For 48 hours EcoFlow is offering the expanded 12.2kW DELTA Pro Ultra power station + a FREE trolley at $5,599, more

59% off/$1,369+

EcoFlow has combined its ongoing RV Season Sale with its usual EcoCredits Monthly Madness promotion, which is kicking off for the final days in May and includes a 48-hour flash sale with up to 59% off discounts. Alongside the WAVE 3 AC and dual DELTA Pro extra battery bundle, the only power station offer during this window is on the 12.2kWh DELTA Pro Ultra Portable Power Station with an extra battery and a FREE trolley at $5,599 shipped, beating out its Amazon pricing by $400. While this bundle carries a $9,397 MSRP for the station and two batteries setup, you can more often find it starting around $8,799, with Amazon having only ever seen it discounted as low as $5,698 (Black Friday) and otherwise keeping as low as $5,999 in 2026. Outside of some 2025 exclusive deals, the 36% markdown here is a repeat of some former flash sales that cuts $3,200 off the tag for another chance at the best price we have tracked directly from the brand.

This EcoFlow DELTA Pro Ultra bundle gives you the starting 12.2kWh LiFePO4 capacity that its newer DELTA Pro Ultra X power station for $2,400 less of the price – though it can only expand up to 90kWh as opposed to the Ultra X’s 180kWh fully expanded capacity. Still, it brings more than enough power to your trips away from home as much as it does while supporting your home (especially with a Smart Home Panel 2), providing up to 7,200W of maximum output power, which also expands with the system up to 21.6kW. It comes boasting an IP54 dust-proof and splash-proof construction, able to withstand -4 to 113 degrees of a temperature range.

As you might expect from one of EcoFlow’s largest backup solutions, there’s plenty of recharging methods available to you here, including an expandable solar panel input from the starting 5.6kW to 16.8kW. There’s also the usual AC outlet charging, connections for an EV pile or gas generator, hooking it up to the Smart Home Panel 2 that unlocks grid and roof panel charging, or by combining multiple of these sources (like AC + solar).
