Expand your EcoFlow DELTA Pro setup with two expansion batteries at $2,699 in flash savings ($2,899 off), more

$2,899 off/$2,699

As part of its ongoing early Prime Day Sale through July 7, EcoFlow has launched the first of its scheduled flash sales, with two offers to upgrade your outdoor adventures. The first of these deals gives you two DELTA Pro Smart Extra Batteries for $2,699 shipped. This add-on bundle carries a $5,598 MSRP, but for the rest of the day you’ll benefit from the 52% markdown here to upgrade your DELTA Pro setup with $2,899 in savings. Considering that the lowest we’ve seen one battery go for was $1,399 during Black Friday and Christmas sales, this deal saves you $99 off buying two separately at those lowest rates, making this the best chance we have tracked to significantly expand your backup power support. It’s beating out Amazon by much more right now, where one unit is priced at $1,599, which comes in at $249.50 above the cost of each in this bundle.

If you’ve been wanting to expand your DELTA Pro setup beyond just the station, or further bolster things for greater backup power support inside or outside of the home, this DELTA Pro expansion battery bundle is certainly the best chance we’ve seen yet. Each of the batteries adds 3,600Wh to your overall capacity, giving you 10,800Wh should you currently only have the station, and helping to push you closer to its maximum 25kWh.

The second of these flash offers comes through the brand’s official Amazon storefront, giving you the new WAVE 3 Portable AC/Heater with an add-on battery and a free bag for the unit at $1,399 shipped, down from $2,299. This setup gives you mobile AC and heating for your tent, car, camper, or any other enclosed space, with the brand claiming it to “drop temperatures by 15 degrees in 15 minutes” or “warming a space by 17 degrees in 15 minutes.” There are plenty of smart controls via the app, like the new PetCare feature that automatically starts cooling when temperatures hit 77 degrees, among others.
