คุณลักษณะ

• 6th Grade Use of Electricity: A hand-cranked generator specialized in elementary school power generation and storage experiments.
• If you turn the handle, it generates a DC voltage of about 3V, and you can see that it produces electricity by itself.
• The power generation voltage is about 3V, making it difficult to damage bean bulbs, LEDs, and electronic music boxes (electronic melodies) used in elementary school science experiments.
• You can also do experiments using dry batteries, such as lighting bean bulbs and LEDs and heating electric heat rays.
• Uses universal design cable for easy polarity switching.
• Regardless of the dominant hand, it can generate electricity in a direction that is easy for children to turn.
• The cable is a separate type that can be plugged in and out, making it convenient for power storage experiments.
• An optional adapter makes experimenting even easier.
• If the gear is worn, it can be easily replaced.
