No plug included.
These slipper do not come with a plug.  You have to find a correct usb plug, which if incorrect the plug overheats quickly and slippers burn.  Without receiving a plug, you cannot use slippers.  Also, the picture shows a white power battery and says you can use outdoors.  You do not get the battery and you absolutely cannot wear these outdoors.  The heating element zips into the front, which easily unzips and the element comes out. Also, fabric is not damp-proof.  Beware. Not as promised.  These are not as shown.
