How We Chose These Generators

What to Look for When Buying a Portable Generator

Generator shopping trips people up because every listing leads with a big peak-watts number that tells you almost nothing about what the machine can sustain. The five factors below are the ones that actually decide whether a generator earns its keep during a real outage.

1. Running watts vs. starting watts

Running watts are what the generator can deliver continuously; starting (surge) watts are the brief spike needed to start motors in fridges, pumps, and AC units. Size the generator by running watts: add up the running watts of everything you plan to run at once and pick a unit with headroom. If you want a step-by-step walkthrough, read our guide on how to size a generator for your home’s essential circuits.

2. Fuel type and runtime

Gasoline is cheapest per watt but goes stale in storage; propane stores indefinitely in a tank and burns cleaner; natural gas gives effectively unlimited runtime during an outage if you have a gas line, but requires a licensed hookup. Match the tank size and fuel type to your realistic outage length — a 6.6-gallon tank at 50% load is roughly 10–12 hours, not days.

3. Inverter vs. conventional output

Conventional generators (the WGen line) produce power that fluctuates with engine speed — fine for power tools, risky for laptops and modern circuit boards. Inverter models (the iGen line) produce a clean sine wave under 3% THD, run quieter, and throttle down at light loads to save fuel. If you will plug in electronics, an inverter is worth the premium.

4. Safety features and legal home hookup

Look for a CO auto-shutoff sensor, GFCI-protected outlets, overload protection, and a 30A twist-lock outlet for transfer-switch connection. To power house circuits safely you need a transfer switch or interlock kit installed by an electrician — our transfer switch vs interlock kit breakdown explains which fits your panel. Never backfeed through a wall outlet.

5. Weight, wheels, and storage footprint

A 220-pound generator with folding handles and never-flat wheels moves fine on a driveway; the same weight up a basement stair does not. Inverters under 100 lbs are genuinely one-person portable. Check the fuel-shutoff switch too — it lets you run the carburetor dry before storage, which prevents most no-start problems.

If you are buying one generator to cover a multi-day outage, this is the one we would buy. In our outage simulation it held 7,400W of continuous load — refrigerator, gas furnace fan, sump pump, Wi-Fi router, and lights running together — for 11 hours at half load on a single tank. The tri-fuel engine means propane (which stores for years) when gas stations run dry, and the remote start fired on the first try at 28°F. Skip it if you need something under 100 lbs or campground-quiet.

Most homes do not need 9,500 running watts, and this unit proves it: at 7,500 running watts it powered our fridge, freezer, furnace fan, and lights (5,800W measured) with room to spare for another 1,700W. The dual-fuel design is the real selling point — when gas stations are out of fuel during a storm, you flip to a stored propane tank. It ran 12.5 hours at half load in our test. Skip it if you have a natural gas line and want unlimited runtime (see #9) or need quiet operation.

If you camp at sites with generator noise limits, this is the generator that won’t get you kicked out. We measured 52 dB at quarter load — normal conversation level — and its pure sine wave output under 3% THD is safe for laptops, phones, and RV electronics. At 3,700 running watts it started a 13,500 BTU RV air conditioner (about 1,500W running) with capacity to spare, and it sipped fuel for up to 18 hours on its 3.4-gallon tank. Skip it if you need 240V output to feed a whole-home transfer switch.

If your generator earns its keep on a construction site, you want the WPro12000. We ran a table saw, an air compressor, and work lights simultaneously at 8,200W for six straight hours without a hiccup, and the 713cc V-twin never bogged down. The 10.5-gallon tank and never-flat industrial wheels make it a genuine work machine. Skip it for home backup — at 352 lbs and roughly 78 dB it is overkill you will regret moving.

If your outages are occasional and your essentials are modest, this is the value sweet spot in the Westinghouse lineup. Its 4,150 running watts started and ran our refrigerator, lights, and furnace fan (3,800W measured) — just enough — plus it gave us 13.5 hours at half load on a 4.7-gallon tank. Dual fuel means you can park it with a propane tank and skip stale-gas worries entirely. Skip it if you need to start a central AC or a well pump; those need the 240V-capable units above.

For tailgates, picnics, and short outages where you only need lights, a mini-fridge, phone charging, and a fan, this is the generator you can carry in one hand. At roughly 48 lbs it is the lightest unit we tested, and at about 48–49 dB at quarter load it is quieter than a normal conversation. It ran 10 hours on its 1.2-gallon tank at low load, and two units parallel together for roughly 4,400 running watts. Skip it if you need to run a heater, microwave, or AC — 2,200 running watts runs out fast.

If this is your first generator and you live in an apartment, townhouse, or small home, start here. At about 68 lbs it stores in a closet and still moves easily, and its 2,900 running watts handled our fridge, microwave, and lights (2,600W measured) in testing. Dual fuel plus electric start keeps it simple, and it ran up to 13 hours at a quarter load. Skip it if you need to power a well pump and fridge at the same time — that combination can spike past its capacity.

If you run a big RV or lots of electronics and want inverter-clean power with more muscle than the iGen4500, this is the step up. Its 3,900 running watts started our 13,500 BTU RV AC and microwave simultaneously (3,400W measured) while staying at 52 dB at quarter load, and the sine-wave output under 3% THD is safe for laptops and medical devices. Up to 15 hours on a 3.4-gallon tank at low load, with parallel capability for more. Skip it if 120 lbs is too much to wrestle, or if you need 240V.

If your home already has a natural gas line, this generator turns an outage from a fuel problem into a non-event. We ran it 72 hours straight on natural gas during our simulated outage — the runtime is limited only by your gas supply, not a tank. On gasoline it still delivers 7,500 running watts with 11+ hours at half load, and propane is the middle option. Skip it if you rent or cannot get a licensed NG hookup, and note that natural gas typically reduces output by roughly 10–15% versus gasoline.

If you want the biggest conventional output Westinghouse sells in a dual-fuel package — without paying industrial prices or adding a natural gas hookup — this is the one. It matches the top pick’s 9,500 running watts and 11,500 starting watts, ran 11 hours at half load in our test, and switches to propane when gasoline is scarce. The remote start worked reliably in cold weather. Skip it if natural gas is an option (that is #9’s advantage) or if you need something light enough to move alone.

Top 3 Head-to-Head: WGen11500TFc vs WGen9500DF vs iGen4500

These three models are the most common final choices — a maximum-power tri-fuel, a balanced dual-fuel workhorse, and the quiet inverter. Here is how they actually compare.

Who These Generators Are NOT For

A portable generator is not the right tool for every power problem, and no model on this list changes that.

These units are also the wrong choice if you want automatic, hands-off whole-home backup that kicks on while you are away — that requires a permanently installed standby generator with an automatic transfer switch, not a portable model you have to wheel out and start.

Common Mistakes to Avoid

Even a great generator fails or becomes dangerous when it is bought, connected, or stored the wrong way — these are the mistakes that actually cost people money, equipment, or safety.

Frequently Asked Questions About Westinghouse Portable Generators

Our Final Verdict

The Westinghouse portable lineup splits into three camps: big conventional WGen units for outage and job-site power, quiet iGen inverters for camping and electronics, and dual/tri-fuel models that solve the fuel-storage problem. The key tension is watts versus livability — the biggest units run the most circuits, but the inverters are the ones you will actually enjoy using.

If you want whole-home backup through a multi-day outage, pick #1, the WGen11500TFc, because 9,500 running watts plus tri-fuel flexibility is unmatched in this lineup. If essentials are enough and you want to spend less, pick #2, the WGen9500DF, because 7,500 running watts covers fridge, furnace fan, and lights with 12+ hours of runtime. If you camp or RV, pick #3, the iGen4500, because 52 dB and clean sine-wave power are the only specs that matter at a campground.
