Yes, on the battery side. Jackery and EcoFlow are both running their fall sales into early October, with the Jackery HomePower 1000 Plus v2 at $679 against $759, the EcoFlow DELTA 2 Max at $1,029 against $1,299 and the DELTA Pro 3 at $2,799 against $3,699. Gas generators are holding price, with the Sportsman 4,000-watt at $279.99 at Tractor Supply. The one thing you can't buy at any price is a generator during the outage itself.
Before anything about price, the rule that actually matters: a portable generator has to run at least 20 feet from the house with the exhaust pointed away from windows, doors and vents. Not in the garage with the door open, not on a covered porch, not under a deck. Carbon monoxide from generators kills people during every major outage, and it does it quietly. Newer units carry a CO shutoff that kills the engine when levels build nearby, and the ones certified to UL 2201-2023 also produce less CO to begin with. If you're buying now rather than in a panic, buy one of those.
Early Columbus Day Generator Deals
The discounts in this category are on the battery side, and both battery makers are running dated fall sales that end in the first week of October. These are the live markdowns at each, checked against the product page.
Jackery HomePower 1000 Plus v2
- 1,024Wh
- 1,800W output
- Expandable to 11kWh
The starting size for indoor backup: 1,024Wh runs a fridge, a router, lights and phones through a night, and 1,800W of output starts the fridge compressor without complaint. Plug in extra batteries and it grows to 11kWh, so it doesn't have to be the last power station you buy.
The v2 is the current generation, not the one being cleared, so the 10% is a sale on the model that just launched. The 30 day price match on top means an October Prime Day cut would come back to you anyway.
$679$75911% off
Jackery Solar Generator HomePower 3000
- 3,072Wh
- 3,600W output
- Panel included
The HomePower 3000 station sold with its solar panel, which is the configuration that turns a finite battery into a multi-day outage plan. At 3,600W it runs a well pump or a window air conditioner alongside the fridge. The version with the 500 X bifacial panel is $1,899 against $2,329 in the same sale.
Read the panel wattage, not the station size. A few hundred watts of panel takes more than a full clear day to refill 3,072Wh from empty, so treat the solar as a top-up between grid days rather than a replacement for the grid.
$1,799$2,14916% off
Jackery HomePower 3600 Pro Max
- 3,584Wh
- 4,000W output
- 10+ year lifespan
The top of the portable line, with 4,000W of continuous output, which is the number that lets it start a well pump, a sump pump and a fridge at the same time rather than one after another. Jackery rates it for 10 or more years of use.
The HomePower 3600 Plus is the same capacity with 3,600W of output at $1,709 in the same sale. The $90 gap buys 400 more watts of headroom, which only matters if you plan to run a 240V or a large motor load.
$1,799$2,09914% off
- 1,024Wh
- 1,800W output
- Expandable to 5kWh
The direct rival to the Jackery 1000 Plus v2, with the same 1,024Wh and 1,800W of output, 2,200W with X-Boost for a resistive load like a kettle. It grows to 5kWh with EcoFlow's extra batteries and carries a five year warranty.
Five ways to refill it, per the listing: the wall, solar, an 800W alternator charger off a running car, EcoFlow's dual fuel smart generator, or several of those at once. The car option is the one that matters on day three of an outage.
$669$79916% off
- 2,048Wh
- 2,400W output
- Earlier generation
Twice the battery of the DELTA 3 Plus with 2,400W of output, which covers a fridge, a freezer and a space heater together. This is the earlier DELTA generation, which is why it carries a deeper cut than the newer units around it.
Two thousand watt-hours is the size where one unit covers a whole evening of fridge, freezer and a space heater. Check the extra battery price before you buy, because adding capacity later is where the real cost sits.
$1,029$1,29921% off
- 4,096Wh
- 4,000W output
- 120V and 240V
The one on this page that can take a transfer switch seriously. It puts out 4,000W with both 120V and 240V, so it runs a well pump or a dryer, and the listing rates it as expandable to 48kWh with extra batteries. The 24% cut is the largest dollar saving on either sale page at $900.
A unit this size is a home electrical project, not a purchase. Budget for the transfer switch and the electrician, because plugging it into a wall outlet to feed the house is the backfeeding mistake covered lower on this page.
$2,799$3,69924% off
Prices come from each seller at the time this page was last refreshed. Jackery labels its sale through October 3 and EcoFlow through October 5, so check the current number on the product page before you buy.
Top 3 Generator Deals on Amazon
The three generator listings with the steepest discounts on Amazon, ranked by markdown. Sizing matters more than brand here. Add up the running watts of what you actually need during an outage, then leave headroom for the biggest starting surge on the list, because motors draw two to three times their running load for a second or two when they kick in. A fridge is roughly 700 running and 2,200 starting, and a half-horsepower sump pump about 1,000 running and 2,100 starting.
When Generators Actually Go On Sale
Generator pricing runs on weather and on fear, which makes the calendar unusually predictable in both directions.
| When | What to expect |
|---|---|
| Late winter and early spring | The annual low. Storm season is over, warehouses are full, and nobody is thinking about outages. If you can plan a generator purchase months ahead, this is the window to plan it for. |
| Black Friday and Cyber Monday | Deep and reliable, particularly on power stations and solar kits, which follow electronics pricing rather than hardware pricing. |
| Early Columbus Day, through the first week of October | Strong on batteries, flat on engines. Jackery and EcoFlow both run a fall sale timed to the October Prime Day, with 10% to 24% off the current power station lines, and both end in the first days of October. Gas generators hold price. Buying now also means you own it before the peak of hurricane season rather than during it. |
| Whenever a brand refreshes a model | The outgoing unit drops hard and a generator is a simple machine, so a one-generation-old engine isn't meaningfully worse. Check whether the older model has a CO shutoff before you save the money. |
| Prime Day, July and October | Good on portable power stations and solar panels, thin on gas units. The battery side of this category is priced like consumer electronics. |
| The week a storm is forecast | The worst possible time, every time. Prices firm up, stock disappears, and you end up buying whatever is left rather than what you needed. This is the entire argument for buying one in advance. |
What Actually Counts as a Good Generator Deal
Judge these by watts per dollar and by what fuels they take, because those are what you'll live with.
- 4,000-watt portable under $300. Enough for a fridge, a sump pump, some lights and a few outlets. Tractor Supply has the Sportsman 4,000/3,500-watt at $279.99, which is the right shape for this band, and the Westinghouse 4,650-watt with a CO sensor at $399.99 is the one to step up to.
- 2,000 to 2,500-watt inverter under $500. The quiet, fuel-efficient, clean-power option for camping, tailgating and running electronics. Not a whole-house solution and not trying to be.
- Dual fuel with a CO sensor under $600. Tractor Supply has the DuroMax 13,000-watt dual fuel with a CO alert at $999.99, which is over the band but the cheapest dual fuel with the sensor on its shelf. Dual fuel means propane when gasoline is gone, which during an actual outage is the feature that matters.
- 9,000 to 12,500-watt home backup under $1,300. Enough to run most of a house through a transfer switch. Tractor Supply has the DuroMax 13,000-watt dual fuel at $999.99 and the Westinghouse 14,500-watt tri fuel with a CO sensor at $1,499.99, which are the benchmarks to beat.
- 1,000Wh power station under $700. Jackery has the HomePower 1000 Plus v2 at $679 against $759 and EcoFlow has the DELTA 3 Plus at $669 against $799, both 1,024Wh and 1,800W. Silent, indoor-safe, and the only option that runs in an apartment.
Where to Shop Generators
Worth checking beyond Amazon, because the battery makers run their own sales on their own calendars, and the farm store is the clearest place to see which gas models carry a CO shutoff.
How to Pick the Right Generator
Size it on starting watts, not running watts. List what you actually need, add up the running load, then add the single largest starting surge on the list rather than all of them. A fridge is about 700 running and 2,200 starting, a half-horsepower sump pump about 1,000 and 2,100, a 10,000 BTU window unit about 1,200 and 1,800. Getting this wrong is why a generator that looked big enough trips the moment the compressor kicks in.
Buy the CO shutoff. Models built to PGMA G300-2023 or UL 2201-2023 shut the engine down when carbon monoxide builds nearby, and the UL 2201 units emit less to begin with. It costs very little on top of a modern generator and it protects against the exact mistake people make at 2am in a storm.
Take dual fuel seriously. Gas stations can't pump without power, so the fuel you planned on is the fuel that runs out first in a long outage. Propane keeps indefinitely, sits safely in the garage and starts a cold engine more reliably. Tri fuel adds a natural gas line, which if you have one never runs out at all.
Decide between an engine and a battery honestly. A power station is silent, indoor-safe and maintenance-free, and it runs a fridge and your devices rather than your house. A gas generator runs the house and has to live 20 feet away in the weather. Plenty of people should own the battery, not the engine, and the ones in apartments have no choice.
Plan the connection before you need it. Running extension cords through a window is the normal way to use a portable generator, and it's fine. What isn't fine is backfeeding through a dryer outlet, which is illegal, kills utility linemen and can burn the house down. If you want the generator to run circuits, an electrician and a transfer switch is the only correct answer.
Generator Sale FAQ
The Bottom Line
Buy the generator before you need it, because the week a storm is forecast is the one moment in the year when nothing is discounted and nothing is in stock. Size it on the largest starting surge rather than the running total, take dual fuel if you can since gas pumps stop working in exactly the outage you bought it for, and pay the small premium for a model with a CO shutoff. Then run it 20 feet from the house with the exhaust pointed away, every single time. The early Columbus Day window is the battery makers' moment, with Jackery at 10% to 16% off the HomePower line through October 3 and EcoFlow at 16% to 24% off the DELTA line through October 5, while the gas units at Tractor Supply hold list. If a power station is the right answer for your house, this is a reasonable moment to stop putting it off.
