I'm only half kidding. I'm a bit of a prepper and I have lots of powerbanks and devices that charge from USB but besides idling my truck I really had no other way to charge any of them in case of a long-term power outage which seemed a bit of an oversight on my part.
Not like this solves the issue. 30 watts (under ideal conditions) isn't much but it's a start.
In the event of an apocalypse basically nothing that you can charge is going to be of any use other than flashlights.
devices with offline knowledge. you can download wikipedia to your device.
also gaming consoles against the boredom and to maybe connect to the neighbor for fun?
Depends on tge apocolypse, but Refrigeration... HVAC.... Power tools... Could go on.
Maybe even your phone if you've downloaded books/manuals/maps needed to rebuild before hand
What is 30 watts going to do for any of those? I don't think people here know how weak a 30 W panel is.
The argument was that: "basically nothing that you can charge is going to be of any use other than flashlights" not that 30 watts is sufficient for long term.
My strimmer battery charger takes 65w. So 8 hours of 30w to charge a battery is almost 4 hours charging the strimmer battery which would probably fill it's small battery a few times over. If you are not depleting the strimmer battery multiple times a day, that is more than enough power.
You of course do need a battery to store it so many hours of solar are used in several minute short time loads.
Laughing with mp3-player.
In an apocalypse I’m not drowning out my hearing with music! Good way to get your mp3 player, battery, and solar panel stolen! Haha
Electric fire starter. Mesh nodes. Walkie talkies. Small computer with offline Wikipedia and Google maps. GPS may still be working for a while, so that would be useful to charge and use. Portable fans. MP3 player or other entertainment device. Camera. Small power tool batteries....
Yeah, in an apocalypse, a small about of electricity would be a luxury.
30W panel ain’t gonna do that.
Wrong!

Runs on a 5W panel... So yes, a 30W panel can certainly do that.
That’s one of the half a dozen things you listed lol. You gonna power a computer off a 30W solar panel that realistically will give you about 6W? Power tool batteries?
Sure, a very small one, with a battery. My smartphone will charge off 5W.
I've got a mini Dremel that will charge off 5W USB. It ain't gonna be fast, but it will definitely work.
You're batting 0/3, still want to keep trying?
Look: I plan solar panels, batteries, and a small TV set, so during the apocalypse, I will have my Netflix shows! And with the right EV, I will be one of the few who can still go to Costco!
You see: I'm ready!!
Why wouldn’t you just get Amazon delivery? Come on now!
You underestimate the amount of digital hoarders out there.
Or maybe hoarders overestimate how much and how long they can rely on their digital stuff.
Once you let go of heating and cooling, larger temperature variations are going to do a number on you consumer grade electrical devices. Your solar panels are one heavy hails storm away from destruction, and if we assume climate change is the cause of the apocalypse, you can count on those.
The best way to survive an apocalypse is to rebuild communities with a wide set of skills, and still dramatically lower our quality-of-life AND HEALTH expectations.
You know, you can charge your house? With a large enough battery and enoug PV power you can operate a heat pump off the grid to control the climate of your home.
The feasibility varies a bit, depending on where exactly you live, but there are definitely useful things you can do with solar power and batteries.
Nothing that a 30W panel can manage though. And I definitely agree to your point about rebuilding communities.
Yeah while home battery systems and a portable 30W panel are a bit different haha.
I’ve got solar with a 42kWh home battery system, with a petrol generator backup that can power the whole house via a change-over switch, but even that in an apocalypse isn’t gonna do much - especially when, like in a blackout now, I’m the only house on the street with lights on.
Ofc, that's on a whole different level.
Your 42 kWh is huge. Pair that with an approriately sized roof solar panel, and you won't need a grid much. Seriously, look into that. Not even for living off the grid, but for financial reasons.
Though yeah, having the lights on and appliances running, might paint a target on your house in an apocalyptic scenario. But nobody's forcing you to use the lights, and a heat pump with ground water or earth collector as a source is pretty stealthy. So you can sit in a dark, but warm, house.
My house is quite rural and I have a water well with a battery backup for the pump and UV filter. The battery lasts for about 5-6 days depending on use. I can charge the battery from the grid or with solar.
If the cities get nuked, my well system will still function.
Can you repair it if it breaks?
We did a battery backup system! I think we'll do panels next. Did you buy enough panel generation to replace it as you use it?
We bought the ecoflow batteries; we haven't shopped around for panels yet. I was hoping their panels were competitively priced so we could kind of just plug 'n play.
Hmm. So let's talk resilience; lighting, battery power tools, refrigeration, Mobility (mountain eBikes, with solar recharging would make for great post apocalyptic transportation), and many more things.
That's a pretty ignorant thing to say.
gasmask, radiation tablets and suits, a working moter bike and a ton of gas are higher on my list.
How long does gasoline keep?
2 or so year, but that long enough to get you to where you need to, if it take over 2 years of driving to get what you need and you can't find any more, sorry but you were probubly fucked from the get go
That is where a diesel bike and maybe a diesel truck as well would come in handy. You can continue making biodiesel long term, and use the engine for generator power in a pinch. You can even go with mechanically controlled engines and not have problems with EMP to be extra prepared.
Ehh, disagree. We have a battery backup system (they charge from the electric lines) for our house because we have a well instead of septic lines, so when the power goes out we don't have water. Our next big purchase will be panels to charge the batteries as further backup.
