Unboxing Cheap Chinese inverter from AliExpress

I purchased what I thought was a 1600-Watt pure sign wave inverter to see how it would look and run. I found in this unboxing that it was not a 1600-Watt inverter, but an 800-watt inverter. It claims to be pure sign wave, but this will be tested and verified in subsequent videos. This was not what was advertised.
I planned on using this cheap Chinese inverter in a stand-alone solar project to charge some battery-operated tools. I did not plan on using this inverter as a part of my solar power system that runs the homestead when the power goes out. But it might be usable as a part of an overall strategy in a long-term grid-down situation.
