Anna raises the temperature! Not just because of her hot looks, but mainly because this wonderful little heater is equipped with a modern PTC ceramic heating element. Anna heats discreetly and quietly with two power levels, bringing wonderful ambient warmth. But the clever heater also stands for safety in two respects: no overheating thanks to the PTC heating element (self-regulating ceramic) and tilt protective automatic shut-off. Anna Little is perfect where a little extra heat is needed (under a desk) or in a small space.
