Post wants to talk about money spent and smart ways to prepare... and then goes and links the portable battery system used and it is a 4kwh battery+inverter+solar charger combo with a few 200W solar panels that costs... get this..
$4399.
These stupid 'home battery' units are just stupidly, stupidly marked up for what they do.
You can buy a ~5.2 kwh 48v battery for <$1000 these days, a hybrid solar charger inverter capable of a 6kw AC single phase output (same as the linked battery system) for ~$500, and a a load of used solar panels off any number of sites for next to nothing.
People are getting fleeced by these cutely packaged battery inverter charger boxes with fancy displays and USB-C chargers, all being pushed by youtubers. If you are even mildly technically minded, you can build a more capable system for 30% the cost of these things. They are relying on people just not knowing how much LiFePO4 storage batteries and hybrid solar inverters have come down in price and how easy they are to setup.

A few years ago, I purchased a "solar backpack" because I thought the idea was really rad, and I live in Phoenix, so the thought of trekking through the urban jungle with a solar panel on my back and perpetual, unlimited sun power to my laptop and two phones, that was irresistible!
So the reality was like this: really awesome power bank included with decent backpack. The power bank has plenty of connectors and adapters to plug into virtually anything. Power bank is juicy enough to power a laptop for a couple of hours, or a smartphone for all day long. Rugged construction there.
The backpack is kind of unwieldy but has some nice pockets and it's totally electronics-aware. You don't want to stash a drink or food anywhere in this thing. There are plenty of grommets for threading the cables you'll need.
The solar panel is like the worst feature of this "solar backpack". Of course, imagine the low surface area you'll get on a backpack. Now imagine how long it takes to charge a quite beefy power bank with that. It took me 3 weeks of all day long, in the clear winter sunlight, with a zero load, to go from zero to about 90%! Three weeks!
So clearly this solar power source is inadequate to keep a device going without discharging completely by dawn. But I certainly do appreciate the power bank, and I do keep this around for emergencies, and I basically just plug it into the wall until it's full, then I stash it away and I don't worry about it for several months.
The cost was also not terrible. I think the entire backpack set cost $300 or less. Not bad for a good durable backpack plus power bank, really; nevermind the solar component.

A few years ago, I had a three-day power outage. Unfortunately, at the time I worked for an e-commerce company, and Black Friday was in two weeks - not the time for me to be off work. (Mind you, this was 2021, and temporarily returning to the office was questionable at best at that time).
Most of my neighbors seemed to have up and left. The immediate neighborhood was quiet. I ventured out and saw what had happened: a large tree had come down, taking the power lines and the road with it. So I assumed the recovery process would be something like:
1. Remove the tree - one company on one schedule
2. Re-pave the road - another company on another schedule
3. Put the telephone pole back up - the phone company (the poles are owned by Verizon in my area)
4. Restore electrical cables - the power company
And I realized that this would not be a quick process.
I threw a 100-foot extension cord out my second floor window, and hooked it up to the 400-watt inverter in my car. (Yes, I know this is terrible for my engine. The silver lining was that somehow the folks at BMW made an engine that got up to operating temperature while idling.) The other end got plugged into the three monitors and laptop on my desk. I hotspotted my phone, and... just kept going at Black Friday readiness.
At one point, I got an interesting sideways glance from the CEO on a Zoom call, as if to say - "Why are you wearing a jacket and fingerless gloves indoors? Do we pay you enough?" I'm just glad the smell of not showering wasn't transmissible through Zoom.
Although I lost most of the contents of my fridge, and I ended up eating a lot of peanut-butter-and-jelly and protein bars, I did find some ways to keep it interesting during the day. I put my moka pot on the charcoal grill for coffee in the morning, and at one point I made a grilled-ish cheese on top of the engine block.
I used a handheld flashlight and an LED lantern for light after the sun went down. And I did treat myself to dinner with friends all three nights, charging up two UPSes at their homes while we went out, so that I could in turn run some other appliances without running the car. I seem to recall at one point watching the 10:00 news on TV thanks to those UPSes.
I would not have wanted this experience with a family like this person did, for sure, but I actually found it somewhat fun and interesting.

>>> “Shortly after the 2024 presidential election - many people from all backgrounds were in a state of “what do we do when this all hits the fan?” As a black man in America fathering black children, you have to do everything within your power to be prepared for all possible scenarios.”
Have we gone so far in the US with fear mongering that it comes to this? Why would a black man fear for his life when a former president runs for a second term and ends up getting 20% black male vote overall (up from the 13% in 2016) , and 47% of Latino men , greater than any republican before him?

I’d be curious to hear what his wife’s daily blogs would look like - especially as he’s talking about ‘dad-mode, protector, provider’ - what roles did she feel compelled to occupy? If he felt like he had to step up to shield her from stress, what did she feel in turn for his sake?
(Honestly it’d be interesting to hear from the kids too)

> Whatever you think you need to have saved, know you probably need more. I quickly blew through my rainy-day funds.
Huh!? Forget canned food and go-bags. If you only have a few days worth of savings that is an emergency. I hope I’m misunderstanding what you mean by “rainy day funds”
