Key takeaways
- Running watts, not peak watts: Peak is a two-second surge rating. Add up the continuous draw of your fridge, freezer, well pump, and furnace blower, then add roughly 30% headroom and shop by the running number.
- Fuel strategy: Gasoline goes stale and gets scarce during storms. Propane stores for years in your existing grill tanks. Natural gas runs indefinitely if your home already has a line. Dual and tri-fuel units let you pivot mid-outage.
- Inverter vs. open frame: Inverters produce clean sine wave power that won’t upset laptops, smart TVs, or variable-speed HVAC boards. Conventional open-frame units push more raw watts per dollar but belong on a jobsite, not next to your electronics.
- Transfer switch readiness: If you want to power hardwired circuits instead of stringing cords, look for an L14-30 or 50A outlet and plan for a licensed electrician to install an interlock or transfer switch. Never backfeed through a dryer outlet.
- Weight, wheels, and startup: Anything over 200 pounds needs real never-flat wheels and a lift handle. Remote electric start is genuinely useful when the unit lives on the far side of a wet yard.
What's inside
Anyone who has wired a shed, framed a deck, or ridden out a three-day outage knows the moment the lights die is the moment you find out what your backup plan is actually worth. The generator aisle makes that decision harder than it should be: wattage numbers that mean two different things, fuel options stacked three deep, and spec sheets that quietly skip the part about how loud the thing is at 2 a.m. when your neighbor is trying to sleep.
This guide comes from the perspective of someone who has hauled these units in and out of a pickup bed, changed the break-in oil, and run extension cords through a partly open window in the rain. Below you’ll find inverter units light enough for one person to move, dual-fuel workhorses sized for a transfer switch and a whole panel, and a tri-fuel option that ties into a natural gas line so you never touch a jerry can again. I’ve noted where each one earns its spot and where the tradeoffs land.

The Best Brand Of Portable Generator (2026)s Reviewed
Westinghouse 14500 Peak Watt Tri-Fuel Generator
The tri-fuel setup is the closest thing to a standby generator you can still roll into a garage, and running it off a house natural gas line means unlimited runtime without a single fuel can. Pair it with a properly installed transfer switch and it will carry a central AC unit alongside the essentials.
Westinghouse 12500 Watt Dual Fuel Generator
This is the sweet spot for most homes that want serious backup without the natural gas plumbing. Remote start works reliably from inside the door, and propane operation keeps the carburetor clean if the unit sits unused for months between outages.
DuroMax XP13000EH Dual Fuel Generator
DuroMax builds these around a big, unfussy engine with a heavy steel frame, and it shows in how little the unit walks around under load. It’s a genuine two-person lift into a truck, but the 50A outlet and copper windings make it a strong pick for whole-home backup and long RV stays.
Oxseryn 4400 Watt Inverter Generator
An open-frame inverter is a smart compromise: you get clean power for sensitive electronics at a weight one person can actually manage, and ECO mode drops the engine speed to a hum when the load is light. The 30A RV outlet makes it an easy trailer companion.
AMERISUN 4500W Open Frame Inverter Generator
Parallel capability is the real story here, since two of these linked together roughly double your capacity without buying one heavy unit. Built-in CO shutoff is a safety feature I now consider non-negotiable on anything running near a house or campsite.
Frequently Asked Questions
How far from the house should a generator run?
At least 20 feet, with the exhaust pointed away from doors, windows, and soffit vents. Carbon monoxide is odorless and has killed people running units in open garages, so treat the distance rule as absolute.
Do I lose power output on propane?
Yes, typically 10 to 12 percent compared to gasoline. Size your unit based on the propane figure if that’s your primary fuel, and you’ll never be caught short.
How often does a generator need maintenance?
Change the break-in oil after the first 20 hours, then every 50 to 100 running hours. Off-season, run it under load for 20 minutes monthly and either stabilize the fuel or drain the carburetor.
Can one generator run a whole house?
A 12,000 to 14,500 watt unit handles most homes’ essentials plus air conditioning through a transfer switch. Smaller inverters are for circuits and cords, not panels.
Final Thoughts
If your priority is riding out long outages with minimal fuel hassle, the Westinghouse 14500 Tri-Fuel earns the top spot for its natural gas capability. The Westinghouse 12500 Dual Fuel is the better value for most households, while the AMERISUN 4500W is the one I’d load into a truck for a weekend build or a campsite.
