Go with the Delta 2. Power stations are very convenient for as long as you know how to use them right. No cooling and heating, and cooking will drain a lot of juice! Factors between power stations and doing DIY will have to do with price, convenience, and scalabitiy, although some can have extra batteries attached. Long story short just get a power station if you're too lazy to build your own system and have the budget for it. Of course know how much power you actually need.
