Key takeaways
- Pro: Fuel flexibility protects you during supply disruptions
- Pro: Wattage covers most single-family backup scenarios
- Con: Not a standby system; you still need to start it manually and run cords or install a transfer switch
A buyer searching for the best deal on generators usually wants one of three things: reliable backup power for a home during outages, a compact unit for a job site or camping trip, or an accessory that protects an existing investment. The market conflates all of these under the same keyword, and the price spread runs from thirty dollars to just under a thousand, which makes comparison feel paralyzing.
What separates a good purchase from a regrettable one here is clarity about what you actually need. A 12500-watt dual-fuel standby unit solves a completely different problem than a 300-watt solar generator or a canvas cover, and conflating them leads to overspending on the wrong category. This roundup compares eight products people encounter when hunting for deals, sorted from highest output to lowest price, so you can identify your lane quickly.

How We Picked
We compared published specifications, listed prices, and recurring themes in owner feedback across all eight products. Four criteria drove our ranking: whether the product solves a defined problem at its stated price point, build quality and weather resistance as described by the manufacturer and confirmed in reviews, output adequacy for the intended use case (power generators rated by wattage, ozone units by milligrams, covers by compatible generator size), and the presence of meaningful limitations that affect long-term value. We flagged any product whose listing name misrepresents its category relative to the search keyword.
The 8 Best Deal On Generators in 2026
Westinghouse 12500 Watt Dual Fuel Home Backup Portable Generator
This is the unit most people actually mean when they type “best deal on generators” into a search bar. At 12500 watts it handles a household’s essential circuits — refrigerator, furnace blower, well pump, a few lights — without tripping. Dual fuel means you can run on propane when gasoline is scarce or unavailable, and the remote electric start removes the pull-cord struggle in cold weather. Transfer switch readiness lets an electrician wire it into your home’s panel safely.
- Pro: Fuel flexibility protects you during supply disruptions
- Pro: Wattage covers most single-family backup scenarios
- Con: Not a standby system; you still need to start it manually and run cords or install a transfer switch
Consider another product if you need true automatic switchover during outages or your budget caps out below this price. Owners note the unit is heavy to move without assistance, so plan a semi-permanent placement location.
Jackery Solar Generator 300 and 40W Solar Panel
At 292Wh capacity and 300W AC output, this is a battery bank that recharges from a bundled solar panel, not a combustion generator. It powers a phone, a small CPAP machine for one or two nights, a laptop, or a 12V fridge for a weekend trip. The solar panel lets you top off in sunlight without carrying fuel cans.
- Pro: Silent, zero-emission operation suits apartments and campsites
- Pro: Solar panel included removes a separate accessory purchase
- Con: 300W output cannot run anything with a motor or heating element at full draw
Skip this if you need to run a microwave, space heater, or power tool. It is a device charger first and a “generator” only in the loosest marketing sense. At $339 the value depends on whether you will actually use the solar panel or plug into wall outlets most of the time.
Big Generator
At $30.51 this product is priced far below every other entry on this list, and that alone should raise questions about what you are getting. The name is generic, and the listing provides minimal specification detail beyond the price point. In the portable power landscape, sub-$50 generators are typically single-cylinder units rated well below 1000 watts, suitable for a light bulb and maybe a small radio.
- Pro: Lowest entry price on this list
- Pro: Compact form factor for storage in a drawer or small space
- Con: Published specs are sparse, making it difficult to confirm output, fuel type, or runtime before purchase
This is a reasonable impulse buy for a bug-out drawer or a child’s science project, but do not plan a household around it. Skip entirely if you need anything beyond a single small load.
Ozone Generator 48,000mg
Despite the name, this unit produces zero electrical power. It is an ozone machine rated at 48,000 milligrams per hour of O3 output, designed to eliminate odors from smoke damage, pet accidents, mold spores, and persistent chemical smells in enclosed spaces. It runs on standard household current and is sold under the keyword “generator” purely because of the shared English word.
- Pro: High output rating treats large or heavily affected rooms in a single session
- Pro: Chemical-free approach to odor removal compared to masking sprays
- Con: Ozone is harmful to lungs and plants; the room must be vacated and ventilated afterward
Purchase this only if you have an odor problem and no one (including pets) will occupy the space during treatment. Do not buy it expecting it to power anything.
AI Image Generator
Another keyword match that is not a power device. This product generates digital images using artificial intelligence, with no wattage, no fuel, and no physical form factor. The price is listed as n/a, suggesting a free tier, subscription model, or unpriced marketplace listing. It appears in this roundup solely because the word “generator” places it alongside power equipment in search results.
- Pro: Useful for creating concept art, marketing visuals, or personal projects without design skills
- Pro: Zero operating cost beyond internet access if a free tier exists
- Con: Cannot be evaluated on the same specs as physical generators; no output, runtime, or durability metric applies
Skip this entire listing if you are shopping for equipment that produces electricity. It solves a creative problem, not an energy one.
Westinghouse Outdoor Power Equipment WGen Generator Cover
At $17.30 this is a fabric cover sized for portable generators up to 9500 rated watts. It protects the unit from rain, UV degradation, dust, and bird droppings while stored outdoors. If you own a mid-size generator and leave it in a garage, carport, or shed, a cover measurably extends its service life by keeping the engine components free of moisture.
- Pro: Fits the largest range of common home-backup units up to 9500 watts
- Pro: Brand-specific design ensures a snug fit on Westinghouse chassis without improvised strapping
- Con: Not compatible with generators above 9500 watts, including the Westinghouse 12500W reviewed above
This is a worthwhile accessory if you own a generator in its size range. If your unit exceeds 9500 watts, look at the Champion cover instead.
Champion Power Equipment Weather-Resistant Storage Cover
Priced at $19.99, this cover accommodates portable generators rated between 4800 and 11,500 watts, making it the broadest single-size option in the accessory category here. It suits most whole-home backup units, including the Westinghouse 12500W at the top of this list, since its upper limit is 11,500 watts — though buyers should verify their specific model’s dimensions before assuming compatibility at the extreme end.
- Pro: Wide wattage range reduces the chance of a sizing mistake
- Pro: Weather-resistant construction handles sustained outdoor exposure
- Con: At 160 cents more than the WEN alternative, the price premium needs justification from fit quality
Buy this if you own a larger unit and want one cover that does not leave critical dimensions uncovered. Measure your generator before purchasing regardless of the stated range.
WEN 56310iC Universal Weatherproof Inverter Generator Cover, Large
The least expensive cover at $15.99, this WEN option is marketed as universal-fit and weatherproof. Inverter generators tend to be enclosed in plastic housings rather than exposed metal frames, and this cover’s “large” designation targets those chassis shapes. If you own an inverter unit in the mid-size range, this is the most cost-effective protection you can add.
- Pro: Lowest price of the three covers in this roundup
- Pro: Universal fit claims accommodate multiple inverter brands, not just WEN
- Con: “Universal” often means the fit is loose on units that differ from the original WEN 56310iC shape, which can let moisture in at the edges
Good enough for a garage or covered patio where rain is indirect. Skip if your generator sits fully exposed to driving rain, where a snug brand-specific cover matters more.
Buying Guide
Match Output to Your Actual Load
Wattage is the single number that determines whether a generator solves your problem. Add up the starting wattage of every appliance you intend to run — motors like refrigerators and pumps draw two to three times their running watts at startup — and buy a unit whose rated output exceeds that total with headroom. The Westinghouse 12500W covers a typical household’s essentials; the Jackery 300W unit covers electronics only. Buying undersized leads to overloaded circuits and damaged equipment.
Dual Fuel vs. Single Fuel
Gasoline-only generators are cheaper upfront but depend on a fuel supply that may be disrupted during the same event that knocks out your power. Dual-fuel units let you switch to propane, which stores indefinitely and is more readily available after storms. The trade-off is a higher purchase price and slightly lower peak output on propane. For home backup, dual fuel is the more resilient choice.
Cover Sizing and Material
A generator cover is only useful if it fits snugly enough to block wind-driven rain and is made from material that resists UV degradation and mold. Check the upper wattage limit against your unit’s rating and confirm the physical dimensions. Brand-specific covers generally fit better; universal covers work adequately when the generator shape is common. In 2026, even budget covers use bonded waterproof layers, so the difference between a $16 and a $20 option is usually fit precision rather than material quality.
Our Verdict
The Westinghouse 12500 Watt Dual Fuel is the strongest value in this roundup for anyone whose actual need is home backup power. It solves the stated problem completely, the dual-fuel system adds resilience at no extra accessory cost, and $999 positions it well below permanently installed standby systems that run several thousand dollars more. For a budget-conscious buyer who only needs to protect an existing generator from the elements, the WEN cover at $15.99 is the clear pick. One condition shifts the verdict: if your situation is light-power camping or emergency device charging with no fuel logistics, the Jackery Solar Generator 300 wins on portability and silence despite its limited output.
FAQ
Are ozone generators and AI generators the same as power generators?
No. Ozone generators produce a gas for chemical treatment, and AI image generators produce digital content. Neither creates electrical power. They share the word “generator” in their product names, which is why they appear in search results alongside equipment that does.
How many watts do I need for basic home backup?
Most households need between 5000 and 8000 watts to run a refrigerator, a furnace blower, a well pump, and lighting. The Westinghouse 12500W unit covers that range with significant headroom, meaning you can add a window AC or microwave without hitting the ceiling.
Can a solar generator replace a gas generator?
Only for small loads and short durations. A 292Wh battery like the Jackery 300 stores enough energy for a phone, laptop, or small CPAP for a few hours. It cannot run high-draw appliances or sustain output through a multi-day outage without sunlight to recharge.
Is a generator cover necessary if the unit is stored in a garage?
Less critical but still beneficial. Garages accumulate dust, and some allow humidity and small pests. A cover slows cosmetic degradation and keeps debris out of air intakes, which can extend service intervals between cleanings.
