Black Friday is Friday, November 27, 2026. Amazon’s Black Friday deals run November 19–30, through Cyber Monday, from 12:01 a.m. PT (3:01 a.m. ET) on November 19. , Amazon lists EF ECOFLOW Portable Power Station DELTA 2 Max at $1,028.99, with a deal badge: Limited time deal.
Cheaper in Power stations, and what changes
Things of the same kind for at least 10% less than $1,028.99, with the attributes the retailers describe differently. Their words, not our judgement: we compare listings, we do not test products.
EcoFlow lists the Delta 2’s energy storage (1–3 kWh, expandable) and its output (1800 W, with up to 2200 W for high-wattage appliances in X-Boost mode) as separate figures, so read both on a listing.
EcoFlow says the Delta 2’s LiFePO4 chemistry gives 3000+ full charge and drain cycles and 10 years of daily use until it reaches 80% of its original capacity. UL describes UL 2743 as the Standard for Portable Power Packs and says its scope limits the aggregate capacity for lithium-ion batteries to 20 kWh.
