I am looking for any way to use iPhone4s as power source of a mini peripheral device which consumes around 6W, but I could not do that because discharge from iPhone 4 failed(no discharge occured).
Does this mean I cannot feed power from iPhone4s to other devices? If so, is that because of power limit of flowing out from the device?
I understand that is not good way with iPhone, but I have to test it.

Hello takuto193,
Welcome to Apple Support Communities!
We understand from your question that you want to use your iPhone 4s to power other devices. We can certainly help you with this!
Currently you are unable to use devices other than the iPad Pro 3rd generation or newer to charge other devices.
Charge and connect with the USB-C port on iPad Pro
We hope this is able to resolve your issue. If you have any more questions or this does not resolve your issue, please reach back out on the thread!
Cheers.
