Features PORTABLE AND LIGHTWEIGHT: The hand crank generator is designed to be extremely portable, weighing just a few pounds. Its compact size and lightweight construction make it easy to carry and store, ideal for outdoor activities. CLEAR VISIBILITY: The hand crank generator has a transparent plastic housing that allows the motor, gears and wiring to be clearly seen, making it suitable for demonstrating the conversion from mechanical to electrical energy. SILENT WORKING: Unlike noisy gas-powered generators, the hand crank generator operates silently. This makes it ideal for use in noise-sensitive environments, such as camping sites, hospitals, or schools, where quietness is crucial. EASY-TO-USE: With a simple hand-crank mechanism, this hand crank generator requires no complex setup or technical knowledge to operate. Users can quickly start generating power by simply cranking the handle, providing immediate access to electricity in any situation. STURDY AND ROBUST: Constructed from quality materials, the hand crank generator is built to last. Its robust design ensures that it can withstand the rigors of regular use and harsh environments. Features: Amazing handheld electricity generator! Create power without batteries! Great for classroom physics teaching demonstrations. Simply turn the handle, the electricity generated makes the bulb bright. The faster you turn the handle, the more power you generate. Made with a clear plastic casing, students can clearly see the motor, gears and wiring. This grip style handle generator allows connection to electrical circuits. Screw out the miniature light bulb, can be used with almost any experiment requiring up to 6.3 volts DC. This science kit is suitable for demonstrating the energy transformed from mechanical to electrical.
