Amazon's fall Prime sale ends just before midnight Pacific tonight, so if a home backup battery has been sitting in your cart, you're running out of time. Before you buy, Amazon's own AI shopping tool can tell you whether the discount is as deep as the tag says.
Prime Big Deal Days opened Tuesday and runs for two days. Amazon (AMZN) says most of its deals are at its "lowest prices of the year so far". Electrek rounded up the clean energy deals, and the big power stations got some of the largest dollar cuts. We compared those sale prices with the lowest earlier prices reported for each model:
| Power station | Sale price | Lowest earlier price |
|---|---|---|
| Anker SOLIX F3800 | $1,710 | $1,799, a flash sale low noted by 9to5Toys in March 2026 |
| Jackery HomePower 3600 Pro Max | $1,664 | $1,699, on Amazon during July's Prime Day |
| EcoFlow DELTA 3 Plus | $1,438 | Not confirmed. Electrek lists this one as a 3,072Wh setup, and we couldn't match it to a tracked listing |
The sale prices come from Electrek's roundup published October 6, and we checked the price history on October 7. Amazon prices can change by the hour, so treat them as a snapshot. On those numbers, the Anker and Jackery are both below anything reported before. Jackery's usual price these days is $2,099, according to 9to5Toys.
The same roundup also has cheaper picks, including a smaller Bluetti station, Segway e-scooters and robot mowers, and Greenworks yard tools.
Read an "up to" tag as the best case. Electrek attaches the up to 58% figure to EcoFlow's whole sale, which starts at $279, and not to the DELTA 3 Plus itself. Our advice: the deepest cut in a sale like this usually lands on one version of a product and is measured from a list price it rarely sells at. Amazon's answer is Alexa for Shopping, which the company says shows "up to 365 days of pricing insights," so you can see whether today's price really is a low.
The tool can also watch for a target price and ping you when an item drops to it, or simply buy it for you. Amazon's sample prompt is about as plain as it gets: "Are any items on my list on deal right now?" Auto-buy makes sense for a leaf blower. For a battery that costs more than most laptops, you'll probably want to look at the order yourself before it goes through.
Amazon bills this sale as the start of holiday shopping, so these power stations will face their next price check soon. If you're not buying tonight, set a price alert on the exact model and version you want before you close the tab. That way you'll know right away if a holiday sale beats tonight's price.
