I’d like to build a shed for my workshop, but at this time, I don’t want to go through the hassle and expense of wiring it back to my house through an underground line and such (I have a concrete pad and lots of rocks in the way).
I think the best solution would be something like a generator transfer switch in a breaker box in the shed. Then I can run a 40amp 240v extension cable from a home outlet (e.g. a to-be-installed car charger nearby) to the shed breaker box when in use.
I would then be able to power my table saw (15 amp) and dust collector (11 amp) and lights, as well as other power tools as needed. The table saw and DC would be my biggest concurrent power draws at any one time.
Thoughts and other ideas?

It's hard to see the purpose of the transfer switch, here. My first choice would be to run an overhead line and wire it in permanently. Second choice would be to tie your 40-amp cord (must be 4-wire, i.e. two hot legs, a neutral, and an isolated ground) directly into a grounded subpanel in the shed (using a proper strain-relief connector), and just coil it up in the shed when not in use.
