Root for your team on the sidelines or stay around the campfire even longer after the temperatures drop with the Coleman OneSource Heated Chair Pad. Place it on a bleacher seat or to a Coleman camping chair for added warmth. Power your heated chair pad using the lithium-ion rechargeable battery, an interchangeable battery that works with all Coleman OneSource products, and eliminate the need for multiple power sources by charging your devices through the USB port. The seat cushion has 4 adjustable heat settings that allow one fully charged battery to keep the heat going for 1.5 hours on high (133°F), 2 hours on medium (123°F), 3 hours on low (113°F), or 2.5 hours on pulse setting (low to high). Double the runtime by adding a second battery (not included) to the dual port dock that also charges your phone or other devices. Light drizzle at the tailgate? Sit outside comfortably, the weather-resistant fabric and nontoxic PU coating helps protect the chair pad against water and rain.
