I don't even know what we are looking at aside from an oscilloscope wave. What is this telling you?
That the built in inverter is a modified sine wave (which
tells you when you read the fine print). A fine thing for some applications, but not for many. It is the typical design of less-expensive inverters, any thing you'd find without specifically
looking for a true sine wave inverter and the lower electronic noise the comes with it.
It seems like some "smart" chargers for some laptops, tablets, camera, quadcopter batteries get confused by modified sine wave. The end effect may be that the "charging" light comes on but it really doesn't charge.
I ordered a
