2 heating pads with 4 adjustable heat settings, one at the core and one at the footbox, help evenly distribute heat; each powered by a 4800 mAh lithium-ion battery (included) that keeps the heat going for 2 hours on high (107°F), 2.5 hours on medium (103°F), 4 hours on low (96°F), or 3 hours on pulse setting (low to high)
