As part of its ongoing EcoCredits Monthly Madness Sale that is only continuing through tomorrow night, EcoFlow has also launched a 48-hour flash sale that is closing out the event with up to 62% discounts on four offers. Right alongside the return of the DELTA 3 Max Portable Power Station at its second-lowest $749 rate (beating Amazon by $50), this two-day window is also offering the more advanced DELTA 3 Ultra Portable Power Station at $1,299 shipped, which matches its Amazon pricing. While this model carries a $2,499 MSRP, we’ve been seeing it keep between $1,599 and $1,299 in 2026 so far, with this short-term event providing $300 savings off the highest price we have seen in 2026 (and $1,200 savings off the MSRP). Head below to learn more about these stations and browse the other flash sale offers while they’re still around.
While both the stations included in this flash sale are members of the latest DELTA 3 series, EcoFlow’s DELTA 3 Ultra power station comes as one of the two largest models with a 3,072Wh LiFePO4 capacity, but if you want expansive functionality, you’ll have to go with the DELTA 3 Ultra Plus model. It operates at a quieter 25dB level, delivering up to 3,600W of steady power (and surging as high as 7,200W) through its 10 output ports: five ACs, three USB-Cs, one USB-A, and a car port. There are four primary recharging methods here: standard AC charging, gas generator charging, up to 800W of solar charging, or on-the-move car port charging.
On the lower end of the power station offers is the return of EcoFlow’s DELTA 3 Max station at its second-lowest price, which has been a consistent offer across multiple flash sale events. It’s a highly capable mid-tier option with a 2,048Wh LiFePO4 capacity that can expand up to 10,240Wh using smart extra batteries for the DELTA 3, DELTA Pro 3, DELTA 2 Max, or DELTA 2 stations. It brings along a 2,400W steady output (and 4,800W surging) through nine ports: four ACs, three USB-Cs, one USB-A, and a car port. It offers the same four recharging options, as the above unit, though its solar input maximum sits lower at 500W.
