power does an inverter use?
In our Casita travel trailer, I have one 12V outlet. I have two inexpensive inverters (Walmart) that plug into the 12V outlet: one inverter is 100W, the other 400W. My laptop needs 90W to charge. ...

The 100 and 400 are less than that continuous. The 400 will be about 320, so use that.
meanwhile the RV 12v socket might only do 8 amps so your laptop wanting 9 amps is pushing it. You want the 400 on a battery with wires and clamps (it should have come with a set) to do that job.
