Hello. I am planning to make rechargeable power bank using dynamos. What do you think? How can we do that?

Yeah, that’s just for fun. I am looking forward to making this as my one of my achievements​. And, this is quite a different concept because I have not seen such product in the ​market in India.

You can look into already available dynamos in the market and select a suitable power bank that matches the technical specifications

That way you will be able to build it

Shrey Fadia I was trying to build a similar kind of circuit … The motor gives out voltage ripple in the waveform if that’s managed then the circuit will be running up in no time. I tried with the 12v motor used with the bots.

Shrey Fadia check out DIY Rechargeable Batteries
Use a lipo/li-on battery with a battery management system (BMS) to charge and protect it.
If your dynamos can give ~13V, you can charge the cells through the BMS.
