EcoFlow 48-hour flash sale returns 3,072Wh DELTA 3 Ultra Plus power station to $1,399 low, more from $1,099

61% off/$1,099+

As part of the extended Earth Day Mega Sale, EcoFlow has launched a 48-hour flash sale period with up to 61% savings on two power station units, as well as some expansion battery and home backup bundles. One notable return during this window is the EcoFlow DELTA 3 Ultra Plus Portable Power Station at $1,399 shipped, beating out its Amazon pricing by $50. Though it has occasionally spiked back to its $2,899 full price, we’ve mostly seen this model staying at $1,449 since February, which happens to be the second-best price we have spotted in its history. Now, though, during these 48 hours, you’ll be getting $50 additional savings (and $1,500 total savings) that drops things back to the all-time lowest price we have tracked since it last appeared in January. Head below to learn more and browse the three other flash offers while they’re still around.

EcoFlow’s DELTA 3 Ultra Plus power station stands at the top of the DELTA 3 series hill since their launch back in 2025, with a 3,072Wh starting LiFePO4 capacity that you can invest in to expand as high as 11kWh – and the best part is it can utilize batteries from several of its counterparts rather than being stuck to a single model. There are 11 port options to connect devices/appliances (5x AC, 3x USB-C, 1x USB-A, 1x DC, and a car port), with those options able to provide up to 3,600W of steady output (boosted to 4,600W through in-app activation), while having the surge potential to reach a max 7,200W output.

You’ll have six primary means to top off the station’s battery, making it as versatile here as the expansion battery options to increase its capacity. There’s standard AC outlet charging, gas generator charging, car port charging – which hits greater speeds through an alternator charger – and up to 1,600W of solar panel input charging. From there, you have two options for dual-source charging, using either a gas generator and solar together, or an alternator charger and solar together.
