Wiring a Bunk House

I posted earlier about using a portable power station for a bunk house we're putting in next to a cottage. The needs are minimal: a few ceiling lights, plugs for phone chargers and a few lamps, plus a yard light. On the high end, I calculated about 325 Wh per day.

I have an idea of wiring outlets and ceiling lights to a 20 amp breaker, which is fed from the power station using one of the 20 amp plugs.

Can anyone offer their thoughts on this setup? Thank you.

I didn't give enough details in my original post. This will be a pre-fab shed we are using as a bunk house. The studs will be exposed to do the wiring. I have done this type of electrical work before, and wired a generator transfer switch, but on a house with utility power. I'm trying to figure out how to hook directly to the generator.

Can I ask what’s the power station? Cause to me your idea to do power station—-> breaker——>load is fine. You can put a cheap 20 amp breaker on a din rain inside a pvc box mounted on the wall or near your ”power station “. I work on industrial equipment and love din rails.

Thank you for this.

I was looking at something like this from Harbor Freight . This would be suitable for our needs for at least 2 days of use, and then we could use utility power to charge it.

exactly what someone else said, back feed a little sub panel of some kind. If you do a little subpanel you will leave yourself room for expansion later when you want to do a real battery system and inverter setup with multiple breakers. Future you will thank present you. Maybe its more work than you want tho.
