Hi everyone. I’m working on a project that harvests heat energy using Peltier plates (TEC 12715) and gives me voltage of approximately 2V.
I boost that voltage to using 5V Fixed output Boost module which has a usb charger integrated in it.
I plan on using that to charge my power bank.
When the circuit is open i.e. no power bank is connected, the Peltier works perfectly generating a voltage of 2V and my booster works too and generates 5V output.
BUT as soon as i connect my load (power bank), voltage generated by the Peltier (input to the booster) DROPS to 0.5V.
Please help me resolve the issue and do let me know if you need any other specifications
Thank you in advance
