P3 P8420 Rechargable Hand Warmer

howdy folks so I apologize for the kind of get onus of this setup I'm traveling for the holidays so I'm with family right now and this wrought iron table that's under this is the only thing I could clip my camera onto so I just had to put a placemat on it so that I could well so the screws wouldn't fall fall through it because there's gonna inevitably be a tear down of this device and wondering if anyone can guess you guess what this is it's all aluminum it's got a button two LEDs a USB charging port on it I'm covering up the text on the bottom so the Chua don't immediately know what it is you made your guess yet it's from China it's kind of dangerous it's a hand warmer I bought this about a year ago and the idea behind this is you charge it over USB it's got a lithium-ion cell in it and you push the button and it basically warms up and then you throw this in your pocket of your coat or
