First, turn it, then see the weight. The Zassenhaus Digital Scale Eco Energy features a built-in dynamo. By pressing the rotary knob, movement is converted into electrical energy – a principle that has long been proven with bicycles or generators. The advantage here: this environmentally friendly scale operates without batteries and is always ready for use. Impulse purchases at the supermarket because you realize just before baking that the battery is dead are a thing of the past. The high-quality glass weighing surface accommodates food items up to five kilograms, with the weight displayed in one-gram increments. The innovative functionality and modern design of the scale are complemented by contemporary features such as a sensor-touch control panel and automatic shut-off. And if you want to do even more for your eco-balance, consider doing your next shopping trip by bicycle.
