CookTeK ThermaCube Small Bag Only -- 1 each.The CookTek ThermaCube thermal delivery bags are designed for use with CookTeks ThermaCube induction bag chargers. A ThermaCube specific pellet tray assembly must be ordered for each bag. A typical store installation would comprise of up to 10 complete insulated delivery bags to one charger. Beyond that number, a second charger is usually employed. In use, a complete bag (with pellet cage inside) is placed on the tray of the charger. A red light comes on automatically to indicate that heating is in progress. When the red light turns to green, the bag is ready to use. Simple as that! From completely cold, it takes up to 3 1/2 minutes to heat a bag. Once there is some residual heat in the bag, re-charge times are much faster - typically about a minute. Replacement pellets tray assemblies are available separately as spares. Features & Benefits For use with ThermaCube induction bag chargers only. No cords on the bags.
