As part of its ongoing Mother’s Day Sale, EcoFlow has launched a 48-hour flash sale with up to 59% savings on three units – two being solar bundles and one being a portable electric cooler bundle. Among the two solar packages, things start with the DELTA 3 Max Portable Power Station with a 220W solar panel down at $999 shipped, matching the price we’re seeing over at Amazon. While you may see it tagged with a $2,148 MSRP, it hasn’t really climbed higher than $1,249 in 2026, with discounts usually keeping the costs lower between $1,099 and $1,049, though there have been periods where things dipped to $999, which is beaten out only by the $949 low we last saw during Black Friday. For two days, you can take advantage of this $250 markdown off the going rate (and $1,149 off the MSRP) for the second-lowest price we have tracked behind Black Friday pricing. Head below to check out the full lineup of flash deals while they last.
Among the DELTA 3 series power stations, EcoFlow’s DELTA 3 Max sits in the middle of the pack with it’s 2,048Wh LiFePO4 battery capacity and 2,400W of steady power output (surging to a max 4,800W). Like the other variants in the series, you can use extra batteries from the DELTA 3, DELTA Pro 3, DELTA 2 Max, or DELTA 2 models in order to expand its initial capacity all the way up to 10,240Wh.
It comes with nine connection ports for its power output (4x ACs, 3x USB-Cs, 1x USB-A, and a car port), as well as four primary recharging methods. You can plug it into a standard AC outlet, connect up to 500W of solar panel input, use your car’s auxiliary port as you drive, or upgrade for faster on-the-go speeds with an alternator charger.
