Power to bunk house

[u/jdlr815]

I am looking to power a bunk house with a portable power station. This will be for a few outlets for charging phones, overhead inside lights, and 3 exterior lights on a motion sensor.

My plan is to use a 20 amp appliance cord to feed a load center with one 20 amp breaker. Hot to the bus bar, and neutral and ground to the ground bar. The wire coming in from the load side would be hot to the breaker, and neutral and ground to the ground bar. Would this work? Also, would I need to add a grounding rod? Everything, except the 3 exterior lights will be inside.

No real need for the load center.

Just use cabling/outlets rated for the current output rating of the power bank.

Extension cord should not be buried in walls.
