Save up to 56% on EcoFlow DELTA 2 and 3 Pro expansion batteries or a home hub starting from a $349 low for 48 hours

56% off/From $349

As part of its soon-to-end extended Prime Day Sale, EcoFlow has launched a 48-hour flash sale on three different units to either expand or upgrade your backup support, with prices starting lowest on the DELTA 2 Smart Extra Battery for $349 shipped, which beats out Amazon’s pricing by $60. This add-on unit normally carries a $799 MSRP direct from the brand, though it can often be found down around $599 on average, with discounts having usually dropped the costs further between $449 and $409, save for the one-time fall to this rate we spotted during the 2-day Prime event last week. Now, EcoFlow is bringing that low price back for the remaining days of its extended promotions, giving you a second-ever opportunity at $250 off its going rate ($450 off the MSRP) for the lowest price we have tracked. Head below for more on this and the other two units in this flash sale.

With EcoFlow’s DELTA 2 smart extra battery, you’ll be getting a more ample support solution from your legacy station, with it adding an additional 1,024Wh to your setup’s capacity, maxing out at 3,072Wh (station and two batteries). It’s a simple plug-and-play option to bolster your legacy station for greater (and longer) backup support, and comes rated for 10 years with its LiFePO4 battery cells. It comes with the same in-app smart controls as the station, for when you may choose to use it separately, as well as a 5-year warranty.

EcoFlow’s final extended Prime flash sale offers:

• DELTA 2 Smart Extra Battery (1,024Wh): $349 (Reg. $799)
• Two DELTA Pro 3 Smart Extra Batteries (4,096Wh each): $3,099 (Reg. $5,198)
• Smart Home Panel 2: $1,399 (Reg. $1,899)

You have through October 15 to take advantage of EcoFlow’s extended Prime Day deals seeing up to 65% discounts, which start from $169. The brand has also given us some new releases recently, like the DELTA 3 Max and Ultra power stations still benefitting from up to $2,000 launch savings, as well as FREE gear, all starting from $759. Likewise, the brand just launched its super early-bird promotion to score $1,000 off its upcoming DELTA Pro Ultra X whole-home power station that can be expanded up to a monstrous 180kWh capacity. You’ll find some other ongoing power station sales, as well as savings on EVs, lawn care solutions, and more – all collected into our Post-Prime Day Green Deals hub, while this week’s latest backup power savings can be found in our new power stations hub.
