EcoFlow’s Earth Day Sale may have ended, but the brand has shifted to a similar (though smaller) Power Your Outdoor Adventures Sale with up to 64% discounts on power stations and accessories. You can find a nice array of power solutions, with one of the units at the lower end of costs being the DELTA 3 Plus Portable Power Station down at $599 shipped, beating out its Amazon storefront pricing by $50. It’s down from a $799 full price here, with the discounts we’ve seen in 2026 having mostly kept things above $649, though there have been two previous falls to $599 during March’s Big Spring Sale and the brand’s previous Earth Day sale, only beaten out by an exclusive deal in 2025 for $549. Now, during the weeklong window here, you’re getting the continued chance to score it with a $200 markdown to the lowest non-exclusive price we have tracked. Head below to browse the full lineup of deals while this sale event lasts.
The EcoFlow DELTA 3 Plus power station is a smaller but still fully capable unit with plenty of power to cover your devices and essentials while away or at home. It houses a 1,024Wh LiFePO4 battery setup that dishes out up to 1,800W of steady power (2,200W with X-Boost activated and surging to a max 3,600W) through 13 ports (6x ACs, 2x USB-Cs, 2x USB-As, 2x DCs, 1x car port). Like its other DELTA 3 variants, this model also comes with a wider array of expansion battery compatibility up to a maximum 5,120Wh capacity using units from the DELTA 3, DELTA Pro 3, DELTA 2 Max, or DELTA 2.
It brings along a greater option pool for five recharging methods, too, including AC charging (taking around 56 minutes for full), smart generator charging (in the same timeframe), using an alternator charger (for around 1.3 hours), or connecting up to 1,000W of solar input (around 70+ minutes in direct sun). Lastly, you can use both an AC outlet and solar panels simultaneously to lessen its charging time further.
