I see 2 reasons for buying a commercial or all in one power station:
1. You lack the tools or skills or time to build your own. This is an important issue for many people. You should not be messing around with big lithium batteries unless you know for sure what you are doing.
2. Portability is important to you. One could build a portable unit but it likely would not be quite as small or convenient as a commercially buillt unit unless you are really good.
Why would portability be desired? Maybe one has 2 or more vehicles and wants to easily switch between them. If one lives in a hot place like southern Arizona you really don't want to leave a lithium battery in a hot vehicle all week while you work. I wrecked an Ecoflow unit a few years ago that way. Now I store them in the house until I'm ready to go, and keep them in the air conditioned part of the truck until I get up aways in altitude.
On the other hand a custom built unit that does not need to be portable can use less space and be cheaper than a commercial unit, along with being seviceable. It all depends on your needs and skills.
