EcoFlow’s expanded 5,120Wh DELTA 3 Ultra Plus power station drops to $1,999 2026 low in flash sale, more from $549

As part of the current EcoFlow Mother’s Day Sale that is approaching its end date, the brand has included another 48-hour flash sale window into the event for up to 61% discounts across four units. While two options are add-on accessories (solar panel or extra battery), and the third is the brand’s portable AC/heater, we are seeing a notable price drop on the DELTA 3 Ultra Plus Portable Power Station with a DELTA 3 Plus Extra Battery for $1,999 shipped, beating out its Amazon pricing by $200. Down from $4,298, we’ve been seeing this bundle holding out at $2,199 since April at Amazon, but this flash sale is giving you two days to jump on an additional $200 savings. It comes as a 53% markdown off the going rate for $2,299 of total savings off the full MSRP, landing it at the best price we have tracked since Black Friday, which was when we last saw the $1,899 low appear.

The DELTA 3 Ultra Plus station from EcoFlow sits at the top of the new DELTA 3 series in terms of capacity and output power. With this bundle, the normally 3,072Wh starting capacity is instead boosted to 5,120Wh, and can further expand all the way up to 11kWh with more equipment added on. That expansion, as you may have guessed from the current bundle, can happen via multiple batteries for other power stations in the series, making it a much more versatile solution. It steadily dishes out up to 3,600W of regular power, which can be boosted to 4,600W through its in-app smart controls, while also surging as high as 7,200W – all this through 11 output port options: 5x AC, 3x USB-C, 1x USB-A, 1x DC, and a car port.

And as its expandability brings far more options that we usually see on a power station, so too is its recharging options more versatile. There’s the standard AC charging from any standard outlet, as well as connections for a gas generator, one of the brand’s alternator chargers, or the standard car auxiliary port. You can also utilize up to a maximum 1,600W of solar input, or use one of two dual-source methods: solar with a generator, or solar with an alternator charger.
