I can't quite give a final answer for 1 & 2 because I'm still finding out the balance between what I can get vs. what I can pay. Since I move around a lot, I am looking for portable options. So no house generator + barrels of gas.

I definitely would like to power a phone for a minimum of a week. Preferably two weeks. So that's 7 charges at a minimum.

Powering a router would be nice, but if there is widespread blackout, will I have internet? I have DSL if that matters. During this last blackout, I had mobile data prior to Sally's arrival. After she(? it?) made landfall, I lost mobile data. I still don't have it a few days later. I suspect if I want to keep the router on 24/7, it may suck up more power than I have to spare.

Occasionally I may need to use my laptop (let's say 30 minutes a day). Currently I have no plans to try to get work done (which requires extended use of a computer). It's a good idea not to let employers think disaster time = more work time.

I don't plan to power a fridge. I think that will require a gas generator.

I have no chainsaw currently. So we don't have to worry about that.
