As part of its ongoing Labor Day Sale event with up to 58% discounts, EcoFlow is now adding a four-day August EcoCredits Monthly Madness flash sale to the mix, with three featured power station units, a smart generator deal, and two limited-stock, members-only EcoCredits specials. This flash sale is providing folks with another chance at the 6,144Wh DELTA Pro Ultra Portable Power Station down at $4,099 shipped, beating out Amazon by $100. Down from its $5,799 full price directly, this unit has largely been available to score down at this same rate throughout 2026, which only comes beaten out by some short-term falls to $3,999 and $3,784, particularly during Prime Day in June. The deal here gives you $1,700 off its MSRP for the third-lowest price we have tracked directly from EcoFlow or Amazon this year. Head below to check out the other flash sale offers before they end Saturday night, August 30.
If you’re looking for one of EcoFlow’s most capable backup companions for trips, at-home emergencies, and far more, the DELTA Pro Ultra power station definitely sits among the top picks, right alongside the newer DELTA Pro Ultra X power station. It starts here at an already significant 6,144Wh LiFePO4 capacity, which can expand as high as 90kWh, while the 7,200W of maximum output ability can also expand with the capacity up to 21.6kW, and which can be integrated into your home system with a Smart Home Panel 2. You don’t need to worry about the elements’ effects on its operation, thanks to the IP54 dust-proof and splash-proof construction and its ability to withstand temperatures ranging from -4 to 113 degrees.
It shouldn’t come as any surprise that it also brings along plenty of recharging options, too. Those include an expandable solar panel input range of 5.6kW to 16.8kW, the standard AC outlet charging, as well as gas generator and EV pile connection options – plus, as I mentioned, pairing it with a Smart Home Panel 2 gives you access to your home grid, roof panels you may have installed, and allowing dual charging methods (AC + solar, for example).
