As part of EcoFlow’s ongoing Disaster Winter Storm Sale that is continuing many of the previous December holiday savings, with some notable price drops and new lows, you can find the DELTA 3 Ultra Plus Portable Power Station down at $1,399 shipped, after an additional $100 is taken off automatically in your cart and can’t be stacked with the sale’s extra savings code, beating its Amazon pricing by $100. This newer unit carries a $2,899 MSRP since hitting the market at the end of September, but has been spending a considerable amount of time down at $1,499, with occasional spikes up to its full price and one-time falls lower to $1,424 during Black Friday/Cyber Monday and the $1,359 low from a New Year flash sale. With the bonus savings you’re scoring the next-best deal we have tracked behind that flash offer, cutting $1,500 off the full rate for the second-lowest price we have tracked. Head below to also browse the roundup of DELTA 3 series power station deals during this event.
Among EcoFlow’s latest DELTA 3 series, the DELTA 3 Ultra Plus power station stands at the top of the hill and boasts an impressive starting 3,072Wh LiFePO4 battery capacity that can cover camping/travelling needs, at-home emergencies, and more. What’s even better is the fact that you can scale its capacity up as high as 11kWh using various batteries from the series, making it a more versatile modular system than usual. There are 11 output ports to connect devices/appliances (5x AC, 3x USB-C, 1x USB-A, 1x DC, and a car port), with the station producing up to 3,600W of power that can climb to 4,600W with X-Boost activated or surge higher up to 7,200W.
Following the trend of expanded charging methods we’ve seen from many of the newest releases across 2025, this station boasts six ways to recharge its battery, starting with the typical AC charging that can return it to 80% capacity in up to 89 minutes. You also have options for a gas generator, one of the brand’s alternator chargers, or up to 1,600W of maximum solar input. That’s not all, as you have dual charging options for either solar and a generator or solar and an alternator charger.
