Balhvit 5200mAh Rechargeable Hand Warmer


Balhvit 5200mAh Rechargeable Hand Warmer

I bought one of these—different brand name but physically identical—and it functions great. It charges via usb (its socket is usb-c but plugs into standard usb; it did come with its own charger). It has 3 levels of heat and does get deliciously hot!
