Late-season camping? Chilly tailgate? Wrap yourself up in the Coleman OneSource Heated Blanket to stay warm when the temperatures drop. Power your heated blanket 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. One fully charged battery gives you 2 hours on high (107 degrees F), 2.5 hours on medium (103 degrees F), 4 hours on low (96 degrees F), or 3 hours on pulse setting (low to high) of warmth. Game going into overtime or firing up another batch of s'mores? Double the runtime by adding a second battery (sold separately) to the dual port dock that also charges your phone or other devices and spend even more time outside. Tuck your hands into the kangaroo pocket inside the blanket for extra warmth. Toggles and loops work to wrap the blanket around your shoulders with ease and also helps to pack up the blanket into the included stuff sack. The durable ripstop-reinforced polyester cover with DWR (Durable Water-Repellent) coating repels water from the fabric to help keep you dry in case of a light drizzle.
