After the invention of the alternator and that alternating current can be used as a power supply, the word dynamo became associated exclusively with the commutated direct current electric generator, while an AC electrical generator using either slip rings or rotor magnets would become known as an alternator.
For that reason, can a dynamo charge a phone? Mobile phones can now be recharged while riding a bike. Phone firm Nokia has released a charging kit that uses a dynamo powered by a bicycle's wheels. Any cyclist wanting to re-charge their handset using the kit will need to maintain a speed of about 4mph (6km/h), said Nokia.
Equal, what is dynamo charging?
The Sinewave Cycles Revolution is a bicycle dynamo powered USB charger. It converts electricity generated by hub and bottle dynamos to USB output. The Revolution allows users to charge USB-powered devices while riding. The Revolution is made in the USA.
Do dynamo hubs slow you down?
Given the leverage of a wheel and the flywheel effect of the rotating mass, dynamo hub drag only has a small effect on your speed. The result for most people is likely to be an extra three to six minutes riding time over 100km, all while getting a good charge to your electronics (or while running lights).

A hub dynamo is a small electrical generator built into the hub of a bicycle wheel that is usually used to power lights. ... Most modern hub dynamos are regulated to 3 watts at 6 volts, although some will drive up to 6 watts at 12 volts.
For those unfamiliar, a dynamo hub is a hub that uses a small internal generator to produce electricity as the bicycle wheel rotates. This electricity powers a light system and can charge a small electronic device with the right setup. ... You can grab your bike and go with one less thing to worry about.
Having lights permanently mounted on and powered by your bicycle means you'll always be well lit. What is a dynamo? A dynamo is an energy-generating hub built into the front wheel of a bicycle that typically powers lights. Dynamos can also power USB ports and all manner of fun things, if you're interested.
How Does Bicycle Dynamo Lighting Work? ... Using the rotation of the bicycle wheel to generate electricity, the dynamo can then produce an electric current which is then delivered to the lights. The faster you cycle, the more power generated, and so the brighter the light.
The dynamo will charge the battery as long as its voltage is higher than the battery's voltage. ... You will need to control the current going into the battery, especially since your battery has a relatively low capacity compared to the capabilities of the dynamo.
Essentially any electric DC motor with a permanent magnet can become a dynamo. Rather than applying current to the motor to cause it to spin, you can turn the shaft of the motor and generate a current.
Our hand/foot crank is a great way for anyone, young or old, to get involved in generating clean electricity. A simple rotation of the handles will generate anything from 10 to 400 watts of electrical power. Features: Rugged build with a heavy steel frame.
You can make a DIY generator, or dynamo, through some simple items you may have lying around your house. To make one, you'll need thick semi-thick cardboard, four small ceramic magnets, a hot glue gun, about 200 feet of magnetic wire, a small light bulb and a large nail.
Dynamos and Generators convert mechanical rotation into electric power. Dynamo - a device that makes direct current electric power using electromagnetism. It is also known as a generator, however the term generator normally refers to an "alternator" which creates alternating current power.
A generator, also called a dynamo in some areas, generates DC power. An alternator generates AC power, but most alternators have rectifiers directly attached to convert the AC to DC. Alternators are more efficient, so they have replaced generators for most if not all automotive applications.
