The generator produces direct current electricity, generating a maximum direct current voltage of about 12V. Since it outputs direct current, it can be used in various ways as a substitute for batteries. It is useful for lighting small bulbs, operating motors, and for experiential learning about electricity. The polarity changes with the direction of the handle's rotation. Turning the handle to the right makes the red of the alligator clip positive (+) and the black negative (−). Turning it the other way reverses the polarity. It can also light a 100V bulb. By connecting multiple hand-cranked generators in series, the voltage increases. For example, connecting five in series can yield over 50V, allowing a 100V bulb to be lit. The grip and handle are designed to be easy for children's hands to hold. The handle can be folded for compact storage. Size: 115×41×112mm, Weight: 145g. Cord: 1m, with large red and black alligator clips.

Calm black design Due to the different operating voltage from other standalone solar modules, only the SolarAmp (SA-MPPT-15L) charge controller is compatible. By combining it with SolarAmp, systems ranging from 70W to 160W for 12V systems and 70W to 400W for 24V systems can be easily assembled.

The solar cell modules from K.I.S. that meet these quality standards not only ensure safety but also demonstrate excellent performance in stability, durability, and weather resistance over the long term. With the adoption of crystalline silicon for high efficiency, they have a proven track record in public and industrial applications such as traffic signs, emergency phones, radio stations, irrigation systems, outdoor lighting, and outdoor clocks. They come in a wide variety of options to suit different applications, from small systems to independent distributed and grid-connected systems. The modules feature reinforced glass and corrosion-resistant aluminum frames. The marine models (BT432S-MRN, BT832-MRN) use a highly weather-resistant transparent PVF (polyvinyl fluoride) film for the front cover and a rubber frame to prevent damage to yachts and boats. They are not only suitable for marine applications but are also gentle on car bodies and people, offering a thin, lightweight, and easy-to-handle panel.

Mysterious beads that change from white to colorful colors under ultraviolet light. The whitish beads quickly transform into vibrant colors when exposed to sunlight, and they return to their original state when placed in a dark area. They can be used as beads for accessories such as bracelets, necklaces, and mobile phone straps. They also serve as a UV checker for sunburn and UV protection.
