Extend the comfort range of your sleeping bag with active heating. Ignik's Heated Sleeping Bag Liner is an industry first, adding safe, controllable, and sustainable heat to any setup. Add to any sleeping bag (or on its own), with 40W of power and a max temp of 140-degrees F, easily adds 20-degrees to your bag's comfort range.
Two Heat Modes: 12V Instant Heat Mode & 5V-USB Efficiency Mode
Instant Heat Mode - Connect directly to a 12V power supply for immediate heat in the 2 RCS HeatZones. Heats up within 2 minutes up to 140-deg-F. Perfect for a boost of heat and extreme conditions. Uses a standard 5.5x2.1mm barrel connector (12V-3.5A power), or optional Vehicle Adapter.
Efficiency Mode - Use the 5V-USB Adapter for power conservation and maximum compatibility. HeatZones gradually warm up to 80-deg-F. Does not feel hot to the touch, but great for adding a consistent extra "layer" of warmth.
FOR USE WITH 5V AND 12V RECHARGEABLE BATTERIES & POWER SUPPLIES ONLY * Not designed for use with 100-240V AC wall adapters *
