Hey everyone, welcome back to My Weird Prompts. I am Corn, and I am sitting here in our living room in Jerusalem with my brother.
Herman Poppleberry, at your service. It is a bit of a heavy afternoon here, Corn. The hum of the city feels a little different when the news cycle is as intense as it has been lately.
It really does. And our housemate Daniel has been feeling that too. He sent us a prompt earlier today about something that has been on all of our minds. He has been thinking about digital preparedness, specifically how we keep our lives running when the lights go out or the connectivity drops. He mentioned his experience with the tensions we saw back in April of twenty twenty-four and how that changed his perspective on being ready for anything.
It is a logical progression, honestly. We have talked about the psychological side of preparedness before, but the technical side is where I really get to geek out. Daniel is asking about power stations. Not just the little pocket chargers we use for our phones, but the heavy-duty units that can keep a home office or a small kitchen running during an outage.
Right. He is looking for a buyer's guide. What capacity do we need? Which brands are actually reputable in twenty twenty-six? And most importantly for you, Herman, how do we keep these things healthy when they are mostly just sitting there waiting for an emergency?
Oh, that last part is the real kicker. It is the paradox of the emergency battery. You want it full so it is ready, but keeping a battery at one hundred percent all the time is essentially a slow-motion suicide for the chemical cells inside. We will definitely dive deep into that.
Let us start with the basics for anyone who is new to this. When we say power station, we are talking about a portable power station, sometimes called a solar generator. It is basically a giant battery in a box with an inverter that lets you plug in regular household appliances using standard AC outlets.
Exactly. And the market has matured so much in the last few years. Back in twenty twenty-two or twenty twenty-three, you still saw a lot of older lithium-ion chemistries. But today, in twenty twenty-six, if you are buying a power station for emergency preparedness, you absolutely must look for Lithium Iron Phosphate, or LFP. It is sometimes listed as LiFePO4.
Why is that the dealbreaker for you?
Longevity and safety, Corn. A standard lithium-ion battery like the one in your phone might be rated for five hundred to eight hundred charge cycles before it loses significant capacity. An LFP battery is typically rated for three thousand to four thousand cycles. If you used it every single day, it would last you ten years. For someone like Daniel, who wants it for emergencies, that battery will likely outlive the plastic casing it is housed in. Plus, LFP is much more thermally stable. It is way less likely to catch fire if it is punctured or if the electronics fail.
That makes total sense for a device you are keeping under your desk or in a closet. So, let us talk capacity. Daniel asked what capacity we should look for. This is where people get confused with the numbers. We are talking about Watt-hours, right?
Yes, Watt-hours. Think of Watt-hours as the size of the fuel tank. If you have a one thousand Watt-hour station, it can theoretically power a one hundred Watt device for ten hours. In reality, you lose about fifteen to twenty percent of that to the inverter efficiency, so it is more like eight hours.
So, for a typical household here in Jerusalem, if we are worried about a twenty-four-hour power outage, what is the sweet spot?
It depends on your mission. If your mission is just keeping the Starlink Mini running and charging a few phones, you can get away with a small unit, maybe three hundred to five hundred Watt-hours. We know the Starlink Mini draws about twenty-five to forty Watts on average. A five hundred Watt-hour station would keep you online for over ten hours easily.
But Daniel mentioned a family or a longer-term situation.
Right. If you want to keep a full-sized refrigerator running, you need to step up. A fridge doesn't run constantly, but when the compressor kicks on, it draws a lot. For a twenty-four-hour period, a one thousand Watt-hour station is the bare minimum for a fridge and some lights. If you want real peace of mind, you are looking at the two thousand Watt-hour category. That is where you start seeing the big boys like the EcoFlow Delta series or the Bluetti AC series.
Let us get specific on brands. Daniel asked for reputable names. Given the current landscape in early twenty twenty-six, who is leading the pack in terms of reliability and support?
EcoFlow is still the giant in the room. Their Delta Two Max and the newer Delta Pro series are incredibly polished. They have some of the fastest charging speeds in the industry. You can plug a Delta Two Max into a wall outlet and go from zero to eighty percent in about an hour. That is crucial if you only have a short window of power between outages to top things up.
I have also heard good things about Anker lately. They moved into this space pretty aggressively.
They did. The Anker Solix series, specifically the C-one-thousand, is a fantastic mid-range choice. Anker's big selling point is their build quality and their five-year warranty, which is quite generous in this industry. They use high-quality LFP cells and their thermal management is excellent. Then you have Bluetti. They are the ones who often experiment with more industrial-grade features. Their AC-two-hundred-L is a workhorse. It has a massive surge capacity, which means it can handle the initial spike of power when you turn on something heavy like a power tool or a large coffee machine.
What about Jackery? They used to be the name everyone knew.
Jackery is the reliable, simple option. They were a bit slow to move to LFP chemistry across their whole line, but their newer Explorer Plus series has finally caught up. They are great for people who don't want to mess with apps or complex settings. It is very much a plug-and-play brand. But for someone like us, or Daniel, who wants more data and control, EcoFlow or Bluetti usually offer more features.
You mentioned apps. Is that actually useful or just another thing to break?
In an emergency, it is actually a godsend. Most of these units have Bluetooth and Wi-Fi. You can sit on your couch and see exactly how many Watts your fridge is drawing and how many hours of battery life you have left. You can also adjust the charging speed. If you are running on a small portable generator, you might want to slow down the AC charging so you don't trip the generator's breaker. That kind of control is vital.
Okay, let's pivot to the technical deep dive Daniel asked for. This is the Dr. Poppleberry special. How do we balance keeping the battery topped up for an emergency while maintaining its health? Most people think you just leave it plugged in all the time, but you mentioned that is bad.
It is the biggest mistake people make. Lithium batteries, even the hardy LFP ones, hate being at one hundred percent state of charge for long periods. When a battery is fully charged, the lithium ions are all crammed into the anode, creating high voltage stress. Over months and years, this causes the electrolyte to decompose and the capacity to fade.
So if Daniel keeps his power station at one hundred percent for a year, waiting for a war or an outage, what happens?
He might find that when he actually needs it, that two thousand Watt-hour battery only gives him fifteen hundred Watt-hours. Or worse, the internal resistance has increased so much that it can no longer handle high-power loads.
So what is the Poppleberry Prescription?
The gold standard is the eighty-twenty rule, or even the seventy-thirty rule for long-term storage. If you know you aren't going to use it for a few weeks, keep it at about sixty to eighty percent. Most modern power stations from EcoFlow or Anker actually have a setting in the app for this. You can set a charging limit. You tell the unit, hey, even if you are plugged into the wall, don't go above eighty percent.
But wait, Herman. If the power goes out at two in the morning, Daniel is starting with twenty percent less capacity than he could have had. In an emergency, every Watt-hour counts.
That is the trade-off. However, because LFP charges so fast, if you see the situation deteriorating, you can bump that limit back up to one hundred percent in less than thirty minutes. It is about situational awareness. If things are quiet, keep it at eighty. If the news looks bad, or if there is a storm coming, top it off to one hundred. Just don't leave it at one hundred for six months straight.
What about the bottom end? Is it okay to run it down to zero?
Absolutely not. Running a lithium battery to true zero can be fatal for the cells. Most power stations have a built-in buffer where zero percent on the screen isn't actually zero percent in the chemistry, but you still shouldn't let it sit empty. If you use it during an outage and it hits zero, you must recharge it as soon as possible. If a battery sits at zero for a month, it might never wake up again.
So, for someone living in a high-tension area like we are, what is the maintenance routine? Once a month, do you discharge it?
Yes. I recommend a shallow cycle every three months. Discharge it down to twenty percent by running some household appliances, then charge it back up to your storage limit. This helps the Battery Management System, or BMS, stay calibrated. The BMS needs to see the battery go through its range so it can accurately calculate how much life is left. If you never use it, the percentage meter on the screen can become inaccurate, which is the last thing you want during a blackout.
That is a great point. You don't want to think you have five hours left when you actually have two. Let's talk about second-order effects. If everyone in a neighborhood has these power stations, does that change the dynamic of a grid failure?
It is a fascinating thought experiment. On one hand, it reduces the immediate panic. People can stay informed, keep their phones charged, and keep their food from spoiling. On the other hand, when the grid comes back on, if thousands of these units all start fast-charging at two thousand Watts simultaneously, it could actually trip the grid again. It is called a cold-load pickup problem.
I hadn't thought of that. It is like everyone turning their air conditioners on at the exact same moment.
Exactly. That is why I always suggest that when the power comes back, you should manually lower your charging speed if your unit allows it. Be a good grid citizen.
Let's talk about the solar side of this. Daniel's prompt focused on power stations, but these are often sold as solar generators. How realistic is it to rely on solar panels in a city like Jerusalem during a conflict?
It is tough. If you are in an apartment, you are limited by balcony space. But even a small one hundred Watt portable panel can be a lifesaver. It won't run your fridge, but it will keep your communication devices and lights going indefinitely. The key is to get panels that match the voltage input of your station. Most brands have their own proprietary panels, which are easy but expensive. You can use third-party panels, but you have to check the Open Circuit Voltage. If you plug a forty-volt panel into a station that only handles thirty volts, you will fry the charge controller.
So, for Daniel, if he is buying a one thousand Watt-hour station, should he get two hundred Watts of solar?
That is a good ratio. Two hundred Watts of solar will give you about eight hundred to one thousand Watt-hours of charge on a sunny day here. That basically replaces what you used the day before. It makes you energy-neutral for basic needs.
We should also mention temperature. We are lucky here that it doesn't get as cold as, say, Chicago, but it does get hot.
Heat is the enemy. Never, ever charge your power station in direct sunlight. The solar panels should be in the sun, but the battery should be in the shade, ideally behind a wall or under a cover. Charging a battery generates its own heat, and if the ambient temperature is already forty degrees Celsius, the BMS will throttle the charging speed to a crawl to prevent a fire.
And what about the noise? You mentioned earlier that these things have fans.
They do. When you are pulling a lot of power or charging fast, those fans can be quite loud. It sounds like a loud gaming laptop. If you are sleeping in a small room with one of these, it is something to consider. Some units have a quiet mode that limits the power output to keep the fans off.
Let's summarize the buyer's guide for Daniel and our listeners. If you are looking for a solid setup in twenty twenty-six, what is the Poppleberry-approved list?
For a small, ultra-portable setup, maybe for a grab-and-go bag: The EcoFlow River Two series. They are light, use LFP cells, and are very reliable. For a home-office setup to keep your laptop, monitor, and Starlink running through a work day: The Anker Solix C-one-thousand. It is the perfect balance of size and power. And for the full-home preparedness setup: The Bluetti AC-two-hundred-L or the EcoFlow Delta Two Max. Those give you enough capacity to be truly comfortable for twenty-four to forty-eight hours.
And the maintenance takeaway?
Keep it at eighty percent. Set a reminder on your phone to check it every three months. Use it to power your TV for an evening once a quarter just to keep the electrons moving. And always, always read the manual regarding the maximum surge wattage. Don't try to plug a space heater into a small power station. You won't break it, but the safety fuse will trip and you will be sitting in the dark wondering why your expensive battery isn't working.
It is about knowing your tools. Just like we talked about in the passkeys episode a few weeks ago, digital preparedness isn't just about owning the tech; it is about understanding the systems. If you don't know how to use your power station when you are stressed and the sirens are going off, it is just an expensive paperweight.
Beautifully put, Corn. Practice when things are calm. Do a dry run. Unplug your router and your Starlink and see how long your battery actually lasts. You might be surprised.
I think we should also touch on the future. We are talking about LFP today, but what is on the horizon? Daniel is always looking for the next thing.
Solid-state batteries are the holy grail. We are starting to see the very first prototypes in the portable power space. They would be half the weight and twice the capacity, and virtually impossible to catch fire. But they are still prohibitively expensive in twenty twenty-six. Maybe in another three or four years, that will be the standard. For now, LFP is the sweet spot of the curve.
It is amazing how fast this has changed. Five years ago, having a kilowatt-hour of power in a box you could carry with one hand was science fiction. Now, it is something you can buy at a local electronics store.
It really is. It changes the power dynamic, literally. It moves us away from total dependence on a centralized, often vulnerable grid. Especially in a place like Jerusalem, that kind of personal resilience is worth its weight in gold.
Well, I think we have given Daniel a lot to chew on. From the chemistry of LFP to the eighty-twenty charging rule, there is a lot of nuance here.
I hope it helps him feel a bit more secure. Preparedness isn't about being afraid; it is about being capable. When you know you have the power to keep your family connected and your food cold, the weight of the world feels just a little bit lighter.
Absolutely. And if you are listening and you found this helpful, we would really appreciate it if you could leave a review on your favorite podcast app. It really does help other people find us and join our little community of curious minds.

Thanks to Daniel for sending this in. It is a topic that hits close to home for all of us living here. We will be back next week with another exploration of the weird, the technical, and the deeply human.
Until then, stay curious and keep your batteries healthy.
This has been My Weird Prompts. Thanks for listening.
Take care, everyone.
So, Herman, be honest. Do you actually have our power station at eighty percent right now?
Corn, I am offended you even have to ask. It is sitting at exactly seventy-nine percent. I checked it before we started recording.
Of course you did. I should have known better.
Precision is a virtue, brother. Precision is a virtue.
Alright, let's go see what Daniel is cooking for dinner. I hope it doesn't require the microwave, or you'll have to adjust your seventy-nine percent.
For a good meal, I am willing to make an exception. Let's go.
See you all next time.
Goodbye!
One last thing, I forgot to mention, if people want to reach out with their own prompts, they can use the form on the website. We actually read all of them.
We do. Some of the best episodes we have ever done came from listeners just like Daniel. So don't be shy.
Exactly. Alright, now we are actually going. Bye!
Bye!
