Review on Rechargeable Hand Warmer 8000MAh Power Bank By BRIGENIUS - Double-Sided Heating For Winter, Outdoor Activities, Raynaud'S, And Christmas Gift Ideas by Thomas Unruh

Wow. I was pleasantly surprised by how warm it was and stayed. I am a teacher in Connecticut. It has been in the low 30’s lately and I have been freezing at arrival and dismissal. This is truly amazing, I am able to keep it in my pocket and hold it- then switch to the other pocket. Love this! Charge has been lasting a few hours. Only issue is that I need another one!
