There are quite a few samsung pens, which can be but don't need to be charged.
That is, the writing works without charging but "air gestures" etc. additionally work via bluetooth or something and do need additional charging.
That said, due to the fact that it does have an eraser, I would still guess that it is EMR but probably with a softer tip (e.g., the galaxy folds had special pens; other emr pens are "compatible", but might damage the crease, so they are not officially compatible).
