As part of the final days of EcoFlow’s Home Preparedness Month Sale (with a bonus savings code), the brand has launched a 48-hour flash sale with up to $900 savings on four units. If you’re on the market for a higher-tier portable solution, you can score the 3,072Wh DELTA 3 Ultra Plus Power Station with a modular 500W solar panel down at $1,899 shipped, with the final savings automatically cut once placed into your cart. It’s down from a $2,799 full price, which you would have to pay $2,498 for buying the station and solar panel separately at Amazon right now. We’ve mostly seen this bundle discounted to $1,999 in 2026, though there have been some falls as low as $1,799, which last occurred in April. The deal here gives you up to $900 in savings for the second-lowest price we have tracked this year, putting your backup power needs into the series’ most advanced option. Head below to check out the full lineup of flash sale offers and be sure to also check out the full sale lineup here, complete with a bonus extra savings code.
The top option of EcoFlow’s DELTA 3 series, the DELTA 3 Ultra Plus power station can handle a lot with its 3,072Wh starting LiFePO4 capacity here that can expand up to 11kWh with batteries from multiple other stations, making it quite the versatile unit. It bears 11 output ports (5x AC, 3x USB-C, 1x USB-A, 1x DC, and a car port) which produce up to 3,600W of steady power, can boost up to 4,600W in a pinch, and even surge as high as 7,200W.
What’s nice here is that you’ll be able to utilize the solar charging capabilities with the included 500W modular solar panel (4x 125W), with the station having a maximum 1,600W input. From there, you can plug into a standard AC outlet or gas generator, use a vehicle auxiliary port as you drive, get faster on-the-go charging with an alternator charger, or there are two different dual options available (either solar + a generator, or solar + an alternator charger).
***Note: Unfortunately these flash savings cannot be stacked with other codes, with the final bits of savings cut from the tag once it is placed in your cart.
