Featuring durable POM gears for smooth operation, easy-clip leads, and a clear plastic housing, this compact and portable generator is ideal for educational STEM experiments requiring reliable, battery-free power. ## Description The Deluxe Hand Crank DC Generator 15V with High/Low Output switch features easy to use connection clips, and durable clear plastic body. The gears are made of a high-performance POM plastic which features high strength, hardness, low friction and excellent stability. SpecificationMax Voltage: 15V(no-load)Max Current : 0.2A (low output, short). 1.5A(high output, short) The dimensions are 4.5-inch x 6-inch x 1.5-inch body (H x W x D). 36-inch-long leads with clips. Perfect for use with any experiment requiring up to 15 volts DC current. Low and High output switch can be used to limit power to prevent breakage of LED or light bulbs. Review: This little hand generator is perfect to demonstrate the production of electrical power and the effort required. It is very robust--not toy-like--particularly given the price. Be certain to check the setting of the "low/hi" output switch before thinking it defective. Mine came set on "low" and a it took me a touch of study to figure out the problem. A multimeter verified the claimed output voltage; actual current (amperage) is quite low. I did not measure but I suspect less than 1/2 ampere as while it can reasonably light an incandescent lamp of the sort used in automotive gauges, it can barely get a glow out of one intended for use as an overhead dome light. Low current output is intended for operating electronics experiments that require very little power. Review: Arrived non-functional; cheap construction and not built to last for use with students. ## Features - Hand cranked DC generator can be used for any experiments up to 15 volts DC. - Features a Low and High Output switch which can be used to limit power to prevent breakage of LED or light bulbs. - High Strength POM Gears for smoothness and reliability. - DC power output that can be used as a substitute for batteries. - Easy to use connection clips, Clear plastic housing and 36" long leads. 12 years and up. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0779NRLSH | | ASIN | B0779NRLSH | | Additional Features | Portable | | Brand Name | Genius Factory | | Color | Transparent | | Customer Reviews | 3.6 3.6 out of 5 stars (58) | | Customer reviews | 3.6 3.6 out of 5 stars (58) | | Date First Available | 12 December 2017 | | Engine Type | Hand Crank | | Frequency | 50 Hz | | Fuel Type | Manual | | Ignition System Type | Electronic | | Included Components | Power cord | | Is Discontinued By Manufacturer | No | | Is Electric | No | | Item Weight | 204 g | | Item model number | 787421856781 | | Manufacturer | Genius Factory | | Manufacturer | Genius Factory | | Model Number | 787421856781 | | Output Wattage | 22.5 Watts | | Power Source | Hand Powered | | Product Dimensions | 11.43 x 15.24 x 3.81 cm; 204.12 g | | Recommended Uses For Product | Education (STEM Experiments) | | UPC | 787421856781 | | Voltage | 15 Volts | | Wattage | 22.5 watts | ## Product Details - **Brand:** Genius Factory - **Fuel type:** Manual - **Power source:** Hand Powered - **Recommended uses for product:** Education (STEM Experiments) - **Wattage:** 22.5 watts ## Images ![Genius Factory Deluxe Hand Crank DC Generator 15V with High Low Output Switch for STEM - Image 1](https://m.media-amazon.com/images/I/71LxDphqinL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by M***S on 10 November 2024* This little hand generator is perfect to demonstrate the production of electrical power and the effort required.
