Collection of peculiar portable devices, part 1

I had to share a gallery of weird devices with few people in short period of time, so making an easily findable (for me) place for it seemed like good excuse for a post.

Gallery is split to groups per 100 images, so be sure to check all of them, otherwise it'll only loop through first 100 instead of all 400 pictures.

I have no information about these devices, you're free to reverse image search them, and put comments with models/information about them under this post, I'll update them when I have time.
