Are you asking to buy ONE longer cord and cut it up into several for the several items?
If so, then for an inexpensive cord, a Shunyata Venom 3.
The wires are not complicated inside of it.
I would NOT recommend a Pangea 9 gauge at all, as it is thick, complicated, and the other diameter would preclude nearly any connectors available.
Though the 14SE could be done, though the conductors are complicated multi wires in the sheath.
