I bought mine at Fry's electronics in Phoenix when I was out there. I brought it back to my apartment, hooked it up to a battery charger & started plugging in all kinds of appliances to see what it could do.
Well, it had it's limits -- it would run a blender until you got into the higher speeds, it ran my TV, & electric drill with very little load on it -- couldn't do anything useful with it.. like drill! -- could run several lights on it, etc.
The problem I had was the battery charger I was using was over 50 yrs. old , & liked to pump out some pretty HIGH DC voltage. I was sitting on the floor messing with the blender on each speed when there was a LOUD POP -- then the blender stopped abruptly!! Scared the *censored* out of me!! Then smoke started pouring out of the unit from every gap.
I took it apart & it looked like a cardboard box exploded inside & it reeked. Then I found an empty shell of a capacitor.............so I went back to Fry's, matched up a capacitor, & soldered it in........this all went down in 2001 & I still have the unit right now. Turns out, the charger was putting out 21.4 VDC -- just a tad too high....
