The heat mostly comes from the thick blanket
[[VIDEOID:d42a290dfccd3b3abff4bce7dcecbcf]] The blanket comes in a nice little folded carrying case. When unrolled it's decently thick with one side being cloth and the other side because a more plastic material. You can plug the blanket in via USB portable charger (sold separately) and choose 3 different heating options. The blanket heats slowly but eventually you feel a small amount of heat coming from it, even on the highest setting. The thickness of the blanket and the black reflective side really ensure the heat stays on you though. Just don't expect to have the same amount of heat as a blanket that plugs into a wall outlet.
