Plugging shore power into inverter
I'm about to buy an inverter for my travel trailer. It has no 12 volt outlets, so I think ac is the easiest way to go. Can I plug the shore power plug (with an adapter) directly into the inverter an...

By the time you allow for inverter losses (they are at best about a 12% loss), dividing the watts by ten gives you the draw at 12 volts. So the Microwave may draw 90 amps, not 9.
If the microwave says 900 cooking power, it may draw as much as 1300 watts. Now the draw may be 130 amps.
To size an inverter take the largest load and multiply by 125%.

At 900 watts, the microwave will draw 7.5 amps if used for 6 minutes(by my math). That's probably more than I will use it in a day. But yeah, it will require a larger inverter.
