Its ball bearing shaft and ventilation holes ensure reliable, heat-managed operation, making it ideal for sustainable energy generation on the go. ## Description This model PPG-B300 generator dynamo is a belt / pulley driven unit which generates a DC Voltage that is directly proportional to the revolutions per minute rate that you spin the shaft at. For instance the following table shows you the generator output based on revolutions per minute: Generator rotational speed DC Voltage Output 500 RPM 3.6V DC Output 750 RPM 4.9V DC Output 1000 RPM 6.0V DC Output 1500 RPM 9.5V DC Output 2000 RPM 12.2 DC Output 2500 RPM 14.5 DC Output 3000 RPM 17.0 DC Output This generator can charge a 12V battery through a blocking diode and a fuse. Or it can charge a battery through a charge controller which has a built in fuse and blocking diode. The PPG-B300 is easiest to install by screwing it down to a piece of plywood and then setting a bike stand on the same piece of plywood. See product photo. You will have to remove the tire from the rear wheel of a bicycle. After the generator is secured atop the piece of plywood then you can use an adjustable powertwist size 3L V-belt to connect the generator to the rear wheel of the bicycle. Please contact us if you have any questions. This generator can also be used to charge a portable solar generator also known as a portable power station. The Voltage output must not exceed the maximum allowed charge Voltage of the portable solar generator / power station. If you would like help on selecting a charging solution that suits your needs please contact us with your questions and a qualified electrical engineer will assist you. This generator can also be used to setup in classrooms to teach students about S.T.E.A.M. science technology engineering art and math. It can be connected to a leaf blower in a vertical position with a beach ball floating when the person riding the bicycle generator pedals the bike. ## Features - Permanent magnet DC Generator - Output Voltage: 0 to 40 Volts DC V-belt pulley size 3L - Nominal Current 15 Amps, Peak Current 20 Amps - Great for charging 12V deep cycle lead acid batteries through charge control - Also works as DC Motor .4 Horse Power ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001WB3TZ4 | | Additional Features | DC Power Generator | | Best Sellers Rank | #688,082 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #1,521 in Outdoor Generators | | Brand | Pedal Power Generator | | Brand Name | Pedal Power Generator | | Color | Black | | Current Rating | 15 Amps | | Customer Reviews | 3.6 out of 5 stars 14 Reviews | | Engine Power Maximum | 300 Watts | | Engine Type | electric | | Fuel Type | None (or human, wind, hydro) | | Ignition System Type | magnet | | Included Components | 6mm Bolts, 2 inch pulley, 300 Watt Generator (Peak power is 300 Watts) , Typical power is 150 Watts. | | Item Dimensions L x W x H | 5"L x 6"W x 5"H | | Item Weight | 8 Pounds | | Manufacturer | Pedal Power Generator | | Manufacturer Part Number | PPG-B300 | | Material Type | Metal | | Model Name | PPG-B300 | | Model Number | 300W-DC 12V-24V | | Output Wattage | 300 Watts | | Power Source | Pedal Powered by Human Power | | Recommended Uses For Product | Camping | | Running Wattage | 300 Watts | | Starting Wattage | 300 Watts | | UPC | 837654324868 | | Voltage | 40 Volts | | Wattage | 300 watts | ## Product Details - **Brand:** Pedal Power Generator - **Fuel Type:** None (or human, wind, hydro) - **Included Components:** 6mm Bolts, 2 inch pulley, 300 Watt Generator (Peak power is 300 Watts) , Typical power is 150 Watts. - **Item Weight:** 8 Pounds - **Output Wattage:** 300 Watts - **Power Source:** air-powered - **Recommended Uses For Product:** Camping - **Special Feature:** DC Power Generator - **Voltage:** 40 Volts - **Wattage:** 300 watts ## Images ![300 Watt Permanent Magnet DC Pulley Generator 3/8" V-Belt Drive Pedal Power Pulley Dynamo with air ventilation holes PPG-PM300-P - Image 1](https://m.media-amazon.com/images/I/61n1mLKbGpL.jpg) ![300 Watt Permanent Magnet DC Pulley Generator 3/8" V-Belt Drive Pedal Power Pulley Dynamo with air ventilation holes PPG-PM300-P - Image 2](https://m.media-amazon.com/images/I/71g+SdyXzML.jpg) ![300 Watt Permanent Magnet DC Pulley Generator 3/8" V-Belt Drive Pedal Power Pulley Dynamo with air ventilation holes PPG-PM300-P - Image 3](https://m.media-amazon.com/images/I/51cHPXlNT0L.jpg) ![300 Watt Permanent Magnet DC Pulley Generator 3/8" V-Belt Drive Pedal Power Pulley Dynamo with air ventilation holes PPG-PM300-P - Image 4](https://m.media-amazon.com/images/I/61s1v+v6PRL.jpg) ![300 Watt Permanent Magnet DC Pulley Generator 3/8" V-Belt Drive Pedal Power Pulley Dynamo with air ventilation holes PPG-PM300-P - Image 5](https://m.media-amazon.com/images/I/615TQX+r2qL.jpg) ## Questions & Answers **Q: does direction of rotation matter for output?** A: If you want to rotate clockwise then connect the negative wire (black one) to the negative one of the thing you want to power. The red one should go with the positive end. You can rotate in the other direction, but then the black wire is positive and the red one is negative so you just have to keep that in mind. **Q: What are the lowest rpms that it can run to produce roughly 100watts? OR what is the curve?** A: That is good resistance, the answer is based on what the resistance is of what you are trying to power up. Are you going to power up a light? A battery? A cell phone? Keep in mind that nearly any electrical system is less efficient at lower Voltages because of losses due to resistance in the wire and in the armature of the generator. Is efficiency an issue? Making the assumption that we are going to run at 500 RPMs (revolutions per minute), then you would see approximately 3 Volts DC coming from the generator. If you want 100 Watts of power at 3 Volts then the current going through your load would need to be about 33.3 Amps The generator is not rated for that much current. So if we double that speed to 1000 Watts, you would get about 6 Volts from the generator. At this point you would need about 15 Amps of current to deliver 100 Watts to the load. 6 Volts divided by 15 Amps would be 0.4 Ohms resistance. (Volts / Amps = Resistance). Does this answer your question? Best regards and good luck with your project, Bradley Whaley ELectrical Engineer Pedal Power Generators **Q: can it be used with a bicycle in movement or only a stationary one?** A: When you attach this generator while moving it will add resistance to your pedaling so that you will have to work harder than normal. So for instance if you wanted to put a 20 Amp Hour 12V Battery onto your bike and charge the battery while you ride the bike around town. This would make it very hard to make your bike go faster than 5 miles per hour because it would place such a drag on your tire. If you installed a button on your handle bars for regenerative breaking, then you could use this button when you go down a hill or only when you want to stop the bike, that way you could harvest the kinetic energy (1/2 x Mass x Velocity) from your bike and put it into the battery. **Q: Can it be used to charge a 48v ebike battery?** A: You will have to have a inverter On a bike this gen. will make 12v or 24v. unevenly. That is not the gen. It's the pedaling on the bike. If you put a charge controller for a wind mill it will even out the highs. and the lows. Then invert to 48v ## Customer Reviews ### ⭐⭐⭐ Review *by S***E on June 12, 2014* ### ⭐⭐⭐⭐⭐ Review *by A***E on December 30, 2022* ### ⭐⭐⭐⭐ Review *by N***E on February 15, 2012* ## Frequently Bought Together - 300 Watt Bicycle Generator 3/8" Belt Drive Pedal Power Pulley Dynamo - Porch Shield Waterproof Universal Generator Cover 26 x 20 x 20 inch, for Most Generators 3000-5000 Watt, Light Tan - Scepter FR1G152 Fuel Container with Spill Proof Smart Control Spout with Bonus Spout Extender, Red Gas Can, 1 Gallon --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/10059624-300-watt-permanent-magnet-dc-pulley-generator-3-8-v](https://www.desertcart.id/products/10059624-300-watt-permanent-magnet-dc-pulley-generator-3-8-v) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-09*
