Easy Carry Light Weight USB Heater, Electric Cloth Heater, Heating Pad, for Indoor Outdoor

The item is so-so, but as usually a Chinese good is lacking something. This time the bad thing is that the pads do not have a separate wire but are linked in a serial connection - it is one wire that is going from a pad to the next. It's not a star scheme of connection, but rather a ring. Thus, the area of covering is reduced. Otherwise, it's pretty nice, it has 3 heating modes: red color - constant heating; blue color - rapid on/off mode with the on mode twice longer than off mode; green color - rapid on/off mode with even periods of time, this is the less warm. By the way, the current is 1.6-1.8 Amps at 5V, wattage from 8 to 9 Watts. Finally, would still recommend.

Perfect for warming up exactly where it feels good even when you are in pain, of course also very good now for the cold season under a hat.
