A direct current powered electrical heating unit capable of distributing heat across the heating unit in a substantially uniform fashion. The heating unit includes a first pliable outer layer and a second pliable outer layer. The heating unit further includes a pliable electrical heating element disposed between the first and the second cover layers and configured to convert electrical energy to heat energy and to distribute the heat energy. The pliable electrical heating element includes a heat generating element for converting electrical current to heat energy and a heat spreading element comprising graphite thermally coupled to the heat generating element. The heating unit further includes a thermal insulation layer positioned above the pliable electrical heating element and between the first and the second cover layers. A receiving power connector is electrically connected to the heat generating element. The receiving power connector configured to connect to a direct current power source.
