Looking for a powerbank chip that can use a single USB-C as in and output

For future drivers I am looking for a simple chip solution that combines in and output on just one USB-C socket basically a embedded solution with one chip architecture some caps and one inductor

ADDED:
Or tear down some flashlight-powerbank or cell-powerbank that has a single port.
You can find quite a few flashlights here:

As to cells, Acebeam and Folomov have cell-powerbanks.
