PART TWO
6. GENERATORS: BUY THE RIGHT KIND OF POWER, NOT THE BIGGEST MARKETING CLAIM
Now we get to the equipment that attracts a lot of attention, a lot of money and an alarming amount of wishful thinking.
A generator can be invaluable during a prolonged outage. It can also be the wrong purchase for your home, your budget or your actual needs.
First, understand the difference.
Option A: Portable battery power station
Quiet, rechargeable and suitable for indoor use when operated according to the manufacturer's instructions. Ideal for phones, lights, laptops, radios and some medical or communications equipment, depending on the specifications.
The limitation? Stored energy is finite. Running a space heater, kettle or other high-draw appliance can exhaust a modest battery surprisingly quickly.
Option B: Fuel-powered portable generator
Potentially useful for longer outages when you have a suitable outdoor location, sufficient fuel and a carefully planned electrical setup.
The limitations are noise, maintenance, fuel availability, emissions and fire hazards. It must operate outdoors, at least 20 feet from the house as a general U.S. Consumer Reports recommendation, with exhaust directed away from windows, doors and air intakes. Follow applicable local requirements and the manufacturer's instructions.
Option C: Permanently installed standby generator
A possible solution for homeowners who need substantial backup power and can afford professional installation, maintenance and fuel arrangements.
This is not a plug-and-play purchase. Electrical integration, ventilation, local permits and safe transfer equipment matter.
The independent tests you should read before spending a dollar
Don't buy an emergency power system based on a glossy advertisement, a viral video or a manufacturer's claim that its battery will power your entire house.
Start with independent testing.
1. Wirecutter — portable power station testing
Look for independently tested portable battery stations, not just marketing comparisons. Wirecutter's power-station reviews examine real-world performance and suitability for emergency use. Its 2025 guide is a useful starting point, but check for newer testing before purchasing.
Search its current reviews and buying guides for generators, power stations and related emergency equipment. Check exactly which products it has tested; don't assume it has independently tested every category or model.
3. Stiftung Warentest — Powerstation test
Germany's consumer-testing organization examined 11 portable power stations in 2023, evaluating factors including usable output, charging performance, handling and safety. Its January 2026 update reiterated the results. Importantly, these were battery power stations, not a comprehensive test of fuel-powered generators.
4. Consumer Reports — generator buying guide
Particularly useful when comparing fuel-powered generators, standby systems and battery stations. Its buying guidance discusses output, efficiency, usability and carbon monoxide safety. Check its latest ratings and safety requirements before making a decision.
Important: These sources do not all test the same equipment. A battery power station and a gasoline generator are fundamentally different products. Never treat a high score in one category as evidence that a product will perform well in another.
The five numbers that matter more than the advertising
What to check | Why it matters |
|---|---|
Battery capacity, in Wh | How much energy is stored |
Continuous output, in W | Which appliances the unit can run continuously |
Surge output | Whether it can handle brief starting loads |
Charging time and options | How quickly you can replenish the supply |
Tested usable energy | How much electricity you actually get after losses |
Here's the calculation many buyers overlook.
A 1,000 Wh battery powering a device that consumes 50 W would theoretically run it for 20 hours. In practice, conversion losses, the battery's usable capacity and the device's actual consumption reduce that figure.
A 1,000 W appliance does not magically run for 20 hours on a 1,000 Wh battery. The theoretical maximum is around one hour before losses, assuming the station can supply the required continuous output.
And a 2,000 W battery inverter does not necessarily store 2,000 Wh of energy. Power and energy are two different specifications.
Your generator safety rules are non-negotiable
Never operate a fuel-burning generator in a home, garage, basement, shed or other enclosed or partially enclosed space.
Keep it outside and well away from openings; follow the required separation distances and local rules.
Install and maintain appropriate carbon monoxide alarms.
Never connect a generator directly to a household wall outlet. A qualified electrician should install suitable transfer equipment for connection to household wiring.
Never refuel a hot generator or store fuel carelessly.
Keep generators dry and operate them only in conditions allowed by the manufacturer.
Test and maintain equipment before an emergency, not for the first time during one.
Carbon monoxide poisoning kills. A generator that keeps the lights on is not a good deal if it puts your family at risk.
For apartment dwellers, a battery station, power banks, lighting and a safe plan to relocate may be considerably more practical than a fuel generator.
And here's another uncomfortable truth: a portable battery is not a substitute for a building's heating system. If your home depends on electrically powered central heating, a small power station may keep your phone alive while doing almost nothing to keep the apartment warm.
7. DO THE MATH BEFORE THE BLACKOUT DOES IT FOR YOU
Your basic blackout planner
Estimate a starting point for essential electricity and drinking water. These are planning estimates, not a complete household risk assessment.
Estimated electricity use per day
12 Wh
20 Wh
10 Wh
Battery sizing: add a margin for conversion losses and uncertainty, and confirm that continuous and surge output meet your devices' requirements. Medical devices may need a dedicated, professionally assessed backup plan. This calculator does not estimate heating, cooking, refrigeration or water-pumping loads unless you include them under other devices.
Run this calculation with realistic loads. Then test your assumptions.
Can you recharge your battery if the grid remains down for several days? Will solar panels work where you live during winter? Can you safely store and use fuel? Does your household include anyone whose medical needs make a prolonged outage especially dangerous?
The objective isn't to buy the biggest machine you can afford. It's to identify the failure that would hurt you most and reduce that risk.
8. PREPARE TOGETHER, NOT JUST ALONE
Individual preparedness matters. Community resilience matters just as much.
A neighbour may have a generator but no way to contact an elderly relative. Another may have a working radio, a warm room and enough supplies to help someone else. A third may have medical training or a vehicle.
Those resources become more valuable when people know how to coordinate them.
Before an emergency:
Learn who in your building or neighbourhood may need extra assistance.
Identify nearby emergency shelters, warming centres and official information points.
Agree on a family meeting place and an out-of-area contact.
Ask building management about backup power, water systems, elevators and emergency procedures.
Know when to leave rather than trying to tough it out.
Do not put yourself or others in danger by entering damaged buildings, approaching downed power lines or improvising electrical connections.
And don't assume that everyone can afford a power station, a generator, a second refrigerator or a week's worth of supplies. Resilience cannot become another luxury good available only to people with spare cash.
Public authorities have responsibilities here. So do building owners, utility operators, employers and elected officials.
9. THE GOVERNMENT TEST: WHAT HAPPENS WHEN THE GRID FAILS?
Preparing households is necessary. Pretending household preparedness can compensate for every institutional failure is irresponsible.
A city should know which facilities are most critical, how quickly they can be repaired, where backup capacity exists and which services can operate independently. It should test emergency communications, establish clear public guidance and make practical assistance available to vulnerable residents.
Energy systems also need redundancy. When one enormous facility supplies an entire urban district, a single attack or technical failure can affect thousands of households. Distributed generation, strategically placed backup systems, protected infrastructure and the ability to isolate failures can reduce the consequences.
That does not mean every city can decentralize overnight. Engineering constraints, funding, fuel supplies, workforce shortages and security requirements are real. But a credible resilience plan should explain what is being done, what remains vulnerable and how progress is measured.
The public deserves more than reassurances that everything will probably be fine.
It deserves answers:
Which critical services can function without the main grid?
How long can hospitals and water systems operate on backup power?
How quickly can damaged equipment be replaced?
What support exists for residents who cannot evacuate or prepare independently?
Has the plan been tested under realistic conditions?
These are not partisan questions. They are basic questions of public safety.
We cannot promise to stop every dictator, prevent every disaster or eliminate every outage. We can demand better protection of critical infrastructure, stronger emergency planning and more honest communication about risks.
And we can refuse to let the limits of government action become an excuse for doing nothing ourselves.
10. YOUR 72-HOUR BLACKOUT CHALLENGE
Don't wait for a warning siren to discover that your emergency kit consists of a half-dead flashlight and three mysterious batteries.
Conduct a realistic household exercise.
Blackout readiness checklist
You don't need to turn your home into a survival compound. You need to know what you would do if the electricity disappeared tonight, tomorrow, or for several days.
Practice the basics. Learn where your plan breaks. Fix the weaknesses while you still have time.
THE BOTTOM LINE: ADAPT OR BE AT THE MERCY OF EVENTS
Winter is coming. It comes every year. What changes is the condition of the systems we depend on, the threats they face and our willingness to prepare for predictable disruptions.
People living through war deserve more than platitudes about resilience. They deserve protection, functioning infrastructure, humanitarian support and a genuine effort to stop attacks on civilians and essential services.
Everyone else should pay attention, too.
You don't need to believe that catastrophe is inevitable. You need to understand that low-probability, high-impact events can still justify sensible preparation, especially when the consequences of being unprepared are severe.
A blackout kit will not end a war. A battery station will not protect a power plant. A pantry full of food will not repair a damaged grid.
But water, light, information, essential supplies, a workable plan and a community that looks after its members can prevent a bad situation from becoming a disaster.
We cannot personally disarm every dictator. We cannot eliminate every threat. We can stop making ourselves more vulnerable than necessary.
Hope for the best. Prepare for the worst. And never confuse being prepared with giving up.
The fight for a more resilient future starts long before the lights go out.
