Key takeaways
- Add up your real loads first: Clamp a meter on your panel or tally nameplate watts for the fridge, well pump, furnace blower, and a few circuits of lights. Well pumps and compressors need surge headroom, so buy roughly 25% above your running total rather than shaving it close.
- Decide how power gets inside: Extension cords through a window are a stopgap. A generator inlet box plus a panel interlock kit or a transfer switch is the clean solution, and it needs a licensed electrician and a permit in most jurisdictions. Never backfeed a dryer outlet.
- Dual fuel earns its keep: Propane stores for years without stabilizer and starts clean in cold weather; gasoline gives you more peak output. Having both means a fuel shortage doesn’t end your outage plan.
- Watch the noise and the neighbors: Inverter units in ECO mode throttle down to load and are dramatically quieter than open-frame conventional engines. If you’re on a tight lot, that difference matters more than a few hundred watts.
- Plan the maintenance and the moving: Check oil capacity, filter access, and whether the wheels are solid or pneumatic. Build or buy a level gravel pad with a rain canopy that keeps the unit fully open on all sides for airflow and exhaust.
What's inside
The first time the lights go out for more than a few hours, you learn exactly how much of your house depends on a wall outlet. The fridge starts sweating, the sump pump goes quiet, the furnace blower stops, and suddenly you’re doing mental math on how long a freezer holds temperature. Most people then buy the first generator they can find in stock, and end up with something either too small to matter or so big it never leaves the garage. Sizing is where nearly every backup power project goes sideways.
This guide comes from the perspective of someone who has actually run conduit, mounted an inlet box, and dragged a 200-pound machine across wet gravel at 2 a.m. Below you’ll find the units worth your money in 2026, plus how to match wattage to your real loads, what “transfer switch ready” actually requires on your end, and where a battery unit beats gas outright. Whatever you pick, the same rule applies: engines run outside, well away from windows and doors, always.

The Best Portable Generator For Home Backup Power (2026)s Reviewed
DuroMax XP13000EH Dual Fuel Generator
This is the workhorse pick for whole-home coverage: 13,000 watts on gas, propane capability, electric start, and a 50A outlet that pairs directly with a transfer switch. It’s heavy and it’s loud, but it will start a well pump and a central AC compressor without flinching.
Westinghouse 12500 Watt Dual Fuel Generator
Westinghouse hits a nice balance of output, build quality, and dealer support, and the remote electric start is genuinely useful when it’s sleeting. Fuel gauge, hour meter, and clearly labeled outlets make it an easy unit to live with over multiple outages.
DuroStar DS13000MX Dual Fuel Generator
Same class as the XP13000EH with a 500cc engine and remote start, often at a slightly friendlier price. If you want maximum watts per dollar for a transfer-switch install and don’t mind the size, this is the value play.
Jackery HomePower 3600 Plus Power Station
A 3,584Wh LFP battery with 3,600W output that runs indoors, silently, with zero exhaust risk, and expands toward 21kWh if you add packs and panels. It won’t carry central AC, but for fridge, internet, medical devices, and lights it’s the most livable option on this list.
Oxseryn 4400W Inverter Generator
An open-frame inverter that keeps things portable and reasonably quiet in ECO mode, with a 30A RV outlet and clean power for electronics. Best used as an essentials generator or dual-purpose camper unit rather than a whole-house solution.
Frequently Asked Questions
How many watts do I need for home backup?
Essentials only (fridge, lights, modem, a couple of fans) fit inside 3,000 to 4,500 watts. Add a furnace blower and well pump and you’re at 7,500. Central air or an electric range pushes you into the 10,000 to 13,000 range.
Can I install a transfer switch myself?
Panel work is not a beginner DIY job, and most areas require a licensed electrician and inspection. You can absolutely handle the prep: choosing the inlet location, running the exterior conduit path, and building the generator pad.
Is a battery station really enough during an outage?
For a day or two of essential loads, yes, especially with solar to recharge. Battery units win on noise, indoor safety, and zero maintenance; gas wins on multi-day runtime and heavy motor loads.
How do I store fuel safely?
Use approved containers, rotate gasoline every few months, and add stabilizer. Propane tanks store far longer and belong outside, upright, in the shade, never in a basement or attached garage.
Final Thoughts
If you want one machine to cover the whole house, the DuroMax XP13000EH or the Westinghouse 12500 Watt dual fuel are the two I’d wire to a transfer switch and stop worrying about. If your outages are short and you’d rather have silence and no fuel to babysit, the Jackery HomePower 3600 Plus is the smarter buy, and it’s the one you can safely run inside.
