Connect components reliably?
Hello everyone, does anyone have a solution for my problem:
I'm currently working on my final project for school. I want to generate electricity using my own muscle power and ultimately be able to reliably charge my cell phone.
I want to connect four dynamos in series, each producing 6V and 3W, so that I can then produce a maximum of 24V and 3W. (Dynamos produce alternating current and have no plus or minus pole), but I need between 12-24V for the transmitter (simplest choice, as we already have one at home, otherwise just a cigarette lighter plug with a USB port). That's true, but I can't charge my cell phone with 3W. Next, after the last dynamo the cable leads to a bridge rectifier which converts the alternating current AC into direct current DC. From the rectifier the cables go to a cigarette lighter, where the two wires are connected to the two poles. Next, a transmitter goes into the cigarette lighter, and then I can charge my cell phone with a USB cable.
How do I connect all the components correctly so that I can then charge my phone safely and reliably using my own muscle power? Is there a good solution to generate more power (W)?

Thank you for the help😄

The dynamos would have to rotate in the same phase, otherwise you will never get the desired voltage. Example with two: one makes straight plus 6Volt, the other minus 6V gives in total zero. For phase equality, you must provide mechanical care.
What do you mean in phase? What is the difference to a normal bike dynamo?
"… do the 3W" in the next sentence "I can't charge with 3W"
That's contradictory.
What do you mean with a transmitter?
In short, I don't produce enough power to charge a mobile phone, as each cell phone needs at least 5W to be charged, but I only produce 3W. The transmitter is a device that is plugged into the cigarette lighter and allows to connect a USB cable to charge your phone.
I thought so. But if you only produce 3W, nowhere will come out 5W, on the contrary – with each device in between you have losses, even in the diodes of your rectifier.
