As part of EcoFlow’s latest Home Preparedness Month Sale, which can benefit from using the bonus savings code EFPDFAFF at checkout, the brand is also offering four 48-hour flash sale units. One of the biggest deals in this flash window gives you 2x 3,072Wh DELTA 3 Ultra Portable Power Stations for $2,598 shipped, with the final $200 savings cut when placed in your cart and cannot stack with the above code, beating out Amazon’s pricing by $1,800. While the bundle may carry a $4,998 MSRP, the standalone DELTA 3 Ultra has only gone as high as $1,999 to $2,199 – meaning you would get two for as much as $3,998 to $4,398 in that case. However, the bundle here gives you these stations at $1,299 each, which is the far more common price we’ve seen for a single unit this year, though since August the solo station has been sitting higher at $1,399 (which is where the single unit is priced in this sale). This is a solid $1,800 savings that puts things at the third-lowest price we have tracked, beaten out by Prime Day’s short-term fall to $1,199 in June, as well as an even shorter-lasting Lightning Deal to $1,104 back in early March. Head below to see the full flash sale lineup.
This bundle for the two DELTA 3 Ultra power stations is handy for folks who need to split power supplies during trips, emergencies, and more, with each bring along 3,072Wh LiFePO4 batteries (6,144Wh combined). If you want the option to expand the capacities, you’ll need to instead go with the DELTA 3 Ultra Plus variant (which the bonus savings code works on).
Each DELTA 3 Ultra sports 10 output port options (5x AC, 3x USB-C, 1x USB-A, and car port) and can deliver up to 3,600W of steady power and surge as high as 7,200W. It has four main recharging methods, starting with the usual AC outlet charging that can reach 80% capacity in around 1.48 hours, which matches the rate from a gas generator, too. From there, you can connect up to 800W of solar panel input for 80% capacity in up to 3.37 hours, plug into a vehicle auxiliary port, or get faster on-the-go charging from the brand’s alternator chargers.
***Note: As I mentioned, the bonus savings code does not stack with these flash savings, but if you are shopping from the overall sale lineup here, be sure to use EFPDFAFF at checkout to guarantee you’re getting the best deal.
