Accountability
Every article on WattBackup is published under this name. That is deliberate: a site that tells you which generator to buy should tell you who is answerable when the figure is wrong.
Articles here are drafted with AI assistance and every number in them is checked against a primary source by a person before publication. Both halves of that sentence are stated openly in the editorial policy, along with what counts as an admissible source and what happens when a correction is needed.
Alvaro is not a licensed electrician, and nothing published on this site substitutes for one. WattBackup explains what equipment exists, what it costs and which code applies, then refers you to a professional. That boundary is set out in the terms of use.
Articles
How Many kWh Does a House Use During a Full Outage Day?
Your normal electricity bill does not describe the appliances you will keep running in a blackout. Build a daily load budget and see which essential services are still missing from the subtotal.
Home Battery Backup vs Standby Generator: Which Is Cheaper Over 10 Years?
A cheaper installation can become a more expensive backup once service and replenishment are included. Compare equivalent household tasks and see what the ten-year subtotal still leaves unpriced.
How to Prepare a Home Office for Unplanned Outages
An extra monitor adds an energy demand that is easy to overlook. Build a work plan around documented loads, saving your files and an internet fallback.
Dual Fuel vs Tri Fuel Generators: Which Makes Sense for Home Backup
A third fuel option adds a supply route, but its power rating still matters. Compare documented output losses and the storage or service conditions behind each option.
Interlock Kit vs Transfer Switch: Cost, Code Compliance and Install Time
Two installation prices can cover different work. See how panel-specific compatibility, permit exclusions and documented site-time estimates change the comparison.
Generator Backfeeding: Why It Is Dangerous and Never Worth It
A household output rating does not describe the hazard on an unintentionally energized utility line. Understand the documented risks and the isolation requirements to discuss with a licensed electrician.
Well Water and Power Outages: How to Get Water Without a Pump
Stored water, a compatible hand pump and an approved electrical backup solve different parts of a well-water outage. See how much to store and which conditions matter before relying on the well.
How to Keep Your House Warm During a Winter Power Outage
Retaining heat, powering a compatible system and finding somewhere heated are different parts of the plan. See the electrical limits before relying on a battery or a furnace blower calculation.
Inverter Generator vs Conventional Generator: Noise, Fuel and Sensitive Electronics
A noise rating needs its test distance, and a runtime claim needs its actual load. Compare documented examples without mistaking different test conditions for guaranteed fuel savings.
How Far Should a Generator Be From the House? CO Safety Distances
Portable CO guidance and fire clearances answer different questions. See what each distance measures and why standby wall spacing needs a professional assessment.
Do You Need a Transfer Switch for a Portable Generator?
An inlet, an interlock and a transfer switch perform different jobs. See which connection your household loads need and what an installation quote should include.
How Long Can You Safely Run a Generator Continuously?
A full tank does not mean you can skip an oil check or service stop. Compare the separate fuel, inspection and maintenance clocks in manufacturer documents.
How Long Do Power Outages Usually Last? US Utility Data by State
The question hides two different ones. A single interruption averages just over two hours in normal operation and 7.2 hours once storms are counted, while the whole year came to 11 hours per customer in 2024.
Power Outage Checklist: What to Do in the First 60 Minutes
Most outage checklists have no clock on them. This one does: about four hours of refrigerator, 24 to 48 of freezer, and the federal reliability data that says an average US customer lost 11 hours to outages in 2024, nearly nine of them to storms.
How Much Fuel Does a Generator Use per Hour? Gasoline, Propane and Diesel
Every page answers this with one number, and one number cannot answer it. A 10 kW standby burns 0.97 gal/h of propane at half load and 1.48 at full load, and going from half to full costs 1.5 to 1.8 times the fuel, not twice.
What Size Generator to Run a Refrigerator, Freezer and Furnace at Once?
The first page recommends a 6,000 to 8,000 W generator, and the figure carrying that recommendation costs a gas furnace as if it were an electric heater. The two loads anybody publishes come to 575 W.
What Size Generator Do I Need? Sizing by House Size, Loads and Budget
Every result on page one is a calculator, they contradict each other on the only rule that matters, and none asks your elevation. Generac settles the rule in its own manual and publishes the derating in the same table as the wattage: 3.5 per cent for every thousand feet.
UPS vs Portable Power Station for Home Office Backup
Nine of the first ten results are written by someone selling one of the answers. The number that settles it is in Intel's ATX design guide: 16 ms of PWR_OK hold-up.
How to Recharge a Power Station During a Multi-Day Outage
Every page on this answers solar panels and stops. Five manufacturers publish the figures that decide it: a solar input ceiling that varies five and a half times, a refill quoted in hours of sunlight rather than hours, and a wall charger whose speed was decided when you bought the box.
Can You Use a Power Station Indoors? Ventilation and Safety Explained
Every page answers this with zero emissions and a six-inch rule. We opened four manuals instead: two say the device is for indoor use only, and the only clearance figure anyone publishes is 30 cm, in a troubleshooting table.
How Long Does a Portable Power Station Last? Cycles, Calendar Ageing and Warranties
Cycles are the wrong unit for a machine that spends its life switched off in a cupboard. At one cycle a month even the worst rating here is forty-two years, and the only commitment anyone makes is two to five.
Do Portable Power Stations Work in Freezing Temperatures?
Using one below freezing and recharging one below freezing are different questions with different answers. Four manufacturer specification pages, and the charging floor does not move.
LiFePO4 vs NMC Power Stations: Cycle Life, Weight and Cold Weather
Everything written about these chemistries is written about cells and then applied to products. Taken to three manufacturer specification pages, all three of the usual conclusions come apart.
Pure Sine Wave vs Modified Sine Wave: Which Appliances Actually Care
The lists of what modified sine wave breaks are usually unsourced. We read what three inverter manufacturers put in their own manuals, and the interesting thing is how little the lists overlap.
