 +One way to **predict if you will reliably set up the portables**:  how full is your vehicle's gas tank and your phone battery right now?  If you are a "never let it get low" type you will likely set out portables consistently.  If you are a "always running on [E]mpty" type you are less likely to set out the portables. This is a not a moral judgement, but rather a way to help assess whether or not portables would be a good source of power for your use case.
