  • Kit comes with everything you need

Build wind-powered generators to energize your electric vehicles and charge your rechargeable batteries! The wind spins the turbine, which turns an electric generator, which in turn charges your rechargeable AA batteries (not included). You can then use those wind-charged batteries to power the model vehicles you build. The six models include a glider, sail car, jet car, tractor, racecar, and tricycle.
This kit includes two styles of wind turbine blades and a gearbox with three different gear ratios for experimenting. You can adjust the angle and number of wind turbine blades to make best use of wind, to make the LED light up brightly, and to charge the rechargeable battery as fast as possible. Explore this amazing, free source of renewable energy and store the electricity you generate for use in practical applications!
This kit includes a 40-page color instruction book with illustrated step-by-step instructions for assembling two windmills and six model vehicles, and conducting various experiments. The 133 building pieces included in this set are compatible with those in all Thames & Kosmos Construction Series kits, Physics Series kits, Wind Power, and Hydropower kits.

Engine is Easy-to-Operate, Durable, and Efficient
The TG72K12 features a powerful, 14-horsepower, 420-cc, four-stroke, gas-powered OHV engine that is capable of producing 7,250 continuous watts and 8,250 maximum watts. Its easy-pull recoil and electric-start make for reliable startups every time.

The engine isn’t just powerful, it’s also quiet. Thanks to its oversized muffler, the TG72K12 portable generator produces sound at just 70 decibels during operation.

And with a 6.42-gallon fuel tank and efficient power delivery, the engine is capable of running a 50-percent load for up to 10-1/2 hours or a 100-percent load for 6 hours and 36 minutes.

The engine also features auto throttle control technology, which automatically speeds up the engine when power is needed. This helps increase the longevity of the engine and also increases fuel efficiency.

Alternator Technology Safely Delivers Electricity to Your Appliances
One of the most innovative features of the TG72K12 is its ETQ Clean Sine Alternator Technology that ensures low total harmonic distortion (THD). THD is a measure of the quality of the electricity produced by a generator, and THD above six percent can damage electronics and other components over time. With THD of less than five percent, the TG72K12 ensures high-quality, safe delivery of electricity from the generator to your electrical components.

With low THD, this generator is computer-friendly, meaning it’s completely safe to use with laptops, printers, desktop computers, and more. The TG72K12 will give you peace of mind knowing that your computer hardware is completely safe from power surges and bad-quality electricity.

Up to 8,250 Watts Power Most of Your Household Items
The TG72K12 produces up to 8,250 watts of power to run most of your electrically powered household items. You can use the 120-volt, 20-amp GFCI-protected outlets to simultaneously power lamps, TVs, computers, fans, or other low-wattage appliances. Or you can power 240-volt appliances, such as your water heater, using the convenient 240-volt twist-lock outlet. Additionally, there’s an included 120-volt, 30-amp RV connection for added versatility.

Heavy-Duty Steel Construction That’s Built for Portability
Everything–from the engine’s heavy-duty cast-iron sleeves to the durable one-inch rolled steel tubing surround–is built to last. And with semi-pneumatic foam wheels and a fold-down handle, the generator is easy to move and store. The generator weights 207 pounds and measures just 32.87 x 22.24 x 23.82 inches (LxWxH).

Outlets Feature Circuit-Breaker Protection
The generator offers several ways to connect your appliances or electrical equipment. There are two 120-volt outlets available for most of your everyday, low-wattage appliances, such as fans, TVs, computers, microwaves, and toasters. There’s also a convenient, 240-volt twist-lock outlet for running single, higher-wattage appliances and electrical equipment, such as water heaters or central air conditioners. Finally, there’s a 120-volt, 30-amp RV connection for even more usage options.

All of the outlets on the TG72K12 Portable Generator are circuit-breaker protected to eliminate the risk of power-surge damage, which can potentially ruin your appliances and electrical equipment.

The ETQ TG72K12 Portable Generator is backed by a one-year manufacturer’s warranty.

The following battery types are compatible with this generator: Champion 94b1, JBS 12N9-4B-1, Motocross M2290B, Napa 740-1869, and Powersonic CB9-B.

A clean and quiet alternative to a generator, the XPower Powerpack integrates a 60 Amp/hour AGM battery with a 1500-watt inverter and produces a 3000-watt surge. This system is built to run a range of appliances such as a standard size refrigerator and microwave oven, and office equipment such as a computer, monitor, and fax machine.

The XPower Powerpack 1500 is designed for ultimate portability. See the product specifications. View the generator in greater detail.

A convenient design feature allows for easy set-up of the cart. View larger.

The XPower Powerpack 1500 consists of a battery pack that stores electrical energy, state-of-the-art electronics that convert 12 volts from the battery pack to household power, an AC power panel that contains two standard outlets, and a DC power panel that is used to run 12 volt products. These components are packaged into a rugged “cart” with a removable waist handle that allows XPower Powerpack 1500 to be wheeled from room-to-room or outdoors over rough terrain.

An excellent alternative to a generator, the XPower Powerpack produces no noise or fumes and has no moving parts. With the accessories provided, you can easily recharge the XPower Powerpack using standard utility power from your wall outlet, your vehicle, or from a solar panel.

The XPower Powerpack can be used to produce power for numerous applications.

This belt drive pedal power bicycle generator dynamo kit is a great way to make alternative energy, emergency power, and do fun educational learning projects. Satisfaction guaranteed! We’ve been making DIY bike generator kits for 3 years and have not had one returned yet.

With this kit you will be able to charge a battery powerpack, a light, or a fun interactive floating ball display where a ping pong ball floats in the air as shown in this YouTube video http://www.youtube.com/watch?v=pcMC2oeRW5k

This kit can be assembled in 20 minutes. See video instructions at: http://www.youtube.com/watch?v=X0r9T7RwdPs

BELT vs ROLLER: You may be asking yourself which type of pedal power generator to get. A belt drive bike generator or a roller style. The roller style generator is quick to setup, but is 10% to 20% less efficient than the belt drive system when you go into higher wattage ranges. Also the roller type bike generator can be up to 2x more noisy than the belt type if your bike has mountain bike tires on it.

In the most basic of terms, a bicycle generator creates a potential energy when you move the pedals on your bicycle. The potential energy is measured in terms of “Volts”. The faster you pedal on your bicycle, the higher the Voltage reading from your generator. If you want to see a video demonstration of how this works the go to http://www.youtube.com/watch?v=mCI_Ke1tA4o
When you have nothing hooked up to your pedal power bicycle generator dynamo, you will be able to pedal with no effort at all. But as soon as you connect an electrical device to the generator output like a light bulb, or a lead acid rechargeable batter powerpack, then you will suddenly feel resistance to your pedaling efforts.
