As part of its ongoing Spring Sale event on power stations, which is running parallel to Amazon’s ongoing Big Spring Sale, EcoFlow has launched the final 48-hour flash sale of March, which cuts up to 61% off the tags for two power stations, a DELTA Pro expansion battery, and a portable AC/heater. Among the two backup power solutions, this 48-hour window lets you jump on the extremely versatile EcoFlow DELTA Pro 3 4,096Wh Portable Power Station at $2,099 shipped, matching its current Amazon spring sale pricing. While we have seen the price spike up to its $3,699 MSRP a few times in 2026, it’s more often kept down between $2,299 and $3,066 most of the time in the new year, with today’s rate beaten out by falls to $1,999, as well as a one-time drop to its latest $1,899 low back in mid-January. For the next two days, you can grab one with a 43% markdown that cuts $1,600 off the tag for the third-lowest price we have tracked (and the second-lowest recurring discount). Of course, if you want to save a bit more for a smaller unit, the 3,072Wh DELTA 3 Ultra Portable Power Station is down at its second-lowest $1,099 rate, beating out Amazon by $100. Head below for the other flash offers while they’re still live.
One of my absolute favorite options from EcoFlow is the highly versatile DELTA Pro 3 power station, particularly its 26 options for recharging that far exceed the usual 4 to 5 options we see on the newest models (seven single-source, 18 combination sources). You’ll also be getting a much larger 4,096Wh starting LiFePO4 capacity that can scale as high as 48,000Wh with expansion batteries. There are 12 output ports for all your connection needs (with one being a TT-30R port to cover RV backup), through which it can produce up to 4,000W of power, which also increases up to 12,000W of power when fully expanded.
Of course, you can save $1,000 by going with EcoFlow’s DELTA 3 Ultra power station, which still brings along a robust 3,072Wh LiFePO4 battery. This model is specifically designed not to expand, while its DELTA 3 Ultra Plus variant is available for scaling backup support. Still, it’s a highly capable option with 10 ports (5x AC, 3x USB-C, 1x USB-A, 1x car port), up to 3,600W of steady output (and up to 7,200W surging), and quieter 25dB operation. This model does offer the more average array of four recharging methods: AC charging, gas generator charging, a max 800W solar charging input, and car port charging while you drive (with faster speeds available through an alternator charger).
