100W Pedal Power Generator for Exercise Bikes and Crank Systems Turn human motion into usable DC power. This pedal and crank generator delivers up to 100W of electrical output with an adjustable DC range from 1 to 35V and dual USB fast charge ports. Designed for mounting on stationary exercise bikes and crank rigs, it provides a practical way to charge devices, run small DC equipment, or experiment with off grid power while you pedal. Key benefits Generate power while you exercise or crank. Convert pedal motion into electricity for immediate use or battery charging. Versatile voltage range. Adjustable DC output from 1 to 35V matches a wide range of devices and systems without needing multiple converters. Dual USB fast charge. Charge phones, tablets, and USB devices directly while generating power. Reliable output up to 100W. Enough capacity for charging mobile devices, powering LED lighting, and running many small DC loads during operation. Simple integration. Designed for easy mounting on most stationary bikes and crank assemblies to add power generation without major modifications. What it does and why you need it Provides a dependable, on demand source of DC power when grid power is unavailable or when you want to reclaim exercise energy for useful work. Helps reduce dependence on plugged in charging during outdoor training, power outages, or off grid living scenarios. Useful for education and experimentation with human powered generation and small scale renewable energy systems. Features and attributes Function: Pedal and crank driven generator that converts mechanical rotation to DC electricity. Power and performance: Up to 100W output with adjustable DC voltage from 1 to 35V. Output ports: Dual USB fast charge ports for direct device charging plus adjustable DC output for wider compatibility. Compatibility: Suited for installation on most stationary exercise bikes and crank systems that accept external generators. Design: Compact and practical form factor engineered for attachment to exercise equipment and crank rigs. Durability: Built for repeated use in training and experimental setups. Practical use scenarios 1) Home training and device charging: Install on a stationary bike to charge a phone or tablet during workouts and reduce reliance on wall power. 2) Off grid and emergency power: Use pedal power to supply USB devices or feed a 12V system while camping or during temporary power outages. 3) Education and makers projects: Integrate into classroom demonstrations or DIY builds to teach about energy conversion, voltage regulation, and human powered generation. Operation tips Match device requirements to the adjustable DC output to avoid overvoltage. Use the USB ports for straightforward charging of mobile electronics and the DC output for devices requiring specific voltages. Securely mount the unit to a stable bike or crank frame and verify mechanical alignment for efficient power transfer. This pedal power generator offers a practical and flexible way to convert human effort into DC electricity with adjustable voltage control and fast USB charging for everyday and off grid applications.
