Yup, I found my first inverter out in the garage. Tripplite 115 watts, square wave. I bought it back in the '70s for my first "camper".

It still works. It puts out 144 volts at 66 Hz with a 7 watt load.

I'm equally impressed by your large dictionary. 
We don't see too many of those anymore.

Ah!!! That explains all the misspellings in forum posts.  ::)
 
Yes, the radio and TV work, although there's nothing OTA to see anymore on the TV. The TV is a '48 RCA that was originally owned by my grandparents, the Philco radio was my Dad's during WWII.

Well, What about my phone?

Yes, it works. It depnds on your POV how old it is. I built it a year ago out of antique oak salvaged from an old dresser. The telephone parts are a mix of old a new. The magneto and an incoming call ring the bells.

And, lift the hinged note shelf and there is a Touch Tone pad for dialing.

Or, if you need more access to the house phone system, open the front...
Since it's connected to the home phone system, and our "landlines" are now cellular Home Phone Connect boxes, rather than copper, I guess that makes it a cell phone. :)

Does it have a dc motor that is spinning a 120volt generator?

That's how the inverters on the first helicopter I flew, UH-1H worked.  They had a DC motor powering a small ac generators-voltages different.
 
Ah, yes, the venerable dynamotor. Nope, it has 1 big TO-3 power transistor on each side, presumably wired in an astable multivibrator circuit, and a step-up transformer inside the case.
