Hey Tim, The Kat's # KH30904 is a 300-watt engine block heater, and while it doesn't have a fixed "max temperature" rating in the way a thermometer does, it's designed to heat engine coolant or oil, often reaching temperatures within the engine's operating range, typically around 135-175°F.
The cable is 6 foot long.
