I have no idea what it is for but it had battery still left in it and a micro USB slot. Wife has not clue what it is either. Not sure if a random guest left it or my toddler picked it up.

According to alibaba it’s a “Professional DIY portable wireless battery powered smart abs ems electric body abdomen muscle stimulator”
Ahhh… the ol’ PDIYPWBPSAEMSEBAMS.
Yeah, I think that’s what it is. I also ended up finding this link from Walmart after your post with the exact same device: https://www.walmart.com/ip/Muscle-Stimulator-Abs-Arms-Hips-Back-Legs-USB-Rechargeable-Toner-Wireless-Portable-EMS-Abdominal-Toning-Belt-Men-Women-Office-Home-Gym-Fitness-Equipm/135124249
Asked the wife… she bought an abs stimulator years ago but never even used it so she didn’t remember. I guess solved. That was fast. Thanks
