Thank you for viewing. This is a Panasonic nanoe generator. I purchased it last year at an auto parts store when I bought a car. However, it didn't fit well with the drink holder, and after driving for a bit, I became concerned and ended up removing it and storing it without using it. It's not completely unused, but I haven't used it much. When I placed it in the drink holder, there might be some scratches, so please refrain from purchasing if you are sensitive to such things.
