I needed some 5V power supplies to run a couple Arduino's, so I ordered some from Amazon for cheap, Chinese, of course.
These exact ones:https://www.amazon.com/gp/product/B0777HWN87/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1
Amazon Prime dutifully delivered my power supplies which put out a nice 5.2 VDC, but inside the sealed box from China was the thing I have pictured below. It's stem thing is flexible, and holds the shape you bend it into. the white thing does not seem to come out nondestructively.
I'm beyond curious what was shipped inside my power supply box, but am not stupid enough to plug it into anything I like, or own.
Does anyone in the brain trust recognize it?
